Hello
I recently purchased a Catalina 27. It had not been used in 6-8 yrs. The PO said they were told it has a cracked block.
So let the journey begin!!
I got the starter rebuilt,put in a new battery. It turns over and has spark. I hooked up a temporary outboard tank as the extinct fuel filter was full of junk. It turned over and fired once in a while. I checked compression and found zero in 1,2 &3, 4 had 90# ( Auto Zone has a loaner program where you purchase the compression tester and they refund your money when you return it.).
So far the diagnosis is exhaust valves on 1,2,&3 were stuck open. I removed the engine from the boat and have it at home as the boat is at a marina 4hrs away from where i'm at.
I took the head off and removed the valves after much patience spraying them with pb tapping them down turning the engine over with flywheel til they came back up and tapping back down.About 15 or more times until I was able to pry them out.
Thats all for now trying to figure out my next move!!!
