OK... I've been reading alot about having a spare prop. So, I have a question and I could be all wet, but here is my logic and I'm curious on what others think.
If I get a spare prop I want to be inexpensive, so the logical thing to do is go with aluminum. BUT, I also want to get the max performace out of my motor, so for testing purposes, is there really that much difference between aluminum and stainless? Once I find a prop size that works in aluminum, wouldn't the same size in stainless be the same?
Example: I have a Solas Lexor 15 1/2 x17 prop (Stainless). If I bought a backup prop say a 14.5 X 19 and I made my boat go 5 MPH faster and brought my RPM's to just under rev. Wouldn't it be safe to say I could go for that same sizes in stainless? (Yes, the 5 MPH is a hypothetical, but I can't let TomS boat be faSter than mine!)
