I just bought one used from a dealer today,to be installed on my boat monday of next week.has about 100 hours on it.looks like brand new.My question is how well do these motors hold up and do they share the power head problems that i have been reading about on the 150's.I think i got a good deal on the motor if not a lemon,$3000.00 straight up,n/tax.Haven't the 115 had a great reliability record. thanks waynebo
