Jack Plate JPL4500 Manual Jack Plate Adjustable 6" Outboard Motor Jack Plate for Boat Steering System

I’m writing a review because none of these other reviews answered the questions I had when I ordered it.1. This is a very nice jack plate. It’s very high quality and exactly like Vance marine jack plates.2. It can fit smaller clamp on outboards but requires small adjustments. I had to add spacer shims for the lower motor mounts as shown in the pictures which is just some aluminum flat bar from the hardware store. And I had to drill holes in the outboard mounting plate of the jack plate to get my 30 yamaha on it but it wasn’t hard.3. If you’re mounting a smaller motor on the 4” jack plate it’s a little tight getting to the adjustment bolts and nuts on the center shaft that lifts the plates. The fine thread does lift the motor with ease. So take into consideration the height you set the plate before you put the motor on. You can adjust it after but it’s not as easy.4. This jack plate helped my top end and handling TREMENDOUSLY. I gained 8mph in the top end and had a much better hole shot having the setback to put my prop in less turbulent water behind my boat.5. This jack plate allowed me to run much bigger pitch props as well.6. I hit 2 logs with my scag on my boat and the plate didn’t even budge so it’s pretty dang sturdy and strong.All in all this is a great product I’m very happy with it and it makes my boat perform and look better 5 star product in my books!

Seems to work. Haven’t had it on the water yet. Really sturdy built. Seems to be a great value.

Really solid and easy to adjust.

Very good quality

Put a 150 merc on a 17ft Lund and got 6.5 inches of lift on the bottom bolt hole(on the motor) all I did was take a step bit to it and made the side bolt holes bigger for the .5 inch but it works good don’t listen to the other whiny people they expect plug and play when it comes to boats.

Why did you pick this product vs others?:I attempted to adjust the jack plate before installing it. The aluminum adjustbnut stripped. There is no way to adjust it while the motor is mounted. Junk.

I mounted it on my jon boat and it has a 25 4 stroke sitting on it. Adjusted easy and has held strong

Doesn’t fit mercury tower of power outboards. Had to cut it so it fit
