Hi Hoffontour
Your engine bears a lot of similarities to the old Perkins P3 tractor engines but I couldn’t find a
photo with all the features on yours. I’m guessing that the valve cover has a decompression mechanism in it hence the unusual shape. A lot of the P3 range had an in-line
injector pump and the rest had the DPA CAV
pump like yours.
Does your
boat have
keel cooling or is there a
remote heat exchanger tucked away out of frame?
