Easy to install if you watch some online how to videos.
The water pump kit worked great on my 35 year old, 2 stroke, 100hp, Mercury Outboard.

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.
