I'm looking to change my seeping oil pans.I have about 6-8" of clearance below the engines.Does anyone know if this would be enough clearance to drop the pans. I have already removed the upper gear case from the outdrives in preparation to lift the engines if I need to.My other idea would be to coat the pans with a sealer if that can be done.What kind of sealer could i use if I did decide to seal the pans.Thanks
