  1. I have ordered a month ago the 300R at Ellis Marine in Brunswick Ga . Is there any chance in a earlier than later delivery date???? Will this come with 1.60 gear case or the 1.75 . I am going to install this motor on a 21 foot Liberator please respond
    Thanks Donny

    1. Donny,

      As your order stands, it will not have the 1.60 ratio. You can have your dealer contact Mercury Racing Sales and change the gear case option, we are happy to help. Your delivery date is our best estimate at when your motor will be available, we apologize for the long wait. Thank you for the order and congratulations on the upcoming Libertor!

    1. Rick,

      At this time, the stand alone gear sets are not availbale for purchase. We do plan on making them available in the future, keep an eye out for an announcement on the Blog!

    1. Leon,

      For applications running in excess of 90 mph, the 1.60 ratio offers a much better propeller selection. Think of the 1.75 as essentially limiting top end speed. Some applications are running the highest pitch Bravo and MAX5 propellers that Mercury Racing offers and are still near or on the rev limiters. Switching from the 1.75 to 1.60, guys will step down 2 or 3 inches in propeller pitch to achieve similar RPM. Having the availability to run a 31 or 32 pitch propeller is a lot more appealing than a 34 pitch. This problem is much more apparent on the 300R because the RPM range is limited to 6400, whereas on the 400R it is 7000.

      1. Thanks for the reply. I am strapping the 300R onto a 19.2 foot bass boat. I normally run relatively light. What prop would you advise.

        Currently I am running a 225 proxs but I am struggling with bow lift with fury 4 26p ( 5950rpm) I am testing a 25p promax to improve the rpm and bow lift.

        Thanks again
