captpierre Posted October 21, 2019 Report Share Posted October 21, 2019 Winterized my girl. 115 Yammy. I’ve  always changed the lower unit oil. 12 years. This time just checked it. Looks great.  Stupid or smarter? Link to comment Share on other sites More sharing options...
DRIFTER_016 Posted October 21, 2019 Report Share Posted October 21, 2019 I just check mine as well. As long as it's not cloudy you're good. Link to comment Share on other sites More sharing options...

lew Posted October 21, 2019 Report Share Posted October 21, 2019 Guess it all depends on how much the motor is used over the season but I always changed mine every fall. Very easy and cheap to do and good insurance. 2 Link to comment Share on other sites More sharing options...

Big Cliff Posted October 21, 2019 Report Share Posted October 21, 2019 Remember to change the "O" ring seals too. Link to comment Share on other sites More sharing options...
Garnet Posted October 21, 2019 Report Share Posted October 21, 2019 Another thing is don't to efficient at getting top screw in. A little space is necessary for oil expansion. Link to comment Share on other sites More sharing options...

bigbuck Posted October 24, 2019 Report Share Posted October 24, 2019 Didn't do mine this year. The boat has about 5-6hrs on it this year. I checked the fluid a couple of times and it was nice and golden, no crap or cloudiness. Link to comment Share on other sites More sharing options...
davis Posted November 1, 2019 Report Share Posted November 1, 2019 stupid question here - do any o-rings work, or are they marine specific and/or manufacturer specific? Link to comment Share on other sites More sharing options...

Nothing stupid about it. If the seal you're thinking of using is oil resistant and of the proper size, it should work fine. Dan. Link to comment Share on other sites More sharing options...
Mister G Posted November 2, 2019 Report Share Posted November 2, 2019 Don't forget to remove the prop and clean the shaft......check for fishing line and RE-GREASE the shaft for easy removal next season........and use a new SS cotter pin. Link to comment Share on other sites More sharing options...

Anyone know if crappy can sells stainless cotter pins? Or any other easy (multiple location) places that sell em. I’m winterizing this Thursday and I’ve never taken my prop off my boat. This sounds like a smart idea.  stupid question I know but I’m a new boat owner and I’m learning! Edited November 4, 2019 by AKRISONER Link to comment Share on other sites More sharing options...

This sounds like a smart idea.  stupid question I know but I’m a new boat owner and I’m learning! If you haven't removed the prop in several years you may find it difficult to remove. A 3# hammer and a block of wood is now your best friend. Place the block of wood at the thick end of one of the prop blades and smack it with that hammer 2-3 times.......if no movement rotate the prop to the next fin blade and repeat until it loosens and comes off.......now check the spines on both the prop and shaft.....it should show corrosion between the SS prop and brass prop hub splines.......clean with penetrating oil and a brass brush..........once clean grease them both up ( I use wheel bearing grease) for a EASY removal next year. Of course check for fishing line, and replace the thrust bearing/washers the way you removed them........and then the prop nut and your NEW SS cotter pin. 1 Link to comment Share on other sites More sharing options...
