RIVA SPONSON CONVERSION
Any one tried this mod! Works well for me in high speed turns and much better handeling.
We are making from Aluminium for extra strength.
Can someone else try this and post their results.

I gave it a try a while back, and it did help thru the chop and reduce porpoising, but slower turns weren't that great. I put them back to stock position for better wave jumping

I wonder what the defference will be with Pro block off or RE's instead of regular bo's?

Someone needs to make RE type block offs for the GTX/RXT so i can see what all the fuss is about.

I was thinking about taking some meat off of the riva sponsons and knife edging them. Do you guys think that would help anything?

Like the Jet Wings for example... they are the complete anthitesis of a Riva sponsons... the jet wings more closely resemble a stock sponson in taht they are wider and have more surface area beneath them.

Today we tested the sponsons we move back one position toward the rear of the hull and made a small Aluminium spacer 1"inch OD and approx 34mm long with an angle cut to support the existing rail.
We tapped a 1/4 BSW thread all the way through the aluminium spacer and fixed it with 2 bolts and loctite (Blue)
First test was in the Ocean and the water was reasonably flat so we reached speeds of 72mph @ 8160 rpm.
I cant describe the difference over the stock RIVA position it was beyond all expectations, we put the ski into high speed sweeping turns reducing it each time to see when the ski would break traction and spin but to our surprise it just keeps gripping and you can pump the throttle early out of a turn and it stays hooked. Im not sure how you guys ride but we are not faint hearted and take everything to the max.
The swell picked up this arvo as we were testing and that gave us the chance to put this to a hard test. time to wave jump and carve up the waves as we lean the ski into a wave and pull out full throttle and yes same result. Excellent
Also we opened the ski up full throttle 72mph and made the ski sweep left and right and this is where is works the best and feels so much safer as is wants to go the direction you point it.
CONCLUSION ILL NEVER GO BACK..........A MUST FOR THE RACER
HERE ARE THE PICS!
