    1992 yamaha 2-Stroke 85hp tiller handle lower unit

    1992 yamaha 2-Stroke 85hp tiller handle lower unit

    The 2-3 times I’ve changed the impeller over the years ….. the shift shaft just didn’t seem right when everything was in neutral up top and trying to get the lower unit in neutral. I’m really starting to believe it was the bent straight pin and the shift cam all this time. The incident with my...

    1992 yamaha 2-Stroke 85hp tiller handle lower unit

    I won’t know for sure until I get all my parts in and assemble them. At this point if my sync is still off it has to be the midsection linkage shaft

    1992 yamaha 2-Stroke 85hp tiller handle lower unit

    I'm also wondering what else can cause the linkage to be off causing the noise ? I've been told to adjust the linkage near the power head but I run out of threads. When using the shift handle on tiller, the linkage is almost all the way in reverse before the noise stops while in neutral. The...

    1992 yamaha 2-Stroke 85hp tiller handle lower unit

    If I remember correctly, when I first bought this motor(5years ago) it always made clicking noise while in neutral and I'd spin the prop by hand. While motor is off of course. Fast forward to last week. My cousin slammed it into reverse while it was idling kind of high. I tore the lower unit...

    1985 20hp Johnson outboard conversion 30hp timing

    Changed out intake manifold and carb. Bigger throat on carb and bigger intake on manifold. From my understanding the powerHeads are the same. Now you have me wondering what would happen if I advanced the timing 🤔 Otherwise it runs great. Probably could afford to burn off more fuel. I have...

    1986 20hp port and polished head

    Been learning a thing or two about old outboards last couple years. Decided to build a little race engine for a small racing boat. Anyone out there have specs on porting and polishing intake and exhaust ports ? Am I pissing in the wind ? I already have done a intake manifold and carburetor...

    1986 Johnson 20hp with 25hp carb filing plug

    Ok, I bought a 1986 Johnson 20hp. Completely changed out all the fuel lines, pump and etc. Pulled down carb and noticed the main jet was crushed from previous owner. Couldn't find a 20hp carb to put back on so I was forced to put a 25hp carb. After doing exstinsive research and asking a few...
