winterization question

[BigRock44]

had my raw water wash down pump winterized last year (antifreeze pumped through) and have not used it since. anyone know if i need to repeat the process again this year? wondering if there is any way water water could have worked it's way in if it had not been used. it's on a 2014 21' sea hunt. any info would be greatly appreciated. :)

thanks very much in advance.

If you opened the sea cock that supplies salt water to the pump I would winterise it again.

Thank you Gerry.

On my Grady the raw water pump ran the wash down hose and the live well. A valve at helm did the switch over so a single pump did both.

Both lines should have antifreeze run through in the lines. And the switch over valve should have it run through as well as the pump.

TO DO:
Remove hose from seacock. Stuff hose in antifreeze bottle and run pump. Run wash down to shoot through the hose into a 5 gallon catch bucket. And switch valve over to dump into live well. Use catch bucket again for live well drainage.


DONE
That guarantees there is nothing but coolant in there. Then reconnect hose to through hull. Double clamp. Replace hose if getting ragged oR deformed.



Get both lines and hose filled with the pink stuff. Also let it run into drains ( if live well). Want antifreeze in all line, all valves, and all pumps.
