The outboard is a two stroke non EFI. Just purchase the boat and the previous original owner had not change out the hoses but did state that he always used ethanol free gasoline. I can not locate the fuel filter and I don't think it has one. I have not checked the vent and will do so. I contacted the owner last night and he stated he only used the boat once last year and it could be the gas.

The engine will only kick over if the choke is fully open and the throttle is open a little. This is when the engin is cold or warm. Once it kicks over I have to get into gear quick or it dies. Once wide open it does fine. Just when I place the engin in neutral it will not idle and stops running.


Ya, this is a classic case of a boat that has been sitting and not used enough. You need to do a de-carb to clean the engine out.
