Not sure what engine you have. Mine is Westerbeke, and the oil filter was relocated to the bulkhead above the engine. Access is easy, so changing is easy (unlike the impeller!). Only thing I would say is ensure the mounting is solid. Sometimes a lot of force is required to unscrew the old filter - not sure why, I change it annually. So consider the rotational force as you mount it. IMHO a worthwhile upgrade. Good luck!
