Re: getting started
You shouldn't make any changes without your present prop,max rpm and speed.At the least you could get poor results,at the worst you could ruin your motor.
Yes a stainless prop will usually improve performance but without the specs it is a crap shoot.You should also optimize your setup as discussed many times by myself and others.Setup alone can net 2-3 mph depending on your present setup.You could get something like a tiny tach easy install,reasonable price,could be used on any similar motor without regard to poles.
