Does anyone know how easy it is to fix a seal on the lower unit and what it will cost me to do it myself mine is leaking oil from behind the prop.

Are you sure it's leaking gear lube?
It could be unburnt 2 stroke mix from the exhaust...

The 40 HP twin shouldn't be too hard. Expect to pay about $35 for the kit. Try your local library for a Seloc or Clymer manual for your model and year.
