T2X wouldn't approve, but we turned the #3 speedy props in and it made a positive improvement in high speed handling. You have a different situation with the Arnesons since the props are farther aft of the transom. You might try contacting a good prop company like Throttle Up; sometimes a prop change can help with "hop".

I do not think that throttle up can help me. Big shaft Arneson splines are different than any other. You can have a set made, but i do not have a wallet like many of the OSO crowd.

Are you certain that these are ASD8 drives? How many splines are on the shaft, 19 or 25? If they are 19 I make a propeller adapter to allow one to put SSM#6 propellers onto a 19 tooth spline shaft.

I know of a Cris Cat with ASD6's on it that was out if MI.

Tschiggfries old Cris Cat with SSM#3 drives porpoised severely, we upped the diameter on the propellers some and it helped some.

Your CG is in the proper space for the boat and you do have a good top speed, how much cup is in the propellers?

Rik If this is the rick from Arneson, we have spoken before and you helped me with steering parts. These are big shaft (25Tooth) ASD8s #0802BBK60092 & 93. Came through Tim Drake in 95. Put big shafts in from Erol L. in Fla. in 02. I thought you made a set of rocker plates for Rod's old CHRIS CAT?? I do not have a clue how much cup in the props or how to measure??

Rik

I did, the boat was far better he said.

I sold his boat to a guy here is CA, he blew the SSM#3's as soon as he got it. opps.

Thanks all for the info. I sent an E-mail to George Linder, the man responsible for the CHRIS CAT and he called me. He was not only very friendly but also very helpful. It seems that I am not supposed to have any hook in my steps so it is time to grind and fill.

jeffery Hi ! Just lurking on your thread and have a 10 cent question ! I throttled in a 40 Fountain called Executioner in 90 and I remember Tropic Heat was a bad a$$ boat ! There was another Chris Cat in D called American Express, Jimmy the owner of American Express had his tabs set to where he liked them in all conditions then replaced the trim cylinders with a section of pipe ! Are your tabs fixed or movable ? Thank's Ron OPA P4-33 STEELINTIME , PS. We could only out run those F~#&@ng Cats in really big water !! Good Luck with her !
