Re: MERCRUISER V8 305 ONLY 3000 MAX RPM AND BACKFIRES HELP?
WELL HAD CARB REBUILT DONE, RUNS GOOD IN NEUTRAL BUT IN GEAR STILL RUNS BAD,ONLY HITS 3000 RPM BAD BACKFIRES, SLOW REPONSE. SO I FOOLED AROUND AND AT 3000 RPMS IN GEAR I TRIMMED UP PROP ALL THE WAY. RPM WENT TO 4500 OUT OF WATER. THIS CAUSED THE STEERING WHEEL TO SHAKE SO I TRIMMED DOWN AND AND THE BOAT WHOULD NOT MOVE! STILL IN GEAR AND 4000 RPM VERY STRANGE? SO I GOT SCARED SHIFTED TO NEUTRAL AND SHIFTED BACK IN GEAR. BOAT RAN LIKE IT DID BEFORE 3000 MAX RPMS. I DID THIS 2 TIMES SAME RESULTS. I ALSO FELT BAD VIBARETION IN LOW SPEEDS WHEN IN GEAR. WHAT THE HELL IS THIS BOAT DOING? ANYONE HAVE A THOUGHT?
