I have a 1992 335. My diesel cabin heater is located underneath an access panel at the bottom of the very deep starboard aft cockpit locker. It's location makes is nearly impossible to service and the air intake to the heater itself has got to be limited at best, creating combustion problems, etc. Does anyone with a 335 have ideas for alternate locations for the heater? Thanks for your help. Gary Wyngarden S/V Shibumi
