Preventing Freeze-up


MNCPRGUY

Recommended Posts

Used my 2011 Polaris Sportsman 550 EFI on Upper Red yesterday. Fishing was HOT but when it came time to leave, the wheeler was not! It turned over fine but would not spark, sputter, or fire. My mechanical knowledge would fit in a thimble but my guess is the injectors are froze up (it's -21 this morning). Any other thoughts, and more importantly, how do you prep your machine for cold weather to guarantee a ride home?

I have a polaris 500 sportsman and I have had the same problem when very cold, would not start with the electic start but I pulled the rope sart a couple of times and it took right off. I think with the severe cold the battery will not put out enough juice to start it with the starter.

When it gets very cold out, I usually pull the rope instead of the starter.

I run 5-30 Amsoil syntheic in the crankcase so it will turn over easier.

I also put Sta-Bil in my gas so I do not have to aorry about freezing up a gas line.

I use mine of and on all winter with zero issues but like I said, I do have to use the pull rope if it gets real cold or it has sat in the cold for a 4-7 hour stretch.

I might guess that with it that cold out, maybe the starter did not turn the motor over fast enough as the oil is too thick from the colder temps or you could have a bit of a gas line freeze up. The thick oil can drain your battery very fast as it is so hard for the crank to turn over in the thicker oil. The lighter synthic oil will help with that also.

For future trips, its always a good idea to start your machine ever hour. This will help but most importantly you'll know of problems before its too late. I will always start my equipment before dark or before all people around me have left so I worse case I can get help...especially when way out there.

I bring along an old sleeping bad that I use to cover my Snowmobile front. We had an ATV with the same issue a few weeks ago. Put it under an Eskimo 949 and let the heater warm it up for an hour. Starting it up every hour like others said is your best method.

-31 2 weeks ago after running through snow and slush. Ended up using the fish house covers and heaters to warm up the wheelers. Also brought along my trolling motor battery for back up as I have no pull start.

I also brought along an extra battery and cables.

I mounted a 300 AH garden tractor battery in the rear storage box and got rid of that thick as mollasess at -15 Amsoil 5w30. Put in Mobil 1 5w30 and it starts all the time. At -18 the Amsoil would not even pour out of the bottle. Mobil 1 poured out of the bottle like it was warm out.

My machine is fuel injected and it sure seemed like it had plenty of battery life. It cranked and cranked at what sounded normal speed intermittently for a good 5 minutes or so. I don't have a pull start or choke option. It did start fine after I got it home and back in a warm garage.

Based on the responses, it looks like my best option for extreme cold is to run a lighter weight oil, add so de-icer to the fuel, and carry a spare 12v battery and a set of cables. Am I on the right track with this line of thinking?

I also bought quick connect battery connectors and permanently mounted cables to both batteries. When I need the jump, I just plug it in. No need to carry jumper cables and try to get them hooked up. The cables could be left hooked up as long as the battery is secured to the ATV.

My Foreman did a funky thing to me last weekend. Once it turned supa-cold into Sunday morning, while out on the ice, it would turn over but ran into the "it would not quite fire" stage. I notice the 4x4 green light would not light up when trying to start, so thought it might be cold battery.

I do have a rope pull and used that and it worked perfect. Glad I have it smile Battery must have been just weak enough not to spin in fast enough. I do always have it plugged in so it must be on the last legs of its life. It is at least three years old. I was even starting it about every hour, and when i pulled it it started fine and right away. But holy cow does that single cylinder like to pull that rope in quick wink

Might try to get through the winter, but it is battery time for sure for me I think.

    • Sounds pretty sweet, alright. I will check them out, thanks.
    • If you really want to treat your wife (and yourself) with a remote operated trolling motor, the Minn Kota Ulterra is about easy as it gets.  Auto stow and deploy is pretty awesome.  You just have to turn the motor on when you go out and that the last time you have to touch it.   24V 80lb.  60 inch shaft is probably the right length for your boat.  They ain’t cheap - about $3k - but neither one of you would have to leave your seat to use it all day.
    • Wanderer, thanks for your reply. I do intend for it to be 24 volt, with a thrust of 70-80. Spot lock is a must (my wife is looking forward to not being the anchor person any more).  With my old boat we did quite a lot of pulling shad raps and hot n tots, using the trolling motor. Unlikely that we will fish in whitecaps, did plenty of that when I was younger. I also need a wireless remote, not going back to a foot pedal. We do a fair amount of bobber fishing. I don't think I will bother with a depth finder on the trolling motor. I am leaning toward moving my Garmin depth finder from my old boat to the new one, just because I am so used to it and it works well for me. I am 70 years old and kinda set in my ways...
    • Dang, new content and now answers.   First, congrats on the new boat!   My recommendation is to get the most thrust you can in 24V, assuming a boat that size isn’t running 36V.  80 might be tops?  I’m partial to MinnKota.     How do you plan to use the trolling motor is an important question too.     All weather or just nice weather?   Casting a lot or bait dragging?   Bobber or panfish fishing?   Spot lock?  Networked with depth finders?  What brand of depth finders?
    • We have bought a new boat, which we will be picking up this spring. It is an Alumacraft Competitor 165 sport with a 90 horse Yamaha motor. I will be buying and installing a trolling motor,  wondering if I can get some recommendations on what pound thrust I will want for this boat?  Also, I will be selling my old boat, is there a good way to determine the value on an older boat ( mid-80's with a 75 horse 2-stroke  Mariner motor)  I will appreciate any help with these questions.
    • Sketti...  not out of a jar either!
    • Lol yeah I watched that
