Back to the grind stone.

Decided to switch it up and work on the pump today. I followed @Rdrttoy method to install the bearings. Worked very well. sometimes heat wasn't even needed, just freezing. Honestly this was quite enjoyable to do (my first Yamaha pump rebuild) unlike a few Kawasaki pumps I've done. The bearings seem Un-damaged after the install. I have a cold fusion pump alignment tool, so hopefully I'll never need to replace the bearings ever again!

Pump set up-
9/15 hooker
New JM wear ring
Solas 144 mag
Stubby cone
62t reduction nozzle
Xmetal(I think) trim
62t cone

Lots of goodies for the build later on! Thanks @JetManiac for having almost basically I needed. Also @yamanube for some extra bling.

Reinforced the hood with biax, it's strong! Still seems pretty light too especially compared to before. Just gotta work the hood a little more(still need to figure out how I want to vent it) and a little more hull prep and this will be ready for paint!

Dropped my hull off for final prepping and paint. So I'm just playing with my other toys right now. Really cleaned up this old factory pipe waterbox and the chamber. Kinda layed out the motor and such and it's gonna look pretty nice in the hull! Any tips on cleaning up the gas tank?

All I can say is WOWEE! I think I might need some spaceship fuel for this thing cuz all it wants to do is take off! This feels like a whole new hull(of course all I've ever ridden was a 440 and a waterlogged superjet). I rotated over half way on my first jump, and I wasn't even trying! Anything past quarter throttle and it just hooks up and jumps out of the water.

Right now I'm just running an eyeball tune with the carb pretty rich. I could only imagine the potential if a pro could dial in my pipe and carb. Which I would pay good money for someone to do for me in the Midwest!!!

As for backflipping, i have minimal experience. As I only have done a couple on a trampoline before almost breaking my neck lmao. I did a few backflops (more than half way) on my first day out on it, but I was focusing more on making sure that I wasn't sinking, overheating, etc etc. I'm sure after getting used to the new hull and more backflop attempts, a backflip should be completed in my future.


Only negative-

Porpoising is pretty bad, maybe I need to ride it more to get used to it. It's hard to take over 25mph. I could get another ride plate and cut it 1" less. I'm glad I didn't cut past 5" I'm only 160lbs and it likes to ride pretty nose high. A shorter hand pole would help too I bet.

I want to give a thanks to all you XH20 members who hooked me up with awesome deals for parts through the forums as I was building my hull!!!!! I was building on a budget and almost every part I got was used from this site, which added up and saved me quite a bit of money.

Still more to come

It will stop riding nose high once you get more time in the tray, once you get used to it, a stock superjet will feel like a tank.

I've been using a full length SN ride plate and it's perfect. I thought I would cut it shorter, but it rides nice with it, just looks a little goofy bc it doesn't line up with the the hull lines
