I was going to move my plates up, and had a few questions for ya !

1) Can this be done correctly w/ the boat resting on the trailer in its normal position or do I need to slide the boat back, so the plates are not on the bunks ?

2) It is a runner bottom...so, do I make the same adjustment all the way across or is the center plate done differently ?


3) Do I want the plates dead straight or do I want a little arch in the middle ?

4) Does anybody care to share "there way of doing it" ??

Thanks for any help.

I didn't read the linked info, but I will say that every boat is a little different and any suggested settings are more of a ballpark number than etched in stone. Experimentation is the key once you're in the ballpark, and it is critical that all numbers, from the very start, are recorded in a boat log. Write it down!!! If you know where it was, you can always put it back. 1/8 of an inch is a lot once you start fine tuning.....Write it down!!!!...........Ray

Perfect! Once you find out how, you can help me with the plates on the TR2 this winter....I drove up to Fresno this morning and put a deposit down on it. Should have it in the garage here shortly.

The guy you want to talk to is Jim Lange. I know how I set my plates but I do it a little differently than most. I set it up to where I can get off the down pedal. I have to drive it the whole way down the track on the down. Most people I have talked with don't like doing it that way. There are some good threads in here from the past that have plate setting tutorials. Fiat48 is another great resource to help you with the plates. If you want the way I do it, send me a PM and I will fill you in.

I think what he meant to say was he sets it up to where he cant get all the way off the down pedal. The boat will be set up extremely ( loose ) and will need some down at all times, there for he will be DRIVING the boat all the way down the track on the EDGE!!! Tony let me know if I fuc-ed that up:)sphss

Here is the last post I could find by Jim about setting plates. This seems like a pretty good description.

I'll try and make this as simple as possible. Keep in mind, this is ONLY a guideline. Not all boats like the same setup. It depends on the bottom, horsepower AND the installation setup. Like Bob aka "Fiat" stated, start with a straight edge at least 30" long. Take a 3-6" piece of 1/4" keystock and clamp it it the very back edge of the plate with a vise grip clamp, leaveing access to the area behind the far right plate boss. Protect the top side of the plate with a non coragated piece of cardboard or what ever. Place the straight edge against the bottom of the boat approx 6" forward of the recess. Adjust the plate up or down to just touch the keystock. Do the same for the left turnbuckle on the right plate. Now double check the right. If you have a TR1 or Hondo 511 with 3 turnbukles, do not set the center the same. I like to split the difference by putting about 1/8" gullwing in the plate (side to side). Now go to the left plate and do the same. The center plate is done by adjusting the outer turnbuckles the same and the adjust the center turnbuckles with the staightedge across the width till the plate is flat. Then double check the outer turnbuckles on the center plate again, re-adjust if it changed. Sometimes if the plate is way out of adjustment and you have to turn the turnbuckle alot, it will change your setting on the outside. Always go over it twice. From the 1/4" setting you can go up or down according to all your other variables. Driver experience, horsepower, setup... If you are unsure, it's best to set it 3 flats down from 1/4". Now here is where it gets tricky. If the bottom has never been done (or done by someone that's not as good as he thinks) the area 6" forward of the recess MAY not be flat! If this is the case... split the difference the best you can and spend a little more time with it at the lake to see what makes you happy. Good Luck, Jim

I always called that "controlled flight." It's all about how much air was packed under the boat (how dry the set was) when you set it....as to how much...along with how quick you can get off the down.
Dry boats = big numbers.
But deadly in the wrong hands......and sometimes in the right hands.

No truer words ever spoken. Too many people do not understand THE PLATE.....and how it works.
