Hi,
I'm wondering if I need to rebuild my engine, or there are other issues that I'm not seeing, here's the history:
I have 120, 115, 110, 110 compression in the cylinders. I used an Autozone loaner compression tester which looked well worn, I'm willing to bet the compression is a little better than that.
The clock say 950 hours. There is a lot of oil from the back of the engine near the head, I'm assuming that the head gasket is leaking and causing the low compression in # 3 and 4 cylinders. I figure replacing he head gasket will even it out and since I need to pull the engine anyway to fix the stringers, I might as well rebuild it and replace the crankshaft water pump seals. Engine rebuild will be a good winter project. Engine runs well right now.
So now I'm wondering if 950 is a lot of hours for a boat? I looked in the spark plug holes and the cylinders are caked with carbon, I figure this to be a lot of low RMP use and probably misadjusted carb issues.
This is my first boat, information from you all is invaluable........
Thank you very much
