    Jackplate for Mercury 450R + built in setback

    Hi!

    I hope you are well.

    I have ordered a 450R for my Phantom 25. It will arrive in October this year.

    Currently I have a 400R mounted to a Gorilla Jackplate with 4,25 inch setback. The weight of the 450R is almost the same as 400R, but the torque is much stronger.

    The Gorilla is solid as rock, but I think i should buy a newer jackplate rated for 450 hp plus. What kind of jackplate do you reccommend? Setback 4-4,5 inches.

    The built in setback of a 400R is approx 4 inches. The AMS 300R has a built in setback of 5 inches. Do you know how much built in setback there is on the 450R?

    Top speed with the 400R is 89 mph at 7,060 mph using a Max5 25. Estimated top speed with the 450R is 96 mph using a Max5 27 pitch. So the hardware need to be top notch :)

    Take care and thanks !

    Cheeers, Toffen

    I have not (yet) seen a Jackplate that the manufacturer has moved the rating to 450hp on.

    You could contact T&H Marine and ask them if they make something heavier than their "HD/VERADO" model that's rated for 400hp...
