I'm new too
I'm considering buying a boat powered by a 1974 A-4 with about 2000 hrs. A pre-purchase inspection showed compression for all 4 cylinders to be about 112 psi. Information somewhere in the forum gives 85 - 115 as an acceptable range, so I just want to double-check that I'm reading this correctly and that the test results indicate a good engine with a long expected lifespan.
If I buy the boat, I expect to make good use of this forum!
