160mm liner and prop
I am sure there as few post on this but how are you guys liking the 160MM and what prop are you running. I am just thinking about what to do for a pump/prop setup

I had the 160 liner setup and didn't like it. Wasn't making enough power for it with the B wheel and R1.

when i did the 160 liner i had the the skat resized and repitched to a 12/21. which gave me rpms of 8000 to 8100 depending on the ring i used on the exit nozzle.
so, i repitched it again to gain some more rpms. i dropped the pitch to a 12/19 picked up some more rpms about 250. so i was about 8300 depending on the rings on the exit nozzle and lost another 2 mph on the top end.
needless to say i gave up and went back to the 155mm pump liner and had my skat resized and repitched to a 14/24. and i am getting real good results.......

The prop is the issue with C3/B1 power, there isn't one that I've seen that can get the rpms where the need to be without completely deforming the blades and making the prop ineffecient.

I couldn't get mine to work either. I chalked it up to my ski just not making as much power as I thought it was making.
Cavitation was totally gone but speed wasn't even close. Now I cavitate out of the hole but speed is good. Personally, I'd rather have the speed than the holeshot. This is after chasing the cavitation problem for a while.

Why not have the stock 155mm liner cut out to 157mm?? It would help get rid of cavitation some and would scrub less top speed than a 160mm liner. The only problem I see is getting a 157mm prop.

It seems to be expensive to get rid of the cav. About $2K for a Skat and about the same for a Sea-Doo Conversion. And with the Conversion, BidDaddy will be adding comments about how good the Sea-Poo shtuff is...

Im running a 160mm liner and 15/23... My rpms are at 8000 but at 80+mph...
I'm changing to a twin prop for the 160mm liner this week, 13/18 inducer and 14/21 main... Still using the stock 6vein pump also...
I like it and dont have any issues with it other than turning higher rpms I cant say I lost any speed with it... The new set up will put me where I want to be...
Btw, this is my Sunday bike... Not the race bike...
