Hi Doc, footer again... I pulled the cylinder head on my '79 200 and right away the head was not sealed well... When I got it off, the top 1/8th of the piston looked like it was shot peened into the combustion chamber and remaining portion of the piston is down in the cylinder sleeve. Upon further investigation I hand turned the engine over and all pistons are solidly set in their cylinders and they appear to be in very good condition, and very responsive on the crank. However #2 looks to have about a 1/4 inch of slack or back lash in the crank, so I think that the conrod has loosened off or cracked and therefore the extra travel has allowed it to come in contact with the head. Note that the motor still operated and made no "knocking" when I disassembled the heads. Compression was obviously way down on #2 but all others were around 145-148 psi, is this still decent? <br />Here's my question Doc if all other pistons are OK and the crank is not too damaged (might need to be turned anyway) do you think it possible for me to replace the #2 piston, conrod and hone the cylinder sleeve? The sleeve has only one small score in it maybe and inch long and 0.005" deep. I was planning to sell this boat in the fall/spring and upgrade. I would disclose this obviously to a potential buyer, but would like to not have to spend a couple of thousand, if I can get the piston and crank figured out. What do you think? Is this tabboo? I usually like to do things the right way, but in this case if I completely rebuild the engine I should probably keep the boat as I don't think I'll get the money back out of it. Also, are the heads the same as a 150 HP Black Max for that era, circa 1979? I may need a new head? Any thoughts would be greatly appreciated, thank you!<br /><br />FOOTER
