Location: Indiana | Thanks Steve,
As soon as I get an evening without thunderstorms I will hit the lake up the street and get my rpm numbers. I appreciate your knowledge and willingness to help.
I may not have been clear. What I mainly want is a spare prop that will get me to shore in case of an emergency, and to use on our trip to Canada every few years to protect my expensive stainless one. So I was hoping to keep cost down some and thought aluminum may fit the bill. I have heard in the past that aluminum may also protect a lower unit more than stainless from a hit on a reef, so that was my main reasoning for aluminum. I am certainly not married to that idea.
I had read that if cupping/rake/diameter remain the same one might expect the 200 rpm increase with a 1" drop in pitch. I also heard that an aluminum prop , due to slipping, will reduce rpm's somewhere around 200 as compared to a similar stainless. So I was trying to figure the pitch I might try as a starting point.
So many variables for a non professional such as myself to consider. Honestly the performance is good, I just thought if I could get a spare prop AND play around with increasing rpms it might be cool. If that cant be done, maintaining rpms will work.
You are right on the holeshot. And I am one of those oddballs that could really care less about top end speed (within reason). I would trade for better holeshot than top speed almost any day of the week. |
