2006 Response LXi Winterization Question


Recommended Posts

Ok, so I know there are tons of posts on Winterization and I could search and read all day. What I am looking for (since I don't have the engine manual) is what I should do with my "No Cats" 2006 Response LXi stock engine (not the monsoon).

Do I fog each cylinder, or can I just use fogging oil and or the method somebody posted below?

link to the other method I saw, start at about 4:30

Where are all the engine water drain plugs and other than the drain plugs what else needs to be drained? Or can I warm it up for 10-15 minutes and then use my 1 way bypass valve to suck marine antifreeze (the non-toxic kind that I use in my RV as well) into the engine until I get some pink out the exhaust ports? I assume it will suck it in and that I don't have to actually pump it correct?

I am not new to winterizing boat engines both outboards and inboards but this is the first one I have had that is this new and has fuel injection. My other inboard was carbureted so I would just spray fogging oil down the carb but it would never smoke like an outboard or be enough to kill the engine.

I also never had a 1 way bypass on the lake water intake like this boat has so with previous boats I would just pull the 4 drain plugs and call it good.

I would appreciate it if there was anyone that isn't completely tired of hearing about winterization to chime in and give me your thoughts.

Thanks in advance!

I just have my daughter crank the engine with the kill switch pulled for about 15 seconds and spray fog into the throttle body. Pulling the plugs will verify if the fogging oil made it to the cylinders. Always does.
