Hydrolocked after winter storage

BroadHopper · 08-16-2017, 07:30 AM

My marina, will take care of anything that they screwed up. It's on the winter storage contract. Most marinas have insurance and they cover it. A few folks had cracked blocks etc sue to improper storage. The marina took care of it and replaced the block with a remanufactured block.

As far as hydrolock, usually happens at idle when the water is forced back up into the exhaust due to a wave. I just remove the plugs, churn the motor over a few times to remove the water, spray a generous amount of MMO in the cylinders, churn it over a few more times, and replace the plugs. You may need starter fluid to start the engine as the MMO is heavy.

How does the marina explain the problem?
This is clearly their fault and I would have your lawyer send them a friendly request to make it right if they don't step up on their own.

Take a closer look at his picture guys. There is a rust line across both pistons that indicates to me that standing water was in the combustion area for a while. Looks like poor winterization or water got into the engine somehow creating the aforementioned hydrolock.

I'd like to see the entire photo with all 4 holes completely visible. The current photo with a little more than half of 2 cylinders doesn't tell the whole story.
