Excellent points! Thank you for the reply. I ride exclusively in fresh water, so I think I'd be fine. I could always paint the aluminum before I reglass my FX1 tray and put new foam in there. I was also wondering about the RN Superjet exhaust tube. It appears to be aluminum, but I wasn't sure.

There's a noticeable difference with weight. The FX1 pipe is heavier than an aluminum super jet pipe.

For what it's worth, when I set pump shoes I install the pump w/drive shaft , aligned w/ cold fusion tool to the bulkhead. I have the shoe just held with a bunch a bubble wrap around the driveshaft so I can flip hull over without shoe banging around. With pump and shaft aligned to bulkhead perfectly I then shim/center shoe to pump. The shoe maybe hanging out of the bottom of the tunnel, it may have massive gaps between shoe and tunnel but I always go for seal placement/squeeze out as priority one. That way your able to open id of shoe evenly, not trying to get all the increased diameter from one area. Then I shim behind shoe, build gaps up with epoxy and grind or belt sand anything hanging down. In the pics on this install you can see how much I had to grind off bottom of shoe after aligning to perfectly aligned pump.View attachment 419080View attachment 419081View attachment 419082

Where did you get these pump shims from?

I think the main difference is that the stainless would be ultimate corrosion resistance, whereas the aluminum can corrode in the right conditions. Obviously the stainless would weigh a bit more also. Bust almost all the aftermarket hulls use an aluminum tube as well as the RN Superjet. If your tray is sealed properly, I don't think the aluminum tube will ever be a concern. Only if water, especially salt water is allowed to enter the tray and sit around and on the aluminum would it start to corrode. I believe that the oily coating inside the exhaust tube would pretty much make it impervious to any corrosion. I guess time will tell!

I defoamed a RN with the stock aluminum exhaust tube. It was waterlogged and over time the corroded pin holes in the pipe. The waterlines were starting to do the same. Ever since then I spring for good stainless.

How old was the ski when you deformed it

About 17 years young. Who knows when it actually failed, judging from the oil on the foam, it was like that for some time. It was salt water use.

@vcolf l think your right when you say it had been soaking for a long time. And no where to go either. Most of these rebuilds are using the home insulation and drains in the bottom of the tray.So the exposure is a lot less. Also,if the aluminum is treated with a corrosion “resistant” coating, l believe the aluminum will last a lot longer.

I can’t believe this thread is taking so long haaaaaa. Been really busy with all sorts of stuff, life comes at you fast and sometimes jet skis have to take a back seat. But I have finally made some progress. I swear this will be done over this winter, I can’t take it anymore hahah. I removed the stock hood liner from the hood, which was a major PITA! I got all the glue sanded out and made some modifications to the hood. I will explain those more during assembly but once I got everything the way I wanted, I made a hood liner from a roadside sign, and then taped it up with packing tape and laid up a glass hood liner.

After it cured I pulled it out, not too bad.

Then trimmed it out and made it smooth…

It fits extremely well!

Debating on wether or not to make a mold of this piece before I punch my breather holes… seems like it could be a handy piece for any FX-1 builders… I know I would have liked to have this already made haha.

You should most definitely make a mold of that! I learned to fiberglass on my SN hood liner and it did not go well!!! Nice work!
