Sorry for the long post, but I figured it was important to lay everything out to get comments and feedback that were targeted to my ask, which is how to try and get some factory support for my engine failure after my warranty claim has been denied.

I have a 2020 Merc 115 HP on my pontoon I purchased as a package with the 5-year MPP Gold warranty. Last Fall, I pulled it out and had it winterized – it was running great. This spring, I got it from indoor storage, cleaned it, and launched it. I backed the boat so the trailer was in the water but the front was still over dry land, disconnected the lights and winch strap/chain, and had my wife back it in very slowly while I jumped into the boat. She is not comfortable backing up a trailer, so she goes VERY SLOWLY. This is a newer concrete ramp redone a few years ago on a small lake in a sheltered bay/no wake zone. Once the pontoons were in the water in back and the water intakes were submerged, I started it up. I had my wife continue to back in until I could float the boat off the trailer, and I had her pull the trailer out.

Immediately after starting it, I noticed a strange ticking sound. I thought it might be the clutch not fully engaging or maybe something knocking inside the cover, but after a few minutes I realized that there was something going on that I couldn’t diagnose, and we pulled the boat back out. I took it to my Merc dealer the next morning (not the place that winterized it since they were not an authorized Merc dealer). Over the next couple of weeks, we determined that the knocking was a bent rod from water ingestion, and the engine was shot. Needs a new powerhead and a little over $9K. Merc denied the warranty claim because water ingestion is not covered.

So, this is where I am. I am looking for ideas and advice on the best way to proceed. I am still in a bit of shock as to what happened. From doing a lot of research, I know that hydro-locking could be caused by many different things. Too much oil in the cylinder when winterizing, rainwater getting into the engine while stored horizontally, water coming in the air intake from getting too deep, a lose hose in the engine cowling, slamming the engine in reverse while underway, etc. But, the most likely from what I have learned, is that the engine probably got too deep when launching, and water got into the lowest cylinder through the exhaust port and the damage would have been done instantly when I turned the key.

I get that water ingestion is not covered, but I have a real hard time calling what occurred in this case “operator error”. I’ve lived on the lake for 25 years, and owned fishing, wakeboard, pontoon, ski and many boats in this time. I have never even heard of someone blowing up an engine this way. I’ve looked through the user manual, and there is nothing in it related to starting the engine that mentions anything about the water level except one part that says to make sure the water intakes are submerged before it is started. I know there is a page somewhere that mentions that there is an operating range for the engine in the water, but nothing specifically related to startup procedures, prestart checklist, etc.

I know that this has been a design consideration for 4-strokes forever. I know some engines have flapper valves so water does not travel backwards up the exhaust and destroy the engine. So, I am having a hard time accepting that this was “my fault” and not simply a combination of a design shortcoming, a lack of knowledge (which I will admit), and a very poor job of informing the consumer of these design limitations. Before you Merc mechanics and “experts” jump on the bus saying I am just trying to avoid responsibility, let’s hear from the casual boaters who consider themselves knowledgeable on whether you would have guessed that launching my boat, as I have been doing for 30 years, could have resulted in a catastrophic failure such as this. Is this really something that everyone knows, or maybe something that only a small subset know could happen in the way it seems to have happened to me.

I have filed a claim with my insurance (Farmers), who I have been with for over 30 years for home, car, motorcycle, boats, PWC, snowmobiles, etc. I’ve spent well over 100K with them and have extremely low claim history. But, this type of engine failure is not covered by my policy. I can sink the boat, drive it into a dock, leave it on the street unlocked and it gets stolen, and that’s no problem – full coverage. But an engine failure due to accidently dunking the engine too deep when launching it is not covered. We are still working this angle and hope for a positive outcome, but it doesn’t look good right now.

I have also learned that Merc is notoriously difficult to work with in cases like this. While all of the manufacturers omit water ingestion from their warranty coverage, Honda and Yamaha appear to be much more likely to provide goodwill coverage in cases such as this. I’ve heard that covering this might be more the rule than the exception for them, while coverage by Merc is rare. I’d love some feedback if this is true or just a statistical anomaly from my limited research on boating forums.

I am currently looking at a $9k repair bill. The powerhead alone is over $6K. How can I get Merc to help? I have kept my correspondence with them cordial and have not threatened to sue or badmouth them on social media. I’d love to get full coverage, especially since I have 3 years of extended warranty left. But what about getting a powerhead, a new engine at their cost? The reallity is that the impact of helping me out at cost for Brunswick Corp is a tiny expense compared to a $9K expensive to me personally. Plus, I’m still paying off the loan for the boat/engine I took out 2 years ago as it is.

