Wanaflatsfish Posted January 30, 2017 Report Share Posted January 30, 2017 Please provide comments.... I have seen quite a few on the various for sale...some say yes, others, no.... dc Link to comment Share on other sites More sharing options...
conocean Posted January 30, 2017 Report Share Posted January 30, 2017 NO. You can find plenty of porpoise all over the ENP! Link to comment Share on other sites More sharing options...
DaveC Posted January 30, 2017 Report Share Posted January 30, 2017 I didn't add one, I did change the trim tab size to 12"x12", I believe that I'll be able to use less down angle on the tabs to eliminate (reduce?) porpoise and keep the CG at an optimum position. We'll see? Link to comment Share on other sites More sharing options...
FLDXT Posted January 30, 2017 Report Share Posted January 30, 2017 I've always heard no, I don't have one, never ran one so don't have alot of.valuable insight. Never felt like I needed one though. Link to comment Share on other sites More sharing options...
hurricane Posted January 30, 2017 Report Share Posted January 30, 2017 I would lean towards no. Mostly because I think to take advantage of a jackplate on any boat it has to be atleast 6", anything less like 4" is not enough to allow the motor to run higher. But then, when you move the motor back 6" I think you loose draft and need more tabs. I have no experience with a jackplate on a 17, so that's all just a thought. Might be worth a try, if you find a used one you could turn and sell with little loss if it doesn't work out. Link to comment Share on other sites More sharing options...
Wanaflatsfish Posted January 30, 2017 Author Report Share Posted January 30, 2017 I remember Buttapolka had one...but, I guess the group think is a definate no... thanks... dc Link to comment Share on other sites More sharing options...
Lap it Up Posted January 30, 2017 Report Share Posted January 30, 2017 Buttapollack (however that's spelled, sorry😁) ran one and has lots of knowledge. I personally wouldn't own a flats boat or bay boat without a plate. Technical poling skiff is different. Link to comment Share on other sites More sharing options...

I'm concerned about the porposing.....I do like the ability to raise the lower unit out of the water.... Toying with the idea as Bob has one for sale...but, Momma is telling me....Ya-basta on the $$$ for da bote dc Link to comment Share on other sites More sharing options...

All the MA's are known to porpoise with the wrong mix of tab. I was able to raise my old Merc's lower unit out of the water without a jp. Link to comment Share on other sites More sharing options...
Lap it Up Posted January 30, 2017 Report Share Posted January 30, 2017 idling trimmed up with prop in the air and idling quietly with prop underwater is different. Also with a little tab you can pop up with the plate all the way up. Adds a whole different element to spinning up in shallow water. Porpoising can be fixed with the correct prop.

I was able to raise my old Merc's lower unit out of the water without a jp. Yes, more of what Lap it up was referring; however, thinking out loud....with the new Ulterra 80, I have found myself not idling in and out of fishing spots, but, rather, using the TM to get into a spot - again, I normally stop 75-80 yards out and ease in while I"m rigging the rods from the bote.

pondfisher Posted February 6, 2017 Report Share Posted February 6, 2017 I say No. So will Skip. Although Robert (buttapollock) and others claim to have different results. I added one to my 17 and learned the expensive way that it does not serve the primary purpose of allowing you to run skinnier. I have a Bob's JP with a 4" setback and if you raise it up past the 3" mark on the plate the boat will both porpoise and cavitate like crazy. I added 5 degree negative wedges and they help with the hole shot and a little bit to help running with the plate up but there's just something about the hull design on the 17 that does not allow you to raise the plate up all the way to it's furthest height (6") without losing bite. So for raising that plate up all the way in order to run through some skinny water, forget it.... you're better off just keeping the plate all the way down and trimming up as high as you can to run skinny - that's what I've learned to do (which is what you'd do if you didn't have the JP in the first place). And if you think you're going to be able to raise that plate all the way up for a hole shot in shallow water, forget it... won't happen. You'll see porpoising like never before. It will be like riding a bucking bronco at the rodeo. What I do like about the plate is that it allows you to idle around in shallow water looking for bait, getting close to the beach, etc., just those times when you want to move around slowly in shallow water but do not necessarily need the stealth of the trolling motor. But that's about it. Link to comment Share on other sites More sharing options...

Excellent report....yes, looks like my Ulterra 80 will be running alot looking for the bait and moving into the bights.... dc Link to comment Share on other sites More sharing options...
conocean Posted February 7, 2017 Report Share Posted February 7, 2017 It won't matter IF you install the Stealth AC/DC charging system because you will have fully charged batteries after every 30 minute run on the two smoker! Link to comment Share on other sites More sharing options...

Mitz Posted March 11, 2017 Report Share Posted March 11, 2017 I say why not. That hull can hold a lot more weight than these light v4's. switch to a 4 blade prop and try a 6 inch set back or the 5.5 from cmc. I added a CMC to my 02 18.5 w 175 hpdi.... including and extra .5 set back from the powerpole bracket for a total of 6 inches and wish i would have added it sooner than 2 months before i sold the boat. ran awesome! I would def try one on the 17. didn't sit noticeably different at all or really porpoise anymore then it already did w/o the jp. 1st is without jp, rest are with...
