Anybody have a 20" lower unit that would fit my 82 115 hp inline six? Currently fitted with a 25" (bought it that way) but the boat needs a 20".<br />Or can I just buy a shorter driveshaft and remove the "spacer"? Someone said I could shorten the shaft but as it is splined, I don't see how. And what about the shift shaft/linkage?<br />Thanks again, Rich
