480 CE Head Replacement

I have finally decided to get the monkey off my back and replace the cylinder heads on my 480 CE’s. We have a 2005 SeaRay 420 Sundancer, and are the second owners of the boat. I know it was overloaded before we owned it, and I ran it overloaded for a year or so prior to finding Tony’s information here.

I attached an estimate. I have been so paranoid about this issue that I have been reluctant to use the boat, especially since I learned of another 480 CE dropping the valve across the bay.

I have already taken 2 inches out of the props and right now I am at the 450 burn numbers Tony has recommended. I have a laminated chart with the burn numbers on it and depending on how clean the bottom is or how loaded the boat is, I just run the boat at a speed/RPM to stay under the burns according to the chart. New props with another 1/2 inch to inch removed are next after I make sure this repair is complete.

As we get the project moving, I will follow up with some pics hopefully and updates. I see this as a reset on the life of these engines.

Thank you to Tony and his amazing team at Seaboard, I have purchased several items over the years, and their service and advice is un-paralleled.

I hope everyone can learn as we take on this adventure together. (edit after talking with Tony, I attached the complete estimate)

Thanks!

Matt
