Mini-Jacker for Clamp-on Outboards
Just wanted to take a minute to write a review on a really great product. Hoping to help someone like the reviews helped me when purchasing this product. I will start off by saying this is a real simple solution to a common problem. This mini jack plate is super easy to install and very strong. I used this jack plate to mount a long shaft motor on a short shaft transom and was more than pleased. If you have the same issue that I did this is the easiest cheapest fix to your problem.

Maybe not for short shafts...
A simple design and made very well. That's why I gave it 5 stars. That said, it didn't work for me. I have a 14 foot Jon boat with a new Merc 9.9 HP short shaft. Transom height is 15 inches. My new Merc is is close to 17 1/2 inches from the mount to the top of the cav plate so I thought I could raise the motor some with this product so that the cav plate is pretty much even or slightly higher than the bottom of the boat. No such luck. My motor idled fine but would cavitate approaching plane at the lowest possible position this jack could be mounted. If you have a long shaft you are trying to jack on a short transom boat, this is a good choice. No good for raising a short shaft even higher. Get something adjustable or be happy with what you've got. Just watch out for the rocks.

Just the ticket!
I needed something to match a 22 inch motor to a 20 inch transom. When it arrived I was pleasantly surprised to see how stout it was, it is very beefy and strong looking. I drilled it for 6 3/8 inch carriage bolts and filed the holes square to lock them. Although probably not necessary I made some 1/4 inch aluminum plates for the inside of the transom and used large fender washers on the bolts. I sealed everything with 3M 4200. Boat performance and handling is now as it should be. Elegant and effective fix for the poor matchup by the manufacturer/dealer.

This is one of the best products I've ever purchased. I have a 1542 Tracker Jon with a 16.5" transom and a 15HP Yamaha outboard with a 22" long shaft. I bolted this plate on so the top of the mounting flanges that sit against the transom are one bolt hole higher above the top of the transom and the cavitation plate ended up 1.5" below the bottom of the transom. This plate is super heavy duty. It comes with a 1.5" thick plywood mounting board that fits snugly inside the aluminum plate. The plywood came untreated, so I gave it two coats of Thompsons Water Seal. I mounted the plate to the transom with four 3/8" grade 5 bolts, and for security, I drilled out a 5th hole at 1/2" and put a pin lock that you would normally use to lock a trailer coupler to the receiver. That baby ain't going nowhere!
