Need a plate made to raise motor 3" with minimal setback.

[Mr. Demeanor]

I need to raise my motor (already on top mounts) another 3" or so without adding any more setback then possible. I have been told I can have a 3/4" aluminum plate made to extend the height. Any suggestions appreciated.

....a Bob's Machine 4-in-1 convertible MJ-5 jackplate. They can be assembled with only 2.5" of setback, and 6° of negative wedge or no wedge. Another simple and cost effective solution would be a CMC 50012 5" vertical extension. It is designed to add 5" of engine height with very little setback. By shuffling which motor bolt holes you use, that could be 3~3.5" of added height. :cool:

[Mr. Demeanor]

I was looking at both of those on your site as a matter fact. If I call, who should I ask for since you already know what I'm trying to accomplish?

either barb or rick will know that answer..

The 5 inch vertical extension allows the motor to be mounted 5 inches higher than the standard mounting on the transom. It is a must for conversion from a prop to jet drive. Another application includes mounting the 5" vertical extension on the hydraulic Power-Lift to raise the motor higher on shallow running boats that are equipped with tunnel extensions.

Now one trick is to take a 5 or 6 jack plate that has outside the rail adjustments, (ie: Springfield) and invert the engine mount plate.

Hey Mr. Demeanor...I need the same thing. I've never run across one, so I'll likely have to build my own, but I'm thinking a 5/8" - 3/4" thick alum plate, drilled with several positions in 1" increments.

I need to raise my motors, but I'm not sure how much, and I want to figure that out before getting jackplates, so I know what my operating range is.

[STV_Keith]

OK, I guess this was the excuse I needed to get the plate designed up. Mr. Demeanor, are you running a Merc or OMC? I've got the plates designed...I will send the drawings over to my machinist on Monday. Pretty simple, but material is spendy these days.

PM me if you are interested in one or more plates.

[Juggernaut]

hoist the engine off and stick a 2x3 between the engine and transom. center the engine on tbe boat,seal the old holes, and drill for new engine bolts. did the same thing on my searaider with a 50 merc, but i lifted it 1". got 2-3 mph!
and you get no setback, whatsoever

[STV_Keith]

Kinda hard to do when the motors are on brackets Juggernaut.

[Juggernaut]

hmm.. you make a very convincing point:rolleyes: . well, it worked on my smaller engine. i got the engine with the T-handles on the transom. 1980's 50 horse

[STV_Keith]

Got mine done. Built out of 3/4" T-6061 aluminum plate. :)

that MAY be heavy enough...... just dont go doing super mondo huge air with it..

[STV_Keith]

No air man...it's on a 30 footer! :) These are just going to be used to let me move the gearcases up to get an idea of where they want to run. The end result will be a new Stainless Marine bracket with jack plates, knowing where they like to be. :)
