I have a Mercury 90 HP outboard engine. I need to change the oil and filter but cannot take the boat out of the water. What is the best way to do this?
If its a 2 stroke, there is no oil to change, if its a 4 stroke, you can pump the oil out with a small diameter tube pump.Depending on the motor, you can get it through the dipstick or the fill opening. If you need to change the gear oil, there is no way to change it while in the water. Stop by a marine supply store and get some oil absorbsion pads (diapers) in case you happen to spill any oil into the water
Turn The Boat Around So That The Engine is Nea The BankrUn Bolt The Gear Box From The Engine On The Bank,
Change The Impeller On Dry Land Replace Gear Oil and Re Fit
The Gear Box.
The Engine Does Not Have Oil Change Unless It Is A Four Stroke.
If It Is The Drain Plug Is On The Side Of The Mid Section And Can Be Drained With Leg Trimmed Up About Half Way
Sorry This Is Best Way.
