Hi folks,


A few years ago, I bought a handful of new old stock prop shafts.  What I need to know, is because I am converting all of my boats to brushless, either from ic or brushed, will the propshafts in the boats already, or the new ones still in the packets, be suitable for brushless power?


None of my boats are race boats and I'm not looking for ultimate speed.
My boats are motor cruisers between 29 and 46 inch, plus a 49 inch MTB as well.
The motors that I am looking at using will be outrunners, between 750 and 1000(ish) kv, so not really high rpms.


I have seen posts where people have fitted tubes onto the side (facing up) of the stern tube for lubrication, is this something that I need to be doing?
Or is there other lubrication of the propshaft I should do instead that would be enough?


I won't be running the boats at high/max speed for long periods, mainly scale, occasionally a bit more 


Thanks in advance for any advice.
Will

As far as the propshaft is concerned it doesn't matter what type of motor you are using. You are not going to be using high power output so they will work OK. There is generally no difference between old and new shafts, although some newer shafts may use plastic bearings instead of metal. Adding an oiler to the stern tube is useful as it does make it easier to oil. Some put waterproof grease in the stern tube as lubrication and also as a seal to stop water comeing through the tube especially if it is horizontal and below the water line. I don't use grease as it does create drag on the shaft making the motor work harder, normally just oil the inner bearing occasionally let the water lubricate the outer bearing (may occasionally add oil to the outer bearing but this tends to leave an oil slick on the pond behind the boat.)

Thank you Jim, that's the sort of info I'm after.
I have been away from model boating since I was a teenager and only now getting back into it. Because things have progressed a lot in many areas, I have much to learn.
