Thanks, that's pretty cool!
I expect there is 800 to 1000 pounds missing from that boat with the missing cap, deck and console. I would bet that it would at least get up on plane and cruise with the rest of the parts installed based on the video.

Once upon a time, anyone on this or any other boating forum would have been quite proud to own a 20 ft Superfisherman with a 75 hanging from the transom. It would run in the 30's and suitable for offshore service, including a trip across the stream and a week cruising the Bahamas.
Today it's unsafe to venture offshore without 30 feet of boat and at least 2 engines; and a modern 20 ft v-hull boat with less than 200 hp is likely underpowered.
Meanwhile, a little horsepower and a well designed hull can still make for a great all around platform for inshore and offshore use.
Funny how perception changes over time.

Haha. That is hysterical. I want to know what their Min Plane Spd is!

I saw 9.7 mph on plane with Steve Matthews on the barrel back
cold molded prototype 25 from Tribute with a 250 HO ETEC.
Tribute uses a modified VDH design. OK, highly modified.

WOT was 72 mph and just buttery smooooooooth.

Ya know GFS that 250 eTec HO is a bad mother!! The opposite of Yamaha, you get more HP than advertised. Too bad they gave it up to the 4S engines. Oh well.

A pretty good indicator that 115 hp will work fine on a SC 20 hull.

that was cool, I love cave man engineering because the results are generally irrefutable...

It also took me a minute to realize it was the same guy I had watched free diving videos a while back. He has a few gems on his site that are worthy of a look if you're into that.

I'm sorry, but that G2 looked like Gumby on acid.What were they thinking.
I've seen better looking Edsels.

The 2 stroke design in my mind is still superior to the 4 st in many
ways. They chose to make the G2 heavier for some troubling idea.
Denny and I saw over 10 mpg on his seafari at idle in da Keys!

I can hold 12 mph at 3,000 rpms. Not too shabby there.

Did you all see the next video in the series when they took the same hull and put 2 more engines on? Added a 25hp Merc 4s and a 15hp tohatsu 2s and got it up to 33mph.
