Wildman put a 450R V8 blown (replacement for the 400R inline) on a 21 Liberator. 1st time out 120+. Has his eyes on 130. I doubt that motor will ever be on a Hydrostream (too heavy)--but ya never know. $60K+ motor. Editorial on S&F said 100 was once considered fast. Now these guys cruise at 100. Woof. Mercury a year behind on production of V8s.

Hope the Vegas got figured out. LWP V6 four stroke might be the current way to go. BRP only 2 stroke. Evinrude 225 would be sweet on a Vegas.

There is this one he built with a new 300R on it.

Wildman, AKA Randy Corson over on Scream and Fly. He builds Liberators and some Checkmates and the guy does way beyond amazing work. His boat builds over on S&F are nothing short of amazing.

Guy knows how to build fast boats that look amazing.

Wildman now 106. Woops, make that 112

I-6 going away (15 year old technology). 400r+ will be v8.
300R naturally aspirated. New 400R+ V8 blown?
I think a Vegas could handle a production V6 225 4 stroke--but lower Unit? Cone it as in the past.
There was a Evinrude V8 on a Vulture (blew my doors off--and I didn't even have doors) and on a HST. Weight of a Evinrude V8?
The new 115 Pro XS 4 stroke weighs less than the old 115 Pro XS 2 stroke. 2.1 Liter vs 1.5 liter.V6s and V8s are doing the same. Weights are coming down drastically.
New Verado 150 lbs lighter. Wooof.
Wildman just ran 103 on a 21 Liberator with 300R. Ran 101 with 300 XS 2 stroke. 4 strokes getting lighter and faster everyday. Good for Streams.

New 400R should be out soon. V8 4 stroke. A pair of those on the back of a Skater would not suck for performance. 130+ mph boat. Roughly 300# lighter than two 400R Verados (Inline 6). Not too many 2 strokes running 130--right out of the box.

The 2018 Verado 400R is already out. And its still an inline 6 / 2.6L engine. And still [b]668 pounds[/b].

So I have to wonder - considering the specs of the 400R - why their other models are significantly larger, yet put out less horsepower.

Secondly, this isn't a Skater forum, nor are people putting 2 motors on the back of their Streams. I'm sure if you could manage to stick 2 400R's on the back of a Vegas or Vulture, it too would be a 130+ mph boat. But that ain't happening, ever.

Lastly, Hydrostreams were never designed to handle and balance the weight of 4-stroke motors. Not saying it can't be done....but would it be worth it?

300 Pro XS 6200 , 300R 6400
Didn't realize the 200 Pro Xs & 225 Pro XS were V8s
Production v6--175-200-225

New 400R should be out soon. V8 4 stroke. A pair of those on the back of a Skater would not suck for performance. 130+ mph boat. Roughly 300# lighter than two 400R Verados (Inline 6). Not too many 2 strokes running 130--right out of the box.

Still ridiculous. V8, 505 lbs, and only 200HP? It's a 4.6L engine for crying out loud. Just one more reason 4-strokes suck for performance.
