winterizing a 500 efi

[mrfixxall]

pink antifreeze still freezes @ 17 degrees,my refractor tells me so!

on one side theirs a plug,the other side you have to remove the knock sensor to drain the block,dont ask me why but i think its a stupid location for it..

warm up the engine then drain what you can by pulling the plugs and hoses,get a 5 gallon gas can and fill it with antifreeze,find a old section of 3/4 garden hose and cut to fit,set the gas can on your swim plarform and hoof it up to your ear muffs.have a friend start your boat and release the vent on the gas can and your engine will suck the antifreeze through the engine..make sure you take the oil filter off and dunp a little gas out of it and top it off with 2stroke oil for fogging and to lube the injectors..

Yep, the pink does freeze. It just does not expand until -50*

Allow water to drain completely (may need to clear drain holes with wire or a small screwdriver). Close drains and reconnect pressure hose. Hook up RV antifreeze tank to muffs and start engine and run until antifreeze spits out exhaust (about 4 gal.) shut off engine. Wipe everything down.

OK, I did everything just like this but couldn't get the motor to suck up the antifreeze. I put the bucket of antifreeze on the swim platform but no dice. Maybe there wasn't a good seal at the muffs but I think I'm gonna check into installing a flush kit. Then there shouldn't be any questions.
