1988 Johnson 90 hp outboard

[du]

This motor has gotten hot and scored the 2 right <br />side cylinder walls. Shall I fix it or get another motor? I know power head are probably <br />available. Don't want to spend alot of money<br />tops $4000.

Welcome!!<br /><br />You can certainly get going for less than 4K. If the motor was performing well before it overheated I'd fix that one.<br /><br />Are you sure it overheated or did it break the rings?

Hi: I have found that the pistons or at least<br />three of them have slap or are lose in the cylinder walls. Bad! The motor would have to have a complete overhaul. I now have purchased a used 60 HP two stroke Tahatsu and a 6 HP Nissan<br />four stroke kiker motors. New 70 to 90 HP two<br />or four stroke motors are out of this world in price. Will do with the two I got for $3800.<br />Thank for the reply.

2 stroke pistons are supposed to be loose.
