Does anyone know of anywhere I can check out to find the weights of outboard engines? Specifically a 87 Force 50hp vs. a 75hp Mercury (year not known..model # in pic looks like OB013101)looks to be about the same age from the picture. Any help is really appreciated! ![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
