Eddie, See the link posted below. Would the valve spring coating add to increasing the upper end service intervals? Is the valve springs the primary reason for upper end service?

FYI----I have used Dan Swain for many years and two-stroke motor builds. Simply the best of the best.
Also, in post #4----one of the pics showing the rear motor view, a small filter is shown with what looks like (2) solenoids. What is that device?

Very nice work and thanks so much for sharing your talents and creativity to all. Richard

Still here. I must have missed the post you made a few days ago. Sorry, but I would rather not say what the comp. ratio is. Nothing personal.....I hope you understand. Just got a call about 10 min ago that the tailpipes are ready. I'll get them next week and get it fired up. As soon as it warms up a little I'm going to the water.

Rotax,
Never heard of the coating you're talking about. I will be sure to check it out. It's not only the valvesprings, but the lifters and camshaft. The cam starts to get grooves in it because of the spring pressures. The lifters start to get worn out from all the spring pressure as well.
What you see on the rear of the engine is the IAC. (Idle air controller) I run 2 of them since the boat has so much prop and gear, it puts a tremendous load on the engine when you put it in gear. 2 IAC's half to work half as hard as 1. Basically, they respond much faster and don't have to open as much. Thanks for the heads up on the coating and the compliments.

Thanks Jo. I'm still waiting to put one in a Pantera.

Eddie, Please take the time and call Dan. He has been in the specialized coating business for a long time. You will hopefully find the call educational.

Here a few updated pics. I fired off one of the engines today. I'll fire the other tomorrow and if everything is good......to the lake. Had to make a driveshaft guard. The boat had guards at the rear, but none on the rear of the front engine. I could just see the u joints breaking and the driveshaft sticking in the mud on the bottom of the lake......just after it went out the bottom of the boat. I also had to make supports for the long tailpipes. They are so heavy that I was concerned about them bouncing around and cracking the headers.
Hardin Marine did an absolutely fantastic job building the tails. I can not say enough good things about them and the pipes. They nailed everyone of the tails on the money. All 4 fit perfectly.
Here are a few shots. Enjoy, Eddie.

Great work, Eddie. Those tail supports are beefy!

They need to be. Those long tails probably weigh 85-90 lbs each. I was worried that the bouncing would crack the headers or the tails.
