It's a bit late in the season, but now is the best time to buy! I just picked up a 16 foot I/O Cobia tri-hull open bow with a 4 popper chevy motor. Someone told me it was the same as the vega motors? It's a Mercruiser 120. It's pretty quick, tows a tube or the knee board at about 40mph! But once you get 4 people in the boat it gets sluggish. I am looking for some decent boat forums and some info on the motor, like what is the car or truck equivilent? It has the intake and exhaust on the same side and the timing cover is offset from center to the other side. Someone mentioned that it is an iron duke. I can get pictures this weekend. Man, having a boat sure makes it hard to get to work!
