Good impeller kit
Great kit for impeller alpha one gen two outdrive. The only thing that was missing is the instructions as a reference.

Outboard impeller replacement kit.
This kit was for a 1999 Mercury Force 75 hp outboard motor. I purchased used and had not been run for a year. Impeller was hard and not flexible enough to pump water. The kit fixed that problem and the job took about 2 hours to complete. (I took my time). If you don't have a shop manual look for YouTube videos. I watched several and found one that matched the motor I was working on. Made things much simpler.

Excellent product
The water pump kit fits perfectly well on my 1997 Alpha 1 Gen+ Stern drive. Quality looks good and at reasonable price. I run the motorboat for 20 minutes and the water recirculation was constant

Maintenance for Sea Ray 175 boat
Had everything needed for replacement of lower unit impeller. Should be replaced every 3 to 5 years.
