Heads-Up for Genesis owners who still use the original rudder;
I noticed slightly higher motor temps in my last couple of runs.
My rudder pick-up is used for motor + mount cooling only, and I have a dual pickup for the ESC.
As I suspected rudder blockage with mud or something (very shallow near shore edge) I blew out the hose, and noticed water squirting straight down out the rudder bottom.
The factory installed nylon plug in the rudder TE was missing !
This is the hole that is plugged after drilling the waterchannel in the rudder. (see photo)
Obviously this will decrease the cooling significantly .
Not a big problem for me as I'm running with enough headroom temperature-wise, but for those already 'on the edge' this could cost you a motor or even worse if you use the single pick-up for the whole system.
You might be, or might not be affected, but worth checking it.
I solved this -and prevented a repeat- by tapping the hole with M3 thread, and screwed a nylon 3mm screw in a few threads with some medium CA, cutting the rest off.
For those non-metric; 4-40 should work as well without drilling.
