The Pumpkin is treated like a total whore and she keeps on giving. That ski is proof that a properly set up stroker can be as reliable as a stock stroke motor but with a shait lot more power.
Strokers are only as good as the guy building them, if I was told to pull the motor down every 32 hours I'd look elsewhere.

That is how I see it. My 5mm will get tore down when the rod hangs out the bottom. I figure she'll need it then.

What oil ratio are they reccommending?

Our 8mils go an entire season on a top end turning 7800 plus rpm. That is with RAD or Crankworks cranks and Lamey PV cylinders and 220lbs of cpmpression. Basically, we put a fresh top end in the ski in Feb. and ride it all year long, racing, practicing, screwing around. If we can do that turning the rpms we turn, especially under load in turns, I don't see how setting one up for freestyle would be less reliable. As mentioned earlier, you guys aren't pushing the rpms we do, and its those upper rpm range runs that wear out a motor. I think someone sait it best earlier, it comes down to who builds the motors and who tunes them more than anything.
Just my opinion.

32:1 & Xscream said to run Mercury Marine Quicksilver oil. I'm running a 6mil stroker/860cc xscream built motor.
Another builder told me kinda the same thing on strokers, tear down around 75 gallons or so! I went with another shop!
Build it & let it rip!

I have been wary of quicksilver due to it being a different colour at least once a year. I have seen it be a dark-blue, brown and green. Got my favourite oil which gives excellent protection at a good price. Got asked yesterday if the Envinrude E-Tec synthetic oil would be good in a ski(seen as they reprogram the E-tec to inject 50% less oil when you are running it). Anyone tried it?

32/60?
My 10MM stroker 525 Banshee has quite a bit less stroke and bore, but I am on my 5th season riding it. I ride that girl like someone else is paying for her. 200 psi on race gas.
No less than twice a month during the season 10 hrs max over a three day ride. Crap, I probably have 100+ hours on my bottom/top end. I have top fuel honed the top end once after a jetting probem first weekend and after that, never been back inside the motor.
I will ask Kyle or Dan what their opinion a non-race/race motor program should look like.

I talked to Dan and Kyle and they both said the 30/60 deal would be the motor program for a RACE ski.
They both said 60 hours on the top and 100 hours and the bottom would be acceptable for a rec motor program.
Dan stressed that that is more or less an inspection and not necessarily needed to replace hard parts.

BTW,
According to Dan,
Yamaha's design parameters are to live at 200HRS wide open.

IMO 50 hours for a 1st inspection is pretty reasonable for a high-output engine. We can learn some lessons from the motocross people on this subject... treat a nice engine like a stock engine and it'll go BOOM on you eventually! :smashfreakB:
