Lol loved that comment bro . When I run with some of u jet guys they get me out of the hole and get 100-200 feet on me and then I run them down lol . I will run with most guys unless I know the set up lol but if I see a BIG ASS blower then it’s meh it’s cool u less they will run a mile straight then I will . My sled loves chop lol more chop the faster she runs

Now the last piece to my jet boat is a pump rebuild as it’s pretty worn out.


Like having a tournament ski prop on a hotrod flatty. It works, but isn't ideal.

It's like comparing apples to French poodles.

"The power is in the pump"

In certain drag racing classes, jets routinely line up with V-drives, and it's all up to the driver. No clear advantage.
V-drive guys don't like hearing about that.

On the river, in my experience, a few v-drives had their asses handed to them by a (my) ditch pump.
Likewise, I've seen the transom of more than one v-drive. (My junk only gps'd 72 mph)

The one clear advantage is cubic dollars- how fast can you afford to go?

That's all I got.

WJ? Or YJ?

Best bet, is Tom @ Jet Boat Performance.

Or possibly an energizer kit, to run a Berkeley style impeller, and then get a stainless impeller. Again, Jet Boat Performance would be my choice.

Good luck with your search.

Eliminator recently did a 21' Daytona, less engine. I believe Teague did the engine and final rigging. Big blower motor if I remember right.

I couldn't imagine the price tag on that one.

Here on Scjb, there was an ad for a complete tunnel hull, 7 color gel coat, for $9k? It's been a while, prices have probably gone up. This is/was a new hull. Still needs everything else, engine, pump, interior, and  even a trailer.

There is new boats to be had, but you gotta search for them.

Getting ready for the burley Idaho race was checking  my pump out ,the input shaft seemed to move back and fourth about a 1/2 inch and it spins pretty freely the impeller sounds like a tin can noise,  talked to George at ars marine he built the pump  said it might sound like the thrust bearing , pumps only 3 yrs old after a 3000 dollar rebuild real bummed , last year blew 2 motors one my brand new stroker motor broke in the first 20 minutes  had a roller lifter fail ,brand new everything  , took out the block and camshaft  and then scrambled to get my back up motor fixed that had a blown head gasket  then after the swaps lasted until late August  then blew another head gasket now I get to pull the pump and send it back to George  this really sucks , but I'm not quitting!! 😠

I'd pull it apart and see what's going on. Several places have an impeller puller. Hopefully the wear ring isn't welded to the impeller. And the wear ring didn't take out the suction housing. Sounds like the bearing slid up on the shaft?

I want to look up a diagram of the pump before I dig in.  Anyone able to confirm what I have here?  I’ve decided to have the boat painted, wondering if I should tape off the transom pump area or remove it??


Sent from my iPhone using SoCal Jet Boats

It's an insert pump.
That changes a few things.

Golden eagle was one of Jacuzzi's pumps, I just don't remember if it was the insert pump.

If it doesn't leak, mask off and leave the insert in the boat. The insert is "glued" into the hull with something like seagoing epoxy, just like a typical pump intake.

Disassembly will be pretty easy with the engine out. And probably the only way to remove the shaft, as it comes out the front. (Bearing comes out the front)

CP Performance has quite a few videos on disassembly of Berkeley and derivatives. The internals are essentially the same, just a Jacuzzi insert housing. Probably Jacuzzi's bearing on a energizer shaft. possibly Jacuzzi seals too.

I hope this helps

The No Wake Zone / Re: ISO My Late Fathers '72 19' Cheetah Stiletto
« on: December 29, 2019, 06:33:44 PM »
My Fellow River Rats your help is needed! In early '72 My father commissioned  a custom built Cheetah when they were located is Stanton Ca. Originally it was Orangish red with a silver deck and a shit ton of metal flake,a closed bow,closed engine compartment. It had a Olds 455 Rocket spinning a Berk jc with a jetovator,and thru the hull exhaust. Ser up with lefthand steering.  It sat on a single axle Roadrunner trailer. Shortly after my dad brought the boat home,he was transferred up to Sacramento for work. Sometime in the late '70's- early '80's ,my Dad sold the boat due to the gas crunch and it being hard to insure. THE boat was sold in the Sacramento area. Then my my Dad died in '83. It has been my Drwam to find said boat and firepower and restore the Boat in My Fathers Memory..... So if ANYbody out there knows ANYTHING about said boat Please help a Brother out! Would be willing to pay a finders fee...

I, too, have been looking for my pops boat. 74 Eliminator, 18' 460/Berkeley combo. White and green. Sold it in 83, in Hemet, Ca.


I'll probably never find it.
I'm building a boat for me.
On the back, it'll say "Thanks Dad"

Only squirt boat #4 for me. Yeah, it's a sickness. My pops started it back in '77 with that boat. That 7 year old kid still plays with boats. 8)

Good luck with your search.

Find the CF numbers, and go from there.

How would you know when it time to service the pump?  I have the motor out, going to be going back in around 500HP.  Should I address anything on the pump?


Sent from my iPhone using SoCal Jet Boats

It's pretty easy to put a bearing and seals in, if everything else is good.

But it can be a can of worms.

I'd look at the front of the impeller.
And then check the front to rear wear ring clearance.

