i did some math and the numbers i came up with would shave just over a hundred pounds off going with aluminum, i also found something that makes sense and doesent make sense concerning my maximum weight specs for my boat. there were two choices on transom height for my model, 16 and 20 inches, mines 16 with a 825lb capacity and the 20 has a 1000lb capacity. four inches of transom would make it safe to carry 175lbs more? you would think the distance from waterline to the gunwales being 4 inches more would be a logical reason but the only difference in both boats is transom height. and if you are interested in that motor im sure i could figure out a way for me to get it up to you to see and test it before any money being exchanged. something to think about if you or anyone else is interested???
