My 2014 BF90 is alarming overheat on quick deceleration, from about 28 mph for 1/2 hour. I believe I have a separate issue as then the ignition switch won't crank the engine after it shuts down on the automatic shut down ( I can use a screwdriver to go from ignition to battery at the solenoid) it starts back up and is fine. Got to where I needed to be about 10 miles, shut it down, had lunch. Tried ignition switch and it started. Same thing on my 20 mile trip back. Actually replaced ignition switch as it was not returning all the way from crank position. Tested wiring from ignition switch to the solenoid shows good. Did wiggle test, no intermittent loss of connection. I have a manual on order, is it possible that when I slow down fast I noted the tell tale is under water for a short time. Could it be that tell tale under water with possible cavitation is not allowing cooling for a few seconds? Is there a cutout of crank power for a while when this happens, like a delay relay (I doubt it). I have many years experience in the automotive, motorcycle, semi, heavy equipment etc. field. Boats aren't really any different mechanically, but I thought there might be something at least with the tell tale being under water that I'm not familiar with. Thank you in advance. In the meantime I'll search online in parts diagrams for a delay relay.
