what prop should i use?

[lake_time_2]

Hi,<br />I have a old (’73) Aqua sport fiberglass center console boat with a 90 hp 1989 mariner motor on it. I am thinking about getting a spare prop (or a better stainless one) and wondered if anyone had a suggestion on pitch? The boat is used in salt water for fishing.. Not after super speed… more engine life really.<br />Thanks in advance as always.. Dave

17 or 19 ft. Aquasport?

Sorry. feel pretty dumb not posting that!! It was sold as an 18? But looking at the way it takes up the WHOLE SHOP i think it is a 19. Thanks Dave

Hi Lake,<br />Looks like a 13-1/4 X 17 would be a good starting point with an alumnimum or stainless. Check out the Michigan link below and use the Prop selector:<br /><br /> web page

What are the specs on your current prop and what rpm are you getting at full speed?
