15 ft runabout 45 hp Top speed???

[redhouse7]

I've got a late 60's fiberglass runabout (pretty generic) with a 45hp motor on it, and wa wondering what I should be able to get for a top speed out of it?

I had a 15ft trihull with a 50hp that topped out at 28mph by gps. Yours should probably be right in that neighborhood.
