We have an Atomic 4 on our sailboat. It has been the worst nightmare I''ve ever encountered. I have definitely rebuilt the "outside" of the engine, i.e. carburator, alternator, starter, coil, distributor; basically spent about $1,800.00 to get it running, and the thing is still dealing me fits. We did a compression test, and there was no compression on two cylinders. We think its a blown head gasket. I tried to take the head off, removed the bolts, but the head is "fused" to the block. Sources tell me that it has gotten too much heat, and we shouldn''t put another dime in it and ditch it. My question is, should I continue, and what do I do to continue? Or, should I just buy an outboard and boogy. We are currently in a slip/marine that is not "ours", even though they haven''t figured out we''re there yet. I need to move the boat, basically about 85 miles back to our slip. Suggestions?
