I owned an '88 24' with a 454-365hp bravo. Fun little boat. That was the biggest boat they ever built (except for a one off 32') They went out of business around 94 or so. The 24' was a really fun boat however the fit and finish left a lot to be desired. It ran 68-69 mph with that setup. The boat handled fine as long as you were going in a straight line. In the turns the boat liked to slide pretty drastically then all of a sudden it would catch and outside chine and want to roll up to the out side. I put on way over a thousand ours on my boat and I would drive the hell out of it. The hull held up great. Alot of the hardware however had to have constant attention as they didn't thru bolt anything. they also don't like the rough water. Because of its bottom design if you got in anything more than a 1-2 chop it would just beat you to death. A really fun lake/river boat however.
I still have a real soft spot for the 24' Switzer.
