Great! They had to order a few parts from their supplier which took 3 to 5 days for Crowley Marine to get the part, but their website indicated what was in stock and what wasn't, so there were no surprises. Also, I've had to call on a few orders, and always got a live person after a short hold, and the people were always knowledgeable and helpful.

Problem fixed: Pulled powerhead and mid section to clean

I learned that the gaskets are critical. I had two tears in the new gaskets I put on (I wasn't careful), and when put back together, water was spraying out of the side of the engine where the tears were. Also, because of the 30 year age of the aluminum block engine, some bolts will strip very easily. Be careful. I've had to buy an odd-sized drill bit, a tap and thread repair inserts for a few bolt holes. I went with Helicoil, although there are newer, but more expensive, options available.
