I currently am running Yamaha 70 HP two stroke on a 16 Sea Chaser Flats and RPM aren't where there should be with my current prop. I want to change it put also am going to be putting a jack plate on.If I reprop it before I install the jack plate will I need to change the prop again after the jack plate is installed? Thanks Phil
Jackplate first...prop second...you may find that the current prop will work well when operating at a higher level than currently being run.
