The I/O bass boats aren't that desireable. They tried to make it in the market, but people just didn't buy into them. First and foremost is the issue with cold weather operation of an I/O versus an O/B. If a serious fisherman wants to go out and fish in December, the I/O winterization is a real killjoy. Most bass boats also don't weigh enough to warrant the power advantages of the I/O setup. Lastly, the shallow draft of the bass boat means the I/O sits up high and you lack the ability to get the outdrive out of the water when running in the shallow stuff. It also intrudes on the deck space when the engine is in the boat. Lots of reasons they didn't take off in the bass boat market, but I sure didn't know they ever made a Ranger with a Bravo outdrive.
