I have a 2012 Yamaha 250 sho. Power head went lost compression in cylinder 6. Got a price for 14 thousand to put a new one on. Are there any other alternatives ? Has anyone used a refurbished one? If so what's a good company to deal with. If block is good what's average price of a rebuild? Motor has less than 250hrs on it. Any help would be great. Very frustrating.
