Anyone know if a 3 cylinder Yamaha 90 hp can be re lined with a cylinder tube ?

Talk to your local machine shop and see what they say.

Is your cylinder messed up to the point that it can't just be bored oversize and new piston? I believe the liners are cast in place rather than pressed in, but your Yamaha dealer might give some thoughts on this. Good luck!

check with a MARINE machinist, even cast in liners can be bored and resleeved.
Ron's marine and equipment in portsmouth VA does it all the time.
