Raptor Winterization

[JHutch]

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?

Amazon has several for PG.

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 do. For $15 and 10 minutes of time it's good cheap insurance.

I run it up to temp. Remove all the plugs and reinstall . Hookup a pump and pump antifreeze through the engine till it comes out pink. I let it sit for 30 minutes then I remove all the drains again. About 10 minutes of active easy work.

Hey guys.

I have ready many post about winterizing the raptor and read my manual extensively. Is it really that easy to drain the raw water side? 2 blue plugs, vdrive plug and heat exchanger plug? And the heater is on the closed side?

As I was searching around my boat last weekend I was looking for a water strainer for the ballast and couldn’t find it. May it be hiding behind a panel?

Lastly I found all my ballast pumps and they are mounted horizontally. Can I still push air the rough them to expel any water that may be left in the lines?

Advice is always appreciated.

My 2016 Mojo doesn't have a strainer for the ballast intakes, so you are probably good.

Each year raptor is a little different, there should be a crossover hose with a brass fitting, be sure to disconnect and let drain.

You might also have a transmission drain hose with a blue plug. My 2018 had one, but my 2021 does not.

There isn’t a strainer for the ballast.

Heater is on the closed loop cooling system.
