Amp hours per what time period? His assertions are wild and without
merit. I rarely leave my RADAR in transmit mode full time unless
warranted by the conditions and situation.

20 to 30 amps is the average usage of the electrical and electronic
equipment on my boat use which is probably representative of well
equipped long range cruisers whether they be sail or power. I agree
that on a boat of your size, doing local cruising, power demand is no
doubt much lower. Obviously your power is adequate for your boat - no
problem with that. My original assertion was that most outboards
offer limited battery charging capability. As a rule that is a true
statement but yours may be different.

You probably know this already but per the COLREGS boats equipped with
radar are supposed to use it:

Rule 7

Risk of Collision

(b) Proper use shall be made of radar equipment if fitted and
operational, including long-range scanning to obtain early warning of
risk of collision and radar plotting or equivalent systematic
observation of detected objects.
