Thanks, thats very helpful.

Hi
If you decide to go for a permanently fitted shaft greasing tube you can buy them online and they are easy to install.
Hopefully the link below will work

Thats very helpful, thank you. I have never soldered anything so will go with option 1.

I do not know when Oilite bearings came into play. It is possible, I would guess. If not, you have two choices. If the prop shaft is easily removable, then periodically removing it and greasing it with a light H2O proof grease will Probably be sufficient. If the prop tube is easiy accessible and you are good at soldering, then you could drill a hole, nearto but not at, the inboard end. The hole should be a proper fit for a piece of brass tubing (ie, this is assuming that the prop tube is brass) Insert your prop shaft so the piece of tube just touchs it, then back the tubing out just a hair. Remove youe shaft. Use care not to move the brass tube. Solder the brass tube into place. you then use the ube to apply oil or grease to your shaft. That is it in a nutsheel. When in doubt, use the KISS principal: Keep it simple Simon. i would use the first approach if you have any doubts. Best of luck.

It was made by my dad i'm guessing in the 50's, would they have had oilite bearings then? I'll have to look at taking the shaft out and checking.
Thanks

It all depends... Are you using manufactured shaft tubes that have oilite bronze bearings( bushings to some), or are the shaft tubes just palin brass tubes?
If the former, you need to do nothing. Oilite bearings/bushings are self lubricating. If the latter, then either greasing or oiling the tube is advised. This can be done by periodically pulling the shaft and lubricating it, or... soldering an oil/grease tube to the shaft log. Then you can add a piece of silicon tubing and periodically add oil or grease.
