Hulls / Re: Intake Side Fins - Cut 'em Off!

the pivot point moves at different speeds and different centers of gravity,
I agree with this. The pivot axis location depends on how much of the hull is wetted or down in the water. At slow speeds there is a lot of hull in the water and the pivot point is as far forward as it will get. Think of your hull as a giant, blunt weird shaped fin. As you increase speed and the hull starts to plane then less wetted area and most of it further back, so now the pivot point shifts rearward. And as you get ultra fast and start flying the hull like Beerjet always does, then there's very little hull in the water and the pivot point is way back at or near the intake area.
All of what I just said is b4 adding turning fins/skags up in front of the pump inlet. When these are present, then the pivot point will "cling" to their location, because they become the fulcrum for the turn in stead of the hull itself.


Eeewwww!!
Last time I saw it was when I laid it on the roof of my truck.
There seems to be a common denominator, guess I better keep my eyes open for a good used motor and VFD?
I had broke ones too. Do what Brad sez. Carefully drill out the centers with drill bit no bigger than ID of threads. OK if you are off center a bit. Then EZ out or pry the shell of the screw out. Then drill out the old threads and put in 3/8 or 7/16 through bolts with self lock nuts. Spooge a wad of silicone in the hole as you put the bolts in.
Anybody got ideas about what good they do?
