Unwinterize ?
 
What is common for getting boat watter ready after winter ?

ajholt7 03-04-2010 1:36 PM

Make sure all your plugs are in. Check all fluids. Change raw water impeller. Don't forget the often neglected trailer maintenance.

If winterized correctly: Hook up trailer, drive to boat ramp, install plug, back boat into water, fire up and let idle till warm, unhook bow strap, back off trailer and go play.

Depends on how it was winterized & what equipment you have? What boat? Engine? Do you have a heater or shower?

I also always replace the oil/oil filter as it has sat in the engine for 6 months. Change the tranny fluid if it hasn't been done in a couple years. Replace impeller as stated above and reinstall any required plugs. Check your belts and maybe change spark plugs if it hasn't been done in a few years either. Just give it a once over to make sure all your Navi lights work, you got all the life jackets back in....whatever else you may have taken out. Connect the trailer and make sure all lights work. Air in the tires if needed. I usually clean the boat again even though I did it before I put it away.

Give it a big hug and a kiss if you haven't seen it in a few months!

Go shred the liquid gnar!

Just and FYI, its never a good idea to leave the used oil in the crankcase during storage. Used oil is acidic and corrosive and will etch the soft metals such as bearing and pistons. It also contains moisture, which is a normal byproduct of combustion as well as the environment the boat is used in. The oil and filter should always be changed in Fall and the engine run afterwards to circulate the fresh clean oil.

^^^ I do an oil change before I put the boat away and when I pull it out again for the spring. Are you saying I should completely drain all the oil out of the engine before putting away for the season?

No. It sounded like you left the previous season's oil in for the winter and then changed for Spring, my bad. And no, don't drain and leave empty as this allows condensation to build up in the crankcase as well. To be honest, it's not necessary to do an oil change in the Spring, if one was done in Fall. But it doesn't hurt.

Just change it at the end of the season so you don't leave used acidic oil in it all winter. There is no need to do it again in the spring.

How if the oil is just sitting and engine is never started?

bill_airjunky 03-05-2010 11:34 AM

There are so many trains of thought on when to change your oil. I've tried to validate one or the other but haven't seen any real authority's proof either way.

cjh1669 03-05-2010 11:37 AM

I've heard both too, but tend to think you should change it before the season due to the condesation that builds up ontop of it through out the winter. That's what I do with my lawnmower:D

Agreed. Why would you put new oil in, have it sit for 6-7 months in freezing weather and then just fire it up and be good to go. Doesn't make sense to me, heck even cars say 3-5k miles or 3 months

brucemac 03-05-2010 12:16 PM

i've heard both sides too. i just do my lubes in the spring along with a fresh impeller. i'd reconsider if i was putting a ton of hours on each season.

rallyart 03-05-2010 3:38 PM

I always, and lots of shops also, loosen the belts over the winter so you need to check that they are still tight.

I've never heard to change your oil every 3 months.

I live like 5 or 6 miles from my office. So it takes me a lot more than 3 months to get up to 3000 miles in the truck.

The reason is because of oxidation. Oxidation happens faster at higher temperatures hence the mileage interval but oxidation still occurs even if you dont put many miles on your vehicle.

Effects of oxidation within the engine can be seen in the form of accelerated acid formation, corrosion, oil thickening, deposit formation, and accelerated wear.

Donski 03-05-2010 5:33 PM

I just change my oil before I put it up for the season. I see no need to waste fresh oil unless someone has a valid reason? If unused oil were to lose it's viscosity after 3 months then you'd see a lot oil on clearance racks. Something I've never seen in my life.

jimmy_z 03-07-2010 5:33 PM

Has nothing to do with viscosity Brandon. Once the oil is introduced to oxygen then oxidation starts to take place. Oil is sealed in a container on the shelf. Once the seal is broken the "clock" starts. The "clock" speeds up when the oil is heated.

The debate on changing oil after the season ends or before the season starts will always be argued. But the results of excessive wear to engines either way has yet to be proven. Either way isnt going to cause any excessive damage to your engine.
