So the temps down here in Louisiana have been going up and down but havent stayed that cold yet. The lowest its been is 38. With that being said im going to be traveling for work for a bit and I was thinking about winterizing this weekend. I really dont want to pull it to the dealer and pay to have them do it. I used to winterize my malibu by simply pulling two plugs on the bottom of the engine and disconneting the exhaust hoses. Plain and simple and worked great for 8 years.

Last year my boat was at the dealer already so I just had them do winterize it for me. This year is not the case.

I have the 6.2L Closed Cooling on my X45. I have read the owners manual but some of it is unclear (http://www.ilmor.com/user_area/content_media/2013_MV8_Recreational_OM_6JUN2013-v-5.pdf)


Is it possible to plug a hose into the rear flush kit valve and pump antifreeze through the engine or can I just drain the block? Does anyone have any experience winterized a Ilmor 6.2L that they could send my way.

Thanks for the help in advance

The block already has antifreeze in it if its closed cooled. When I winterize mine (5.7L Crusader Closed Cooled) I drain the water out of the heat exchanger, exhaust manifolds, tranny & oil coolers and raw water strainer. The Crusader manual had a great picture of the system and indicated where it needed to be drained. I didn't see any pictures in the Ilmor document, but it does give some instructions on pages 8-2 & 8-3.

I have read these instructions just wondering if someone maybe had pictures like you mentioned for and illmor winterization. I want to make sure I'm getting the right thing.

Can I just run antifreeze through the boat and consider it winterized? Never have done that and curious to try it if someone has.

You need to drain it first or, otherwise, run a considerable amount of rv antifreeze through the system so that what you end up with is not diluted (rv antifreeze is not supposed to be cut with water).

Anyone have pictures of the Location of the Plugs on the Ilmor Engines?

Agreed. I just installed a Quick Flush Valve, which means that this year I can drain the manifolds, block, and exchanger on my Ilmor MV8, and then fill with antifreeze via a bucket and hose hooked to the intake. Simple. Now if that darn impeller were just easier to remove!

Because I just installed my flush valve, and was searching on winterizing. Don't worry...no one is doing a snow dance just yet!

Snow necro in the middle of June!!!

Oh, btw, you could do the same thing by just pulling your raw water line off the bottom and putting it in the bucket!

Yeah, I just go nuts on eBay sometimes and these parts show up!
