Yamaha 25HP Portable motor leaking a bit of oil

Recommended Posts

Looking for some advice.

.. I took my boat out last night and when i went to flush the motor this morning I noticed about a cup of oil had leaked from the bottom of the motor. Is this normal? It operates fine but having had the motor for over 5 years this is the first time this has happened so not sure

nah mate not normal. it will be ur gear box oil. i think a seal would have gone. wheres it leakin from? if from the screws where u change ur gear oil from u might have to replace the gasket on the screws. if out of the holes its sometimes the seal around the horse shoe. best to get it looked at.

if the oil is black and leaking from the front or rear of the prop u probably just added to much oil to the fuel mix

if the oil is milky it will be a gearbox seal
