Today I took a boat out I recently bought that had not been out in about 18 months before today.

I went through the motor and changed the plugs and emptied out the old gas that had been in there the whole time.

Today, it cranked right up and sounded good as it was warming up. Well as I began to head down the river at 75% throttle all was good but when I opened it up it immediately bogged down to about 30% of full speed, like it maybe was starving for gas. Well we fished a while near the landing and once we cranked it again it went directly to seemingly run at about 30%, even though we kept the throttle at full strength. All of the sudden it opened up and ran about 7 minutes at full speed and sounded really good and then it bogged again like previous.

Does this sound like a fuel issue or a firing issue? I have comments to both sides of the argument.

I do appreciate any help,

Ricky Hinson
