you know that some boat trhansmissions get very hot if you let the
propeller to free wheel? Some energy is needed to heat it up.


Yes. The newer transmission that came with the replacement Perkins 4-108
was said to be one that would heat up. So, we kept the much larger
"hydraulic" transmission that was on the old engine. It doesn't even get
warm and I can spin the unloaded shaft by hand.
