Ride Plate?

What is the advantage of a ride plate. I have two pieces of a ride plate setup that came with my boat, but I am debating whether or not to get the third piece and install it while I have the intake out of the boat. I have a 1979 19' Hawaiian with a Berkeley 12-JC-AB pump with a place diverter. Would a ride plate help me with anything. The boat hasn't been in the water for over 10 years.

Put up a picture of the bottom of your intake and the hardware pieces you have.

I have pics of the entire build on my profile page. Everything but the bottom of the intake, I will get some of the intake shortly.

Need pics of the pump intake from the bottom. A shoe/ride plate is a must for the performance minded boater. Provides potential for increased speed but more importantly it allows you to tune the ride of the boat for best speed as well as load the pump more effectively than without.

Since you have some parts for a rideplate installation, I have to wonder if your intake hasn't already been machined.
No, the intake hasn't been machined yet. The shoe is the part that I am missing, unfortunately. That is the only piece that I can't make myself. I would have to do the machine work to the intake. I bought the boat off of a friend, and it hasn't been in the water for over 10 years, and the last person that tried to put it together spent a whole lot of money on performance parts, but was arrested for drugs before the boat was ever put together. The guy I bought it off of probably has the missing pieces somewhere, but he can't find them.

The boat only has a mild 427 truck block in it. We have the rev limiter set at 4300, so it is by no means a fast boat, right now. It is a fast boat, but a slow motor.:( I got the motor cheap and the boat even cheaper.:D

while the intake is out of the boat send it to a pump builder and have them machine the intake and provide a shoe. it would be best to have them machine the intake for you because they will match the shoe up to fit perfect

I am a manual machinist. I'm not paying somebody else to do the work for me. I'm cheap as hell. I've only got like 5 grand in the entire boat, and I made back like 2 grand by selling all the extra parts that came with the boat. It came with 2 1/2 pumps and 2 extra nozzle set-ups and some performance pump parts. But out of curiosity how much would a pump builder charge to do that? Because I don't have a lot of time to do all of that right now. But again I'm in Kentucky, not a whole lot of pump builders around here, that I know of.

HawaiianJet,

Be prepaired for Rondane to slam this post again! LOL

Duane Oblancer @ Hi-tech Performance has shoe blanks which he could sell you. Machining the intake is not much of a job. I'd give him a call and talk to him about it. 417-858-8616 I'm sure he would be happy to explain how to machine your intake to accept the shoe, however there are some finer points to it which in my opinion would be better left to someone who does it everyday. The shoes are a raw aluminum casting, so they will have to be machined also. HTP is in Shell Knob Missouri, so not far from you. Turn around shoud be quick if you decide you don't have time to do it.

Possibly there is another shop closer to you, but I'm not aware of them.

Also, on setting your intake, I would advise taking some measurements, and checking the angle of the intake in relation to the keel rather than depending on the idea that it was set right when the boat was built. More often than not it was off when the boat was built. I'll bet if you get to measuring, you will find that the stringers are off side to side, and the intake probably is too.
Most importantly though is the angle that the intake is set at in relation to the keel. I definatly would make sure it's right before you set it in epoxy!

Hope this helps,

Ken

Duane is the guy at HTP, which is Hi-Tech Performance, right? And who the hell is Rondane? Why is he so pissed off? Still not sure if I want to take the time to do the ride plate thing. You guys haven't convinced me that I need it or told me what the advantages of the the ride plate are. I don't have the money right now to do something that is not going to help me go faster or ride better. I'm a poor college student. Need stats on the ride plate set-ups please.

That means I have to get my boat level front to back and side to side, right. Then measure all the angles in relation to each other, right. Shouldn't be too difficult. It's not like it's rocket science. Thanks for the advice, I will definitely check my measurements.

Dammit, I'm talking about setting my intake on my ride plate thread. They're all starting to run together into one big thread.

