I have a 1995 Johnson Limited Edition, 200HP outboard. At end of this boating season the motor made astrange noise and I immediately trailered and took it in for check. The mechanic said I detonated the piston. The piston and power head are aparently ruined. There are holes in both. It was explained to me that this was caused by running too lean or out of fuel. I run with a tach. I have been using a 4 blade OMC prop <br />(Viper 22 pitch - not sure right now on pitch?) . My boat is a 20'4" Concord and at extended full throttle the motor tachs at 6000. 95% of my boating is pulling knee boarder and wakeboard at 3000 rpm. Has anyone else blown a power head on one of these engines? I hate to spend $3500 plus to rebuild an engine prone to this catastrophic failure ove fuel too lean.
