View Full Version : Dimensions of PCM 351 VS PCM 302

"I have an 86 Shamrock with a PCM 302. Needs new tin, circ pp,carb, intake manifold so the rebuild option is pretty costly. I am told that a PCM 351 is 1.5 inches taller and 1.5 inches wider. Since my manifolds are above the deck in this center console boat, I think it will fit fine. I hear talk, though, that the oil pan is deeper and the base angle is slightly different leading me to believe that the "bottom" of the motor may not fit in the bilge or that it may not line up to my velvet drive. Other people say that the bottom of the motor is identical and that the only differences are at the top of the motor. Can anyone help! Thanks SO MUCH!"
