Flipped the hydro over today, sat her on level ground and it looks good. No twists, sponson afterplanes are both touching ground along with the pad on the transom. Next the plans call for some shoring before we add 3 layers of spar varnish over the interior. Once that is done we can add top battons and 1/8" meranti ply decking on top sides. We finished up nose cone on the frankenmerc, dont look too hard, it's not beautiful as the kids faired it. Just have to finish up a little electrical stuff on it. Project is moving along nicely.

Looks great, proud group of kids there! Glad youngsters these days are still able to get their hands dirty and build a project like this.

Hahahaha
Not sure what you mean by tieing in bulkheads in the front. We are going to add some structure when we do the steering and whatnot up in the bow, still a ways away from there though.
I know it doesnt look like it but the motor is already a 15 inch shaft. We put it on the boat temporarily just to be sure as we made the transom 19 inches for a surfacing prop and low water pickup. Maybe you guys could give me your thoughts on motor height, we can still come up a bit with some shims, I'll try and include some pics.

I've come close to 70, but I have way too much weight in the rear still. I relocated the battery to the front, but the fuel tank has to go up there also. The bare hull weighed 505 lbs, and the motor is just under 400 lbs. Plus hydraulic steering setup. Plus the jack plate. I probably have close to 450 lbs hanging on the transom.
I say I need more weight forward because it still porpoises around 60mph. I've messed with all sorts of props and engine heights. Too high, and I cant even get on plane. Too low, and she's slow. I'm sure I have the right height and prop, now I just need to work on the balance.
Wood Butcher. I love it. I think that may be the name of my tunnel hull that I haven't named yet... GENIOUS, DAVE!!!
2" below the pad is usually a good starting point. Many members have good luck with that as a rule of thumb to start with. If you have cavitation issues getting on plane... drop it a bit. If not.. just monitor water pressure.1) 1995 14' Bayliner Restoration <--Click

Try some stain before painting it.
You might be surprised how good it looks.
You can come up w/some stripes to hide boo boo’s if you need to.
As light as that boat is, you should be able to run the propshaft even and it will still jump in plane.
If the motor will pump water that high.
Start watching e-bay for props. You’ll want as much ouch as you can find.
Watch gas tank size, weight and placement. It will have a huge effect on attitude and performance.
Keep it aft if you can.
The hull will build lift and try to carry the bow at speed.
We Used to run real small, 2 or 3 gal tanks mounted right against the transom.
We also had some tanks that hung on the back of the motor.
Make sure and wire a kill switch and run a dead mans throttle that returns to idle/close if let go of.
That thing should be wicked fast w/that motor.
Be careful.I'd rather be competitive w/junk I built in my garage than win w/stuff I bought.
I refuse to allow common sense to interfere w/my boat buying decisions.

Ronnie, we are going to need cable steering. I am looking around online and am having trouble locating something. I could probably rig up some redneck home made stuff but I want the steering to be legit as possible. There is a lot of power on the back of this boat. I have been keeping an eye on local stuff via craigslist put pickings are slim.

I am going to to test it with another member of my department first. If it is safe we will then let students test it (so long as they have their boaters safety course). I will have my boat out as the mothership and command center of the operation. Some detuneing may be in order.
