    How to drop gear housing on 1979 20hp

    I just picked up a Jon Boat with a 1979 20hp which needs a new impeller. I have the parts, but everything I read says there are two bolts but I can only find one just above the propeller.

    Force 125 (1987/88) Prop Question

    Re: Force 125 (1987/88) Prop Question This is the way I got it... looking at the Clymer book I have, everything is there except the cone thingy which reminds me of the cone in front of a plane prop on a cesna.

    Re: Force 125 (1987) Cylinder Help I just took of the lower manafold/reed and before I did, I observed a lot of fuel/oily build up on the bottom and it seems to have been dripping off on the support plate area for some time. The image doesn't show it well, sorry I tried a few times with my...

    I had a much lower compression on the #4 cylinder than the rest which was 135lbs and the rest where very close to 145, after cleaning carbs and everything else I could do on the easy and cheap, I still had poor (warm) idle and cutting off issue. So I decided to pull the cylinder head off...

    I just picked up a Bayliner with the 125 on it, made first trip to lake and have some issues. Before taking to lake I checked it out running in the yard with muffs and tried cleaning the carbs and setting the throttle cam link to a point where it would just stay running in neutral as it was...
