Ride plate fitting on GP12R

[AndyW]

Should my ride plate be flush with the scoop grate or should it be higher. I have a carbon ride plate which when fitted sits about 8mm higher than scoop grate? Is this right or do I need to shim down the plate??

I assume you mean higher then the pump shoe. 8mm sounds a little high but the CF plate is umfamilier to me. Most of the CC boats I have seen were close to flush. Who made the plate?

The ride plate is made by r-pot and is made from carbon fibre. Yes I do mean higher that scoop. If it is not near to flush will this affect speed/handling.???? If so what gains should I expect if I shim it to the correct position????

Can you post a pic. I am not sure what type of setup may be on your boat. The rideplate on my GPR is up against the shoe not the grate. The grate is then bolted in the shoe 4 or so inches in front of the plate. Either way 8mm sounds to high but a picture would help.

Anybody help with this one????????

Its hard to tell how much you have there but my Jim's FF plate has the same type of step from the shoe to the plate. I was told this was ok.

Andy,
What do you want from your ski?
Great handling, or top end?
That R-pot plate is quite long, and even with more angle with shimming will always be a slower plate. It is very good in the rough/closed course, but it is probably costing you the best part of 4mph on it's own!
You could try shimming, but I think it will induce more porpoising.
Step the sponsons to calm it, but if you are after speed, it's probably best to ditch it.
BTW, the step is fine

I am more after speed, my days of racing a course are gone!! Will try and get a good second hand plate either riva or r&d? any suggestions for best top speed???

[AndyW]

Is a stock ride plate anygood on the gp12r as can get hold of one?? All I want to do is go a bit faster....any more ideas anyone????
