I never got past any glass, the notch the pickup goes thru is 3 5/8" thick. I estimate the hull to be 1 1/4 inches thick where the slots are. This from measuring at the drain plugs. These old girls are heavy duty. I know on a Beak I would have ground thru. I am waiting on the gel coat to cure now. Then we will bolt it on, and install the drives again. They will probably need 1.5 spacers, but we will try several.

I kind of figured that . Cool.

Pickups complete, drives back on, plumbing done

Looks great ZP . I have a concern on mine and I would think given those monster pickups you have the same situation . How are you managing water pressure . Does the system have a bypass of some sort you can manipulate or is it just done by changing the height of the adjustable pickup. My pickups are fixed and I am not a fan of the grind to tune method .
RG.

On my boat it was grind and tune, on this one the pickups are adjustable up and down, so we will control it that way. The engine comes back from Chief Wednesday, so we will install it this weekend, it needed a new oil pan, the PS cooler dripped salt water on it and made it ugly.

just read this entire thread..

what a read.. glad i read it. you did some amazing work on this boat. i love it

Can't wait to hear the numbers . Are you going to start with spacers or run as is and then add to tune ?
RG.

Awesome work as always, Here are the pick-ups I built for my boat.
Same concept with keeping pick-ups above running surface, and allowing
water to flow up and it. Had 90 hours in building them....

Also notice the adjustment arm on them, I can adjust the internal pipe up
or down from inside the boat until I have desired water pressure.. then lock in place.

Very nice, great craftsmanship.

We are going to try it at the 2" higher location, but we have a set of 1.5 and .5 spacers ready.
