I have a 1988 Yamaha 115. It's old, but it doesn't have a lot of hours on it. Last year, It ran hot and shut off. I have discovered that there was no actual piston damage, but in one cylinder there was a cracked thermostat cover and water leaked badly. On that cylinder, the piston expanded and now that it has cooled down, the rings are compressed and stuck. I've been told that there are products that you can put in the gas or spray and let sit in the cylinder that will loosen up the rings.
Again, the piston is in tact and there is no visible scoring of the cylinder.
Any ideas on this would be greatly appreciated. I certainly don't want to have to dismantle this block to replace the rings.
Thanks,
