How much to fill antifreeze container in a 525?
 

Specifically, got the boat back from service and now the white closed cooling bottles are completely full. Isn't there supposed to be an air gap? I could not find a "full" indicator mark. Anybody have a manual showing what the proper cold fill level is? Thanks.

stock OEM hp 525 closed cooling system 3.5 gallons and and just a fyi the seawater cooling system side is 5 gallons capacity..

Thanks, but the engines are in the boat and I need to know how high the level should be on the white bottle. Cold fill level. There is a seam in the middle and I thought it was about at that seam. I remember an air gap but not exactly where the level should be. I can't seem to find a "full" indicator level mark on the bottle.

these will possibly help

You will be fine right above the seem. run motor up to operating temp and then let sit to see were your level is after that and after complete cool down.

Do NOT fill the reservoir 100 % full

Yep looks like right above the seam. Thanks guys. Ran it yesterday about 1 hour run time hope no damage. Ran perfect.

To the boat with a turkey baster tonight.
