Winterized 440 raptor

I filled the strainer with antifreeze and fire the boat up and put 4 gallons through it. Is it recommended to pull the plugs also after that? On a 2020 does the antifreeze reach everywhere with 4 gallons?

thanks a bunch.

Normally you pull plugs first then run pink. Is it pushing pink out the exhaust?? Should have after 4....

If you are parked with anything behind you be ready when you start it....it shoots a lot of antifreeze as it revs up at start.

Yeah it was coming out of the exhaust. Driveway way pink lol

I believe you need to drain the water in the engine prior to running antifreeze to ensure it doesn't become diluted.

Then you are good!!

bsreid raptors are close loop so only water is in the v drive, hose up to impeller, heat exchanger and coolers(oil and trans) then out thru manifolds and dumps out the Y pipe. So as long as you put in antifreeze before the V drive it pushes all the water out quickly compared to dilution in the block on and open loop
