Accelleration problem

Question
I have a 1996 Maxum 21' with a Mercruiser 3.0 engine. I bought the boat used so I don't have the history. When I am throttling up the engine falters then accelerates. Cruising speed and top end are fine. This problem is terrible when pulling a skier. Idle is also very rough.

Answer
Hi Jeff...thanks for selecting the undersigned to reply to your question.

It sounds as if you might have a carburetion or linkage problem, which may need an adjustment or more. Best you consult a reliable and qualified marine mechanic to resolve. The cost will likely be worth it.