Thanks everyone. Keep it going. Keep bringing in the suggestions.:)

Call Duane
That's what everyone keeps telling me. I will, I will. I wish to someday have a reputation like that. Ask 3 different questions and get referred to the same person for answers, by multiple people on the opposite side of the country. That's really saying something dude.:)devil

HJ,

Nobody really knows WHO rondane is, but for some reason really has a woodie for Duane who owns Hi-tech Performance. Duane is one of probably the 2-3 best pump people in the U.S., and is one of those guys who LOVES jet-boats! He invented the ultimate wear-ring, the Jet-a-way, the Save a Jet, the new Hi-Helix impeller, just to name a few. Back during the days of Hotboat forums rondane would jump in any thread where Duane was mentioned and really slam him or/and his products., turning most threads into garbage as people responded to his negativity. This seems to be starting over here also. If you were to do a search for all of his posts, I would bet that 98% would be negative. Duane is really the only builder who will come on and answer questions for people just to help them out. I just built their new shop in Shell Knob, MO and was amazed at the amount of the day that Duane spent on the phone just talking to people, giving advice & trying to help.

OK, on to bigger and better things....Rideplate advantages-

Imagine your boat going through the water from underneath the surface.
It's up on plane, and there is still a certain amount of the rear of the boat in the water. Water causes a GREAT amount of drag, thus inhibiting your forward motion with X amount of power.

Now, add a ride plate which extends 20" past the end of your boat. The boat is able to "rear" back on the rideplate and free up "wetted surface" of your hull. Bingo-less friction, and consequently more speed. The rideplate can also be adjusted w/shims for angle to help "tune" the boats ride angle.
This is why people who are really serious about going fast usually set their pumps back so that the hand clean-out hole is outside the transom. This extends the rideplate further making the boat "think" it is longer than it actually is. So now, instead of having 7' of boat in the water on plane, you now have only 2-3'. Less drag, faster speeds. Make sense?

Now to the shoe on the front of the rideplate. This obviously "scoops" water or takes a "bite" of water to direct water into your pump. Not getting enough to where you are experiencing cavitation? shim the shoe down, let it take a bigger "bite" of water. Getting too much, where your intake pressure is too high? Mill a little off your shoe so it doesn't take such a big "bite". In a couple of years (after you've decided that you are no longer happy with your truck engine, and start turning it into a race engine) when you start looking for more speed, now you have a tuneable intake already on your boat.

Now. I've seen your kind before. I used to be just like you. You are learning about your boat, and loving every minute of it. You are already addicted. Stand up and say: "Hello, my name is HJ, and I'm a jetboataholic."
You are going to want to go fast. Your first year you will get your boat running and on the water. You will be thrilled and elated at how fast it accelerates. You will love running across the lake at 60 mph and hearing that big block behind you, echoing off the hills, and people being in awe.
You are no different than all of us on here. Install your rideplate, cause you are going to need it next year! You ARE going to want to go faster! LOL

Hope this helps,

Ken

Hello, my name is HJ, and I'm a jetboataholic.:D

Lots of great information here, really appreciate all the advice I'm getting. Makes perfect sense. It just pushes the back of the boat back 20" or so, right. Making my 19' boat into a 20'+ boat.

But, I've got another question. While plowing around on the internet, I came across something called an Adapt A Shoe. It bolts directly to a stock Berkeley intake without any machining. Does anybody know anything about these? Because this sounds like a real attractive set-up for my situation. I found it at ARS Marine they're who I bought the intake epoxy from. If I could possibly get just the shoe from him, then it sounds like a winner for my situation.
Thank You.

And that is a long winded post, but it's a good. I enjoy reading all of this and responding to all of the messages.



Hey mike t. Those are some odd looking headers. What is going on there with them? I really like them. What kind are they?

No Grasshopper.....you're not listening. Wax on........Wax off........

Those are made for people who still have their intake in the boat. It's about half a bandaid type fix. You have your intake in hand, machine it off and do it right the first time around.
