Anyone ever consider putting a 6" jackplate on a walley rig.

...and most aluminum walleye rigs carry the bow well when maxed out on power, hence jack plates are not common. Some glass hulls and modified bass boat hulls used for walleye fishing do not carry the bow very high without excessive trim- and jackplates are often used to fix this. A second problem on aluminum rigs is finding enough stiffeners in the transom to take the higher hull loads imposed by the plate. The last issue is when the rig is to be used for trolling, since the motor on the plate tends to be buried in the water unless you run a hydraulic plate and raise the motor up while trolling or drifting in rough water.

I have a 4" manual jackplate on my 1999 1700 prosport. It was kind of a dog as the gas tank is mounted above ****pit level in the bow. Add in a couple of trojans under the consoles, and a trolling motor, and the prop just couldn't get the bow up. My boat is rated for 115HP, and I asked the dealer if I could put a 500 pound Honda 115 and a kicker on it. He said that would be fine, so I put a 360 pound yamaha 115 and no kicker. I'm no physics expert, but I would bet the Honda combo would put more stress on the transom than what I did. Got about 5MPH out of it. And no, the engine doesn't sit too low in the water, as I was able to lift it about 2" higher with the setback. the jackplate has now been installed for 7 years, no problems.:smirk:

The reason I ask about adding a jack plate is because I run a 386xf stratos which I believe is the same hull as the 385 and at WOT and trimmed up I will start to blow out the prop in turns and depending on weight load I will blow out while trimming. I have already lowed the motor to its lowest point and was wodering if a jack plate would help this issue by getting the motor in cleaner water behind the boat.

Sounds like you have a prop issue. What motor and prop are you running on that setup? Your prop isn't getting enough bite. The jack plate may help, but a prop would be an easier fix.

Its hard to say. What engine/propellor do you have? What speed/rpm do you run @WOT? How fast and hard are you turning? Without more information, I'm tempted to say start with a different (more cupped and raked SS) prop before going to a jackplate.

The engine is a 150 Hp Yamaha. Dealer put a 13.5 x 23 pitch 3 blade alum prop on it originally. Motor would only twist about 4800rpm with a top speed of about 41 mph and I could only trim about 1/2 way up in a straight line and then it would blow out. I have tried a 13.75 x 21 pitch alum 3 blade and got a little better on rpm but still about the same as the 23 pitch. 1/2 trim before blow out and boat never lifted. Then tried a 14" x 20 pitch 4 blade alum. This gave me a excellent hole shot and did lift the bow some but still could only twist about 5200 rpm and a top speed of 43-44 mph. I now run a 14" x 19 pitch stainless silverado and the motor twists 5500rpm with a top speed of 47.6 mph and depending on weight disribution I can trim all the way up in a straight line. In what I woud call medium turns it will blow out. If I have a heavy load in the boat I will blow out in a straight line just before I trim all the way up.

The prop is your issue... The silverado is meant for I/Os. You need a prop with more cupping and more rake, like the tempest, Powertech Ptc, mercury laser, yamaha pro series, those all would be performance for your boat.
