Decent kit. Doesn’t include all parts shown in photos.
Size: 75-250 HP
I purchased this kit to replace the impeller and necessary components on my 2006 Johnson 150HP V6 Outboard. I SPECIFICALLY ordered this kit because it showed the shift shaft seal in the photos, where other kits didn’t not. This kit DID NOT include the shift shaft seal, as pictured in the photos. All the other parts fit well. The o-rings could fit a bit better. The o-ring seal for the impeller housing was a bit of a poor fit and could be made better, but still worked when glued in. Get what you pay for, right? The parts worked and replaced what I needed. Really would’ve liked to change that shift seal while everything was apart.

Looks very good quality to me.
Size: 85-300 HP
Everything looks good quality to me. I find it odd that the people leaving bad reviews with pictures of broken and melted impeller, when you can clearly see the brass on the inside is brown and dirty like old pennies and mine is shiny new. It's almost like the took the pictures of the ones they replaced to get a refund and a free repair kit.
