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!

Very good quality

Really solid and easy to adjust.

It is heavy duty for my 40hp Nissan NS40C . I had to drill some holes to mount my motor, that is kinda to be expected on an universal mount. Looks good, motor runs good, helped pick up some speed on my test runs.

I put this on a 1970 17 ft bay boat that I restored to set the 150 V6 two-stroke back a little so I could set it a little higher to get into skinnier water. I once spent 3 hours bashing into four to six footers that were 4 to 6 ft apart while trying to stay on plane like a total jackwagon and the entire boat was just fine afterwards so this is a stout Jack plate.

as shown in picture, the part that goes to the motor was off center. Unfortunately, I didn’t taken it apart to dry test before installing the other part to the boat. No way to get a hold of the MFG, but Amazon is making me whole with a replacement.

Works for what I need. Just check all bolts on the plate and make sure they’ve been tightened. The inner bolts on mine were loose when I received the item. But overall great value

Solid equipment at a good price but adjusment is difficult. requires taking weight off the device and using wood block shake it free otherwise the lifting device would have faile
