Jet Pumps / Re: YJ with energizer transom plate or cover
« on: September 10, 2019, 12:38:54 PM »
That is an insert pump, and the hull was designed with the intake already in the hull. I forget the name of the model.

Berkeley E pumps and Panther pumps are similar in design regarding the hull.

Although not impossible to remove, these pumps were epoxied in. (Sea Goin epoxy), and usually don't need to be removed for rebuilding.

Cleaning it up is a matter of silicon removal/repair, and then paint, but you are kind of stuck with what you have, without reengineering the bottom of the boat.

The exhaust tips are probably siliconed in, and might need a little persuasion. (BFH) Sometimes they will cleanup pretty good just by sanding and polishing.

Hope this helps.

I've done a few-

455 to 454,
460 to 454,
And a 460 to 350.

They lined up reasonably well.

The 460 to 350 swap, I had to put the hose on the transom tip, and the snail end, And then bolt the logs to the head. Took a little too finagle it, but went on. I double clamped all the joints. Dish soap is your friend.

Hope this helps.

Engine Mechanical / Electrical / Re: Oil Pan Size
« on: September 04, 2019, 03:03:52 PM »
How's it going new to the forum here. I have a 78 Tahiti with a BBC 454 and a Panther Jet. Was curious how I can know how many quarts my oil pan holds? Has no dipstick as well. Looks pretty deep no numbers or markings that I can find. Boat was bought and owner had not much information about it as it was her husbands. She just knew the motor was rebuilt and had not been out since the rebuild. Boat has a SoCal Speed Shop tag on it. Anyways I'm sure I'll be looking on here for lots of information to get this dialed in. Thanks

I have 2 different bbc pans, one is a chrome stock chevelle pan, 6 qts.

The other is a Dooley pan, I believe, 10 qt capacity, filled to 9 qts, if I remember right.

A good pic of the pan would help.

A couple of things-

Secondaries not opening.

Timing way out.

Tach reading wrong.

Starving for fuel.

Good luck,

« on: August 12, 2019, 10:47:13 AM »
Follow your compression test with a leak down test especially on the cylinder with 25 psi.

Even just compressed air through the spark plug hole should give you an idea of what the problem is. Valves or rings.

Might just need a valve job, fingers crossed.

Not sure if itís just getting stopped at the snail, but no water out the back.  Log is ice cold though so there is water flowing that far...


Sent from my iPhone using SoCal Jet Boats

Sounds like either the hose from the t-stat housing to the snail is blocked, Or the snail itself is plugged up with sand and corrosion.

Easy to diagnose, pull hose at t-stat housing and flush with the hose.

1. Retarded timing WILL make the exhaust hot. Make sure it's right. I'd static time it at 10į.

2. We're you running water at the time?
Those hoses, yes the expensive exhaust hoses are water cooled.

3. Sounds like the engine has a fair share of blow by. The intake seal at the china wall might not ever be sealed.

4. 1300 is quite high even for a big cam. Possibly a vacuum leak leaning it out.

5. How is the cooling system plumbed? Water from the jet, to the logs, out the logs to the water pump block off plate, out the t-stat housing, to the snails. Make sure the cooling hoses aren't smashed or kinked.

All I can do without more pics.

Jet Pumps / Re: Taking on Water at WOT
« on: August 05, 2019, 12:16:07 PM »
That would do it.

Gaskets are easy to come by.

Pretty simple repair.

I made one out of a beer box cover, on a picnic table at the river, with a pocket knife. Lasted 6 or 7 years.

Jet Pumps / Re: New guy, New Boat, Random Jacuzzi questions..(688hp)
« on: August 05, 2019, 12:10:42 PM »

Thank you. I too am a firm believer in the WJ. Had a ton of work done to mine as well.

They do make a stainless wear ring for the WJ. I remember taking mine apart and having to cut the WR out.


Sent from my iPhone using Tapatalk Pro

I'm not a fan of a stainless wear ring and a stainless impeller.

Stainless impeller has the plastic wear ring, and aluminum impeller has the stainless one.

I bet a aluminium wear ring would work for a stainless impeller.

What alternator is it?
Some alternator need a keyed hot to make it charge. Home brewed alternator switch? Likewise, and alternator can kill a battery over extended period of time, maybe a alternator kill/isolator switch?

Just wild ass guesses.

Good luck on that one.

Mine is considerably different.
Maybe a different model, I don't know.
Yours is more typical of a bubble deck.
Shallow entry. Shallow V

Mine might be a mini day cruiser?
Double step deck
Probably a deeper V, too.
With ~500 hp, I gps'd it at 71.8

Only seen one other like mine, here on scjb, for sale a few years back.

Nice looking float, should be good for some hp.

I have the same pump I grease mine every time i go out and grease the u joints every other time. I for got to grease it a couple times and it started slipping a little. Greased it up and every time since it runs like a top. But either way it goes if ya want more performance Tom at jet boat performance has a aggressor kit for them.

