Default Mercury wont warranty 2020 400HP / Invincible 40' quads

I have a 2020 40' invincible with quad 400s with 100 hours. An engine went out while headed to the beach this past weekend. We took boat to mechanic and they found water in 6 cyclinders. Mercury will not warranty. All other engines were dry with no signs of water intrusion. Can not figure out how water got into that engine so severely. Anyone have any ideas?

Boat was just serviced at 100 hours the day before.

What was the reasoning for declining warranty coverage ?

They said water getting into the cylinders is not covered under warranty.

Does not sound correct, defective part can allow water into engine. So all you were told is they do not cover water in engine? no details as how they assumed the water got into the engine?

Its only been a week, have you worked it up the chain? Talked to managers and your dealer etc? Did the mechanic look for a cause of the water or just chalk it up to "water intrusion"? It think if he can find a head gasket that failed etc then they would warranty it. If there is no mechanical failure then it likely will be outside of warranty.

Did that engine happen to go into reverse for some reason while the boat was going forward?

Describe in detail the circumstances where the engine problem showed up. In detail.

The mechanic can not find signs of how the water got into the engine, so they can not prove that it was another faulty part. They say its possible that the operator(me) quick stopped the boat and water flowed back into the engine. I have run boats hard for 20 years, this was not one of those times with my kids and family on the boat. Also all other engines were bone dry with not even as much as salt spray on them.

Do you remember chopping the throttles quickly at anytime that day and possibly going into reverse a bit when doing so? Maybe that's what they suspect if there is no other evidence of failure. I would ask them exactly why they are denying coverage and how they reached the conclusion. Hope you get it sorted out.

I turned and then lost the engine.

Whats also interesting is the engine has a faulty oil cooler that mechanic is waiting to get brought in. It is not leaking water that they can see. It does leak small amounts of oil.

"Water in the cylinders" is just the end result, you need to find out the underlying cause. If e.g. it turns out to be a cracked block you would have a very strong case for warranty repair.

However I find having water in all cylinders the day after a 100-hour service to be very suspicious. There is a definite possibility the mechanic screwed up in some way. If that's the situation the warranty won't be helpful, but you'll have a claim against the marina which did the service.

Thank you guys for the reply. Any further investigation of the engine would need to be covered under my costs because the mechanic has spent the alotted time that mercury allows a mechanic to spend trying to diagnose it. Bad deal if you ask me.

Did mechanic break engine apart investigating, or did they once over it without taking anything apart?

They seemed to have gone over the engine pretty well. I talked to them over a 3 day period and I use them a bunch. They are baffled. Mercury also only allows them so much time. Any further investigation would be on me.

if you trust them then would tell them to figure out how the water got into it. If not have someone else look at it. Consider it a wager, that could save you thousands, if can not find it, then out a few 100. Good odds.

Find a new dealer. For all those talking about chopping throttle to reverse, he’s got 2 controls. Would happen to other engine on that side as well. Pretty shitty of mercury.

Sounds like mechanic messed up and they are trying to cover their butts.
