So as the title states, I bought a new(used) Yamaha 8hp 4 stroke for my RIB and didn't notice until I got home that it says high thrust on the cowl.. Can't get the exact model number since the sticker is worn away, but the motor looks new. I got a number off the emissions label but that didn't produce anything from google. So what exactly does high thrust mean on a 8hp yamaha(T8 I think)? Is it just a different prop or did yamaha put lower gears in the T8's? What can I do to make this motor work well with my 10' hard bottom Walker Bay RIB? I know it will work fine as it but I don't need all that power down low... I'm not a tow boat lol. I like to use my dingy for sightseeing a lot.
