If you know your idle revs, lower unit ratio and prop pitch, it is easy to calculate the theoretical speed (not accounting for slip which would be small at idle speeds)

Seasick, I would have expected slip to be worse at low speeds. Good to know. I'll have to check what my numbers come out to be with what I have now for comparison.
Dennis, we use 2 bags with our ox66. It's a bit of a PIA because the engine doesn't like low rpms for long periods of time and it really impacts handling. It would be nice to get away from them entirely.
...and I don't want a kicker. A trolling plate helps, but it really kills efficiency even with it up. I'm hoping to find a less is more solution!
An etec might work because the idle speeds are a lot lower, but the inconsistant quality and rigging issue horror stories is a turn off.
