Location: davis,IL | I did the same change a few years back. Went from a 12v, 50# to a 24v, 74 #.... the 12v had a 42" shaft... the 24v a 54" shaft. From personal experience I can tell you this... the 42" was too short...just enough in calmer waters... 18 to 20" chop and it would surface the prop. The 54" (Maxxum 74) is currently set at its lowest point without making a problem in its stored position ( i can still drop it about 10 - 12 "). From the standpoint of of 12 to 24 volts....incredible.... I'm not a big fan of running my bowmount (spooks fish)... but I can say that my 12v would last a day at best on the water. My 24v, I can go a couple of days between charges. For shaft lenth.... the 42" covered most situations o.k. but had its limitations. The 54" has been all I could ask for.... the only time I have to worry about the prop surfacing is in 3' + waves. The downside is the prop is a solid foot below the surface (6" below the keel) in calmer water and the head is still sticking up close to a foot on the bow of the boat. This is not a real issue when casting to the sides of the boat but does get in the way casting straight off the bow. For wiring... at the time when I did the change... somebody had a sale on 12', 6 guage jumper cables, I cut off the big clamps, soldered on the correct terminals and had my motor wiring...... Remember..... for this heavier is always better.
