I found a motor I want for my boat but it is a long shaft and my boat is set up for a short shaft. I talked to the man at the marina and he told me it will be just fine putting a long shaft engine on a short transom. Is that true? It is a 75 evinrude 40hp with electric start, but it can be converted to a short shaft. If I did that where would be the cheapest place to get a short drive shaft, water tube, and shift lever?
