2020 Supra SL 550 Roush Engine needs to be replaced not under warranty
Anyone every heard of a 1 year old engine needing to be replaced and not covered under warranty by Indmar. We have put in premium gas and mostly non ethanol every time. Went to Lake Powell and bought fuel that they are saying had water in it and destroyed the engine. Now being told a new motor installed is anywhere from $25,000 - $40,000. Any advise - anyone had water get into their engine from faulty equipment and not just a bad batch of gas? Had another boat with us that filled up at the same time same product but not a super charged ultra sensitive motor. Had one misfire and no other warning and 12 boat hours later had a smoking boat and destroyed motor. Not a happy boater at this point!!
Anyone else had problems with the Indmar super charged motor?? All they are considering is bad fuel and not looking into faulty parts?

I would take that report to your insurance company.
If someone poured sugar in your auto gas tank, insurance would cover it.
Water is an equally foreign substance.
I still think water in fuel should put engine in limp mode and keep it there. Indmar should cover it no question.
Very familiar with forced induction engines and detonation with bad fuel is typically mitigated with knock sensors that pull timing until knocking stops and if knocking continues it goes in limp mode:
I would argue that Indmar didn’t have the correct amount of timing pulled for subpar fuel.

Good luck sorting it out.
So you have the Indmar warranty when you bought the boat? Sounds like a new purchase, but I know people turning out their 2021s already.
I’m betting they will take care of you.

As for the 550 motor, I have friends with that in the SA and SE models. They have no issues.
On social media, I think I’ve read about 1 or 2 with some type of ‘failure’. It’s not many.
If anything, there are probably more error codes I hear about. The mechanics I talk to compare it to the older 496 motors that were a “little more finicky” vs the std motor option.
