It would be cheaper to sell it and by a 22 already with twins............there are not many made, I have one, 4 were built. I would ballpark $10,000 beyond the cost of the engine.............many more things besides what you mentioned have to be done..........transom bracing, redo the dash for additional gauges and the wiring that goes with it, re-plumb the fuel system, additional trim sending units, and with twins you will have to add trim tabs or its not going to come on plane, new shifter, new split throttle, then steering plates, tie bar, upgrade to latham side ram steering is important since you are going to be in a 120 mph boat now, and a counter rotating lower if the second engine you buy didnt come with one, the list is long.Currently have a 22 eliminator daytona with a single 300xs. Curious, if i were to buy another 300xs, what would the rest cost to do? Approximately speaking. For the rigging and another jack plate and wiring and all that hoopla.
New one Eliminator did with a 400 ran 94.That was a lot of good information. Thank you sir! I do already struggle with the hop, the boat likes some chop to set super nice through a certain speed, so i get that. All of that kinda gives me an answer for that. I just feel as if the single 300 on this boat is just getting the hull to start having fun once its at top speed. Coming from a 21 cougar with a 300x that motor was all you needed to get your adrenaline moving. This boat handles 1000x better than the 21, but i just want a little more all around power. Maybe a 400r?
