1997 70 horse prop

[seminol7]

Just wandering what kind of extra performance a stainless prop would add to my boat.Some say it would add about 5mph.but I fish stumps and shallow water is it worth the security of the alum. prop. only breaking the prop. not the shaft?

You need to know what the current prop you have is doing. You need a tachometer to make sure you are running at the optimum rpm's.

Not all stainless (very few if any) props will increase optimum performance.

The last part of the equation is the set-up of the motor combined with the hull type and weight.

You should be running a wide open throttle rpm of around 5500....... where is it now with the current set up?
