Re: yamaha 150 4-stroke prop?
I'm not that concerned about speed but I am concerned with making sure the rpms etc. are right for the life of this new motor. If others with 20 footers are getting 50 mph at WOT (5500 + rpm) how much of a difference does the alum prop and the mounting hole location make to me? 40 mph is fine with me. Is it worth messing with the mounting holes this season (it's become too short already).
