    Help with Yamaha M series

    How do I get a 25p Yamaha M series to fit onto a Merc 225 efi? 203 had a Trophy 26p with a flo torq hub system. I would like to run this new Yamaha prop, but the prop shaft splines are showing when I slide it on. Thanks in advance.

    Use a Yamaha thrust washer but cut the flange off of the back of it so it doesn't contact the prop shaft seal. Use basic Mercury stuff on the other side. I'm running a 23M on my Merc, works like a charm.

    Have a 25m that worked great on my boat but I threw an ear off. Seems it happens a good bit. Lift was great at higher speed.

    The yamaha T prop is better suited for your 225 merc. Its a heavier made prop for big block engines. The M series is for 2.5 size motors. A tempest would be as good or better than the T series.
