It's a big heavy full cabin boat. Bow lift might not be what you expect it to be without putting it on a diet. Turning the props in should give more bow lift. I believe adding cup to props will also give you more bow lift. More blades turning out might make it bow heavy (stern lift) and bow steer, but turning in should also give more bow lift. This is a staggered boat, correct?

I'd just enjoy it right now. I don't believe cams will do much. I'd save the money.

Not trying to set the world on fire but feel like it has more there in the drives/props.

Appreciate the insight! Yes its full stagger. I already had to change one of the cams since the original engine builder used the wrong distributor gear and it killed the gear on the cam. So I wanna change the other this winter so the engines sound the same.

Glass Dave’s favorite boat!!!

My 12 m runs 85 plus gps with NA 565’s SBS and sm3’s. Timing at 34 deg. 5,400 rpm +. 16 3/4 x 27 cleavers 3 b turning in.

last weekend was a little snotty in lake MI. Wish I could post a video somebody took 😂

edit:: BTW nice looking boat!!!

Is it really Daves favorite or is that sarcasm? Hahaha I'm out of Hammond, wind was out of the west so not a bad weekend for us. Where are you at?

We need couple more pics......:ernaehrung004:

Not a pro at these model boats but really like the look! I would have thought it could be much faster with 730 hp ! Were nt they running low 60 with stock 400 ish hp? I would have thought min 80 plus mph !

No for real. I talked to him about a year ago anbout some repairs and we had conversation regarding hulls. He loved those boats in rough water etc. Only sacrifice was the speed for known reasons but yeah his favorite at least what he told me.

NW Michigan, Manistee - Frankfort area

So back in the day I had a 38 Scarab flat deck with merc 475 turbo's that I modified by adding intercoolers and wastegates and upping the boost to a modest 6 to 8 pounds and the best I seen was 73 mph. I swapped the drives also and turning in was worse as it lifted stern but not the nose at all. Bottom had slight hook especially in chine area that never let the boat loose. Like you said water breaking north of the windshield. So the combo of the hook and the drives so low just kills this hull from any top speed. My friend back then had the same boat as yours (377) with staggered merc cyclone 400's and it was a 60 mph boat. He would trim up the drives until it threw a roostertail but the bow never lifted. The 30 Scarabs at least had some rocker to the bottom, I had a few of those.

Super cool boat, nice to see you got her back together and running! Mine's the same hull and about the same power. (650-725). But I don't have anything in the cabin yet. I checked the bottom of mine, and it's pretty flat. (one side has like 1/8" rocker, other side like 1/16" hook) You can see in this video even with the arneson drives, and props spinning in, although I'm not full throttle here, I'm not hardly toting the nose. With 5 adults, and half load of fuel, I think 70 is very respectable.
And it's true, Dave does like these old boats. :)
