I just had my mechanic put in new raw water pumps on my 6CTAs. The port one is really tough. Formula put a small access hatch from the aft cabin but it was tiny. I cut the bulkhead open for a much larger hatch and the mechanic was able to get to the pump and change it. I went with a new Seaboard Marine SMX pump to replace the OEM Sherwood crappy pump.
