Pulling out your pump and freshing it up isn't that difficult. Once the impeller is off, and it's in good shape, just a matter of a wear ring clearances, and put it back together. Same if you need a new impeller. It's not rocket science. (Just jet boat science) youtube has a very indepth videos, from cp performance.

I've done half a dozen pumps over the years.

That's a Rockwell unit, bolts to the crank using 4 of the flywheel/flexplate bolt holes. No pto adapter needed.
Olds, Ford and Chevy patterns available, what this one is, I don't know, but I have an Olds and Chevy ones that Ill compare, but it's at the river.. and I'm not til Saturday.

That's a Place Diverter, it steers first and roosts second.
A Jet-O-Vater, Berkeley trademark, roosts first and steers second.
You have the better product.

It looks like there is a quarter of an inch more up travel, maybe more.
The handle has some adjustment as well as the cable mount on the Diverter.
The rudder only really works in the no wake zone, anything faster, and it scrubs speed. 5 squirt bötēs, not one rudder.

Hope this helps

Happy holidays

Update 11/18/20: I just spoke with La Paz County Park Director and we are preliminarily a go for the Absolute Speed & Marine 74th Annual Thanksgiving Regatta presented by Nick Rose Insurance. I have a final conference call tomorrow (Thursday, November 19, at 9:00 am) to iron out final details. Most likely the following: All teams will get temperature check when they come into the park or pit …

I'll be there.

I'd check to see if the intake is still epoxied into the hull.

The intake fin is not that big of a deal, as long as it doesn't leak, however, that boat took a pretty hard hit to do that.

That Jacuzzi YJ pump is pretty reliable, and good for a heavy boat, but don't expect much top speed out of it, either. Keep an eye on the rpms, stock olds don't like much more than 4500 rpm. If you get more than that, you probably need a wear ring.

Always loved the sleekcrafts.

Sounds great.

Will you be at the Thanksgiving regatta?

Dan'l

Planning on the Thanksgiving races? I'll be there, probably just Saturday.

You are always invited...
River gets low... lake is always up

Blow me...
Boating season ends Dec. 31.
And starts Jan. 1.
Usually last time out is Thanksgiving Friday, water level permitting.
First weekend in March weather permitting. Fishing (eek!!) Thru the snowbird season.

Oldest granddaughter will be ready to ski next season.

Boat still looks great!!!

I always think, "why are the headers upside down on the dyno?"

Sounds awesome, any numbers to report?

Whos running EFI with open cooling?

Sent from my SM-G950U using SoCal Jet Boats mobile app

Most newer Mercruisers are efi, and open cooling, so it's pretty common.

Lower water temperatures are proven to make horsepower. 160 should be the upper limit, hard water and all.

That's all I got.

Nothing wrong with a JC pump.
Its just not a split bowl.
You already have a diverter on it.
G bowl will fit right on. (Split bowl)
Intakes are virtually identical to the newer versions.
Same with suction housing.
Impeller to wear ring clearances will make a huge difference.
Loaders are available.
My JC pump has both a loader and a ride plate and shoe. Diverter too.

Yes there is better set-ups, but you have a solid foundation.
