Welcome to the forum......
WOW, a 2005 with 2 hrs. Is that on a new motor or the original hrs on the boat/engine.
I would absolutely take it for a test drive...but in Mn it getting cold now.
I would assume those 2 hrs would have been put on in 2005 after it was purchased????
If so, then it has sat for 6 yrs. Some seals would be shot, gas if any in tanks,lines,carbs is trash.
Any bearings might be gone.
check compression....with a 155hp I assume it's a 951. I think compression is around 125-135psi. wait for answers .....
Stored inside or outside???? Who knows what else could be wrong or on the verge?
Please wait for more definite replies from the experts here before purchasing.
If you are near Minnetonka, Mn then a member could help you decide...he is minnetonka4me
