    I have a friend that has a Solas 13/19 impeller that I can get cheap, so maybe i try this first before the ECU. With taxes and customs to norway this part will be over 1300$ in total!
    The 13/19 is closer to the area you want to be. I tried running the 11/15 with nothing but trouble, it went 65 at 8,500rpm. Went with a taller prop and brought the rpm down to 8,000 and picked up a ton of speed. You may also want to look into reducing the nozzle diameter that helped with top end speed.

    Perhpas you can share the cost with some friends?
    A single MapTunerX device can hold tunes for multiple Yamaha. Buy the box alone and import it.

    Then from the GH online store directly purchase 1, 2 or more tune licenses as needed, one license per ECU serial number.

    The tune licenses are entirely electronic, so no import duties/taxes/etc?

    Hi.
    In Spain we also pay a lot of money in Taxes and Customs. It is an abuse.


    I have two questions ...


    When increasing the rpm to 8,300 or 8,500, the engine loses reliability? Is it very harmful?


    And, approximately ... How many cv is of increase?


    Thanks from Spain and sorry for my English.

    Complete agreement. I use a 13/19 solas and have a 71 mile on lake and 73 on river, rpms about 8200-8300.
