If I had to guess I would bet you are looking at a Trophy. I have the 1952 that weighs in at around 3500#. I would also bet which ever make, you would be a little heavier. I have the 4cyl. and think it is great. Everyone laughed at me when I purchased it, told it was under powered. Top end around 32mph with stock prop. Economy is great, handles the lake excellent. Everyone has their opinions, but if using for primarily fishing, in good shape, and you like it...go for it!
