What jackplate do y'all recommend for the 721?

[mswings]

Going with Either merc 250 or sho 250, what Jackplate do y'all recommend. 6",8",10", 12"?

[nightbasser]

10 inch is the best choice

[EdDavisKY]

Most defiantly the Atlas 10" Hyd. JP w/Gauge Is what I had on my last one with a Merc 250XS and also have one now on my present rig with a 250 SHO.
No matter what engine you chose that JP gives you a lot of adaptability for water conditions as well as load.

I had the Atlas 10" hyd on my 721. That is what I will be getting on the 921.

[mswings]

Ok thanks guys!

[bigfish]

10" hydraulic

[Bos Jigs]

10

[Chuck D]

10 inch setback seems to be the number. I don't have one but might!

Question for you that do, can you adjust it while you are running to dial it in?

I had a 10" Bob's on my Ranger and you could but I don't know the Atlas product as I've not tried it out yet. It's at the top of my list from what I read but want to know if you can dial it in/adjust it while running to get that optimum performance?

[benconkin]

Chuck - You can definitely adjust on the run. I do all of the time and it's one of the single best investments I make on my boats. You have a lot more flexibility in changing conditions and it's much easier to adjust for better performance.

[EdDavisKY]

Yes you can adjust it on the run and will go from top to bottom or visa versa in about 8 sec. Would not be without a Hyd JP now and most defiantly the Atlas. Not the first sign of trouble out of either one of them I have had.

[alabamaphoenix]

Chuck, you can adjust while running WOT. Gauge reads consistent, so you can return to favorite settings.

My Atlas will not go up while running, I have to back out of the throttle to make it go up. Am I the only one that is having this issue?

[Josh*]

Nope, you not the only one Clinton, The few I have used did the same thing.
I would personally spend a little extra for the Bobs plate.

[scboatservice]

Thanks, yes so far, I like the bob's plate better. It seems like the plate gets in a bind when it's under a load, I can't even jack it up at 1/2 throttle. This is my first Atlas, so I assumed it may have been defective, and this thread brought up my curiosity.

Every bob's plate I have ran has never had that issue.

[nightbasser]

We have never had a problem raising at full throttle on any of ours but anything made by the hand of man is subject to a number of units not being perfect

[clm6741]

mine wont raise at wot either, but will if I let off of it some.

[EdDavisKY]

Never had a problem with my 10" Atlas Hyd. JP going up or down no matter what speed I am going even @ WOT.

[MarkNY]

I heard you have to keep the slide tubes clean on these Atlas Plates or they will do that. I think someone had mentioned wiping them down with windex

[EdDavisKY]

I wipe mine down with BBS after every trip, might be why I do not have any problems with mine causing me any problems

[Scott McGehee]

Since everyone seems to like the hydro plate, I'll play devil's advocate and say I always run a manual plate. I've always looked at it as one less thing to have to worry about having problems with.

I've never felt like it was worth the extra cost for 1-2 mph.

Having said that, I will say it's nice when you have to idle a long ways. You can raise the plate and idle with the motor trimmed down in shallower water.
