A buddy of mine bought a new Dorsett boat from Thurston. On the second year the exhaust valves tulip on the 5.7. Something about the boat was made in Canada and Dorsett is responsible for the engine, call the company? Sounds like Thurston is giving my buddy the up yours!

A call to Mercury and my buddy was told to see a certified Mercruiser shop. Pretty easy to find. The boat was towed to Glendale and Dave Motorboat took care of it. Mercury practically paid for a whole new top end no questions asked. We still wonder how valves can get tulip. Most mechanics says more than likely the valves were defective. In rare cases the gas mixture may have been too lean and at WOT the valves can over heat.

I would call Mercury and let them determine warranty claims. Not the dealer.

BTW, the towing was paid by the boat insurance. This is a supplement you can get for peanuts. You can also get an insurance supplement that will pay for engine repairs. Call the insurance company!
