Rock,

I ran a Db w/ honda for years in lower river and tidewater. Fine for limited applications. Some thing to consider:

1. Most driftboats will only go so fast, no matter how big the motor, approx 8-10 mph. One run in my favorite bay would take about 35 minutes in the db w/honda, now takes about 7 minutes in the sled.

2. even with a "dolphin" the stern will dig down and bow up, so you need deeper water.

3. You can go up riffles if they are about 1.5 - 2 ft. Passangers and fish must go as far up front as possible, hanging over bow, and your prop will grind in the rocks. My honda props were good for about 2 years, with me hammering on them a couple of times. Rocks just beat the sh#t out of them and they keep getting smaller.

So there are you limitations for a std DB, Clackacraft makes a hull called the magna-drifer or used to, but it had the same basic limittions only with a slight improvement.
