Man thats no good. I took mine on a 65 mile offshore trip and it ran like a top all day long. My issues were the carbs.

I hate to even admit this, but I ended up putting them through the dishwasher twice all taken apart, with super hot water (double heated option). My problems vanished. I used no soap and blew everything out and dry with compressed air.

Gotta be the carbs man

I find it odd that this particular motor tends to have similar issues with other owners as well!

Why did this motor have to come on my boat!
