Winterization anit-freeze for two winters
« on: November 15, 2019, 12:36:33 PM »

Hi everyone,
This past season we didn't put Sea Life in the water.  With other plans over the summer, we decided to take a hiatus.  Everything was winterized for last winter and over the summer, we did not do or change anything to the systems.  I'm thinking since everything has been untouched, we can go through another winter.  Any thoughts if I'm missing something?
Thanks!!

Roc,
What about the transmission.  I believe it's recommended to overfill for extended storage.  FWIW my previous boat was in storage for 15 years before I purchased, except for mud wasps nest that I kept finding for years, the boat never gave me a bit of problems.
Here's to a great sailing season, year after next.

I would think the engine and potable water systems should be fine.  I assume you are managing bilge water accumulation and have properly stored the batteries.  I would also make sure the boat is well ventilated and the opportunity for mold is minimized.  And make sure no critters have found a home.

is the raw water impeller still installed?  I read some time ago its ideal to remove over the winter because they can become more difficult to remove the longer they're installed.  Since having read that, I remove mine after winterizing and leave the cover off the pump to remind me to reinstall when I commission her.  This isn't a big deal but might be worth considering.

Thanks for the tips...  the transmission is overfilled.  I do it every fall, so that's set.  I plan on changing the impeller in the spring, but good tip about difficulty getting out.  My guess is the rubber could get stuck in the housing.  I guess I'll see.  The batteries are topped off.  I was there two weeks ago to give the boat an overall check and had the charger plugged in.  I have a custom canvas winter cover which does not trap in moisture like a plastic shrink wrap could.  Also, I've kept up with keeping the damp rid moisture absorbers changed throughout the summer and I also used tea tree oil.  I freshened both those a couple weeks ago.  Never get water in the bilge, deck stepped mast.  Just in case, I pour a few cups of pink antifreeze in the bilge.

It’s that the impeller fins can become “set” at the bend they’re in, in the body if left installed. Not good.
Also, put some SuperLube on the shaft so the impeller hub doesn’t get stuck on it. You can remove the whole shaft to remove the impeller, no problem (presuming it’s an Oberdorfer pump.)

Guys : I posted (many years ago) to remove the impeller, inspect it and I squirt it with silicone to keep it nimble. Then in the spring turn it around so the blades get to bend in the opposite direction than they did the previous year!!

A few thoughts  :thumb:

I thought the concern was that the impeller itself can become stuck on the shaft.  Especially with the Sherwood since you can pop the shaft out with the Oberdorfer to replace the impeller.  BTW, I've found the Oberdorfer to be a nice upgrade from the Sherwood on M25XPB.

It's both, but even lubing the shaft can't help the issue of the fins breaking.
So -- it will pump whether or not the impeller is seized on the shart -- but the unseen and unknown problem of broken fins is an issue because, well, no fins no pumping.
