    Yamaha M vs T series (vented on 225 OX66)

    How do these run pitch for pitch?

    Pitch is the same but the T is a larger diameter prop and harder to turn than an M model.

    I guess I should have asked should I go smaller if switching to the t series or stay same pitch? I know it all depends, but I am easily turning a 27m to 6k and don't know if I should go 25t or stay with 27 for the T and bring rpm down a bit. I can't run WOT now without over revving but I think my prop might be FUBAR.

    Whats your WOT speed and rpm's with the 27M your running now. Does that motor have a 1.81 lower unit

    Sent you a pm. How do I verify lower unit ratio? According to what I've found, it SHOULD be 1.81
