Upcoming problem?
I have been taking my 1991 V20 cuddy out at least 1 day every weekend for the last 5 or 6 weekends. I am boating on inland lakes, and spend most of my time pulling kids on the water toys and skis. I have a 2007 Mercruiser 4.3 litre carbureted engine with a 1991 Alpha One outdrive. The boat has been running very nicely. However, on pretty much random instances when I throttle down to get the tube/skier up, the engine will bog down to idle, but not die. Then, after all is set to give it another go, the motor runs just fine.
Tank was drained and cleaned in 2007, and fuel filter replaced annually since. I have not done any other "tuneup" type of maintenance to it. Any thoughts on what I should be looking at and doing would be appreciated.
