    Power Valve Broke Again

    The power valve broke for the 3rd time in two years on #3. Happened in June 2010, last July and now again. Infricking credible. Both times replaced with OEM part from boats.net. Probably about 50 hours on each valve. They break right at the stem, and the valve dropped and went out the exhaust. The only good thing is it only damaged the piston. Sure looks like a casting flaw where the valve broke
