"Neat idea, GD. I'll try that. My trick is to refire the motor just before leaving the boat, to refill the now cooler (or cold if left overnight) carb bowls.
Marine carbs run dry after sitting a week in the heat of the bilge--common problem. One solution is to go to electric pumps but, as stated above, mechanical pumps are far more reliable!
The ULTIMATE solution is to go with BOTH. Put the electric pumps in series with the mechanical pumps and use a momentary push button to run them. This acts like a 'booster pump' to fill the carb bowls, but AFTER you've wheeled the motors over to make damn sure water didn't sneak in on during the week. (Those instant starting EFI motors are hand grenades if water leaked in overnight.)
I haven't done this yet, but someday brother!
