Lower Unit Oil has a Funky Smell like Gear Oil {80-90w},and is much thicker than 2 stroke.

Lower Unit Oil will leak from the backside of the prop,blow-by will be comming from Exhaust

Hope this helps

Not realy,I have a 9.9 that I do all the work on myself,but I turn Wrenches ALL DAY,so it`s not a big deal for me

It`s not a hard job,not sure about that exact model,but once you get your Prop off,the seal goes around the Output Shaft....

Put a catch pan under the lower unit,remove the Fill and Drain Screw`s from the side of the foot and alow oil to drain....Remove Prop,pop out the seal,clean surface, put a light touch of oil on the Seal Edge where it touches the shaft,and tap the new seal back in being careful not to distort the seal......before putting the Prop back on, fill lower unit with oil....

This should take about 2 or 3 bottles of gear oil......fill from the Drain Hole,forcing it up in the unit until it comes out the Fill Hole,then Instal the Fill Screw....then the Drain Screw......I know it sounds BackAzzWards,but you get no Air-Pockets.......check the Seal Area,if no leaks,install the Prop,put it in Nutural,spin the Prop by hand a few times so that the oil that you put on the seal is spread around the shaft to assure the seal doesn`t get torn by a Dry Shaft.

Taking the Prop off from time to time,and removing any Fishing Line that gets wrapped up behind it,will keep ya from having to do this seal as much

I work at the corner of 17-92 and 436 {Car Cool} if your close to the shop,grab the Seal and Oil and swing in,we`re SLOW,I`d be glad to show ya how to do it
