Chrisb Posted August 31, 2019 Report Share Posted August 31, 2019 Boat is loaded onto the trailer for the season. Water cooling system leaking at the head. Motor overheats of run at less than 3000 RPM. Need to pull the power head off a 60 Mariner and hopefully it is only the gasket and a not cracked metal housing.

Steve_Guelph Posted August 31, 2019 Report Share Posted August 31, 2019 That sucks. Hopefully it’s only a gasket. Link to comment Share on other sites More sharing options...
Chrisb Posted September 1, 2019 Author Report Share Posted September 1, 2019 Engine runs great otherwise. Marina says 6-7 hour job at $125 per. I think I can do it myself with some friends. Just need to order a lifting eye ring to screw into the flywheel. Link to comment Share on other sites More sharing options...

Good luck with that Chris , I hope it's just the gasket . It would be nice to fix it yourself and save a lot of money (& tax) . T's me off we pay tax on labour ...that pays the mechanics wage . Maybe get some google help with this job.... Link to comment Share on other sites More sharing options...
Chrisb Posted September 1, 2019 Author Report Share Posted September 1, 2019 I have the clymer manual. Biggest problem is going to be lifting the head. Info I have says it weighs 210 pounds. I think one of my buds has an engine lift can get use of. Link to comment Share on other sites More sharing options...

Chrisb Posted September 18, 2019 Author Report Share Posted September 18, 2019 So it turns out I do not need the power head pulled. When they installed the water pump seal kit at the marina they used a new seal between the pump and the riser tube. It is a 3 inch tube with a seal inside. The issue is the riser tube is smaller diameter than the water pump output. The old seal was two different diameters. The new seal was the same at both ends. So with the new one no seal at the tube and much of the water was not being pushed up into the engine. Good thing I made them save all the old parts. I was able to find the issue myself. I could not believe the power head needed to be pulled. Link to comment Share on other sites More sharing options...
