FUEL ECONOMY ?!?!?!?!!?? — WE DONT NEED NO STINKING FUEL ECONOMY !!!!!!!!!! ( LOL ) — In any case , fuel economy will be mostly irrelevant , since it will be somewhere around 4 miles per gallon . — Jackplate height will be determined by your load and performance requirements . — All boats / motors are different , even if from the same manufacturer . — This is where you get to ” play ” with YOUR boat . — Good starting point is where the jackplate was set at the factory , which is probably 1/2 inch above flush on top of the slides . — You go down if you want better holeshot , and up for more speed . — Make the adjustments in 1/4 inch increments though , as it doesnt take much movement to make a difference . — Too low and you kill the top speed / too high it gets hard to turn left — Once you get through break-in you can play to your hearts desire . — Props are always another enigmatic area of tuning , as no 2 of them are the same either . — Just have fun , whatever you do . — Not knowing your driving skills , or previous Basscat driving experience , I will advise that you take it slow in getting it to go as fast as it will , as Kittys tend to walk a little when theyre skinned back and scalding down the lake . — It takes some seat time to get a handle on just how to make her go as fast as she will , which should be around 70 – 75 M.P.H. or so . — Be careful and enjoy . — Hoss
