That is crappy. Carolina Skiff and the service department kept the company I worked for in the late 80's ALIVE. They were not too bad to porpoise as I recall. (Original design) My dad's newer designed 14J 20hp Merc will definitely porpoise if there is noone in the front seat. I can move the fuel tank foreward enough and put the cooler up there and it almost removes the ill effect of having a big *** guy sitting at the transom... No mas driving with the tiller anymore. Give me a steering wheel and a throttle I can set and cruise. That tiller of my dad's will wear you out on a long cruise.
To get a clear picture of what your fighting, Are You talking neutral trim or fully tucked and porposing?

Fully tucked, and porpoising. And engine height isn't the problem as I can change that at the flick of a switch. The 3blade yamaha semi cleaver aluminum that came on it was undriveable in my opinion. The 4 blade solas made theboat controllable, but still bounces. I know on CS board, the 198 is a known porpoiser, but the narrow beam isn't. The modified V's seem to be the worst. I've had several flatbottom boats now thatneeded a fin to stop them from porpoising. I'm going to try and prop this one to fix it, if not it will get a fin to.

19 ft "v"series for mine, 65 inch narrow beam. Fully trimmed down. Controllable below 4000 rpms. Fuel tank moved forward under custom glass over 3/4 ply console. Sorry to hijack Phat.

Ditto on the highjack! Glad someone got to go fishing. The weather has been tore up,:nut: for Florida I mean....
