Changing 170 outdrive impeller

[spareparts]

leave it in forward gear, the shift hardware all aligns in forward gear. Drop the lower unit,dont forget the bolt under the trim tab. R%R the impeller. Prop turn counter clock wise viewed from the rear to keep it n fwd gear. Spin the prop to get the splines aligned, Bolt back up, fill with gear lube from the bottom

It took so long to get a rebuild kit that I'm not sure about some of the stuff and the kit has a ton of extra parts (must be for several versions of the pump).

Can anyone email me a blow-up diagram of the Alpha 1 Gen 1 with the water pump? All I'm finding online is Gen 2.

Thanks Spare - I recall the keep it in forward gear part now.

Thanks again guys:

Tunaman - the diagram kept me on the right track reassembling the pump.

Spare - I'm glad you reminded me about turning the prop counterclockwise to line up the spline and hold it in forward gear - went together very smoothly.

Got it back together and ran it on the earmuffs for a half an hour and it purred like a kitten and held about 140 degrees on the temp gauge. This is the one that was running for 20 minutes and losing RPM until it died.

I can't wait to get it on the water for a real shake-down but it looks like it's fixed.

I have to replace mine soon , never done it before ( always paid somebody ) so any words of advice is appreciated..keep it in drive seems to be key for the shifing linkage?
