I'm looking at putting together a simple basic outboard water ski boat and perhaps a water ready package. So I'm wondering about a few things. My first Hydrodyne a 17.6 XB had dual cable steering with the 150 Evinrude Motor. Is hydraulic steering really needed or should it be an option? What size of motor is really needed? A 90 will pull a bare footer on a 17.6 Open Bow Dyna-Ski. A 115 will pull two bare footers on a 17.6 Open Bow. A 130 gives a little higher top speed and a 150 will pull lots of folks and make it into the low to mid 50's with a water ski prop. How many gauges do you need? Tach, trim, fuel, pitot tube speedometer . . . . what else do you really need? GPS Speedometer? Is a plain two color interior good enough? No swim platforms, one swim platform or two? Trailers . . . . I like the custom Eagle Trailer with side guides and a bow stop but I can put a boat on a nice Yacht Club for less money. Eagle and Yacht Club are made by the same company. Do you want a windshield? They cost the same for a 20' or a 17.6. Should it be an option? I cannot build the old 18' style of boat for much less than a 17.6. There is about the same material in both boats. Offering a windshield could be very expensive. The Coast Guard horsepower guidelines and floatation requirements would not allow the same size motors now as folks have put on them in the past. The insurance industry is also a factor. So give me some realistic guidelines and I'll develop a product for the entry level or budget buyers.
