Best Manual Jackplate

Vandalizer

Well-known member
I'm looking at an Exciter, but it doesn't currently have a jackplate. I think I'd like to stick with a manual jackplate to save weight and $$, but only if it's something I can adjust fairly quickly on the water. I've come across a few CMC's that purport to do this, but their website is poor at best.

I'm completely new to the world of jackplates, so any suggestions on setback amount are very welcome. Also, do certain jp's have mounting layouts that will work with existing transom holes?

Thanks all!

I don't understand what you're getting at here... Cavitation plate?

What type is yours, and how much do you want to get rid of it for?
 
Well sorry about the gigantic picture. I cut and pasted that one from the ByuBoyz forums "For Sale" section. The 14" Rapid Jack is for sale there. A cavitation plate is the solid plate that closes off the bottem of the assembly. It keeps water from piling up inside of the jack plate while planning off and cuasing drag. Nice addition to any "big" plate.

I have a 9.5" maual plate like this.

I would sell it if I could make a deal with the other guy. I'd take $150.00 for it. It works well, but I'd like to try more setback....12"-14".

You might just consider the Rapid Jack I linked to. That was my original intent since funds for a $300.00 jack plate are not readily available. Then again, it'd be hard for me to pass up on for a net cost of $150.00 by selling mine.
 
i have a cmc 12" on my starflite and will say this-

THE CMC STARTS WAY HIGHER THAN ANY OTHER JACKPLATE!!!!!
i don't care what anyone says this plate/setback is by far the highest starting jackplate i have found! when i say this i am talking about from where the motor was mounted to where it is after installed. do some research and you will find out that the CMC is actually about 1.5" inches above(at the lowest point)any other jackplate you will find.....

i know i will get a response out of this one:popcorn:

TOP for that boat all you need is a 6 inch jack plate. Thats what my V-mate II had, made a HUGE difference. Anything more on that boat and you will be asking to destroy the transom.
 
I've owned a couple CMC jack plates and a RapidJack HD jack plate. Both good units for sure. As far as saving time, the RapidJack might be a few seconds quicker to adjust than the CMC.

Ney Nerd. There's a BIG difference in a V-mate II and an Exciter. Both weight and length. Don't think they are a good combo to compare setups. 6" of setback may be right for the V-mate II like it is on a Predictor. IMHO and experience from owning an Exciter, a 6" jackplate is NOT enough for the 18' hull. The 9.5" works well, but I still find myself using an awful lot of trim (all of the up range) to obtain maximum RPM. That's why I want to try more setback. Not sure how your Predictor was setup from Checkmate, but the Exciter has a transom Knee set and if it's in good shape up to 10" should be no problem. Mine, of course has been redone and is structurally sound. I don't think there will be a probem with more setback. You see guys here looking for maximum performance on 21' Starflight hulls going with 12" or more of setback successfully. It may be that 10"-12" is the right amount for an Exciter. I don't know. I haven't seen anybody else experiment with setback on one, though. Me, I would try that 14" in a minute. I think it would work.
 
8-10' is probably in the ballpark for an Exciter. That 235 is a fairly heavy motor too which factors in. I like the Detwiler manual plate. It is very sturdy and well built. They used to make a single screw adjustment version that you might be able to find. The regular one only takes a minute more to adjust. The downside is they only have a range of 3.5" in height. You just need to mount the motor in the right place for starters and it is fine.
The Slidemaster is similarly built and has more adjustment.
I'm not a fan of the CMC...but others like it.
The Rapidjack is supposed to be good but I have never had one.
Bassboatcentral.com always has used JP's on their forum for sale.
 
I must have someting other than an Exciter becuase whatever Checkmate it is I own wants more than 10" setback...
 
Point taken...you should know. :thumb:
At a certain point too much setback starts having negative side effects. 14" on an Exciter will probably cause it to porpoise in the mid range. It would be interesting to see what it would do on the top end.
I reduced my setback from 13" to 11" on my Starliner because of porpoising and the extra setback didn't give me more speed anyway. I'd likely need 15-16" for more top end but I was not willing to compromise handling...not to mention the transom.
 
You make a vild point, Mark. I am, in fact, concerned with 14" being good for nothing other than top end, as well. I don't have an issue with porposing now and don't I would prefer not having any. I do know 10" of setback, however, is not quite enough as I have to max out my trim. I think the boat would handle better...with having to use less trim...which is one benefit from running the proper amount of setback as I understand it. 12" may be the number. Would kind of make sense that 10"-12" would be about right for the 18' Ecxiters since the 21' footers like the Starflites, Pulsares, etc. are running anywhere from 12"-15" (Jupiter Pulsare).

I don't know what a 235 weighs, but it may be too much to hang 14" off a transom. Especially on a older boat that may have some rot issues going on. I will say that I got my Exciter with a 10" "extension" bracket that the previous owner had ran with a V6. The transom had no signs of cracking and the transom was the only thing that wasn't rotted. The floor, stringer(s), and transoim knees had rot damage and it still held a v6 up on a 10" extension with no issues. I have no concern about it's ability to hold a V6 on a 10" now since I've redone everything. I wouldn't have any concerns with a 14" even....on my boat, anyway.

In summary, you say 8-10" is ballpark and I will partially agree. I say 10-12". So it would appear that we are both "in the ballpark". :thumb:
 
Thanks guys, helpful stuff.
There's actually two different Exciters that I'm looking at- one's a '79 with the 235 rude, the other's an '87 with a 175 black max. The '87 has a non-functioning hydraulic jackplate on it right now, looks like it has very little setback though- it may only need a new pump to get it working. I'll be taking a look at the '87 tonight... we'll see where it goes from there.

Thanks for trying to call me out and letting me know the differences in the two models, I thought all Checkmates were the same.
 
In 1978 the V-mate II wieghed in at 810 pounds.
In 1980 the Enticer wieghed in at approx. 800 pounds.
