Hello Everyone,
I recently acquired a 74 newport 30 with an A4. Unfortunately due to deferred maintenace and neglect the boat was allowed to accumulate a fair amount of water in her cabin. Needless to say the engine got wet. Up to the point where the starter had water damage. The engine had set up. I sprayed a generous amount of penetrating oil into the cylinders, and after a few days soaking I was able to get the engine to turn. I was dumbstruck to find no oil in the crankcase. I pulled the carb, intake/exhaust manifold, and gained access to the vale train. I was pleasantly surprized to see that it was very clean inside. I manually turned the engine (the starter was inoperative) and saw that the valves were moving. A good sign at that point.
I repaired the starter, filled the oil to dipstick full level, then did a compression test. The results:
cyl 1...0 psi dry...0 psi wet
cyl 2...0 psi dry...90 psi wet
cyl 3...60 psi dry...110 psi wet
cyl 4...110 psi dry...160 psi wet
I settled for pulling the engine for an overhaul. Next day I arrived to begin the extraction and I found that all of the oil...about 2.5 qts... was in the cavity below the engine and in the bilge. Hmmm... rotted oil pan? I haven't done a full assessment of the engine yet.
I set to the task of removing the engine. I have the engine out of it's mounts and in the gangway. I decided to have the marina lift it out of the boat which hopefully will be this week. She is on the hard and that 8-9 foot drop to the ground (at the transom) would have made it a daunting task.
I was informed that the marina had a used A4 that is reported to be in running condition. I was told that they would make a definitive assessment of the condition of the engine.I asked, but they didn't give me a price on the engine. They want to inspect it first.
Okay...finally my quetions. Based on what I have described and going on the assumption that the major components are still good (i.e. the head, block, manifold,etc...) would an overhaul be cost effective? (I see that an oil pan is $200.00). And, what is a reasonable amount to pay for an engine you have no history on, other than to say it runs. No idea if there are any upgrades to this engine...electronic ignition for instance.
