What better name for my Perkins 4.108, 50 hp diesel engine than Danny Diesel. After all, he was on my mind when I woke up this morning. I had a visual picture of his expression 48 years ago when he became aware that I failed to respond to the oil indicator light in his Ford Pinto. He wasn’t happy having recently rebuilt that engine. A month later, I fried it.
Fast forward to the present. when my CSY 33 mentor, Dag Hansson, took the time to give me a tour of the 40 year old engine perched below the galley sinks in my sailboat. I listened, took notes and asked questions. Later that day in the quiet solitude of the setting sun I rewrote my notes. Below are things to know about Danny Diesel and perhaps about your prized engine too!
Check the zinc on the starboard side of the cooling engine. It is under the six sided bolt head.
Heat Exchanger – blue cylinder along back of the engine – look for a zinc – should be a spare heat exchanger on the boat-if so take it to a radiator shop to have it acid washed, then pretty it up by repainting with blue Chrysler paint
Oil Filter – orange cylinder in rear s/b side – change every 100 hours: unscrew to loosen, place a freezer thick zip loc baggy around filter, catch filter and oil drippings in zip loc, dispose of properly
Secondary Fuel Filter – blue cylinder with a white label on it; above cooling engine and below to rear of air filter, 2 micron filter
Lift/fuel pump – manually lift and lower when engine is bled to get air out; it is the small tab with a hole in it; pointing to it with a pencil in pix below
Electric Fuel Pump – on circuit breaker labeled ‘fuel pump’
Battery Switch – behind circuit board
Impeller is the salt water pump
Salt water hose lies across front side of engine leading into impeller
Coolant is collected in the bottle on bottom of engine room- need to clean it out; check inside the coolant thingy to see if/when to add more
Pressure Cap for coolant is same as in a car; get new cap at NAPA Auto Parts
Silver tape – get some for inside engine doors
Injectors – have mechanic do every 400 hours
Valves – have mechanic do every 1000 hours
Hope this helps