Who has gotten coverage above the minimum required, and what should I ask for, what would increase my chances of being successful? I know my best bet is to find a great dealer that will go to bat for me, but my dealer is my dealer, and they have been disappointing to say the least. So, what else can I do? Has anyone had success and if so, would you mind sharing the secret recipe? Anyone want to share a letter that they have sent to Merc that seemed to do the trick? Phone numbers of people who have made legal challenges and succeeded? I don’t want to invest a lot of money in legal fees, but I wouldn’t mind getting a lawyer to send a letter, especially if I were able to start with a successful letter than one of you had written that worked.

Thank you in advance for your assistance.

Warranty covers materials and workmanship. Not abuse

Water ingestion falls under abuse this is where your boaters insurance comes into play. call your insurance company

Hi. With the greatest of respect…my advice to you, after reading what you’ve written…is to immediately delete this post altogether. If you are in a warranty claim dispute currently…there are at least a couple of things stated above that the manufacturer could reference easily, then inform you of a refusal to the claim. The insinuation of possibly being submerged and putting oil in the cylinders to winterise…just those two alone…will get you in trouble for sure.
Best of luck.

Too Bad you didn't have the Merc Dealer do the winterizing.
Bent Connecting Rods can occur when a Liquid is ingested while the engine is running at speeds higher than Idle. I guess if someone poured a pint of Fogging Oil down a Carb in less than a couple seconds and the engine was running about 1500 - 2000 rpm, it would have stopped instantly and bent a Rod, but far less likely to do that at Idle. I wonder if the Flywheel Key sheared as well?
I am curious as to how to launch a Boat and getting the engine too Deep, the boat floats off the trailer when the water gets deep enough. If the engine is so low when the boat is sitting at the Dock, so as to fill a cylinder with water...

I appreciate all advice, but really don't understand. I didn't insinuate anything. I did list possible causes of this type of failure, and from researching, what I think was the most likely, getting the engine too deep at launch. Water got in engine, that fact isn't in dispute. What I question is how, and if attempting to launch my boat as outlined constitutes a case of 100% operator error.

Well, I plan to get video once boat is fixed to satisfy my curiosity about what likely happened, but when the front is still on the trailer, that puts extra pressure on back and would force it to sit lower in the water. As the trailer gets deeper, the front sinks in the water and the whole boat flattens out. I don't think there would be an issue floating at the dock.

Surely you would know if you put oil in the engine cylinders or not. Anyway. Best of luck with it. But I’d still get rid of your post. Just trying to help.

So I am curious how do they think you got water ingestion? If your wife backed in slowly highly unlikely water was driven into the powerhead. And if you started it when the water intakes were covered that would prevent water from going up. I would look somewhere else than the boat landing where the damage happend.

It was fine prior to being Winterized?
Yes, ran great. I dropped it off to be winterized one afternoon, and the following afternoon it was ready so I picked it up and took it to my storage place a mile or two away that evening. And, if the winterization place did their jobs, they would of identified the issue as they have to run the boat to get the gas stabilized anyhow. The ticking noise from the bent rod was very noticable - you could not miss it. I obviously did not start it when I picked it up as that would of screwed up the winterization (blowing any fogging oil out). I was a little annoyed and surprised when I picked it up though. I asked for the oil to be changed along with the standard winterization service. When I got there, they said they checked the oil and it looked like new, so they didn't bother with the oil change. I found that really curious and a little irritating because I had put quite a few hours on it that summer and did want the oil changed. At a mininum, they should have called and asked me. Needless to say, I am not going back there agian. It seemed strange that they wouldn't take my money and do all that I asked but maybe they were actually trying to do me a favor, were lazy, forgot, etc? I don't really know. Looking back on it now, it does make me a bit suspicious. I mean, if they did something by mistake and knew my motor was destroyed, maybe they didn't feel right about charging me for an oil change too. My issue is that there would be no way to prove what happened, or even when it happened so I haven't even approached them about it. I assume something happening during winterization would have an extremely low possibility.

Other than that, nothing unusual. I stored it with the engine vertical in an indoor facility the day I picked it up, then picked it up, cleaned it and charged the battery and launched it EXACTLY as described about a month ago. Nothing out of the ordinary in any of that, just like I've done for the past 25 plus years. It hadn't rained the one night it was outside after I picked it up and before I launched it either, so while I know rain water could cause issues, I don't think that a possibility.

I did hose the boat off, but mostly the inside to get the floor clean and get rid of the dust from storage. I did spray the top of the motor off mostly because there was some splatters from me spraying the boat interior off, but noting that I think could have forced water into somewhere it wasn't supposed to be. I am seriously grasping for anything that could have caused it just to make sense of this. The engine getting too low just seemed like the most likely possibility based on all of the possibilities based on my situation. As I mentioned, once I get the boat back I am going to carefully video and document how low it gets on that ramp when I launch it. If there is a time when the engine dips real low, then I will know that that was at least a possibility.

