Motor Help!!!

[jhanks50]

SO i have a 93 Mariner 40 hp tiller. I used it about 1 and a half days ago with no problems..tonight as I am letting the dog out i notice a large pool of oil on the driveway leaking from the motor and all pooled up in the water catch in the rear. The boat was not touched since the last time it was used...so far I have not been able to find where it is coming from and everything looks to be ok (other than oil everywhere...)anyone have any ideas on what could have happened? Im taking it in tommorrow to have it worked on but i thought i would pose the question on here as well?

Thanks

Are you sure it's oil?

It could possibly be exhaust, unburnt fuel oil mixture leaking down and pooling up.

No it is definatly the oil...my motor has a separate area in the motor to put in the oil (no mixing) and i got out there to try and stop the leaking and watched the level in that container drop until there was nothing left in it...

Did you check the hose, connections, and oil filter for leaks. Or maybe a crack in the oil tank. If its not coming from any of the above your oil pump would be the next in line.
