Jet Pumps / Re: Sanger Super Jet Intake Install
« on: September 03, 2018, 12:34:44 PM »
You are going to be limited on your jet install if you want to retain the original round cutout and Sanger ring.  You pretty much have to put it in exactly the same location as it was originally or the pump won't line up with the transom hole.

If you are open to glassing and recutting the transom opening, since you are already working on the transom, you will have some options.

Largely, your options are driven by your intended use for the boat.

Regarding the wood installation in the transom, stop it short of the opening(s) so that it can be completely sealed in fiberglass.

I may be the odd ball here but I thought the removal of the pump in my sanger was less of a pain in the a$$ than the one on my TX-19 with the berkley adapter? Just my .02 worth and Yes the Sanger ring looks super bitchn compared to the berkely.
Agree the TA is unique Stuart , re the intake this one was "stuck good"
Heres a couple shots of just the intake :

Josh and I have done countless intakes and jets but this was to say the least "Challenging" the Transom adaptor as said slips over the bowl oring and is bolted thru the transom (except for two studs at the bottom) all the intake attching bolts seemed to be "threaded" into the fiberglass as well as having washers and lock nuts , The Intake is "dedicated" meaning unlike a standard theres really no movement to adjust to "Keel" We'll put up more pics later Tom

Jet Pumps / Re: "A" impeller VS "AA" impeller

Hey Skip,
Are you even more confused than before ??? I sure am. I think I will leave my pump alone. ;D

To end the confusion once and for all and get the thread back on topic...

Quote from: Jetaholic
If this helps...

An AA impeller spinning at 5500RPM will move more water and generate more thrust then an A impeller spinning at 5500RPM.

However, due to the fact that an AA impeller moves more water at 5500RPM than an A at 5500RPM, it loads the engine more, which requires more hp to spin it at 5500RPM than an A requires to spin at 5500RPM.

According to the Berkeley Impeller Curve Chart, an AA impeller spinning at 4900RPM will move the same amount of water and generate the same amount of thrust as an A impeller spinning at 5200RPM. This is because an AA impeller at 4900RPM absorbs the same amount of horsepower as an A impeller spinning at 5200RPM. However, this is theoretical and assuming a perfect world, so there is a give and take depending on other factors within the pump.

If you swap from an A to an AA without making any changes to the engine, your 100% RPM value will drop...how much it drops depends on the hp curve of the engine.
