Bob, is your starter, rigger, funder battery a dual
Purpose… I read that regulars starters will not last as long if drained and recharged running big motor would keep it topped off and mitigate that. I replaced my starter battery that came with new boat, I  put in dual purpose starter/deep cycle for start and riggers can use it as back up for garmin if I drain my dedicated finder battery they fit next to each other in same compartment.

The crank battery came with the boat and was installed by the dealer.  I doubt that it is a dual purpose battery.  I would think it is just a marine crank battery and should last me 5 or more years.  If it fails for any reason, I will replace it with a marine, deep cycle AGM.

At least on my 300 ProXS, the prop is mounted via a rubber "Flo-Torq" hub that will "spin" inside the hub of the prop if it were to contact something solid. This was designed because of exactly what you said - in the old days when a stainless prop was installed straight onto steel splines, it was an expensive game of "what's going to break first?" if you hit something. The rubber prop hubs these days are similar to a shear pin on a snowblower - a designated failure point.

I believe you are correct about the rubber guts in todays props.  But I'm still gonna stick with the 4-blade aluminum prop on my engine.  Too darn old and set in my ways to change.
