HELP! Salt water in my 130's

Re: HELP! Salt water in my 130's

I definately won't get in the way of you Marine techs, you're doing fine.<br />However, to grab mhoyt01's attention that all may not be lost. Fact is, if a cylinder is injected with water, carbon will break loose from the top of the piston. This carbon can lodge in between the exaust valve and its seat, creating a temporary loss in compression. Hence the need for a leakdown test, to determine the location of the compression loss.<br />Either way, I'd be very prone to get the motors free of any and all contaminates and run the heck out of the motors for an hour or two before I'd condemn them. You may even find that the compression will read normal after such a hotlap.<br />You only have a great deal to gain and not much to loose by giving it a try. So, let us know how it turns out. <br /><br />Would you Marine techs agree??

hello<br /> I would have freed the motors of contaminants at the outset. I have found that decarb spray actually emmulsifies with water and will held dewater the block/crank assy. so I decarb the sunk/waterfilled as a mater of course. the compression numbers across the cylinders not engine to engine are to even for me to consider a valve hanging problem. I would leakdown test it and go. actually I would have dewatered it ran 10 gallons of gas though it from a seperate tank and gone on.the crank/rod assmbly will tolerate water in the fuel better on a 4 stroke because the incoming air/fuel mix does not have to lubericate anything.<br />with a water mist however it will cause valves to rust. hence the decarb or at least fogging oil. that is the beauty of our work. motors dont fail gradually if its major. when the valve has had enough and is going to burn it does it rapidly. when a piston is going to melt and blow a hole through it it will last maybe 3 min. anyway good luck and keep posting

Hey guys,<br /><br />Well, I would run them, but since the incident, they simply won't run.<br /><br />I wish the fuel/water separators worked that way, but there was just salt water everywhere.<br /><br />I have taken it to a certified honda tech and he said teardown time. In an effort to save money, he told me I could pull the long blocks, then remove the heads, and he would step in at that time.<br /><br />My brother and I pulled the long blocks off the two motors in about 9 hours sat. I'm going to pull the heads tomorrow. Meanwhile, while the engine are off, I have to pull the center console, leaning post, bait tank, rear seat, and deck in order to remove/replace the 140 gallon gas tank.<br /><br />Woo hoo, let the good times roll.

Sucks to be you, dude. At least you can look at it as a learning experience. I'd say all is not lost with winter coming etc. but you have 365 days of summer there, so back to statement No.1

I'm so sorry, I swear I made my username BEFORE I read this post. <br /><br />

Just a reminder. Clean or replace the whole system, hoses, filters, hoses, vents, etc. If ogiginal equipment, they are not worth working with anyway.<br />I have seen those that did the tank and paid for the engine and clogged it up instantly when they ran it again bacause of the hoses and filters being fouled. Or were back into it bacause of reusing old parts.
