    1994 Astro 20DCX...Max Motor size

    on my 94 20 dcx it has a 94 200 Merc on it now.
    thinking of doing some major upgrades and possibly putting a newer motor on it. what I'm wondering is what the Max HP limit I can have on it. the decal is worn bad enough that I can not tell what it says.
    anyone have the same boat by chance able to tell me.

    I have a 91 20FDX and max is 200. If it would have been more I'd have put it on a few years ago when I repowered with an Evinrude Etec 200 HO.

    I think I remember that boat being a little less than 20' actual length, and I'm thinking the max hp was 200.

    I think a 225 promax would be a nice upgrade and i doubt anyone would ever question it being too big for the boat. I had a couple 300s on my 96 sp200 and it was never an issue even in tournaments if they were not restricted to 250hp.