To change the bearing and seals, the bowl has to come off anyways.


Then check the rear of the impeller, as well as the cut of it. Inspect the bowl bushing and seal too.

Might as well pull the impeller and wear ring and check the radial clearance.

Now you are ready to pull the shaft with the bearing on it.

If everything checks out ok, then press a new bearing on and start reassembly.

Minus the bearing and seals, and a couple of gaskets, it's mostly labor. But will a new mill, it's cheap insurance and peace of mind.

Can't leave anything alone so I decided to install a 555 BBC out of my offshore boat into my jet boat. Should be around 650 to 700HP. I have a 1984 Hallett and am wondering how you access the back side of the stringers?

I have not pulled the carpet back yet but I am hoping that part of the floor can be removed. I have not been able to find anything online on how to install in a boat with a floor. Plenty of examples out there with exposed stringers.

Here is what I got going. Holy shit I found a lot of stuff like flip flops, lighters and money under the motor.

My plan is to buy the semi-custom kit from CPPerformance unless anyone has other suggestions.

On my day cruiser, the floor below the jump seats in the back are just screwed down. About 18" x 30" piece comes out, and the back side of the stringers are accessible.

76 Eliminator day cruiser, 21'

And on the rail kits, JBP has them too, made in house, I believe.

Called Eddie Marine today to inquire about the center riser style manifold, which would definitely solve my problem.  Unfortunately they only make this for SBC and BBC......this is so frustrating!

I know there is a center riser out there for a 460 Ford, I've seen them.

Sounds like the best possible way.

Does anyone know of a jet powered catamaran manufacturer?

Catamaran makes me think of sail boats.

Eliminator Daytona is a tunnel hull, is that what you mean?

There are quite a few tunnel jets made by different manufacturers. 18' to 21' or 22' is pretty popular in jets.

If I'm spending your money, but a new one.

Spray all the aluminum and chrome with wd 40. Helps keep the salt corrosion away, and easy to clean up. (Valve covers, intake, etc.)
Wash the trailer really good, too.

Chrome? Or aluminum?

It looks like a single plane manifold, if it is, and the ports are reasonably close to matching the heads, I'd run it.

If its chrome, is it iron? Not that iron is bad, but it's Damn heavy.

Edelbrock performer is usually a safe bet, edelbrock claims 455 ft lbs of torque with stock heads, and good intake, yours looks like it has an aluminum intake (or its painted silver)

I'm not a Ford guy, so others might know if there is something better for your application, but I've had good results with edelbrock parts.

Mini Jets / Re: 11ft home built mini
« on: October 20, 2019, 10:43:50 PM »
Started life as a 18ft kona. Took 2ft out of the center and 6ft off the length. berkeley jet with place diverter, powered by a gsxr 600. Not sure what that combo will do but we'll see. Plan on keeping the 6spd tranny in play

First, I'm not a motorcycle guy.

Second, the gsxr 600 makes between 90 and 110 hp, @ ~13,000 rpm,  depending on year. These figures are from the interwebs.

For a Berkeley pump, with a "C" cut impeller, (the smallest impeller with a detailed chart, from JBP) requires 92 hp @ 3300 rpm, and 110 hp @ 3500 rpm. This is pump shaft rpm.

With the gsxr transmission, 3rd or 4th gear might achieve 3500 pump shaft rpm, with an engine rpm of 13k rpm.

A "C" cut, as well as a "D" cut impellers are not as efficient as an "A" or "AA" cut impellers.

With trying to compare a mini jet boat to a 18' jet boat, it's difficult at best. Let's try.
My boat, 18', Sbc 350, Berkeley "A" impeller, at 4000 rpm, is roughly 45 mph, ~ 228 hp.
With a "C" cut impeller, 228 hp would be about 4500 rpm. The volume of thrust (water) would be similar. So would the speed. (A @ 4000 vs C @ 4500).

2700 rpm is about the slowest I can keep on plane. Somewhere around 22 mph. With a theoretical C impeller thats about 3000 rpm.

Even if your mini jet boat is half the weight, with a "C" cut impeller, at  3500 pump shaft rpm, 35 mph would be full throttle. Possibly 40, but I doubt it, just a wild azz guess. Remember, to achieve 3500 pump shaft rpm, the gsxr will, WILL, be @ 13,000 rpm.

I would go one of two (or 3) different ways-

Keep the Berkeley, and put in a light engine, with double the hp (Think Subaru flat four? 3100 60° GM V6? Ford 2300 turbo?)

Or keep the gsxr, remove the Berkeley, and use a suitable jet ski pump.

Or use an entire jet ski engine and pump. (The aluminum mini jet boat guys have been doing this for years)

I hope this helps.
Others might have more insight than I do.

« on: October 17, 2019, 03:09:48 AM »
New to jet boating loving it, I have 468 with logs and snails thinking over transom headers would be rad. I'm curious about how you preheat the water without the water jacket in the logs and would I still verry the water flow with the valve on the pump?

The water is no longer preheated.

Water from the pump is slowed down, using the gate valve at the pump, to maintain engine temperature. 130° underway is plenty, and running 155° in the no wake zone is fine.

The water is Tee'd off to keep the headers cooled. 30 hp is typical, even more on performance builds.
