Trim Tabs/Plate Setting In Rough Water
Hi Guys just seeing what everyone s set up is in rough/choppy waters.
My current set up is Jims FF plate at .980, R&D Tabs at .120 OEM Sponsons stepped took the ski out ride well but when the wind picked up trying to get through the chop was nt easy.
I know by lowering the plate will help allot but would the tabs be better set flat against the hull instead of spaced.(for choppy waters)
Maybe Jim can answer best here or other with open sea set ups.
Best setting for Jims FF plate in rough water
Best setting for Trim Tabs spaced or flat with the hull
Sponson Oem Stepped or R&D Sponsons.
I am trying to work with the Jims plate i know the OEM works best for rough seas have you guys added an extension to the OEM plate.

I love my Jims FF Plate also but in the rough stuff just put the stock plate on

On my daughters boat I run the plate at .750 with the R&D tabs up against the hull with no shims. This has proven to be an excellent rough water setup with great turning ability and not that much loss in speed. If you work with the plate it can be more fun then the stock. Ski runs low 73s like this and low 75s at .980. Also I use the OEM engine shims that are U shaped so it just takes a few seconds to slide them in or remove them.
Most of the time I run around .900 on the ported boat just for the extra handling.
Both boats are using the FF with the front almost flush.

XLT nozzle (3degress rather then the GPR 5 degree one) and stock plate is the way to go.
The ski will fly through the rough stuff, stay hooked up and feel like a completely different ski.

My main reason for posting was more info on the Tabs setting in rough stuff..
It s proven that the stoke plate is the best with a 3 degree nozzle. I am trying to get a medium balance with the FF plate with good top speed and able to get through some rough stuff.
Jim I loose to much speed with my tabs at .200 will start lowering my plate where i don t loose to much speed and see how it goes in the rought stuff.

Go over to the stock plate and then xlt nozzle and I can go easily 5 MPH quicker through the rough stuff and for longer as the ski stays hooked up easier and therefore less of an animal to control.
This is all about compromise for the conditions that you ride in.
I've tried the angle plate route and there is just no comparison when it gets rough and the ski spends most of its time in the air. A bit like having slicks on a race car when its raining. Yes they will go faster but not in the conditions your in.

With my unported 1300
In flat water trim 78+
In rough water trim 68+
My rough water set-up is as follows:
Shred master rideplate (not modified) (-4 mph)
XL1200 (3 degree) pump nozzle (-1.5 mph)
Bullet trim tabs (modified to be used with the Shred plate, tabs are flush to hull) (-.5 mph)
Skat setback 14 vein pump
Skat swirl 16/25 swirl impeller (-2 mph)
Modified worx 1200 intake grate (-2 mph)
Protec steering nozzle

...when the CC racers use a Riva / R&D plate they install 3 or 4 large washers under the rear bolts - as suggested above motor mount shims would be ideal
