Well, used the boat quite a lot the last few weeks. What a joy and other boat owners really seem to like it!
Did some work on it as well; put some fresh SAE30 oil in it, replaced the V-belts, checked the water pump and ordered a brass water filter housing.
The COV is leaking quite badly, especially when it's on low compression. I want to replace it by a fixed one which sets the compression ratio at 1:17 (with glow plug) from stationaryengineparts.
Just a question; does the inner part of the original COV have to me removed from the head or can I just screw out the original one and replace it directly?
