While out on the water the other day, after a few hours of normal running and stopping, I fired up the engine and went to proceed as normal only to have the motor bog down and shut off once I got it past idle. We limped it in under idle and checked it out. Checked all fuel lines, changed fuel filter, cleaned carbs, changed spark plugs, still to no avail. Here is the catch... when the boat is on the trailer on muffs it runs beautifully, at idle, in gear, out of gear, low med high throttle, sitting in neutral. No issues whatsoever. As soon as we put it in the water it wont even sit in neutral at idle it bogs out and shuts off. Pull it out of water put it on muff fires up and runs fine. Just wanted to poll the gents on this site before shelling out to take it to my mechanic. Thanks for any help!
