Well, I definitely need at least one belt for a hydraulic pump to run the anchor winch. And sure - at some point it might be nice to have an engine-driven water pump as well. Could use for washdown, emergency bilge pump, etc. But the problem is that the four-row pulley extends several inches past where the bulkhead would land. Moving the bulkhead forward won't work for any number of reasons (I want to maximize cabin space, the current bulkhead is positioned to be the forward face of the pilothouse and it ties to a major cabin support beam) so I'm stuck with what I have. The motor is really wedged in. About an inch of clearance aft and above and maybe that much forward after I swap the pulley. The companionway steps clear the thermostat by about half an inch on that side. As it is I might need to mount a jackshaft for the anchor winch pump since I need to move that as well. It was originally mounted in front of the motor (on the platform welded to the starboard engine stringer) but that placement would interfere with my new bulkhead too.
