GPSHO or GPRXP?
I just picked up a very nice low hour 2001 GPR and think a conversion is in my future! It will get ridden for a little while until I can gather everything that is needed for a swap. Then my big bore will be the wifes ski and I will sport the conversion. Now for the BIG question....
should I build a GPSHO or a GPRXP? Lets hear the pluses and minuses of both people! Especially from someone that has ridden both skis.

the SHO will cost more, they are newer skis so the price hasn't come down as much
the SHO has the potential to make more HP, it is a bigger notor
not sure about this one, but I think the SHO would be heavier
the ride with either will be great, smooth effortless power

All what phillip said above... SHO can make more power but costs more and should be heavier
I have GPRXP conversion, and throw it around like my old two stroke, handles very well both high speed flat water, and perfectly ballanced for wave jumping.
Also working in the engine bay is very easy in a GPRXP, I actually find working in their easier and more room then when the 2 stroke was in there. I'm not sure its so easy to work around the SHO engine ? maybe Philip could chim back in?

So much can be said for both conversions. I have been fortunate to have a SHO conversion and have ridden Duke's monster GPRXP's. May want to ask him his opinion. I will tell you that there is not a whole lot of room to work on a SHO engine when its in a GPR hull.
Like Philip said, modifying SHO engines are expensive, but the build a ton of power and running 100+ with a properly set up ski is not that difficult, but it is costly.

If I were to build the ultimate rec ski it would have a low boost SHO motor in it and probably hit low 90s easily on pump gas. If I were looking to build a drag boat it would be a high compression RXP motor all the way.
SHO motor weighs 138 pounds more then the SD motor. Yami is also much more expensive at this time.
A current customer wants a SHO conversion that will hit 100 and use SD pump setup. Going to see how or if it can actually holeshot with all that instant torque and weight.

I really really really like my GPRXP.....snappy, reliable, powerful and super easy to work on.

I have done both, and the SHO is a lot easier, but yes more expensive.

I HAD WORKED ON BOTH OF THEM AND YAMAHA IS EASY TO WORK WITH AND MORE EXPENSIVE THEN SEA DOO BUT WAY FASTER THEN SEA DOO TOO
