I turn it on every time before I start the boat, and I don't turn it off until it's back at the dock and the motor is shut off. Every now and then if I'm driving and we're under way I'll shut it off (back on when we stop), but that blower is pretty cheap and easy to replace so I won't be upset if it burns up and I have to replace it. Never had to replace it in my Launch after 7 years of doing the same thing. I don't really do it because I'm afraid my boat will blow up from fumes in the engine bay, but I figure it helps with overall air flow and doesn't hurt anything so why not...also now it's just habit.

I think the new Supras with the Vision have a similar feature if I am not mistaken.
I run mine a the launch ramp when we are loading gear in the boat but once she is in the water under her own power it gets turned off and doesn't come back on unless she sits with the engine off for a prolonged period of time.David

I turn it on for a few minutes at the ramp when we launch the boat then turn it off after that. If we are trying to teach someone to board or surf and I spend a lot of time at idle speed circling back to bring them the rope, then I will run it to draw some of the hot air out. Also, on hot days (over 85 or so), I will run it all the time that the engine is running and for about 5 minutes after I shut it off if we are going to float for a while. I have never had vapor lock following this process.
I think that if you are underway and it's not too hot outside, enough air is going through the engine compartment that the blower does not need to be on. But on a hot day or during times when you spend a lot of time at slow speeds, I think it's a good idea to run it to help evacuate the hot air.Al

Honestly i never run it.
It originally was for Carb engines because you get a lot of fumes and this was to clear the fumes out before you started so you wouldn't get an explosion.
They still put them on boats as a safety item but if they really wanted them to be used every time i would think they would connect the blower to the start switch and make them interlock together.
On my fuel injected boats i have never had a fuel smell.
I turn it on each year for inspection and pretty much after that it never gets turned on unless one of my buddies drives that has an older boat that needs it and its his habit.
