Any views anyone. I have now boat the boat and it has a Volvo MD5a. It turns but has litttle compression. I'm thinking valves or piston rings or possibly head gasket? What does anyone think and are these units any good once l've got it working!

If you watch big gas pressure in crankcase - replace piston rings (check piston pins)
Grind (or replace and grind) valves and seats in any case