I think the scenario where my wife backed it up slowly and the back end happened to be too low at the moment I started the engine the most likely scenario. I don't think the water intakes being covered would do anything to prevent water from being ingested through the exhaust though. The way I understand it (only from research on forums such as this) is that if the engine's lowest cyclinder is lower than the waterline when the engine is started, the water can go up through the exhaust and when the valves open on that cylinder, standing water enters the cylinder and hydro-locking is nearly instantanous. Some people have stated that they thought the engine would stop at that point (wouldn't run or continue to operate), but that is not my understanding. It can run if the damage is not too great. My engine just sounded like there was something tapping or rapping somewhere, which I was told was the bent rod striking something. Otherwise, it started right up. I only operated it like this for a few minutes, and never more than 30 seconds or so while I looked for possible causes. This is just from what I have been able to understand though - I'm not a mechanic.

I think the odds of this are miniscule though. I've never heard of, nor has any of the friends I know with pontoons, anything even close to this. I'm from Minnesota, and pontoons are probably sitting at the dock of 90% of homes on my, and most lakes so between everyone on this lake, there are thousands of boats launched and retrieved every year from this (the only) landing. It's a newer concrete ramp, so no dips or rock piles or anything that could have caused an issue. I'm the only person who has ever had a problem like this that I've ever heard of around here.

Otherwise, something happened during winterization. I have zero way to prove that or know if it happened. Or, someone sabotaged my boat that really knew a lot about how these engines worked and knew exactly what to do. I am still married after 30 plus years and don't have a girlfriend sneaking around in the background, so I don't have anyone that I know would want to get me :). All I know is it was fine when I took it in to winterize it, and the next time I started it, I had a bent rod and a destroyed engine. I know my storage guy well - hobby farmer who rents out one barn in the winter, so I know he didn't go joy riding. I also only had the boat at the winterization place for about 24 hours before I picked it up, so they could not have taken it for a spin. Believe me, I have tried to account for every possible scenario as this seems so unbelievable.

Video of me launching it when I get my boat back will tell the tale about whether that could have been an issue. If not, then I might investigate the winterization place a bit more. I think I would have a better chance of winning the lottery than proving anything or getting any money back based on a far-fetched theory that they messed up my engine. I don't think I would waste much time on that.

Again, I totally understand that you are trying to help and really appreciate it, I'm just not following your train of thought. I didn't put oil anywhere, I didn't do anything to the motor myself. I had it winterized and then launched it the next Spring. What I was saying is I understand that some people like to squirt a little motor oil directly into the cylinder along with or instead of fogging oil as a winterization step. I have heard that if too much is used, that could cause the same failure. I was just saying that this is one of the possible causes for the problem I had. I think that is really a low probability, but if it happened, I'd have no way of proving it anyhow, so I don't even plan on barking up that tree.

How did they determine that there is a bent rod ??
I am not sure, but the initially told me it was bent, then when Merc declined warranty coverage I asked for them to at least provide me an explanation of how it happened, etc. They tore the engine apart. I think it has to do with measuring where the piston is in the cylinder, but I honestly couldn't tell you.

Did you get any type of Bill/Receipt from the place that did the Winterization?

Yes, haven't looked to see if I could find it, but I do have the credit card payment on-file. Not sure what good that would do though? I couldn't prove it even if it did happen there.

No problem. Yeah. So it’s not recommended to put any fogging oil or oil into these modern engines…not like the older carb engines perhaps. Any fogging oil sprayed or put in these plays havoc with them and their sensors at the least.
Not sure how water would get into this to do any damage, unless it was submerged. They even have a flushing port for running water through them without damaging or entering the combustion area. Be very hard to get water in there, other than it being submerged or a compromised cylinder head

Thanks - I understand now. Yeah, I didn't do anything myself, but was just recapping some of the possible causes for my issue from what I have read in forums like this as I searched for answers. The only one I can think might of happened was the engine getting too deep because everything else seems so unlikely. I never sat in the back of the boat and watched how deep my engine got when launching, but have been doing this for many years and never even noticed anything that made me think that the back end was really low. When I get the boat back and get some video of me launching it at the same ramp, I should know if this is a possibility. Not that it will change Merc's willingness to provide me any assistance, but at least I will know and can make sure it doesn't happen again.

I think, to be fair on you…it might be unlikely that the engine has suffered as a result of you backing the boat into the water. The engine would need to have been totally submerged fully and the back of the boat still strapped down to the trailer, you’d think. Even half submerging they engine wouldn’t usually allow water ingress into the cylinders. Have you done a compression test on it yourself ? Just to check the head isn’t compromised ?

I don't have the boat - it's been at the dealer ever since the failure. They completely tore it down and so I am kind of at their mercy. I have a copy of all the pictures which I requested to help with my insurance claim, but don't think there is anything I can do at this point.
