Installing a Bowl Stuffer into a Berkeley 12JG Jet Boat Pump

[@chrismann1915]

Thank you for showing your mistakes and how to fix them, helps younger guys like me and I don’t feel so stupid when I make the same mistakes

Nice vid. For me I think the bowl stuffer mod would be quite far down the list of pump mods. I'd really like to see some data or back to back tests on what difference it makes to holeshot etc but there seems to be nothing out there on this. Also with drilling into the oil chamber you now have swarf in the chamber which could get into the shaft bearings and seals. I guess its really for the guys wanting that last bit of performance from the pump.

I am in complete agreeance with you. Adding a stuffer to a pump is a mod that should be at the very bottom of anyone's list of mods to do. ~ NIck

Looking forward to the next video on this! Huge help and great detail. Beats the 14 second video the company puts out

I was cringing as you were marking those holes having made the same mistake. You cannot even do that with woodworking let alone something that needs to be done extremely accurately. Next lesson you’re about to learn is all that crap that you’re blowing into the center of your bowl is going into that bearing. Don’t be surprised when it wears out early.

No need to worry about the bowl bearings/bushings. I took my time to clean out all the aluminum bits within the cavity... ~ Nick
