Shim or No Shim with RXP Rideplate

[yellow4]

Referencing back to Shibby's research on tweaking the ride plate, what do you think about this guys.

I have an awfully big step between the end of my hull and where the ride plate begins, will shimming scrub speed or add.

pics 741 and 742 or no shims

pics 743 and 744 or shimmed

the rear of the ride plate support is higher it seems that the one in the front almost angling the ride plate higher towards the rear. Grinding down and leveling the back support would allow a more snug fit with the hull. Any definite results?


Tell me what you think, Thanks

Pm (Jim 1300) about this. He seems to be the guy to talk to about ride plates.

shim for flushness for sure!

Hello Yellow4, You want to shim the front of the plate without going lower than the hull you should have about a 20 to 30 thousands step. That will also change your angle on the plate and you will pick up some speed from it.

Hey thanks jim

That's what i wanted to know. So shim 20 - 30 thousands, but not so that the ride plate will be BELOW the hull.

Maybe with that, and a little more truing, I might have something better than before.

Thank You

correct you do not want the plate to hang below the hull because you will create a place for water to catch and it will cause drag, And you will lose speed.

Dumb question, but what are you using to shim the rideplate? Can you please give me PN?

Washers sanded to thickness and shim stock for real thin apps.

Can't you get shim washers from auto parts store, Sears, or lowes?

That picture was taken with a regular washer which was about 1.5 mm thick or so. I made a huge difference. I would probably use very thin shim washers and gradually build up I think...
