Will my propeller take a hub kit?

[Kybertek]

IMAGE A shows an empty hub cavity, IMAGE B shows one with a rubber hub installed. If your prop looks like IMAGE B, you will need to have the hub pressed out in order to install a hub kit. here

Another indication that the prop will take a hub kit is if it ends in either "A45" "A46" or "X". For example QA1912X and 48-832828A45. If it ends in "A40" it MIGHT take a hub kit, but you have to check if the hub cavity is squared. An "A41" and "A5" or parts ending in "R" ie, QA2120R will never take a hub kit. [links]

Propeller blades are sharp. Handle with care. Always ensure X2E is turned off before replacing the propellers to avoid injury. Do NOT attempt to replace your propellers while it is powered on. Doing so is an extreme safety risk and may lead to serious bodily harm or injury. more

If you are using a late-model Mercury propeller with a Flo-Torq hub system, also keep a matching Flo-Torq replacement kit on the boat. The Flo-Torq hub is designed to be sacrificial. In the event of a hard strike to the propeller, the Flo-Torq hub gives way to protect the prop shaft and gearcase from damage. If that happens, the propeller might still be functional, and you can get back underway by removing the prop and replacing the hub components. You can also replace a damaged propeller that uses a Flo-Torq hub with a spare prop that uses an old-style rubber hub, as long as that prop fits your gearcase and prop shaft and you have the correct hardware required to install it.

If your boating takes you far offshore, it’s more critical that the spare prop is rated for the power of your engine and is of a size similar to your main prop, so that the boat is able to get on plane and cruise back to port at an efficient speed. Yet even for offshore duty, a less-than-ideal prop can be a perfectly adequate solution.

For general lake and inshore boating, your spare prop really only needs to be “good enough.” You can carry an affordable aluminum propeller as a spare for your more valuable stainless steel prop. Many boaters use a previously repaired prop as a spare and a new prop as their main prop, even if the pitch on the spare is an inch or two larger or smaller than the main propeller. The mission of the spare is simply to get you home.

It’s a good idea to learn to install your spare prop on dry land or in the marina just to make sure you’ve got all the tools and hardware you need. When you remove the main prop, pay close attention to how washers and spacers are installed so you can put them back in the same order, facing the proper direction, when you install the spare. Before you begin removing the propeller, always remove the key from the ignition and disconnect the emergency shut-off lanyard. [links]
