I just recently got the opertunity to by this boat that needs minimal work on the sub floor<br />with a trailer, from my brothers ex wives husband.<br />he said it ran great 2 yrs ago when he got it and that it was running on only three cyl. due to a bad coil?. could this be right and what other things should I check? He only wants 400 for all.<br />is it a good deal?<br /><br />p.s. the motor is a 1984

Howdy, Tony.<br /><br />If it is only down 1 cylinder, and that one has no spark the coil is a prime suspect.<br /><br />Get a good battery on it and do a compression check. While you have the plugs out see if you can get spark on each cylinder.<br /><br />Each cylinder should compress over 100psi, and the four should all be withing 15psi of each other. <br /><br />If you are missing spark on one, switch the coil with a good cylinder and see if the problem moves with the coil.<br /><br />Buy it? You have to decide that for yourself. There is no such thing as minimal work where rot is involved.<br /><br />Good luck.
