1985 150HP Yamaha Service & Repair
Compression is Good - Bore is Good
Replace the Thermo's, Head and Cover Gaskets.
"The 150 is a tough old beast and if in a good condition they will continue being usable for a long time" said Bruce at Can Do Marine.
Most non commercial 150's would have under 500 hours. They drink fuel fast compared to modern 2 stroke's, but the cost of fuel is not always a big factor, you can't always justify spending thousands on a new motor when your only able to get out twice a year.
Bruce at Can Do Marine advises that you keep your boat engine in a good condition. If you've got a 150HP Yamaha it may be time to service and change the head and cover gaskets.
This motor had a stuck partially opened thermo and a lot of corrosion on the starboard head and cover.
Bruce at Can Do Marine will Clean, Repaint both heads and Continue with the Service.
