Checklist Needed For Winterizing a Merc Four Stroke

3 posts in this topic

I'm winterizing my boat for the first time and was wondering if someone could give me a checklist of what I need to do?

I have a Merc 115 four stroke outboard. What do I need to do as far as fogging, changing the oil, etc.

I'm also wondering what I need to do on the boat itself? Do I need to pull the batteries, flush the livewell lines, bilge, etc.? I'm storing the boat outside so do I need to fill the lines with anti-freeze or just blow them out?

Any help would be greatly appreciated.

With motor hooked to muffs or a water supply disconnect gas while running motor and when it starts to race spray fogging oil into the carb. Keep doing it for about a minute then really spray hard till it dies. Most motors will die immediatly with the fogging oil some motors will run forever on it. Remove plugs and spray each cylinder real good then replace the plugs and give it a quick crank with plug wires disconnected.

Drain and fill lower unit oil, Pull plug on boat and tilt back so any water getting in will drain. Jack trailer up and use jack stands to reduce flat spots on tire treads. I am sure there is others but the most important is draining and re filling the lower unit. If there is water in there and it freezes it can bust open that lower unit.

I'm not 100% certain, but I believe the 115 Merc 4 Stroke is fuel injected.. which means there are no carbs to spray the fogging fluid into. What I would do is to run a fuel stabalizer (stabil, seafoam, 2+4, etc) and run the engine for a while on the hose to make sure you've got stabalized fuel run through the fuel system on the motor. Then, remove the spark plugs, squirt some fogging fluid into the cylinders and then, with the spark plug wires off or with the kill switch pulled, turn the engine over a little bit to get the fluid worked in.

Everything else is correct above.

      recommendation for first timers to northern Minnesota?  we need decent lodging, boat or sitontop kayak, smallmouth is our favorite but we will fish for anything that will bite artificial.  thanks in advance for any help.

      My Alaska trip fell through, so I'm thinking having never been to Minnesota that should be my destination. thinking a week in august. Probably start International Falls or Duluth. We need a resort with sit on top kayaks or aluminum boats, comfortable lodging without being plush and not ripping our heads off pricewise.  We will target Smallmouth, but if it will hit a lure I will fish for it. any recommendations would be greatly appreciated.

      Went out of Stoney Point sunday morning.  FYI Watch for deer almost smoked a few on the 20 mph section coming back into the access!  There is an ice heave forming off of the rocks going straight north.  If you want to fish Paris Trench people were crossing instantly using boards.  We weren't gutsy/brave/stupid enough to cross there since we were pulling a trailer behind a four wheeler and had 3 of us with all our gear.  The ice was sketchy from access to point at the point the ice heave goes a little further away from shore and it allows you some room to avoid the point's tip.  There is open water immediately around the point tip but ice looks great if you follow the tracks and avoid huging the tip.  We couldn't find a place to cross the ice heave to get to Paris Trench so we were going to try a few spots further north since we could see a few groups set up north a ways.  About 5.5 miles north of the access the ice heave quits and you can cross it without any worries.  Since we could cross the GPS spot we wanted to fish was only 2.5 miles away and we fished there.  Out in the middle we had 26-28" of ice and barely made it through.  While fishing a plane landed on the lake and a 1/2 ton extended cab pickup came from the NE some where, it was too foggy misty to see where and we didn't see him leave.  Coming back from Stoney Point's Tip to the access was very sketchy.  Made me nervous since there was a lot of slush and water but ice held us up.  If you plan on going out next weekend you may need to find a different access, or atleast I would!  Talked to a guy who came in behind us, they crossed the ice heave at the access using boards how they did and they said it was very slow and only got two.
