How to Install a MerCruiser Alpha One Foot
- 1). Push the MerCruiser's throttle to the full forward position.
- 2). Stick a drain pan under the gear case. Remove the gear oil plug with a socket set and let it drain into the pan.
- 3). Remove the bolts attaching the lower housing to the upper housing on the outdrive and slide the lower housing off.
- 4). Remove the four bolts holding the water pump housing to the lower housing with the socket set.
- 5). Slide the water pump off the drive shaft and then remove the old foot, or impeller, and pump gasket. Slide the new foot, or impeller, into the housing and place the gasket over the seal with a dab of marine grease.
- 6). Slide the water pump back onto the drive shaft and bolt it down with the socket set. Replace the lower drive to the upper drive, tightening the retaining bolts with the socket set.
- 7). Refill the MerCruiser outdrive with fresh gear oil.
