Hi again, this is my second thread in regards to my outboard. After de-carbing my engine and still having too low of compression(85lbs while the others are 125-130) in my #2 cylinder, I have decided to try and fix the problem myself.
BRIEF HISTORY OF OUTBOARD: I bought it from a seller who "claimed it ran great. He bought it from his father-in-law after it had been sitting for several years. The seller admitted he knew nothing about boats and all he did was put oil in the injection and fuel in the tank and ran it several times. I brought it home and put it on the muffs. Immediately, I get a constant beeping sound and then a few minutes later, got the overheat buzzer. I turned off the engine and later replaced the entire water pump and both thermostats. Now it doesn't overheat, but the oil-injection system has an issue. I'm not too concerned with that right now since I mixed oil with the fuel for the time being. I'm guessing the damage to the #2 cylinder was a result of overheating from the lack of oil.
I have no real experience with working on outboard engines other than the basic maintenance stuff that anyone can do. I lost a lot of money from purchasing the boat and motor from a dishonest individual. I've invested too much money into the purchase of this lemon and can't afford to pay a mechanic over $1k to rebuild the bad cylinder. Based on the information I've found on this site, I think I will need a new piston(oversized), ring, head gasket, torque wrench, and have the cylinder honed/rebored/resleeved(not sure of these terms, but basically I'm assuming it needs to be reamed to allow the larger piston. Do I have to remove the entire powerhead or can I just remove the crankcase? Is this job something a person with average intelligence can do or do I need to have some mechanical background/knowledge to tackle such a project?
