This hub kit is easy to install. If you haven’t changed a hub and prop before this hub kit comes with instructions.

Bought this hub to go with one of their props. You can definitely tell the difference between Turning Points hub quality and others that are out there. Turning Points actually weigh something and install very easily!

Expensive adapter, but it should be buy once and reuse when installing new props in the future. Well made, fit correctly, easy install.

Worked perfectly to install my new Turning Point Express Mach4 on my motor. Make SURE you research the exact hub to fit if you have a Command Thrust lower unit, usually it's in 'fine print' which exceptions you have. This is on a Mercury 115 ProXS, with Command Thrust. I would deduct 0.5 point for the installation paperwork. You're better served to find a decent YouTube video! But, it was a perfect fit.

Very easy to install on my 2000 Bayliner Capri 1950 CL with mercruiser 3.0L Sterndrive.Haven't tried it out in the water yet but looks solid and hope it will help prevent damage to my new propeller. I went with this 14 dia. X 19P which was recommended by the TP wizard online.Will update this review when I take the boat out next month.Quicksilver 822777Q1 Aluminum Trim Tab Anode - Mercury or Mariner Outboards and MerCruiser Stern Drives Using High Rake Propellershttps://www.amazon.com/dp/B000RZSJJ2/ref=cm_sw_r_cp_apa_fabc_Tya3FbJYA39K6?_encoding=UTF8&psc=1Turning Point Propellers 21501930 Hustler Aluminum Propeller 4-Blade, Blackhttps://www.amazon.com/dp/B003MF0GJ0/ref=cm_sw_r_cp_apa_fabc_xAa3FbWAVJZY4?_encoding=UTF8&psc=1

This is a 5 star hub and it would have got 5 stars had the prop nut not come with a super weird defect. I could fit my 1-1/16th and 27mm sockets (same size for all intents and purposes) on from the bottom of the nut but the top of the nut bulges just enough to make it impossible to put a socket on it which is problematic given that this is a nylon lock nut which can only be installed one way and it bulging from the top makes it impossible to tighten. Luckily my oem nut will work just fine but I was really hoping to have an extra nut afterwards in case I do something stupid like drop the nut while working on the boat in the water. Other than that the hub is great. Slapped hub in. Put thrust washer behind it and gave it a couple whacks with a rubber mallet so the thrust washer would seat flush, put some grease on shaft, plopped prop on, put gear looking washer on followed by pronged washer and lastly the prop nut, tighten to 55ft-lbs, bend 3 tab back on pronged washer into slots in gear washer. Easy peasy. Would have been even easier had the nut they included worked the first time around but other than that I have no complaints.
