Sounds like the crankcase breathing hose, and yes the crank case may be over filled with oil and it is overflowing. Or the oil seals may be bad and in need of replacement. Check proper oil level first and go from there.

2001. What would cause oil to leak from somewhere on the driver's side of the motor?


Could be valve cover gaskets. The oil sending unit will also throw out a lot of oil.

Oil leak


There is a timing cover gasket behind the water pump.
You may have to clean off the block to find the leak. Mechanics can use dye in the oil and a black light.

Have oil leak not heavy, but it leaks any answer were it could be coming from..


Valve Covers, Head Gaskets, Oil Pan Seal and a number of other spots. You'll need to clean the motor with Gunk Engine cleaner and then look for the largest build ups of oil and crud to get a better idea where it is.

Replace water pump impellor 15hp yamaha outboard . how to remove lower leg.


Put the motor in neutral.On the leg of the motor there is a little side cover plate.Remove.Undo the bolts.This is the gear change linkage.At the cavitation plate,there is 4 bolts.Remove.If the lower housing does not drop,give it a soft whack with a soft hammer.When dropped,you will see the prop shaft and the gear linkage.Lower it all the way out.Its easy to work on if you put the lower skeg in a vice.Take the water pump apart BUT!!! have a look at which way the impellar blades are pointed.Grease the new impellar as you put it back in and turn it at the same time to get the nodes in properly.Heaps of grease to protect all the bolts.Makes it easier next time.Hope this helps
