1993 Johnson 60hp, hit a stump & ripped the prop,destroying the prop bushing. Put a new prop on but now it will over-rev at 7000rpm and it seems the lower unit is slipping. I have tried another new prop and same thing. Are there bushings/grommets in the lower unit that would allow this...
I am thinking about purchasing a Nissan 9.8 four stroke with electric start. I want to upgrade the horsepower. I am told that it will require re-jetting or different carb. What does an upgrade cost? How much horsepower will I gain? What will the performance be? What kind of Cost?
