Reply To: what is this hole for? (upper gear case)

just drop the LU and clean out the crud with a pressure washer or piece of stiff wire and a hose.

I cleaned up a small 4hp Merc last year and you would never think so much sand and crud piles up down the LU

make certain you see light at the bottom of the LU when looking down in it while using a flashlight outside the drip hole
