Foot oil leaking

[brim_buster]

My buddy has a Evin 150 model #E150ILEUC that when he tilts the motor oil will drip by the prop.I did some research and the only thing I saw was 2 o-rings called propeller shaft housing o-rings. pn#0305123. If those are bad could that be whats causing the leak? Thanks in advance for you help.

Sure, if they are bad. But they probably are not bad.

What else should I be looking at?

I doubt that 305123 is leaking.------Pressure test the gearcase to find leaks if there are any.----Very important to maintain the lower unit as parts / service are expensive !!

Smell the oil...if it has a gas smell it the carbs unseating and running down exhaust tube dissolving carbon turning it black

if oil goes out some water must be entering the GC do you have any water in the GC oil ...drain and check

These units are expensive.-----Working on a 150 FHL case ( $25 invested initially ) for myself.------$6675 to buy it new.----Working on another one , regular 150 / 175 HP that stripped the gears as well.----These units are not as good as previous V-6 cases, in my opinion.

The part labelled #27 and called "seal" ??

Well # 17 is the o-ring. and 27 is the propshaft seal.-----Pressure test the gearcase to find leaks.
