I'm to sell my boat which has a 90HP Johnson V4 on it....
One of the possible buyers took the spark plugs off and tested the
combustion of each of the cylinders... one of them failed badly....
Is it worth fixing these things???I don't want to fix it myself cause I
might not get the money back when I sell it.... when a motor of this age
(about 1985) and has these problems i igt worth fixing??



You have to remove the cylinder head to see how bad the damage is. If the
cylinder is not deeply scored, it can be bored oversize and a new piston
fitted.

Being a 21 year old motor, it probably would not be economically feasible to
repair it, unless you planned on keeping it for a few more years. If it is a
salt water motor, then it is not worth fixing.
