Jet Pumps / Re: Question About Intake 76 Executive
« Last post by mash on it on October 28, 2020, 04:46:54 PM »
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.

I don't see why it wouldn't work, but I'd ditch the water pump for a plate.
What hp was the cobra 460 rated at?

Lakes Only would know about cam and intakes, although I prefer single planes on jet boats.

What heads? Later Fuel injected or older carb heads? Adjustable rockers or fixed will affect cam selection.

What exhaust manifolds are on it? If they are iron, I'd ditch them too, for weight reasons, and flex plate over flywheels too.

Most 460/jets like an 850, even mostly stock.

Just my $.02

Sounds great.

Will you be at the Thanksgiving regatta?

Wow, that sucks.

I'd wager to guess it's time for head gaskets. You probably don't want to hear that a rod bearing spun, so I won't say it. Chocolate milk shake doesn't lube too well.

If you can isolate the cooling system on the engine and pressure test it would be your best bet. About 18-20 psi. Logs can leak internally, so check that too.

There are guys that know a lot more about Olds than I do.

Best of luck.

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

Me and you are in the same boat ! Mabey it will pop up for sale on craigslist or offer up and Iíll see it there . I have a pickle fork hull that was converted from outboard to jet and I like it but unfortunately the exatensive work to the keel and glass will probably cost more then itís worth so I was to try a tunnel dragster

Not a boat, but what an incredible and unique custom rig.

A guy in Illinois just gave one away a couple of days ago. Idk what kind of shape it was in but he said he got it out California several years ago. Idk who snagged it or where it ended up going but that was the only one i have seen or heard if in a good while. But then again I dont have Facebook or anything and thats where it seems like everything and everyone is unfortunately
