All good questions. I guess my advice would be to run it as is for a while. Go have fun before you decide to upgrade. I love my 18 horse max for fishing. It swims great and is just over all fun to drive with the lighter engine it handles really well especially in water. If you want tracks I strongly recommend bearing extenders ( max track kit). You can pm me if you want. I've got three of these things. Hope this helps. Tbone
