Re: Crownline Roll Call!!
mtbr00x, Volvo or Merc? Volvo's safe circuit will limit the engine RPM to 2500 if it detects an engine fault. If engine is EFI/MPI, it will disable 1/2 of the injectors at the engine cylinders or throttle body and fix the timing to 8 degrees BTDC. Merc's Guardian can limit engine RPM's as well. If you have an engine alarm on either Merc or Volvo, you should have an audible alarm though. Other thought is a dirty hull can limit engine RPM's and thus make it difficult to plane. Other than that, I'd look at the engine....idle smooth? last tuned up? fuel filter, fuel pressure, fuel vent clear, exhaust flaps where they are supposed to be (exhaust not obstructed), etc
