SS vs Aluminum?

Since I ripped off my skeg this weekend I have been thinking(scary I know :-D ) of switching to aluminum. Everyone I talk to says to do it cause it wont tear up as much when you hit something.
1) Someone once told me that a SS prop would cut the grass better than Aluminum... Any truth to this?
2) What is the advantage of SS over Aluminum?

One more question...

Porter rock guard?
3) What would have been the difference if I would have hit a rock running 25mph with one of these as opposed to not having one?

1. you shouldn't be cutting the grass
2. You get better performance with SS
3. You still would have damaged the skeg at that speed with the skegguard.

This issues' been beat to death. Do a topic search. There will be a wealth of info on the site about skegs, skegguards, alum. and SS props.

I can answer 3. Porter rock guards are made so you don't tear something up if you hit it at idle or a little faster. Nothing is going to protect you from a 25mph hit.

I agree with Tom. As I mentioned, I have been through numerous props and lower units. Whether it be aluminum or SS if you hit a rock at 25mph you will bend the shaft ($1500-$2000). Grass shouldn't be an issue due to the horse power of your motor. The real issue is whether you want to spend $400 to $500 on a SS vs. $115 to $150 on the aluminum. That is what has kept me sticking with the softer metal.

Me can't run in less than 3 feet of water so I stick with stainlesss. Even on my little Mako I run a stainless. If you are going to hit omething, you are going to have damage. My buddy hit an oyster bar with his 15hp with an aluminum prop and it still bent his prop shaft. I like stainless. Just go back with what you had and be CAREFUL cuz!

I HAVE RAN BOTH ON MY 150 MERC. FOR THE FIRST THREE YEARS I RAN ALUMINUM THINKING I WOULD BREAK THE PROP BEFORE ANY SERIUOS DAMAGE TO THE FOOT. I TOOL AROUND ALOT IN VERY SHALLOW WATER, I HIT AND SCRAPE ROCKS ALL THE TIME IT COMES WITH THE TERRITORY. I HAVE BUSTED MY FOOT TRAVELING LESS THAN 25 mph. IN THOSE THREE YEARS I WENT THROUGH 3 ALUMINUM PROPS AT $225 EACH.

I AM NOW ON MY 4TH YEAR WITH THE SAME SS PROP. I STILL HIT AND SCRAPE THE SAME ROCKS AND ETC. THE BIGGEST DIFFERENCE IS THAT I AM NOT BUYING A NEW PROP EVERY TIME I SCRATCH A ROCK.

I have wondered a lot about this topic. I have a stainless prop now and it is nice when you just "graze" a rock. But I have also bent my prop shaft when I hit a rock with an aluminum prop. The prop wasn't that damaged, but the shaft had to be repaired. I don't know what the right answer is.

Go carefully where there are rocks. Have Progressive on yo' backside. A good trolling motor with plenty of juice. Sea tow and a marine radio.

Then go fish and have some fun! :-D

In the long run SS is the best buy for your money. The problem a lot of folks have is forking out the money with the initial purchase for SS. If you're going to scrape the bottom (going slow) you will ding and bend Al. but not SS. Years ago I used to have my Al. props rebuilt, which was a lot than buying a new one every year but I've forgotton who did them. Good luck!

I agree that you get better performance with a SS prop, but for the types of fishing I do -- freshwater bass fishing and inshore salt -- I am still firmly in the aluminum camp. I would have hated to have this happen with a SS prop.

Here is what a rock (or whatever) did to my aluminum prop at about 10 mph. This is a 100hp Merc on a 19ft. Carolina Skiff. No damage other than $89 for another aluminum prop I bought on the internet. I keep the SS prop it came with for an emergency on-board spare.
