Engine room heat

I put the two glue on to engine oil pan type heaters and have been very happy. Takes awhile to heat up but slowly turns your engine blocks in to two large heat sinks. With heat reading unit I will find my oil pans 75 degrees and the top of my Cummins B series will be 55 degrees with outside air temps below 30.

I set my whole system up to drain into the bilge.

Open a valve on the waterheater and the water lines.

Into the bilge and pumped overboard.

I never use the pink stuff in my water system.

I did try cheap vodka once.

That was fun.

I keep a remote reading wireless thermometer in the bilge and another that reads inside / outside the saloon itself.

Even when it got down 18 degrees outside for several days, the lowest I got in the cabin was 30 and the engine compartment to 34 degrees.

I keep a small heater set on 'freeze protection' and it keeps the cabin above freezing. To me it's just another excuse to stop by and visit my mistress during her winter sleep.

Here's the cover I was talking about...I think it's the reason why the boat holds onto its heat so well;

I don't run pink through my FW system. I just blow air through it after empting the HW heater.

Remember it is usually the coldest weather , and an ice storm that will cause the local power to go out , perhaps for days or longer.

This is fine if the boat is winterized or has non electric heat.

Seawater can and does freeze hard enough to crack seacocks or split plumbing.

ALL of the winter operation folks I have seen use Keel Cooling and Dry Stack , so after a greuling day of making money , they can just walk away even at -10F.

Heading down to the marina after a hard freeze to see if the power happened to stay on or if the boat sank , is muchunfun.

The previous owners son got back to town and confirmed the boat has never had any kind of heat in the engine compartment since they bought the boat in the early 1990's.

Long term power outages here aren't a problem like they might be in a heavily populated area. At most the power goes out for a couple hours at a time. This may be due to low population numbers, a large aluminum smelter in town, and what electricity the smelter and town doesn't use gets sold onto the grid, so there are some serious reasons to keep things up and running.

The PO's son is a mechanic and his Dad was a structural engineer, so I think they knew/know what they're doing...I'll be chucking something down in the engine compartment before it gets to -20C, just for my own peace of mind.

The brackish surface water does freeze here in quiet areas, but the underlying salt water never has. The channel does steam spectacularly from the temperature difference with the air at -20C though! Big time beautiful at sunrise and sunset
