Also allows mounting of long shaft motors to shorter shaft transom boats
This cast aluminum offset type jack plate is designed for clamp-on mount outboard motors up to 35 HP. Improves performance and handling of smaller or lighter boats. The Mini-Jacker also allows mounting of long shaft motors to shorter shaft transom boats. Mini-Jacker mounts to boat transom with bolts and then engine is simply clamped and/or bolted on. The Mini-Jacker stands off transom 4". The engine mounting surface is 11-1/2"Wx10"H and features a vertical offset of 3". The overall width of transom mounting flange is 17". Mounting hardware not included.

Product would be great if it raised the motor the full 5" that is needed to put a long shaft on a 15" hull.
Had to a spacer piece made to make up the difference. Had I known this in advance i would have had the whole Jack Plate shop made. Beware!!~

Rated 5 out of 5 by rdmrkelly Perfectly affordable simple solution
Simple straight forward solution to a problem. Super value. Mounted it on my 16’ flat bottom. For the cost it is not worth trying to rig up something on your own. You need to drill six 3/8” holes in the unit and then in your boat. Make sure that you have the unit high enough on your transom to give clearance to be able to rotate the clamp dogs on your boat motor. I got min about an 1/8” to low and had to put a shim under the motor. My son and I had it mounted and ready to go in about an hour. Make sure you seal all holes. I also put a couple of coats of spar polyurethane on the plywood block. I found it to work great. Boat planes out much better with no water spray now. Definitely a winner.

Rated 3 out of 5 by shep79 mini jacker...had to return
I mounted the mini jacker on a 2010 klamath 14' deluxe. I had to modify the plywood on back of transom. The verticle offset was enough to put the total hight at 20". My long shaft motor was actually 23" to cavitation plate. The bracket is made VERY well, sturdy and thick. I tried the motor at the hight of the mini jacker. it was too low and lots of spray off the lower unit of motor. There was a pop/clunk sound as the throttle was increased on the motor. The transom was flexing and poping like a soda can being squeeezed in your hand.
I consulted with a local machine shop and had them weld a different bracket all together that covered the entire transom. Motor hight is perfect now. NO popping, planes easily. The cost of the welding was 40.00. I cut and fit the aluminum pieces myself.
I returned the mini jacker to Bass Pro. Good customer service. I gave 3 stars because the bracket seemed to be made well, but not for my klamath.

Awesome product. I used it on my Tracker 1648 to get my jet set up at the right height wroked perfect and you cant beat the price.

Thinking of picking this up to use as a kicker mount for our 18' Four Winns. Description says it has a 4" clearance which would be great since I'd have to install where the tie down is. I'd keep the tie down in place and just reach under to tie it down at the end of the day. Anyone else use it as a kicker mount?
The important factor is the distance the cavitation plate is below your boat. mine is 1/4 inch. If you rase your motor too high, you will cavitate and over heat/burn up motor. put a straight edge on your cavitation plate of your motor and measure to bottom of your boat.
I have a 16', 52" bottom alumacraft with a new 2009 mercury 25HP fourstroke, longshaft. Will this minijacker lift my motor too high, causing cavitation? I fish shallow marsh and could stand to run a little shallower. I would buy this jack plate if I knew that the L/D was not excessive for my boat. PLease advise.
It raises the height 3". I mounted mine 2" above the top of the transom and added a piece of 2"x2" square tubing onto the transom so I would have something for the top bolts to mount to. I used a total of 8 3/8" bolts and it solid. it works perfect for gaining the 5" although the instructions recommend mounting it no higher than the top of the transom.
It will raise it at least 4". You could go 5 and likely 6t if you mount the top of the mounting plates above the transom top. To do to this, you need to have a flat transom. Some aluminum boats have a lip on top of the transom, that make this difficult, unless you shim the mounting plate, which would work fine, but would take a bit more finesse to install than just bolting it on.
This thing is solid. I mounted a 15 HP long shaft on it that was at least 110 lbs. It is rated for a 35 hp and seems likely to easily take that. I think it is a bit over enginered and would easily take that, as long as you bolted it on adequately with quality hardware.
No, I own one and if you try mounting it lower on the transom then the vertical offset portion of the mount will be too low to allow the outboard motor clamps to clear the space between the transom and the mount. I've seen welding shops cut a small portion out of the transom, re-seal, then mount a short shaft on a long shaft transom. Locally, $150.
Yes, the mount comes with no pre-drilled holes. The indentations you see are starter spots to drill through so that the mount is very adaptable to many boat applications. You can mount with 4,6,8 or whatever amount of bolts you desire by drilling.
Not likely. This will add about 4" in transom height.... 18" is likely a small HP short shaft, which is designed to go on a 15" transom. You could mount it lower on the transom, so the top is 2" below the transom, but it would be hard to get to the mounting screws on the outboard as the transom would be in the way.
