My deciding factor would be if you fished tournaments. If you did, I would go with the larger boat. If you fish for the fun of it like I do, stay with what you got and upgrade the electronics.You say you would upgrade the trolling motor, what #thrust is yours, not powerful enough When I bought my boat, 17 ft. Lowe, I was not really looking for a large motor, maybe a 40-60. The boat I bought has a 90hp Johnson, It will run fast but most of the time I am at 3/4 throttle. I launch close to where I am going to fish. Have you priced a new boat, sure you have, they are proud of them, couldn't believe the price but then again I cheap.
