I have one on order. Just planning ahead. Sealing surface feels and looks great. I have no clue of the dimensions to put a dial bore mic in there.
I’ll mic the old and new o-ring when it gets here. I noticed when pulling bearing housing it slide right out with minimal effort
Appreciate your...
Just an update. Assemble LU this weekend. New dog clutch , straight pin, cam shift , plunger pin did the trick. All the linkage was A OK Thanks for all the feedback back guys.
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...
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.

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...

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...
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...

You may find some answers here. I did the conversion on my 86 20hp last year. Man does she have some spunk!!
I have a 1986 20hp Johnson manual start and I'm in the process of locating a electric start motor for parts to convert to electric start. What year and horse power motors will work. I did a little research but would like to confirm with you guys. Y'all had helped me a while back with some firing...
