There is 2 screws on the leg.One is below the bulge of the g/box and the other is just near the cavitation plate.Usually about 12-15mm across and flathead screwdriver.(usually)Pull out the bottom screw,then release the top screw.The oil will flow out.Good idea to replace the washers on them.To refill the g/box,you have to pump the oil in from the LOWER plug.The bottles the oil comes in ,have a tapered nozzle and you squeeze the bottle untill it comes out the top hole.You fill the oil from the bottom up.(no air bubbles in the g/box)Replace the screws.Job done.Take the prop off and make sure no fishing line on the shaft and put some grease on the shaft and replace.Hope this helps

How do you change the gear lube in a Evinrude Triumph 70 hp outboard motor?


Hi .
There should be two flat screws on the lower leg, remove the bottom one and then the top.have the motor fully down position to drain, when filling with new oil it has to be done from bottom to purge the air out, Gear box is full when foil comes out top screw, install top screw and then bottom, you'll lose a bit of oil when bottom is removed install . if not sure have a look on YouTube, it should help you out.
Good luck.

Tip

Outboard motors


Keep the gas in your outboard new/clean with new oil every 6 months..Keep your motor covered when not in use, Dirt dabbers (dobbers) will build nest under the hood and break loose and ruin your motor, ,,Change your water pump and thermostate every year when motor is used a lot.....Dont run stainless steel props on small hp motors ,when you hit a log it will bend your prop shaft costing big $$$ to replace..Ck your lower gear oil if water is noted ,replace lower seals...Dont buy used motors unless you run a compression ck....ck for water in gear case , Dont buy 4 strokes to heavy to slow to many parts AND are being replaced by fuel injection 2 strokes .... Dont buy FORCE motors not made by mercury no parts being made and or extink and pure junk . Etex best motors , .

Why won't my Mercury Optimax 150 outboard start up. Engine turns over just fine, and there's 2 beeps to the throttle box.


I usually do cars and trucks, but if you are getting an electronic beep, you might go online and refer to an engine Manual for what you own. You may have a low oil lockout for the crankcase on a 4 cycle or a low oil cutoff alert for a 2 cycle with an automatic oil feed mixer. Some transition of inboard-outboard technology to outboards can include tilt lockout so that you can not start up in gear. Most prevent the starter from turning, but could keep the engine from firing if they want to wire it that way. With the "beeps" it would seem to be a Code.

When do i need to change gear box oil


Every year or once every 50 hours. Use only fully synthetic gear oil. Fill from the bottom drain screw until oil comes out upper screw. Put in upper screw and then lower screw.

Gear shifter locked in forward gear


If the gear lever is loose,it's the gear connection rod that you disconnect to do a g/box drop.If its not loose, drop the g/box off the leg and the first thing you find might be the problem.A loose bolt,a jammed shifter.It will probably be a connection problem than a g/box problemHope this helps

Gear Lube leaking from Prop


Keep an eye on it and put a bucket with paper inside under the motor. You want to know whether the oil is burnt oil from the exhaust or gear lube. You should be able to tell from the color of the oil. Its kind of like soot in a chimney, the exhaust goes through the prop with the oil you added to the gas.

Need oil change in water


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
