On one side of the lower unit there are 2 screws. The drain screw is on the bottom of the front of the gearcase. The vent screw is near the top of the lower unit.
Trim the motor all the way down. Place something under the lower unit to catch the oil. Remove the drain screw then remove the vent screw and let all the oil run out.
Check the oil coming out for any type of metal chunks or large shavings. If the drain screw has a magnet on it it is normal to see some small metal shavings.
After all the oil has drained out screw the tube of oil or oil pump hose, whichever you have, into the drain hole. Fill the lower unit with oil until it comes out of the vent hole.
Next put the vent screw back in making sure the on the screw is in good shape. If not, replace the seal. Then unscrew the oil tube or pump hose and quickly put the drain screw back in. Again, before putting the drain screw back in check the seal.

Whatever Floats Your Boat

At the Shelter Island Harbor in San Diego, many large yachts and sailboats are anchored in the bay, not in a slip on the pier, so the owner has to use a dinghy or pontoon or rowboat to get there. The owner of this one apparently has no money left after maintaining the yacht to spend on maintaining the dinghy ! Actually there were a bunch of nicely maintained ones on the other side of the pier (see below) but I find the rusty/crusty one far more interesting. Not sure I would venture out into the harbor without a life jacket though...

This manual is for 2.5 to 140 horsepower. Not as specific as I would like with so many models but hard to get Nissan info anyway. Good for figuring out part numbers because of drawing descriptions.

There are two screws on the lower unit. The top being the vent and the bottom being the filler screw. Have a pan large enough to catch all the oil that drains out. You will want to inspect this oil for water and sign of metal flakes as that could be a sign of some damage. You can buy a kit that will pump the oil from the lube container into the bottom screw hole. Also be sure you buy the lower end lube that is specified for your outboard motor. After the lower end drains for about an hour, connect the kit tio the bottom hole and pump the oil in until it comes out of the top hole. Then screw in the top screw firmly. Quickly remove the filler kit and quickly insert the bottom screw and tighten it securely. Once you have cleaned the grease up you should be set to go.

BJ and JRAY answered this correct …. Just have plenty of paper towels on hand it can be messy! Also have extra lower unit oil on hand in case you have problems extracting the lower fill kit and replacing the orig screw.

Great title for sure! I wouldn’t go out on that either. What a great find.
July 9th, 2010 at 7:49 am
Haha…great advertising for Nissan "we can even keep this wreck moving" But what super textures & onboard junk details…..makes for a fab shot, Jill. Great comp on both.
July 9th, 2010 at 8:00 am
although they are both great captures, I love the "rusty/crusty" one – so much character to it!
Hope you have a great 4th of July!
July 9th, 2010 at 8:59 am
Great details!!! You mean still in working condition!!! Well seen Jill. Years ago when I went to San Diego I was amazed how beautiful were the reflections of hills and surrounding on the water!!! Great reflections here!! Have a great Sunday and happy 4th!!

Nice find, Jill. Love the reflection in the still water but it looks as if a sharp has been gnawing on the side of this dingy.
