Hi Guys,*
I was wondering if anyone can help me, we bought a speed boat (second hand), all was great on the boat but thought we might as well send it in and give it a full service *( replacing the spark plug, filters etc. ) .it went well for the first few trips to the dam up until now! When the boat is at top revs 4700rpm it suddenly drops to 3700rpm. I then stop the boat and when i pull away again it goes like hell for the first few minutes but then suddenly the same problem occur? Can somebody please give me advise on what the problem could be or offer a possible solution?
It would be of great help.
Regard*
I do not know what the year model number of the engine is, Yamaha 150HP 2.6L V6*
