First Time Winterizing a Moomba
Hello all. This is the first time I have winterized a Moomba and the Jabsco Ballasts. I think I am done, but of course I always double think things and occasionally doubt myself. First off.....my boat will be in my shop all winter, and it gets maybe at the lowest point 32 when not heated. I have never in the past had anything in the shop....including water bottle freeze or slush. This is what I have done according to the manuals, and contacting Indmar support.
1. Fuel Stabilizer (marine) in tank and run at operating temp for 15 min
2. All blue engine plugs and drive plug taken off and left off in plastic bag
3. Blown out all points with compressor (per Indmar tech suggestion)
4. Sea Strainer blue cap opened and blown out as well.....no water in clear tube
5. All plugs left open and loose ones stored.
6. Pulled all 8 plugs....fogged for 2-3 seconds and cranked engine 2 times.
7. Put old plugs back in, but not all the way.....I will replace in the spring $$$ for right now, but wanted holes covered
8. Took out impeller and gasket and stored in plastic bag
9. Again, blew out all tubes, blue access points and impeller in hose and out hose.
10. Seems to be no more water in the lines.
11. Check anti-freeze level and tested the cold temp level and ts ok well below 32 degrees
Ballast:
1. Took all plates off pumps and rubber o-rings and stored in plastic bags
2. Took out all impellers and stored in plastic bags
3. Removed all ballast bags and emptied and left to dry (except center bag)
4. Blew out all "in pump lines" and "out pump lines "
5. Blew out all exterior port holes with the exception of the ones with relief valves
Stored everything in plastic bags after they dried.....nothing laying on each other to create flaws in rubber, seals, or gaskets
Left front center cushion off and center access hole off to let the hull vent and hopefully dry out center ballast bag
Thats all that I have done. I believe I am remembering everything:)
Only question is the batteries. I have the maintainer battery hook up and I didn't know if I should plug it in for the whole winter? Plug it in on and off? or disconnect both batteries, pull and charge on and off over the winter?
Any comments, suggestions, recommendations would be greatly appreciated. This is my first time with this boat and a raptor.
Thanks again

First Time Winterizing a Moomba
The raptors are so easy to winterize.
Most dealers up here just pump 5-6 gallons on marine antifreeze through them, takes 5 min.
Full drain ballast, fuel stabilizer, oil change in fall or spring depending on my mood....
I just pull the blue plugs and crossover hose and let it drain, then put them back in, done.
Even if I was in a warm climate, I would still probably pull the blue plugs, just wouldn’t want lake water sitting in the cooling loop for months.
