Hydrostream Viper

[jpeelout]

I'm doing a full resto on my '78 Viper and am thinking of putting my 2 stroke 90 Mariner on it. Anyone have a Viper with a 90 on it? If so how does it run? Thanks in advance,
Josh

It will run about 55 if set up right

[jpeelout]

Was hoping for a little more but, that's ok. Will at least get on the pad?

Thanks,
Josh

mine has an 85 hp four cyl merc and runs about 55 or so. It's a short shaft.

Ronnie,
I take it that you have more than one, I've seen the brown one with the Gianormus neuclear reactor on it! LOL!
Thanks,
Josh

[jpeelout]

I'm putting three modified HDPE seats in mine, center steer with sxs in rear. thinking of putting my battery in the center just in front of the bulkhead w/ tank in rear.

[jpeelout]

Kid, what year is your boat? Mine's a 78.

[chargerk1d 2]

No, it will take low 60's to get it up on the pad. If you set it up right, you might get close.:thumbsup:

[chargerk1d 2]

It should get ob the pad in mid 50 s mine is light and if we set them up good the should c 65 to 70 set up really good wit some little mods

[jpeelout]

Kid,
What pitch you runing on the 90? I have a God knows what kid 21p with a merc small shaft on it. It came on the 140 Chrysler Charger. Lower looks just like an old force, power head is an I4 twin carb and it has lwp on the stock gc.

[jpeelout]

Sorry, I got a little careless while typing and talking to my 3yr old! It's got a 21p with a small shaft merc hub.

Kid I plan on having my family with me most of the time so I need the extra room for the seats, otherwise I would have one seat in the center and weigh the hull with me in it to find the right setup for weight placement, gotta get as close to the center line of the pad and as low as possible with the center of gravity as you can.

i have a 24 chopper on trying to get a 26 and then im ganna get a 28 with a drag cut put on it and it should rip with a nose cone and im ganna raise the motor up on a jackplate

[jpeelout]

I'm gonna get a plate too but have to wait for a bigger prop. Have my 21p on my skiff right now and have yet to try it, been way too windy!

No, it will take low 60's to get it up on the pad.

Yes it will....sorta. My 25" V4 ran my boat 62-63 completely buried 7" below the pad and it was just barely getting there. Turned it 6400-ish with a 12.75 x 23 junk prop. Keeping in mind my boat was rotten and wet also. Just don't expect it to do it with a full fuel load, 4 people, and 3 coolers. :thumbsup:
