240 Seary 2001 model sports cruiser
by Les Simonds
I had my boat at marine mechanics, they just replaced sea water pump, replaced distributor cap and rota tor button all leads and spark plugs, replaced map sensor to 5.7 ltr mercruiser TBI engine and now the engine will only rev to 2000 rpm and is seems to be missing and vibrating when try to increase revs , they also replace gearbox and drive shaft, universal joints and bellows
It seem to me that when give engine more fuel to go faster it plays up, I have had the injector replaced also about 12 moths ago and the boat then ran well,
would it be injectors or electrical fault with injection system this only played up after the map sensor been replaced. any help?
