A jack plate will compensate for a long shaft engine! Does Your Boat Need a Jack plate? For this one, we consulted our network of industry professionals. Their responses were all varying degrees of a resounding YES. But how can you tell if your boat would benefit from a jack plate? What are some of the symptoms? Poor HoleshotYour outboard’s not perpendicular (straight up & down) in relation to the water at top speed.If you can trim the engine all the way up without the prop letting go or with no appreciable loss of water pressure at full throttle.The hull doesn’t seem to “lift” like it should.Boats rigged with jack plates, but otherwise identical to yours, turn higher-pitch props and perform better keep in mind that these characteristics can also be indications of other, more serious problems, but if you’re experiencing any or all of the above, your boat could be a good candidate for a jackplate implant. Jack Plates are the perfect solution for long shaft engines with a short shaft transom! The engine side holes of the Jack Plate are drilled 1.500 inches higher than the transom side. Combined with the 6 inches of adjustable vertical lift you can obtain 5.500 inches at a maximum height to raise your long shaft engine and make it workable on a short shaft transom boat!Here are the pre-drilled hole dimensions listed below in inches: Pre-drilled holes for 1/2'' stainless hardware12 7/8'' across the top two holes from center to center9 7/8'' across the bottom two holes from center to center8'' of vertical distance between the top holes and bottom mounting holesIf your holes do not match this configuration, you can drill into the aluminum plate. However, by modifying the unit returns will not be accepted. ## Features - 【High-Quality Material】-Made of high strength polished Aircraft Quality Aluminum - 【ADJUSTMENT]-Offers 6 inches of adjustable Vertical movement - 【FEATURE】-A jack plate will compensate for a long shaft engine - 【WEIGHT】-The Manual Jack plate weighs 27 lbs, light and easily installation - 【INSTALLATION】- Professional installation is highly recommended. ** Instructions NOT included.** Provide technical support at any time.

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! ### ⭐⭐⭐⭐⭐ Quality made *by H***S on August 18, 2025* Seems to be quality built.
