  • Engine block heater

    Does anyone keep their boat on a lift on their dock all year long without winterizing. I live in Alabama and would love to keep my boat ready to go through the winter for those warm weekends we get. I am curious if anyone has a heater with a power back up. I would like to pull the freeze plugs and keep the block warm enough to not freeze but be able to drop it in the water when it is warm enough. Any thoughts...

    Interesting concept. I would assume that a block heater would warm the water in the engine sufficiently to keep it from freezing. I would recommend using a block heater on each side for plenty of heat, and redundancy....that's what I used to do years ago when I wanted to be sure my truck that never saw the inside of a garage would start when it got cold.

      I would think too many air pockets and not enough circulation on an open cooling system, unlike a vehicle with a closed cooling system. sounds like a gamble to me

        When I haven't winterized yet and the temps get cold, I place a quartz heater in the engine compartment and close the engine cover. Keeps it nice and warm inside, and doesn't get hot like a trouble light. a quick drain of the block and a heater may be an option.

          here's an idea???



          I use a milkhouse heater to heat my 1 car garage, and it worked great yesterday when it was 18 degrees outside

                  Twist the drains and walk away. Once installed it takes 1 min or less to twist the valves and you are done. Then when it's warm twist the valves closed and enjoy the day.

                    what about pockets of un-winterized water?
                    The water passages create too many pockets, and they're not all gravity drained

                      No offence to the heater guys but the time it takes to set up a heater with the extension cord and rolling the cord back up time wise, the drain kit would be faster and just as safe.

                        I use the kit above and never had an issue.

                        I do many of our club members boats the same way.

                        Never had a problem.


                        What pockets are you referring to?

                        I follow every step in my owners manual accept the real OCD step of greasing the shaft flange between the tranny and shaft coupler. I also do not tape my exhaust flaps down as instructed. My boat is inside a storage facility.

                        It says to pull lanyard and crank it over to remove any kind of pockets but I don't have a lanyard safety switch. They are ghey so I pull my coil wire.

                          I'm just trying to picture the water passages..... if water is going uphill then goes downhill and there's a pocket of water that cannot be purged out, I'd think that it would freeze in there.... and if it was in a location that was tight, the only way for the ice to expand it for something to break.

                          take for instance the 1/2 inch block plug..... is it at the very bottom of the water passage, or is it an inch above the passage? If it's above, then you've got an inch that'll freeze. then you've got the nose up tilt of the engine block..... what about the water from the plug to the back of the block?

                          Maybe I'm overthinking it.... but if this were the case, seems like PCM, Indmar, and others would lust have the valves in place to begin with.

                          edit:
                          and what about the water at the thermostat housing?

                          best pic I could find..... but I'd say water will sit in the places indicated....

                            The ice could expand upwards in your example.

                              I think you are over thinking things slightly.

                              When the water freezes it has to go somewhere. Say we use the 1" gap from the drain to were the water catches or in some kind of valley where water sits. When the water freezes it will expand and it will find its way out through the valley or the passage that now is not blocked due to have drained.

                              If we take a metal dog bowl or say a cattle watering tank and let it freeze. Why does the metal not break or bust. Why do the plastic ice cube trays that you freeze for ice for cold drinks not break?

                              The water is not under pressure with the block drained. Therefore the passages are not under pressure and the water has somewhere to expand to.


                              As far as the Tstat, you are supposed to drain the hose running from the tstat housing to the water pump.
