2008 200 hp Merc inboard - hydrolock

by Greg
(Oakdale, MN)

While boat is self draining after being removed from the water, some water gets into manifold and lower cylinders causing hydo-lock.

To get the motor to start again, I have had to siphon out the water, manually turn the flywheel backwards, tilt the boat trailer up to drain water out. Has anyone had this happen? Is there a way to fix the problem?
Thanks for any advise, Greg
