Tech issues to bear in mind...
Those Garrelic are simple Auxiliary Motor Brackets intended to hold/sit an aux motor side of the main or side of the rudder in a sailboat.
If the OP plans to install both motors with a single installation to be steered and throttled with a wheel and a remote box...
I'm experiencing same tech issue when installing my short shaft 30 HP Tohatsu on a 22 inch tall transom. The only possible way to power my 15 footer Rib at a very slow and boring pace is to throttle the grip far enough to a point just before the prop begins to aerate badly. In such condition...
Probably due to a C-19 long unwanted stop, whatever worked well while well greaed might be darn dried now. If so, will need to remove whatever part has been binding, clean well, regrease and install back to work as used to...

If the current transom is 21.1 inches tall a 15 inch short shaft motor won't work well, will sit too high and the motor will achieve excessive prop aeration. Doesn't matter at which trim position you end playing with...

Better ask the car maker if possible to increase the output power of your current electric vehicle, should receive much better straight tech answers...

If you have had a pleasant experience with an OEM Tohatsu primer bulb order just the bulb without the side fittings, if the current Atwood's fitting it's same diam as the Tohatsu bulb, Bingo!! My current Tohatsu fuel line in use is 10 years old and the primer bulb works as when out of the...
As per the OP's post 9 to 10 miles off-shore it's nothing compared to the usual 20 to 30 miles off shore boating to far away islets I usually do with a 15 footer Rib powered with just a 18 HP motor. Just check the weather conditions prior outing and carry a powerfull hand held WHF radio as a...
If you can take out your combo periodically say max 2 months time from fresh or salt water scenarios and high pressure wash the hull area, poontoon tubes, etc you'll be able to clean whatever starts to be adhered much faster and with minimal effort than leaving it unattended floating for too...
Is that a new motor to you ? Seems the 15 & 20 HP will go that route when trying to tiller shift with motor off, should work fine with motor on...

Disassembling and assembling back the lower leg it's a straightforward operation. Have you removed the clutch cam and cam rod out of the lower leg ? If so must reinstall it back as per the drawing.
If you set the lower rod in neutral (prop must spin freely) and the upper lever at neutral too...
As for any cavitation, prop aeration issues those Yams likes to be motor/transom matched at a certain height in which the hardened water flow skims right under the upper small plate when on plane, top setting in which the motor achieves its max prop thrust. Try it, nothing to lose, much to gain...
You must always pre lube with oil or grease any plastic or bakelite fitting before inserting it into any rubber hose, seen many broken fittings due to too much force applied when inserting the fitting into a dry hose...

You're welcome FB 64,
Out of curiosity report which aux motor brand and HP ended buying. Would suggest to buy a nice pressure gauge for that large inflatable carrier, pump all the air chambers and keel to their max recommended working pressure to ensure an overal rigid structure specially when...
If I use manual choke and start the motor the carbs seem to flood and spill gas out the intake side. Are all 6 carb's floats well height adjusted to factory specs, needles sharp pointy looking and needle's seats impeccable cleaned to a shinny condition while checked with a flashlight ?

A 15 Ft Sib is an excellent carrier platform for diving purposes, will handle 4 divers and diving gear which equates having 5 divers and a tender man on board, to work well in extreme variable weather conditions will be better to count with a 30 HP short shaft motor.
