Hello Paul, you could but as you will be taking the thruster out, why not do
the simple job of replacing the bearings with new sealed ones?
They are not expensive. All you need is a puller to get them off
and a tube to tap them back on if you don't have access to a
press. You will find that the thruster will sound smother
afterwards. Amel now use sealed bearings or so I have heard. Regarding the play in your hub, please note that the stainless sleeve does not extend much beyond the lip seal. (See my photo in the photo's section), so the pin does not go through the sleeve. Sounds like you need to replace the hub. They do get sloppy after much use.

From a maintenance point of view the sealed bearings and replacing the gear oil with grease sounds interesting. Given that both the seals and the more viscous grease will increase the friction I am curious if there is a noticeable drop in RPM during use? Has anyone measured the amperage increase after making this change? If significant one might need to reduce slightly the max run time due to heating.
