Re: Which control box?
For a side mount iboats sells a Quicksilver Commander 2000 for a little over $250. I bought one a couple of years ago and love it.....have several over the years on different boats. It is surface mount to the side of the boat and the fast idle lever is easily accessed. Cables will run down the side of your boat. It comes with it's own plug in cable. All you need is to have the right mating connector on the engine end of the electrical cable and Mr. gm280 is looking that up for you. If not, iboats asks what engine it is for when you buy it.
They sell control cables too to operate throttle and shift. I didn't need cables when I bought my box. When you get your box and engine mounted, the cable length needs to be sufficient for the engine to move back and forth side to side and do it in the fully tilted up position also. You need a nice smooth sweep out from the engine and back to the boat so that you don't kink the cables on either end. So the correct cable will be 3 feet more or less in addition to the distance from the center of the transom mount to the center point of the control.
They sell props on here too.
Tell you what. Shop here first and then see if you need anything from your dealer. His overhead seems to be a bit high.