Do you grease the bushing in the bowl?

The No Wake Zone / Re: 455 olds cuts out
« on: July 31, 2019, 12:57:15 PM »
Hey when Iím running on my driver side tank it cuts out like its starving for fuel but on the passenger tank it dose not do it nearly as much. This is only under hard throttle. The motor has 68 hours on it new edelbrock cark and i just put new filters and fuel pump on it. It seems to be getting fuel could the timing need to be advance a little or ditch the edelbrock 750 and get a Holley marine carb. One thing I havenít done has flush the tank or run it completely out of fuel and start fresh. And the fuel lines are old

On my dual tank set-up, it was the gas cap not letting in any air, and creating a vacuum. A small hole in the gas cap underside solved that problem. Only one side did that.

Back to back testing, the Holley carb worked better than the eddy carb.
Better acceleration, and fuel economy, as well as idle quality.

Fuel rpm and oil pressure. Do you have a picture of the plates?

Sent from my Pixel 2 using SoCal Jet Boats mobile app

No I don't have any pics.
Just a piece of aluminum plate, bolted in place of the trumpets.

I have a oil pressure gauge, don't know what brand, mechanical. I don't want to run oil to the dash. The other is an amp meter. I swapped in a volt meter.

Jacuzzi's have a plastic wear ring.
If the boat has been started out of the water, once, it needs a new wear ring.

The impellers go from A to D.
The A is similar to Berkeley 2A,
Jac. B to a Berkeley  A, and so on.

The rattle could be three things,
The u-joints are worn out,
The spline yoke is worn out,
Or a stainless impeller has been known to rattle.

There is a stainless option in Jacuzzi impellers. Like finding hens teeth.

At over 500 hp, stainless is preferred. At 688 hp should be required.

It is a mixed flow pump, same as a Berkeley.

It already has the better shaft. Loaders would be a custom piece, as well as a ride plate and shoe.

The bowl and impeller could be changed over to a Berkeley set-up, as there are kits available.

Between the kit, and adding a ride plate and shoe to the WJ, a complete Berkeley pump set-up may be the best bang for your buck. All depends on where you want to go with this set-up, how fast, etc.

Tom @ Jet Boat Performance has the wear rings in stock. Also a plethora of information.

Jack @ MPD was the guru of WJ pumps. I don't know if he still works on pumps.

Hurry Round Hondo, a K (KJ) class 'jet boat', had a big blower motor, running a mostly stock WJ pump, was out racing and winning with the K boats. Until it was outlawed. This was in the early 70's.

And lot can be done with the WJ.
I have 2 of them (not for sale) and wouldn't think of replacing them with Berkeley pumps.

Btw, I also have a 74 Glencoe 19' jet. WJ pump. I'd like to see the rest of it.

Is this process pretty straight forward

Sent from my SM-G975U using SoCal Jet Boats mobile app

I guess it depends on where the motor is.

If it is out of the boat, on a stand, and up side down, it's pretty easy.

In the boat, I wouldn't even try.

What engine?

Check around the intake for cracked epoxy

And start filling up the bilge with the garden hose, see if you can find where it's leaking out.

I have a 73 455 olds what alternator do I need or part number for replacement nobody can seem to figure it out

Probably just a gm alternator.
Being a '73,  It could have a external regulator.

If it's missing, I'd put a internally regulated  gm alternator, available at any parts house.

If enclosed engine, get a marine gm alternator.

42A is standard. Boats don't really need more than that. Unless you have a crazy huge stereo system.

Is there a difference besides appearance id prefer the other style cause of where its mounted

Sent from my SM-G975U using SoCal Jet Boats mobile app

Yes, the other one would work.

It looks like you have a solenoid on the starter too. And the top solenoid gives power to the other solenoid (small gauge wires)

The starter is always hot wired this way.

I use the top (Ford fender) solenoid for the battery cable, and a cable to the starter. The bottom (gm style) solenoid is jumped from the big wire to the s terminal on the starter.

Hope this makes sense.

Iím new have a Sleek craft tunnel hull. The current pump on it now is missing a lot of parts. My question is this , keeping in mind my wife wants a  huge Rooster tail ! Our deal for the boat. Should I just have the 12-j E rebuilt or is a 12-JC more adaptable to adjust for a Rooster. And any suggestions advice on best route to go not racing just would like a nice top speed n large rooster tail. What parts do you guys recommend ? Thank you for your Help . New guy appreciation.

And JE bowl is the same as a JC bowl, and a place diverter will fit either.

And JG bowl will also fit the JE suction housing. And a place diverter will fit too.

The impeller will fit all of the above.

Impeller selection with depend on horsepower available, hull type and weight, and usage.

Speed will be determined by hp, hull type and weight, and rpm available, and wallet size.

Hope that helps
