I have a 1991 Steigercraft running a 1987 Envirude 90hp motor. Still has the original setup with an external oil reservoir pump mixing oil and fuel. After changing the lower unit gear oil, it has been leaking a fair amount of gear oil from a tiny "weep opening" on the lower half of the drive. Could this be normal? If oil is leaking out, i would guess salt water could weep in??? Additionally, when running on muffin the driveway I am noticing a small amount of water being pushed through the seem from the top and bottom half of the drive. I have read some responses which say the water could be normal because the house hose has a stronger water pressure than needed, but I have also seen responses stating that the small tube within the drive could be broken. Thoughts on either situation, or both would be greatly appreciated!!!
