Great find

Go with the biggest impeller you can, big girl needs a big wheel.

Make sure there's a gate valve on the incoming water line. Adjust as necessary, 140 while cruising is plenty. (helps keep pressure/ volume in check)

The Jet-O-Vator steers wonky, and virtually impossible to get parts for. Upgrade to a Place Diverter. Standard equipment on Berks from the mid 80's on. Go hydraulic if you can $wing it.
Tom or Josh at JBP would be my first phone call.

 78th annual thanksgiving regatta at the Blue Water Casino
Friday Nov 29th and Saturday Nov 30th

A thanksgiving tradition.

What it sounds like happened, he made a pass, then went over a wakeboard boat wake, made a U-turn, and went over the wake again, and when he lifted, the blower motor stalled while at a pretty good speed, and hooked a bit to the right, and that's the aftermath. There's a video around that shows hitting the dock and the brick wall. Apparently, both occupants had some bumps and bruises, but walked away.

I had a pair like that for the jet skis, on an open trailer. Never had a problem.
I'd even use them for the boat, when gas was too far away, like camping on Lake Mohave.
I didn't think they were tough enough for the Jeep, hanging off the back. I had steel cans for that

I've got nuthin on a tunnel ram.
Leaking intake gasket on the lean side?
Which way are they mounted?
Freight trained or sideways?

That thing sounds super rowdy

Yes, yes it does.

Just finishing up my SBC fishin bote mota, Ill be lucky to have HALF the HP and torques of your mill.

Well done.

I keep it under 235 degrees at .050" on a small block Chevy with logs and snails, with no issues.
Sbf and center riser exhaust I'd imagine? Your numbers look good for that. I'd run it.

GS Marine in Corona does pumps.
Jacuzzi? I don't know.

MPD in Costa Mesa would be my choice.

Or get a kit from Tom at Jet Boat Performance, and do it yourself.

That time of year again
Merry Christmas

I have a 76 Eliminator Day cruiser.
A full 4 stringer hull.
Rides like a Cadillac.
Fast? Not so much. Even with 500 HP BBC, it tops out at 57 mph.
I've been thru some serious chop in Lake Mead, and handled it great for a squirt boat.
I've been on the big 3, Mead, Mohave and Havasu, but mostly on the Bullhead Riviera.

Several manufacturers had similar 4 stringer day cruiser hulls. These hills are 40+ years old, and each hull needs to be inspected for stringer and transom rot and delamination.
Spectra, Howard, Campbell, Hallett and many others are still out there. Even a few lesser known names. I'd opt out of the Olds powered boats, FYI.

Good luck with the search.

It sounds like A impeller territory.
I'd first check the wear ring to skirt clearance.
Some can be measured through the clean out inspection hole.
If it's waaay out, then pull the pump apart, inspect the impeller, and you can also see what size the impeller is.
Feeler gauges for checking the gap.
My last one was .050 per side, or .100 total.
Ideally, .012 per side o r.025 total is factory spec.
