compression is good on all cylinders. Sounds like a power pack too me. What yall think??

I have a yamaha and it did the same thing,brought it to the shop and mechanic said it was a dirty carb,bad gas etc,drained the gas and cleaned carb and 178 dollars and been fishing happily ever after.Good Luck

before he bought the boat previous owner had the carbs were cleaned. new owner changed the old gas line and bulb bc the old one was leaking at the nipple on the gas tank. though it might be air causing this problem but it isnt.

Yep, dirty carbs, my Yammy 50 hp 2 stroke did the same thing, get the carbs cleaned.
