I was on a boat for 5 years that had the Perkins. My own boat, I tossed a Volvo and replaced it with the 3GM Yanmar. Kubota is a good engine also. Leanne s/v Fundy |

I have lived with the 4-108 for about ten years (twenty years ago) and
took the Yanmar's big brother, a 4JH, around the world in our Swan 57, Swee****er. I'd pick the Yanmar in a second. Among other things, a 3 cylinder has inherently less vibration than a 4. (In a three, the pistons are 120 degrees apart, while in a four, they are 90 degrees apart, so that when one hits top dead center, its mate is at bottom dead center.)

The only hit that I know of about the 4-108 is that the operator's manual introduction for bleeding the fuel system starts out with "For the operator who is unfortunate enough to run out of fuel," and ends up with "If this doesn't work, call for professional help...You do have a working radio and did remember to pack some flares, didn't you?" It's a real dog to bleed. Not being personally familiar with the other choices, all I can say is I've had a 4-108 for the last 5 years and it's been bulletproof. It's never taken me more then 15 minutes to bleed mine, and that was the first time I did it. Now that I have it down to more of a "science" and can do it in under 10 minutes. And now that I've installed an electric pump on it, I can bleed it in around 5 minutes. Steve |

1900 running hours suggestds that overhaul time is due soon, maybe very soon.... Funny, my Perkins 4 cyl diesel has over 2500 hours on it and runs perfectly. It was made back in 1965 (no, I don't use it much). Right, I forgot - it's in my tractor. Seems an engine changes when it's in a boat. Or perhaps it's the lack of maintenance. Any well maintained diesel fed clean air & fuel, run under proper load, should last pretty much forever. 2000 hours is nothing. Peter Wiley |

It's had new crankshaft oil seals at both ends at 3,500 hours, 100 hour oil changes all its life. It's starting to rattle a little, but still gives good power shoving 10 tons along at 6kts with 2,500 rpm. It runs in a cramped, hot little engine room with poor ventilation, and above 3,000 rpm (rated at 4,000 max, 3,500 for commercial use) rattles rather louder. Tappets are OK, so I think the little ends are beginning to die. So they don't run for ever, but 5,000 hours plus in an ill ventilated cupboard isn't too bad. -- Jim B, Yacht RAPAZ, Summers in the Med, winters in UK jim[dot]baerselman[at]ntlworld[dot]com |

I installed a new Yanmar 3JH3E two years ago and just got back from a 5000
mile, one year trip to the Bahamas and back to Salem MA. We motored almost all the way, down the ICW and back, early 1000 hours. Boat is an 1968 Apache 37 at 15000#. Prop is 17 X 12 three blade sailor. The engine was great. Other than things I did to try and mess it up (flooded four times due to faulty exhaust, fuel in the crankase due to incorrect fuel line tightening) it performed flawlessly and tolerated my abuse. Quiet and smooth enough, great mileage, nothing broke. Parts available everywhere. Check the web page for details on the trip.

I am not a mechanic, but I thought one of the reasons one would go with a diesel is for its reliability. If I had a piece of equipment that operated 8 hrs a day, 1900 hours would be about 237 days of operation . Most of the machinery ( diesel powered ) at my work operates 24 hrs a day. The equipment does get a service ( oil and filter change) every 250 hrs of operation. What a huge liability if they had to overhaul every 1900 hours. |
