I have two Hydrodynamics Magnum jackplates for sale.
See http://www.hydrodynamics-usa.com/prod...RAPID_JACK

The custom taller sizing was specifically to run 25" shaft twin engines on my 1984 Outrage 25, which is designed for 20" twins.

10" setback
Magnum rating - up to 300 hp per jackplate
black powder coated
includes skid plate

I ran them all the way up with my Optimax 150s in the highest mounting position and could see the anti-cav motor plates, so height was about perfect raised all they way for my setup.

The cable mechanism makes these very easy to adjust.

Excellent condition - used about two years until I replaced them with a Hermco bracket.

$200 each plus shipping from zip 24014.
