    Old 2-Cycle Mercury Oil Leak

    I had a post I started about this last year but I wanted to start fresh. The motor is a 1989 Mercury 90HP outboard, 2-cycle 3-cylinder For the last few years, it seems to have a slow oil leak. Slow enough that the tank isn't running low or anything, but fast enough that theres always oil...

    Dust Cap Woes

    I agree, it doesn't make sense. They're so tight when installing that half of them get destroyed and I have to go grab another one. Yet as tight as they are, driving about 20 miles pops them right off. It doesn't really make sense.

    Dust Cap Woes

    We've had this trailer for 30+ years and only recently did this start happening. Recently meaning last few years but also I barely use the boat these days so it's been maybe the last dozen or so trips. If the issue was that I somehow packed the grease in wrong, and the hub was overheating...

    Dust Cap Woes

    The craziness continues.... First off, the grease that squeezed out was just a little residue that got on the inside of the hub when I topped it off. There is plenty of space inside the cap. Also I'm not doing the same thing over and over. I keep changing it up but still get the same results...

    Dust Cap Woes

    I haven't spent anything on adhesive. On caps, since this problem started I've probably gone through 8 caps? The caps are super cheap but the issue is more, they fall off right away so I end up putting my exposed hubs underwater so if I just keep throwing cheap caps on, I'm going to ruin my...

    Dust Cap Woes

    Here's what I did. I don't know if it's going to work, and I suspect most of you aren't going to like it. But I feel like I was out of options. I took my last unused cap, I got it started.... not fully seated, just "in" all the way around, but still sticking out by about 1/8 to 1/4 of an inch...

    Dust Cap Woes

    Yeah I'm about ready to give them a try, I'm out of other options. But where do you get them? I don't see any stores that have the normal caps, having rubber boots in stock?

    Dust Cap Woes

    So i made my last post, and i drove to the river to put my boat it. Boated around for a bit, yanked it and drove home. I was feeling pretty good. Then yesterday, I was walking around my driveway doing something else unrelated and saw this: :mad:🤬🤬🤬🤬 I don't understand how they can be so snug...

    Overheating at idle, cool as a cucumber at speed

    If anyone is interested, while I was doing all this, I did make a video specifically for "how to" replace the impeller. There were tons of these videos already, so now theres one more :)

    Smokey Engine - Air/Fuel problem or Oil/Fuel problem?

    I've got a 1989 Mercury 90hp and these past few years, it's running a lot smokier than it ever used to. Looking in to it a bit, smoke can happen from a bad air fuel mix on a 2-cycle engine. It can also happen from a bad oil-fuel mix going in to a 2-cycle. My motor is oil injected, so it's...

    Steering Slack and Stiff Steering

    If you start squeezing grease in there with a gun, will it have a place it can release out of somewhere?

    Steering Slack and Stiff Steering

    90hp 1980's mercury. There are fittings but are they actually steering fittings or are they trim system fittings? Regarding the rod, isn't the seal going to wipe that grease right off when I turn? Is any of it actually going to get inside the cable housing?

    Steering Slack and Stiff Steering

    I'e watched a few videos where they are greasing all the fittings on the motor with a grease gun, but in the comments, everyone is saying how those fittings are for the motors turning pivot and the trim system, not for the actual steering cable/rod. Is there a fitting somewhere specifically for...

    Dust Cap Woes

    I bought another set of caps today to replace the latest one that fell off, and I eventually got it in there without any modification and from what I can tell, no damage either. Hopefully this one stick and this problem goes away! The first one went in within 5 minutes, so now I have a spare! As...

    Steering Slack and Stiff Steering

    I just put my boat in the water for the first time this year, today. Yeah, in September :( The steering is very tight. I suspect it just need a lot of fresh grease. Is there a specific type of grease you need to use for steering (like suspension grease) or is it just regular old thick marine...

    Old Mercury Leaking 2-Cycle Oil

    I've got a problem. My motor leaks 2-cycle oil. It's not a big enough leak that it affects the operation of the boat. If you fill the tank, it will still take a very long time to run out. But it's getting everywhere. Every surface inside the cover is coated with oil. If I tip the motor up...

    Overheating at idle, cool as a cucumber at speed

    Update: I started to feel like I was really at an impass where I couldn't know if there was really something wrong with this motor until I went and opened it up for a while. So I did that today. It was barely running at first, I had to push the choke button non stop. But eventually it started...

    Overheating at idle, cool as a cucumber at speed

    Ok since my last post, I went to west marine and replaced the thermostat. So new impeller, new thermostat, new hose for the water waste cooling water, and I also blew out the clean looking passageways as best I could with an air compressor. And despite all that, its still getting very hot to...

    Overheating at idle, cool as a cucumber at speed

    Taking a closer look at that hose in the daylight, it wasn't just kinked, it was double kinked from being jammed in the housing of the motor when i closed it. I was able to get some vacuum hose to replace it at NAPA for like $3 so that's all good. Also with another hour of messing around, I...
