I'm trying to find out if anyone out there has experience with the 24ft. Chaparral Villain III. I just purchased one a couple of weeks ago. The boat is solid red with 454 MAG/Bravo I and has very low hours. My only complaint is the ride quality. The boat handles rough water fairly well (22 degree deadrise hull), but porpoises at any speed and nearly any trim angle. This porpoising appears to be directly related to the weight at the back of the boat. The more people or gear we have near the back, the worse the ride gets. The boat is running a 23-pitch Mirage (not Mirage Plus) right now. I just contacted Hydromotive today and they recommended their Quad 4 to provide stern lift to correct my problem. I went ahead and shelled out $550 for a new prop. Does anyone have experience with this prop on this boat or with trim tabs on this boat? Mine doesn't have tabs.
