Aluminum props are best in rocky waters. Stainless props don't
resist rocks much better than aluminum does, are 4X more expensive to
replace or repair, and they're more likely to damage the engine when
they hit something.

So why don't I just stay away from the rocks? Because rocks are
everywhere on northern MN lakes like Vermillion. Rockpiles suddenly
appear in what looks like mid-lake with the sonar saying 30 feet.
It would take years to "learn" that lake (40,000 acres, 24 miles long,
313 miles of shoreline) and I only visit there once or twice a year.

The AL (pot metal?) props are useless - I had one fold up hitting a rotton 2
