[Fr. Frank]

I saw a 23 CC with an inboard tunnel like that over 20 years ago. The boat was an '81 and had a 160 hp. Lehman diesel inboard under the console, which the owner claimed was factory installed on a special order.
It was a pig for performance. Slow to plane, and a top speed of about 28 mph. On the other hand, at something like 2300 rpms and 25 miles per hour, he claimed it only burned 3 to 3 1/2 gph. [img]/images/graemlins/confused.gif[/img]
It had Bennett trim tabs that were each about 1/3 the width of the hull, or about 3 ft wide by about 10 inches deep. Huge fuel capacity, too. I'm not sure, but I think it was like 170 gallons. There was no below-deck livewell.
We had it in dry-storage at the marina where I worked. We were SeaCraft dealers.
