That's very cool that it's running well again. The learning curve is pretty steep but once you get it down these things can be dead nuts reliable. Do you have a tach and know what it's turning? I ended up with a Seadoo one off eBay and was able to wire it in without too much fuss.

Awesome, man! Glad you got it running and it performed well. It's a rewarding feeling, for sure.

Few updates, I need to take more pics soon, but heres where I'm at:
I've been running this boat everywhere. I got one pretty good sized dent on the bottom from running some rapids. This boat will do about 2.5" of water.

Me and my girlfriend topped out at 38.6 MPH on some glass, usually run around 28 just cruising for better mpg and smooth ride. I'm sure it could make it to 40 but 28 is fine for me.

I have some issues cavitating when the boat is loaded down too much (4 people and rough water), at about 15 mph. I'm going to try a scooped intake grate, thinking that the pump is running out of water to push at low speeds. I know I could prop down one more if I wanted to be loaded down a lot but I'm gonna try to retain my top speed as it feels like theres plenty of torque on the low end.

I hope the new intake grate doesn't suck up too much junk but I'll test it out.

You can't run heavy loaded up front or you'll have that problem. Get everyone towards the rear and it'll be OK, but not a screamer. You'll also have to ease into the throttle so you don't cavitate.

When I run three up I have the extra passenger sit next to me and the kid up front.

I'm using a Solas 'top loader' grate & haven't had any problems other sucking up junk, except when I run aground!

Your boat's performance sounds much like mine. Fun they are!

I used to run a top loader grate on mine, and it definitely helped with cavitation.
Unfortunately, the open design of the top loader grate also allowed too much debris, weeds, etc to pass through and foul the impeller, so, I had to do away with that intake, and fabricated a weedless type.

Good tip! Thanks, I'll try that next time.

I'll see how the top loader grate performs, if it's not great I might be able to weld a couple of vertical flat bars in it with my tig I was thinking.

Last time I took the boat out I went to the feather river. man is is LOW LOW LOW this year.. I was able to run in just a couple inches of water at some points, but it was getting scary with stumps and shallows, so I was running at 1/2-3/4 throttle (low 30's downstream) at 3/4 throttle it would run great for about 15 seconds then bog down for 5, then run great for 20 seconds and bog down for like 5-10. When I went full throttle it ran fine... but was scary fast (over 40) Could have been a few things I reckon. When I got home I noticed two things:
Fuel filter was clogged up with soot
clamp on my waterbox was barely even on (Not tightened)

I'm thinking maybe the overload of exhaust in the engine compartment was not allowing the intake enough clean air to run properly, but when I went fast there was enough wind to blow it out, or perhaps the carbs were just getting dirty fuel. I guess I'll find out tomorrow morning whether I fixed it. Salmon season started here in CA yesterday, hitting up the feather river tomorrow, we were the only boat out on Monday because the water was so low, but we caught 6 striper and 2 catfish. Good day after work i'd say.

Also just replaced my solenoid because it wasn't wanting to always click hard. Now the thing starts up like a striped a** ape!

Now you got me thinking about finding a 99 Seadoo and beater Jon to converge. That actually looks like a fun project and more fun boat!
