I have a 2013 x30 with the saltwater package on a 6.0. I've followed the flow of water to the best of my novice ability and it appears that the boat heaters have anti-freeze circulation. It this correct? On a side note, does anybody notice that these heaters are virtually useless? Only a couple of the vents get mildly warm.

Do you have the Y on the return for the heater? and sometimes you need to change where the hot water is pulled from. My first is the Y, return.

Keep in mind, I don't know the routing on a SS, so, Im sure someone will be sure if this will fix the issue your having.

I don't think that I have that Y fitting. The hot water appears to be pulled from the closed system on the engine and not the heat exchanger.

Your heater should have the same antifreeze in it that your engine has. You shouldn't have to winterize the heater on a boat with closed cooling.

The heater in my 2012 is essentially worthless.

I would have guessed that being closed cooling but was not sure on those. Sure someone could help you here.

I'm not sure you can use the Y fitting with closed cooling.

The heaters on our old 2003 Malibu 23XTI were amazing. They blew hot as sh#t. Almost to the point of needing to turn them off because you would get burned.

Agreed - Ilmor switched to a 140 thermostat (I Think) Vs Indmar was a 160.

Heater never really gets very warm, glad I added heated seats too, this is very nice.

Heated seats are the real goods on those chilly mornings. My wife uses them all the time. They certainly make it an easier decision for get to come out on those cooler days.

Off my initial topic...what block is this 6.0l Ilmor? I'm assuming a GM block.

Pretty sure it's GM. Might be their LS series block.

I have a 2012 X45 Closed Cooling in South Louisiana. We havent really ad any hard freezes yet but im trying to decide if i need to winterize or not? I dont live right by where the boat is stored.

Do I even need to winterize a closed Cooling Syetem? If antifreeze is in the block and stuff that would have a lower frrezing point than a non closed cooling. Anyone have advice for this

Have any of you switched the thermostat in the Ilmor to a 160? I thought I read on here somewhere that perhaps MC/Ilmor were even doing this now?? Did I dream this?

drain your exhaust manifolds as they take in raw water i believe, and i pump rv antifreeze into my ballast, usually about 3 gallons.
