Billy, generaly speaking it isnt worth the $$$ to upgrade a new engine on an older boat. If the engine is performing well, personally I would keep this engine until I bought a new boat/ engine combination. The new Optis and the Pro XS engines are the stuff if you are to buy a new product. Not only is the performance exceptional, but the fuel economy over the EFI engines is very noticable.Last edited by Basstar on October 14th, 2007, 3:54 am, edited 1 time in total.
