"My son-in-law picked up a nic
"My son-in-law picked up a nice 94 Maxim 2000 sr2 with a 4.3 mercruiser with alpha one drive. It's happened a couple of times that while cruising along part throttle the motor started revving down and up a bit while slowly losing rpms and speed. When I was with him he pulled it back into neutral and revved it up a few times just fine. When it does this the motor sounds just fine, no missing or sputtering or coughing. I thought he was horsing around until I looked over and his hand was not on the throttle. When he first got it it was checked over and fuel was changed out and a fuel filter was replaced. I'm guessing some kind of fuel problem. Any ideas??"
