motor pods
rayna:
Any links to making self contained swiveling propellor power pods like cruise liners and some rig supply vessels now use.
With small outrunners of significant power should be an optioin for clever laddie to build??

There are challenges with totally waterproofing the stern gland to keep the pod internals dry - so maybe don't bother? Mount the motor vertically above the rotational axis of the pod, above the waterline, and use bevel gearing to a (permanently wet) pod. I guess that's been done?

If you need to mount the motors in the pod then use brushless motors, won't matter if the pod is dry or not. Even brushed motors will run in water. You may have problems in salt water but normal fresh water will be OK. If the motors use ball bearings then make sure they are sealed types.You would probably need to run smaller props as the extra drag of running in water will increase the load on them.As for mounting the motor in the hull and driving through gears then Schottle drives have been around for some time.

Us model submariners manage it on even the most tiny boats so.i.dont see why it's an issue or why you'd want to add a complex bevel drive.
