update!
The mercruiser outdrive has a pinion gear that reverses the rotational direction, I was surprised that I was required to remove and turn the engine and hybrid transmission around for correct rotation.

( yes I thought of this first, and yes I have tried both the cw and ccw outdrives) there was no other way.
I installed a keel cooler after the first float test, a 12 inch square Heater core mounted to the outside of the transom.
this has performed remarkably well, bringing engine temp down from 107C to 79C
top speed was limited by the toyota traction control , my solution was to install wheel speed sensors to the axle at the original location by the magnetic toothed ring.
Toyota Electric Power Steering has been installed with sluggish results, quicker response to the steering wheel torque sensor is needed.
the second float test has resulted in speeds perhaps around 10mph,
about twice as fast as a Honda jet ski idles.
