outboard height, the right or wrong way

Hi All,

I have been rebuilding a 6-meter fibreglass boat off and on over the last four years, and I am nearly there. I have just purchased a Suzuki DF140 to mount onto the pod that is fitted. I read in this forum that you should raise the cavitation plate 1” for every 12” of set back, so I got that part covered, but how do you measure it.
Do you measure it with the cavitation plate set parallel with the hull or with the motor trimmed in or out ????. Anyone go any drawings or a solution.
I searched this forum without a lot of success, anyone got a solution.

Regards
Bruce

 

Parallel

This is what I have got to offer, hope it will help a little.

Thanks Guy's,

Setting the height with the cavitation plate parallel seemed the only way, but you never knows sometimes.

bruice
i would check with the builder
i have heard that bracketed outboards can be raised an amount per ft
as you first thought

 

even if it is raised...it still should be parallel.

Parallel. Start with a figure representing the motor mounted directly to the transom and the cav plate EVEN with the bottom of the hull. Then as per distance of setback in inches, raise the motor in reccomended distance. Say the setback is 18", then the plate sers 1 1/2" above the bottom of hull in full "down position, BUT still parsllel to transom
My jackplate (which is hyd adjustable) set my motor back 6" so I set the motor 1/2" above my hull bottom when the plate is totally down. Then I still have "trim" left to micro manage. I also can raise mine on the fly.

 

yep. i had a mental hickup
i read it as doing the rise or keeping it parallel/level with the keel line, my mistake
