  • after taking off the prop is it normal to have oil inside the lower part of the motor cause i had oil dripping out from behind the prop before removing the prop??????????????????

  • @liv4daoutdoors No, this is not normal and very likely indicates the seal on the propshaft has failed. I suggest bringing it to a marine outboard mechanic. I also suggest NOT storing the lower unit without oil. Thanks for the question.

  • It's better to take the whole thing off and clamp it on to a vice, that way its completely vertical and makes the levelling a lot better. also u missed an instruction, u should always leave 5-10 minutes AFTER it has COMPLETELY drained because there could still be air in the chamber

  • @jacobtyler87 Thank you for your insight, whoever completely removing the lower unit just to drain the gear case sounds like a lot of unnecessary work. As far as purging out the air, that's why you fill from the bottom.

  • using a screwdriver as a punch tool BUTCHER

  • So what you are saying is that Jamestown Distributors thinks that cheap and sleazy is a good thing? I understand hiring a professional is expected, but not that kind. Go to an ad agency next time if you want to have a respectable image.

  • @liv4daoutdoors I know its a little late, but on a two-stroke, it is possible and normal to have excess two stroke oil there in a thru-hub exhaust propeller. However, continuous dripping of lower unit oil indicates a bad prop shaft seal

  • Whys that girl shutting her eyes so much and looking down? does she have cataracts?

  • I just shot my prop nutt!

  • hey thats mercury spline grease on a yamaha!!! that things liable to blow up next time you use it...

  • @wetbootsmoke Taking out and replacing a drain and vent screw is a simple task that even my 15 year old daughter is perfectly proficant at ,it is not rocket science...
