When I was putting my boat away yesterday I noticed a smear of gear lube on the lower unit. Close examination revealed a crack about an inch long in the housing below where the anti-ventilation plate is and towards the front. I have no idea how this happened. There is no sign of any impact, and I faithfully change gear lube before storing the boat for the winter. (engine is an Evinrude 88spl) Has anyone seen this happen before? To repair it I plan to drain and remove the lower unit, vee out the crack with a die grinder, and take it to a shop I know of that does welding on aluminum. Then I can grind the weld flush, repaint, and the repair should be invisible. Would anyone else repair it differently? This should be a strong, permanent repair. I'm just happy I found the crack before this became a major failure. I checked the area where the boat is stored and found no evidence of gear oil on the ground so I have to think this just happened yesterday.
