Broken crankshaft

**dtrumbower** · 08-03-2020, 05:04 PM

Not my engine but looking to purchase boat. How does the crankshaft break this way? What is the ball park to rebuild the engine? I do live near Fond Du Lac, WI, and I know there are few people that do this that are Mercury employees too.

Thanks

That is a 13# cast iron flywheel that DONT FLEX.

gonna need a stator and full powered gasket kit and motels well piston rings along with the crank. Lookn at $100 if you do it all yourself.

I see brand new cranks are $2K. Might be better off getting a rebuilt powerhead or upgrading to a newer engine.

Someone tried pretty hard to do that.
