Product Overview

This is the driveshaft mounted impeller used on the small portable motors, the ones that live on tenders and get run in shallow water. It only fits the versions with the impeller on the driveshaft, so check where yours sits before ordering.
The 2 to 6 HP Tohatsu block is the motor Mercury and Mariner sell as their 2, 2.5, 3.3, 4, 5 and 6 HP four stroke, which is why the 369-65021 and the 47-16154 families both appear on this part. Sierra lists it as 18-3098.
