MSX 1500SC Project

[beerdart]

Picked up a 04 MSX 150 Hull. Now I need a power plant for the old girl.. Me thinks a Seadoo 215hp SC 4-Tec??

Isn't the 04 MSX have the best hull for the newer skis out there?

Nice find. looks mint!

very cool , cant wait to see what you do with this

best part is it was designed by the designer of the fastest hulls out there ------GPR

[beerdart]

Any speed predictions??

[jkindt]

Congratulations! I dont know how fast it will be, but I do know that you better HANG THE ____ ON when you hit the throttle!!!

Is that the hull the guy was GIVING away????

If so, that thing looks NICEY nice.......


Why stop with the 215 HP SD engine? Go for the 255!!!!!!!!


This ought to be another nice build to watch take shape.

[beerdart]

215 and the 255 are the same engine the 255 has external intercooler and bigger SC my plan is to push 14 psi boost @ 8600 RPM should be good for 300+ HP. I still need to figure out what pump to use.. Polaris, Yamaha or Seadoo??

wow makes me want to do something with my hull now.. wheres that V6 mercury engine when you need one.

Twin turbo Merc V6 with a shot of nitrous just for added fun!

HOLY MACREL!!!!!


Didn't the boys say the Polaris pump would hold it back after a certain speed? (Too small)

Maybe use the Yamama since you can swap parts between this and your GPR?

About F'in time you come back from the Darkside........I'll put my money this will see the water before Hydrotoys does. You know me,I'd say start with the Polaris and see if there will be a wall(for the sake of others to follow). Then you could always look at the guys in Fla. that was clicking 80+ with his mod.

And make 2 of everything......another may follow close behind...

Polaris, Yamaha or Seadoo??

What did the GPRXP guys decide was the optimal pump - Yamaha or SeaDoo?

The Polaris pump will bolt right in (custom drive shaft course), but would probably have trouble hanging on to a pimped out 4-Tec's power. Cavitation seems likely

What did Hydrotoys choose?
Rotax powered Polaris MSX

[beerdart]

The GPRX's there is a toss up between the Seadoo pump and the Yamaha both have good top speed. The whole inlet to the pump plays a big roll in how the pump preforms. I will most likely go with a Yamaha pump as I have the parts.
