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? Your outboards 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 doesnt 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 youre experiencing any or all of the above, your boat could be a good candidate for a jack plate implant. Review from 2006 Bass & Walleye Boats Magazine. This Jack Plate is designed for smaller motors to improve the performance of your boat. Two pairs of precision machined aluminum angles locate the motor with 6 setback from the transom. Slots in the angles allow 4 of vertical movement to position the motor in the correct location for maximum output. Stainless steel bolts hold the angles in place.
This Jack Plate is rated for motors up to 150 hp and comes in an attractive polished aluminum finish. Fits all V-4 and V-6 standard bolt pattern engines.
Some special drilling of holes may be required on engines manufactured before 1980, the pre-drilled bolt pattern is listed below. Cost 30% less than from a Dealer! Made of high strength polished Aircraft Quality Aluminum. Offers 4 inches of adjustable Vertical movement.
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 4 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 hardware. 12 7/8'' across the top two holes from center to center.9 7/8'' across the bottom two holes from center to center. 8'' of vertical distance between the top holes and bottom mounting holes.
