    Default jack plate?

    My 16'ft skiff has a 25hp Evinrude with a prop and whale tail set up to prevent cavitating. It works ok, but I'm not impressed with it's performance. Anyone know where I can get a jack plate to lower the prop another inch or so in the water? I haven't come across a jet unit deal yet so I'm trying the jack plate idea.

    First where in relation is your cavitation plate to the bottom of the boat? I've got a hydrofoil on my Merc 25 prop, and it does great, pops up on plane instantly. My plate is about 1/2" below the bottom. Now for a jack plate you have bobsmachine.com or another one I saw was tsgcustom.com.

    Mine is about 1/4 inch above the bottom. The transom has already been cut a couple of inches down so I don't want to go any lower. Does your boat get squirrly when running full throttle? I saw those websites but I was hoping to find someone local. Thanks for the input.

    There are not alot of guys here in southcentral that deal with jack plates. I had the best success by talking to and dealing with a place in petersburg. Rocky's marine.
    Alot of guys down there use them and know alot about them. The one I have on my boat allows me to change out the lower unit and either run the prop or the jet unit.

    Outboard Jet makes a transom mount that provides adjustment range to switch back and forth from jet to prop or anywhere in between. Dewey's usually has them in stock. I believe the plate has 8" of travel. I like mine!

    I see there is still an ad for a manual one in yesterdays postings.

    No, my boat doesn't get squirrly, but I did put a piece of 2x4 under the motor to act as a spacer between the top of the transom to see if I would benefit any with a jackplate and noticed that it did get squirrly then. It also got harder to steer (tiller). My cav plate ended up being about a 1/2" above the bottom of boat. With my lower unit being around 11" long that spacer didn't help much at all. So now I looking into a outboard jet for the river.
