I had posted in 2020 about options for my good old Perkins which had been slowly getting worn out....and we are now almost done with the rebuild. We pulled her out in December and have since taken everything apart and broken it down. Fortunately there were no major surprises or stumbling blocks. Chris Oliver of Portside Marine in Annapolis and I have replaced the pistons, rings and re-connected the rods to the crankshaft; the reworked valve assembly and injectors are awaiting reinstallation. We will be replacing the old notorious, rear seal "rope" with a fancy and exorbitantly overpriced gasket (supposedly new and upgraded and looks like nothing more than shaft stuffing), changing the v-belt to a serpentine belt and will be replacing the unwieldy "P.I.T.A" secondary double-clamp style fuel filter with a new spin-on cartridge which required replacing the oil cooler to make room for the conversion kit. We hope to complete the rebuild and shop test her in the next two weeks and reinstall into Non Sea Quitter by mid-March. We'll be running the new ignition and fuel-cutoff stop switch from the bridge deck closer to the helm. The only rather irritating thing about the engine remains the nearly impossible to-get-to 3/8 bleedscrew on the governor/injector pump assembly. (I hope I described that properly) ....I will have some photos to share in March if anyone is interested....Portside happens to have another 4.108 in the shop! Want to buy it? Cannibalize it???
