Any info on maintaining an outboard motors,especially concerning engine oil and lubricant in lower case?

I just bought a 65 hp mercury outboard motor w/my boat and the plug in the lower case was taken out and stored in a bottle. this is my first boatAny info on maintaining an outboard motors,especially concerning engine oil and lubricant in lower case?
There should be two plugs in the lower case. Take out the topone. Get ne3w marine gear oil. after you get it open, stick nozzle into bottom hole. Queeze bottle untel oil come out of top hole looking new. put bottom plug in and install top one. Now your ready to go. When you store your motor for the winter, do this over again to insure there isn't any water in the lower unit. Cause if there is, it will freeze and bust the lower unit.Any info on maintaining an outboard motors,especially concerning engine oil and lubricant in lower case?
I add Info as I think.


This is a good Engine for the size. Use a 50:1 Fuel mix. Most times it like a 16 ounce can to 6 gallons gas. As stated above find the top plug. It on the Right look from back of Engine just above the flat part, it about in the Middle, no other screw, about 12-18 inces above the bottom screw. Yes!!!! That it, you see it then, good! You can fill as stated above. What I do is take a 1 gallon Yard Sprayer and remove the spray wand. May want to round the end a little to seal better. Put your Lower Unit Lube or a Good Rear End Lube for cars (Ask Auto Part store, some know what the people using for their boats). Put the Lube in the sprayer and pump it up. Then fill from bottom until the lube come out at the top, this keeps air moving up and out. Put the screws in and you got it. Check the screws for seal damage too. Out boards are easy to maintain. In winter you can Run out of gas and it should pump up next spring with fresh fuel and start. OR, Get some ';Ear Muffs'; they a Muff looking thing for running the boat out of water connected to a garden hose (Never run for long periods without water, Impeller over heat and that not good). Wal-Wort sell them. Every week start and run the Boat (Put fuel Stabilizer in for winter. DO not run at very high RPM out of water. May want to Charge battery once a month in winter. STORE with Engine down if outside. Rain get in a pocket area behind the prop and if it freeze it may crack the Housing, keep down the water stay out. When you start, check the little ';Pee Hole'; Just below the Cowling around the Engine. Be sure water come out, it just an indicator that the Water Pump Working. If, it not Pee check first if it is Clogged. Dirt Dobbers love these little holes.


Steering Cable @ Engine. DO NOT GREESE THIS! It just pockets water and rust up. IF, it been Greesed, get a can of Carb Cleaner and clean it off best you can. Spray with a Silicon Spray. I just kept a can under the cables so it not blow out and turn Steering until it all way out and spray it good once a week/month not matter, what feels best to you, a can last a long time.


Control Box. The biggest problem here is the greese inside get old and hard and then you have a part wear out. IF, you can learn how to open and clean and add fresh greese (Lightly coat) about every 3-5 years you never have a problem.
