I need to get an idea how long I should make my ride plate. I looked in the old threads but couldnt find anything :-\ . In the pic the end of the tape measure is at the back of the shoe.

I'll measure mine tomorrow and let yah know my dimensions
-
;D Thank you kind sr.
-
18" is a good starting point but you may end up ± depending on what the boat wants
-
Propless, like Josh said, the typical rideplate is about 18" long. From your pic, however, it looks like you may be measuring from a point further forward than the step on the back of a typical shoe. You should post a pic of what you have for a shoe. Important thing to remember, it's easier to start too long and trim it, than it is to start too short and make it longer. :D
-
Thanks guys, heres a shot of the shoe ??? . I just went out and measured again, and the other pic is correct, there is 20" from the front of the shoe notch (where the plate mounts) to the center of the steering pins. I dont want to hear this is wrong and I need to pull the intake !!!! :sly:

Dont know if this matters or not but I have an old style (looong) diverter.

Propless, the shoe looks just right. Perhaps the fact you were measuring against a "C" bowl ,not a split, is what made it look off.
There is a guy on Performance Boats that could use pictures of the reverse cable bracket for that old long diverter. All he currently has is that long nozzle and matching reverse bucket and is trying to figure out how to make it all work. One of his options is to modify the "current" reverse cable bracket to the early configuration.

Thats good news. ;D I guess I'll have Ironman cut me one at 19" and start there. btw , what would happen if its to long / short, just so I know when tuning time comes ?

I just posted some pics for him, always willing to help. ;)

I gave up on that quest now, and just said F'it and bought a brand spankin' new PD (and I had the ball too, I had everything but the 2 damn brackets).
What's the progress on this? Did you ever get it made up? How did it turn out?
I would cut it at a nice, even 20" and go from there. Don't forget to put stiffening bars on there, so the plate won't flex, when the boat is riding on it. ;)
-
Nice to see you made it over here, Welcome ;) .

Progress is going slow but its getting there, plate and supports should be cut soon, the project thread is here http://www.socaljetboats.com/index.php?topic=3365.0 , it wanders a bit ( in typical So Cal fashion ::) ) but its all good ;D .

Yeah, PB's been a little slow, being July 4th weekend, so I've been reading some of the crap over here. Since, my boat's not in the water and it's not dark yet! :banghead:
I didn't read all of that thread, but I looked at all the pictures and read what went along with the pictures. Looks like you've been working your ass off on that thing. It's looking good. Now just ditch the Ford! ;D

It's wrong and you need to pull the intake. There I said it. ;D ;D ;D

Curious about using a "C" bowl with a ride plate. How do you support the back of the plate off the bowl? There is no extension to the bowl where you can drill and tap for a cradle and no flange to allow you to use turn buckles... you're also stuck with the thrust height.
-
ahhhhh, i was thinking the same thing..

My bowl is also drilled to accept this cradle (2 set screws on either side of pin). Unfortunately, I don't know if this is factory for my bowl, or if some one just drilled them because I do not have that cradle or a ride plate.

Thanks for the pix I never knew such a piece existed. It still doesn't fix the biggest problem of thrust height which you can only fix with a droop snoot. But if your not racing, go for it. it's a lot better than the cost of a JG or JR bowl
-
Just a reminder here. Not every boat needs a droop to work right. It was recommended to me by Greg Shoemaker not to use a droop on this hull, and since the JC is said to flow better than the split bowls, I'm sticking with it for now. Although I may need to change to a split bowl later if it needs some wedge.

You could always have your JC bowl converted, and keep the flow advantage of the JC bowl, but have the adaptability of the JG bowl.

While sitting in the garage looking at the pile of spare parts, and being really mad about my alt mounting (don't ask :mad: :mad:). I had an idea :o ::) . What do you guys think about this to adjust the ride plate ???
I was thinking about using longer bolts for the 2 outer bowl to suction housing bolts and adding a bracket there to mount these old cav plate adjusters.
[attachimg=1]
It puts the adjusters at an angle (not sure about that), but they would be at opposite angles kinda like this \ / . here's another shot . What do you guys think, will it be strong enough ???
[attachimg=2]
-
Can you move the buckles so they can mount to a flange that bolts to the split bowl? Look at 2sav's boat, seems like a sweet set up
-
No such luck :'( , it's a JC pump (for now). :)

I know You don't want hear this but i think a split bowl will open up a whole bunch of avenues for you to work with ???

Someday when I'm rich like you I'll have one, but for now this has to do . ;)
So does anybody see a problem with the adjusters mounted like that ??

Sorry bro, didn't mean nothing by that.... I understand where you are coming from. Believe me ;)

I think your on the right track Jeff. The fact that the turn buckles will be \ / shouldn't be a problem. I'd also suggest adding some stiffeners to the rideplate, as you have more of a potential for flex with turn buckles than you do with a fixed yoke.
edit: I may change my opinion if the angle on the turnbuck is past center
-
This may give you a few other ideas, its an E pump cav plate adjuster

I actually used that same piece on an early setup on the little boat, retrospectivly I would have added stiffeners like I mentioned above

:o :o 2sav being nice to a Ford guy ??? ???. Alright bro whats up , no anti Ford comment, no little Chevy's rule comment, Are you feeling OK ???. Did you break/sell your motor again ??
edit: I may change my opinion if the angle on the turnbuck is past center
Ok, Josh . You got me on that one, what do you mean " if the angle on the turnbuck is past center " . This is kinda what I had in mind ??? .

Propless, you can drill into the JC bowl a little ahead of the narrow point and mount adjusting links there. The process of locating the points was explained to me several years ago by Jack at MPD. I ended up finding a split bowl before I drilled my C bowl. I seriously recommend calling him for the information as the setup you are contemplating lacks much strength due to the severe angles. You really want the mounts on the plate very close to the end.
-
Thanks for the info Oldsquirt ;D . Maybe I'll end up going with a split bowl before I drill holes in this thing too (its only money :-\ ) .
-
Hey Propless
Lookin' good--when will you be ready to go to the lake? I know that most Sanger Jets came with the distinctive round transom cover and a short 4" or so ride plate that was braced to the transom with turnbuckles like you have suggested. Probably not as much leverage as your application, but personally, I think it would look pretty clean. Probably would need stiffeners for the ride plate.
Let me know when you're going boating.

Or you could use one of these and drill two small taped holes in the bowl at the neck and be done with it. Just give Duane at HTP a call and be done with it. Simple 10 minute job (once you have the cradle, of course) ;D

propyou need to support the plate further back or with speedit will constantly change angle depending how fast you are going not safe some of my friends on their drag boats have something similar to real hawaiians its just smaller

I was thinkin the same thing . Most of the plates that I've seen , have the support at the furthest point back .

You might not be pushing it fast enough for it to matter though . I dont really know if it matters in your case . The HTP piece looks like your best bet and it mounts in the ideal spot . I'm almost willing to bet that that will be excactly where the plate will end too. The only thing I dont like about turnbuckles is when adjusting them , you never really know if your level . With the saddle type , you can add or subract shims as needed . Just my preference and view though . Your kickin some ass Jeff.
