Putting in antifreeze - to run engine or not???

I am about ready to embark upon putting antifreeze in the 96 sportster.

I see some use a method in which the engine is on and antifreeze sprays out the back, while others put it in with the engine off (like the manual says)….Is one of these inherently better or worse? I wanted to do as the manual said with pinching hoses 3 times, but thought I would check.
 
I have always run all my boats/skis. It may be overkill, but it ensures that water is blown out the exhaust/waterbox, and antifreeze has had a chance to get in. The most important thing is to make sure the plug is in the engine water outlet "calibrated fitting" so that it all doesn't just drain out the back.

I would say it is a matter of preference. If I lived in michigan, I would, If I lived in southern florida, I would not bother.

I think snipe has an article about winterization floating around. A quick search might bring it up.

p.s. If I remember to, I'll post a photo or two of what happens to an engine when it freezes, even in a temperate place like TN.

i've done it both ways, pouring it in the intake hose of a running engine I think assures no pockets of water anywhere in the engine but who am I to question the Seadoo engineers...

Gamerse - what do you mean "The most important thing is to make sure the plug is in the engine water outlet "calibrated fitting" so that it all doesn't just drain out the back"??

Are you talking about putting in a clamp on the hose after th "T" to the flush connector where you can hookup a hose? This would then prevent the antifreeze from funning out the back then???
 
Potatoes pota'toes. It is the same thing. Some people have plugs, others clamp the hose aft the T fitting.

The short answer is yes.

Makes sense, thanks...

So am I understanding if I decided to run antifreeze through running the engine, I plug the calibrated outlet section after the flushing T....Then start engine and pour antifreeze into a funnel hooked to the flushing fitting and watch until antifreeze comes out the back and turn off engine and I am done?

I dont have to do all the plugging/clamping to the hoses, disconnect the two hoses referenced in the manual?
 
I use a small submersible pump i bought at harbor freight for like 7 bucks. I made a hose for it with clear tubing and a garden hose end. Attach the hose end to the fitting on the boat and put a gallon of antifreeze in a bucket and pump it into the top fitting on the boat.
 
I also have a submersible pump but i hook mine up to the hose connector at the stern of the boat.But you must also pinch off hoses. best to follow the owners manual because there is a specific order to it. It took me like an hour the first time but now i can do it in about 10 minutes. You do not want to make a mistake.

Love photobucket. Make sure coolant gets through here ^ its not rocket science lol.

p.s. If you want to go crazy, remove the hose from the jet-pump, put a bilge pump in a five gallon bucket of coolant, plumb it to the hose you disconnected, start the engine, and pump coolant through the way it would, when it was in the water. rofl
