[Norman Castle]

I've built three Springers so far.  Two of them have 6" propshafts and one has a 5".  The 6" ones don't have an oiler tube on but the 5" does.

Both boats with the 6" shafts seem to run perfectly happily with the shafts greased with ordinary lithium grease.  I haven't yet needed to re-grease either of them.

With the 5" tube, I tried running on 5W30 motor oil, but gave up as it kept leaking out, so that's now running greased up like the others.

I'm about to start another Springer, which will have a 5" propshaft.  In view of my experience so far, why would I want an oiler on this one?

[Captain fizz]

you wouldn't.

[Norman Castle]

you wouldn't.

That's what I thought, but seeing as how I don't really know what I'm doing, it made sense to ask

I agree with the Captain Norman - just give it a squirt it up its rear - I use silicone and my Springer loves it.

My 3 boats, one a 7 year old Springer do not have oiler tubes.  I regrease the stuffing tubes yearly with white waterproof grease (Lubriplate).  Never a leak, never a problem.

The subject of lubrication of prop tubes has been discussed (and argued) many times before, the sum total of which seems to be - do whatever you feel is appropriate for you. Personally, I always fit greasing tubes to my prop shaft assemblies and use outboard motor grease because of its water resistant properties. That method suits me and I will continue to use it, but I'm not suggesting that everyone should do the same, it's a personal choice. Some argue that grease puts a strain on the motor, which it probably does in a small way, but for my relatively slow moving models, any such added load is so minute as to make no noticeable difference. High performance boats may be different but I don't know as I don't have any.

I don't get why you are trying to justify your decision to yourself, just do whatever you prefer! All my boats have oiler tubes, none leak, I'm not arguing (again) the pros and cons of either, its personal choice, however if the oil is leaking out, does that not tell you that your bearings are not good, otherwise....they would not leak.  Put grease in if that is what you want to do, but it will not stop the issue that the bearings are quite possibly worn, maybe due to a bent shaft, incorrect fitment, misaligned drive train or just worn. I would be more inclined to find out why the oil is leaking
