Re: Heat lamps for temporary freeze protection
Heat tape designed for home water pipes is mostly about copper which is an excellent conductor of heat. Synthetic rubber engine supply lines not so much.
Doing this right after dark on Friday night is going to be a PITA and it's only supposed to drop below freezing for a few hours early Saturday morning. If the boat can be plugged in, I'd go with incandescent light bulbs in construction cages inside the engine compartment and assuming a pressurized water system, I'd open the taps to a slow trickle and not worry about it. I'd do the whole thing right on Saturday in daylight with temps in the 40s. It's going to be much colder next week, but there's time to get it done right before then.
