    2011 Pro Xs 150 oil leak

    I have a 2011 Pro xs 150 that is dripping oil from somewhere. I have had the reservoir on the side of the motor changed because the threads were broken on the cap. Then I thought maybe the oil pump was leaking but it turns out it was a loose line on the new reservoir. I’m still getting oil from somewhere in the cowling. Any help would be appreciated I don’t know what else that it could be.

    look at oil pump closely (likely) and all oil line connections

    I had it in the shop because I figured it was the oil pump. They checked it all out and found a loose line they fixed that but I am still getting oil from somewhere. Didn’t know if there could be something else that could be leaking or maybe it is just residual.

    Might be helpful to clean all the oil residue off and note if it returns. If you're using Mercury or Quicksilver DFI it will fluoresce under UV light which could help in locating leak source.
