I am in need of some advice on possible reasons I melted down two engines this summer. This is not the first boat I have owned, and owned my previous boat for over 15 years with no problems, so I know how to maintain them. I have a 1986 20' Bass Buggy pontoon boat that I had these two motors on...
I have a 1971 Johnson 100hp o/b. It seems like thoughout the RPM range it will skop or misfire. Sometimes it will run great and sometimes it will not. It has me confused b/c of the inconsistency of the problem. It will run differently on the same tank of gas even. Any thoughts.
