    SHO grate on smooth water?

    Was wondering if a grate would buy me anything if I mostly ride smooth water?

    I found a post by Jim stating that the R&D grate will actually loose speed.

    Just have minor mods, ribbon delete, filter, and FF exhaust. Working on a prop change and will be getting my plate to Jim. Is there any reason to upgrade the grate with these mods riding mostly smooth water?

    I run the Riva grate and it's doesn't seem to slow me down at all. I have no personal experience with the R&D grate.

    we picked up 1/2 mph with the riva grate over the oem grate, the R&D grate is said to be a little slower in smooth water but faster in the chop due to a bigger scoop design wich hooks up better.

    Even in flat conditions an aftermarket grate will make the ski handle better & more stable at speed because the wing on the grate keeps the ski more firmly planted. The only negative is it tends to allow more weeds & other debris to get stuck in the grate & possible enter the pump if you ride in areas with lots of floating vegetation.

    I gained .2mph with the Riva on a back to back test against the stock grate with everything else completely stock. The R&D definately hooks up better in the chop, but as Jim mentioned there is a slight speed loss. I didn't do a back to back, but from one day to another with similar weather I think I lost 1-1.5mph compared to the Riva.

    I didnt take any speeds with the stock grate, but i did get 66.5 with the R&D grate and no other mods. The only difference i noticed from stock is that it slows down a lot faster.

    Thanks for the responses. Think I will pick one up after the dust settles with getting the prop dialed in.
