    Good point Frank. Will dig around. Checked all cooling passages, tubes etc with compressed air and they all flowed well.
    I’m also thinking gasket on exhaust housing under powerhead was shot allowing the hot exhaust gas to move to the front of the housing instead of dumping the exhaust out the back of housing under the pistons?
