Subject: 4107 / 4108 fuel consumption

Anyone know what the gallons-per-hour fuel consumption per rpms is for our Perkins in 31/32s? Am planning a cruise down the coast for next month and the likelyhood of having to motor for extended periods is high.

Even a rule of thumb would be helpful.

Less than a gallon per hour

I average about 1/2 gal per hour motor sailing

use a 1 GPH rule and play it safe. Carpe Diem had a 4107, was a bit overpropped and used about that.

If you have a noticable smell of diesel inside the boat/engine compartment and a noticeable high rate of fuel consumption, you should check all of your fuel lines. You may have a leak. See if you have diesel in the bilge or the drop pan. Check first the lines feeding each of the injectors as these are the ones that we loosen to bleed the 4-108 and are most often the cause. I place a paper towel under each and run the engine to see if there is leakage. After that, check your diesel fuel return line and the fuel filter(s) lines, fittings, and seals.
