Question:

Alpha one outdrive, Water pump installation?

does anyone know the proper way to take the lower gearcase off and install a new water pump kit. it is a 1986.

Answer:

This is a simple repair but I'd recommend that you get a service manual, ether a factory manual or one of the generic Seloc manuals. The key things to do are mark the trim tab so you can put it back in the same position after repairs. Drain the oil. Removing the bolt that is in the hole at the back end of the upper housing, as well as all the obvious Nuts. both above and under the cavitation plate. Put the drive in forward gear, which takes the tension off the shift shaft. Once all the nuts and bolt are loose. Jiggle the drive and it will separate from the upper housing. You now have access to the water pump housing. Remove the housing and pull it up and off the d. Shaft. Inspect fully and account for missing impeller blades. When you re assemble Lube the impeller and put the drive key in place and put the impeller in place. Slide the housing down to the impeller. You can use ether th drive shaft or the propeller to turn the drive shaft in a clockwise direction as you apply pressure on the housing, It should slide down over the impeller. Reassemble in reverse order. Slide the drive shaft up into the upper housing turning the D. shaft using the prop to turn the shaft. Watch the water tube slip into the guide tube. Once it's in place put a couple nuts on then check the gear shift to make sure it goes F-N-R. Bolt up and fill with oil. Good Luck!
