Is it spraying water around the nozzle?  If not, I wouldn't worry about it.

On the other hand, the old style nozzle with the grappling hook style reverse shoot, dragging through the water, would be scrubbing off your speed.

See how the Place Diverter nozzle design has really been cleaned up to reduce drag (https://www.placediverter.com/home/product/place-diverter-nozzle).

Thanks Flusher,

There is quite a difference with the Place nozzle. There is some spray, but its not bad. I am fighting a bad porpoise just after I get up on plane so I have been looking hard at a Place Diverter.

It's laid up for the winter now for some floor repairs and other stuff.

Thanks again,
Bill

Found the info, my nozzle is part # L-2847, there is another part # L-4405 that has the O ring that seals to the bowl.

Mine isn't worn bad at all, the boat has low hours. How much speed could I be leaving on the table?

Jet Pumps / Berkeley Nozzle O RIng

Hi guys,

I have my pump apart fixing the blown out bowl gasket and I noticed that the nozzle does not have an O ring where it goes into the bowl. It is a 1972 Berkeley 12JC-A, was the O ring an added feature later in production?

Update:

Got the transom cover and the bowl off. The gasket was in many pieces lol!! I guess the O ring could hold the water when sitting and at low RPM but would let it pass once the pressure got higher.

I have the parts on order from CP Perf.

One question, my nozzle doesn't have an O ring where it goes into the bowl. Its a 1972 so is this something that came along later?

Thanks for the help guys!!

Thanks for the replies guys!

I am planning on new gauges this winter but I'm going to grab a new tach right away. I just got a new set of plugs for it, it had Champions set at .060"!! Seemed a bit big, I'll run the new ones at .035". I will check for correct TDC on balancer and recheck timing too.

I'll update when I can!

Engine Mechanical / Electrical / 455 Low RPM
« on: August 16, 2019, 09:47:58 AM »
Hey folks,

Our '72 Sea Ray has a 455 with a Berkeley 12JC-A and it tops out at only 3,600 rpm.

We purchased the boat from an estate sale so we don't know too much about it. The engine was built in the mid 90's. It runs smooth and sounds good. No missing or pings. The pump is clear of any debris. It has a Quadrajet that is opening fully, compression test is good. MSD 6AL with a 5000 chip in it.

Any thoughts on where my HP went????

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.

Nice!! Love the picnic table repairs lol!!

Well, I got the water figured out. At anything over 2000 rpm, the water flows in pretty good past the bowl gasket on the starboard side. I checked the bolts and they didn't tighten much so I guess I'm gonna have to pull it apart.

Good day folks, new guy here from Canada.

I have recently picked up a 1972 Sea Ray SRV 190 with a 455 / 12JC - A.

When running around at low rpm the bilge stays dry but after a higher speed run, it has a fair bit of water in the hull. It takes a minute or two for the pump to get rid of it.

Would this be the bowl gasket leaking? Everything else under pressure in the jet is outside the hull.

Thanks in advance for any suggestions!!

Bill
