Just droped a drop light in the Nautique 40 watt.

Could also just pull the top of the T-stat housing and fill motor with a mixture of antifreeze, but light on the water. (Just in case there is some water still in the block, it will not dilute even further.) This will also fill the coolers too. Only problem I see is the line from the outdrive to the seawater pump. Like liquid asset mentioned, pull that hose at the pump and drain and reinstall.

I used to do the 100w light bulb trick and it would keep the engine compartment above 32 degrees when is was 22 outside.
I also left the drain plug out so I could look in and see if the light was on.

Dang.....it's 7:30pm and is has already dipped down to 70 degrees out. At this rate it might get down to 60 later tonight and I'll have to wear a jacket.

I'm boating Sat.
