Hi officer, welcome to iboats and outboards. I know you're new, but a little help with what brand and kind of engine you have would help.

But most, if not all, makes of OMC have the drain and fill plugs on the lower unit, you will see two big slotted screws, those are the plugs. The drain and fill are the same plug and will be the lower of the two, the upper one is a vent for draining and you also use it to tell when the lower unit is full.

You drain out from the bottom one and re-fill through the bottom one also, until it comes out of the top hole.

my motor is an old jhonson 5hp TD20. the bottom plug is marked drain but i also fill in the same plug or can i fill it throught the top plug? and what type of oil do i need to use as it is not grease?

Re: new to outboard motors (TD20)

Remove the top and bottom plugs. Fill through the bottom so there is no air trapped. (Youll need a $10.00 pump from Boat us or other for this) When its full and leaking out the top put in the top plug then remove the pump and quickly install the lower plug. Some oil will leak out but it's OK. You should replace the little nylon washers too. Evidently there only intended as a one time use (but I've used mine for two changes with no problems)

You'll probably need 90 weight oil but I really dont know what the little guys use. Someone else will tell u for sure

Wow! you might be new to outboards but you have an experienced motor. They were made from 1946 to 1949. I use Lubriplate 105 grease in mine. Make sure you use 1/2 pint of oil with 1 gallon of gas (16:1). Those older ones need it. You can also find help here:
