[C320-list] repower

[Bill Carr]

    I only have 1100 hrs. on the Perkins I was certainly hoping to have another 10 years. Last season I began to lose the top couple hundred RPM if I would go full throttle. Then after not being on the boat for five months it wouldn’t start this January. I had researched the RPM loss last year and came across Indications and exhaust manifold blockage May be the culprit. I scheduled with auxiliary engine services to determine what was wrong when Harold determine the compression was below Perkins recommended minimum pressure. I don’t have a diagnosis as to the loss of compression I’ve always maintained the oil and filter on schedule. Perhaps the increased back pressure cause excess wear.

They suggested their Beta 30 and said it would cost about $10,000 plus $800 for the engine mounts sized to fit the C320.  These are rough numbers since I didn’t get too serious with the quote.  I think I can nurse my for a few more years, but I’ve been battling a chronic overheating problem.
