1987 lund baron 2100v 3.7 liter 180 alpha one gen one outdrive. so i had all kinds of problems getting this boat going and decided to rebuild. for the interim i bought a 87 wellcraft bowrider with the same engine outdrive to swap into my lund while i rebuild. well the engine in it is a 3.7 165. the engine in the wellcraft shows 234. something on the hour meter! i can put my 4 barrel intake and carb on this motor right? is that the only difference between the 165 and 180?
