Here's an answer to your gearcase lift issues: Water pickup low in the skeg leading edge. Get the entire case out of the water.

I've been thinking this way for years. But I wanted to cast the gearcase in stainless so we could make the skeg thin as hell and strong.
WOW! Very cool!
The bearing carrier is epoxied in place per Hydroplay's recommendation. Exhaust path is through the (now above water) housing as required by APBA rules. So far, we've had no issues with the carrier coming loose. The same can't be said for clutch dogs and pinions which have proven to be the weak point (for the SST-60 housing). Then again, my powerheads over-deliver, and the driver is very aggressive.
A slotted 6061-T6 leading edge cuff and nose cone is welded to the gearcase and skeg. Though not skeg thin (a channel is needed for water), it adds strength at a small fraction of bullet frontal area. The cases (two built so far: one SST-60, one Hydroshift) handle better than the plow, and accelerate like crazy. We've not tested top end yet - props are all different. BTW: Ron supplied one of the props!
BTW: I'd provide more images, but the site is having upload challenges:-(

I humbly invite you to our races sir, the more the merrier.

If only I lived closer, you'd see me on the course.
Just trying to be helpful and provide solutions to make your racing faster.
The new shop is just now ready for work. First up: Six 7-1/2" towers for the 45SS/OMC nitro gearcase. These use Mercury clamps are drilled for the OMC 45 twin and 49/56 triples, but can accept pretty much any power head.
The race never stops!
That's a really smart looking solution, nice work!
NOW THE MOTOR ON THIS BOAT IS INTERESTING!!
Look at the horsepower listed. 75 HP

The mid is a 50 hp short shaft. Did Hydro Tec rework a 52 cubic inch to fit or did they built it out of a 42 cubic inch or is it Fake News in the ad??
