Raptor Winterization
First time Raptor owner
Is there any need to back fill with Antifreeze if you remove all 5 drain locations? Also do you reinstall or leave out for the winter?
What does everyone do for their ballast system?
I am in KY so we get low teens for maybe 1-2 weeks a year.
Thanks!

No need to backfill antifreeze if all plugs are pulled.
Ballast system, just use pumps to pull as much as possible, pumps are self draining, ballast bags and tanks with a small amount of residual water are fine, plenty of room for expansion.
I leave plugs out until spring, the raptors have a blue plastic plug holder rack.

Thanks, I found the holder. What are you guys using to test your coolant for freeze protection? I haven't found anything for local for propylene Glycol?

So nobody is pouring RV antifreeze into the water cooling system at all? Just draining the plugs and leaving them go. I live in ND so it gets REALLY cold here.

I have drained and refilled with marine anti freeze. I just don’t need to use antifreeze anymore. Draining is all I do. 2 boats 4 seasons with a raptor.
1) not necessary
2) not all marine antifreeze is good enough
3) it’s pouring $$$ down the drain
Trust Indmar when they designed a self draining raw water cooling system. Nowhere in the manual does it suggest marine antifreeze.

I have a slightly older boat then yours... I get the motor up to temp, let it suck in the antifreeze and then open and drain all the plugs. It may be over kill but its great piece of mind and cheap insurance on freeze protection. It gets cold here, and I dont want to deal with an issue come summer.

Last year in Texas we had 6 or 7 days below freezing. Single digits. Only drained the raptor. Fired up and ran great all this year! If you have a raptor drain the plugs, forget about it, and go hunting

I just drained the plugs and impeller. Feels weird not using AF but also made winterizing a 10 minute job!
