1972 Evinrude 9.5 HP, Model 9222<br /><br />There is a small hole, about 3/16 inch diameter, in the underside (bottom) of the cavitation plate above the prop. The hole is offset about 3/8 inch to the right of center. <br /><br />After running the motor in a garbage can of water yesterday, some (a little - drops) oily moisture leaked out overnight as the motor set upright on a motor stand. <br /><br />I can only guess it's a drain hole from the exhaust cavity.<br /><br />Is the hole supposed to be there?<br />What's it for?<br /><br />Thanks,
