Have a new to me 2003 yamaha 40 4 stroke.
I boat the engine yesterday and ran it for the first time today. It was winterized prior to the sale.
It runs great at a low idle and can get up rpms under no load. When in the water, when I throttle it up it bogs down and cuts out. If I nudge it up slowly, eventually I can get it up on a plan and run like heck. If I power down and try to power up quickly, it bogs down or completely stalls out.
Any thoughts?
Bob
