At the top of the impeller housing there is no seal where the driveshaft passes through so some water will make its way through. I have had housings that were saltwater corroded at the driveshaft opening that had to be scrapped.
A good seal at the water tube grommet, clear passageways, a good housing and impeller, and you should have good water flow. Maybe run the motor and observe the spent cooling water. The OMC 10 hp should pump a lot of water.
