L120s are venerable proven economical large capacity naturally aspirated understressed old engines, operating at modest rpm. Parts are readily available from American Diesel and others. I think they are a safe choice.And I don`t think you change the injector pump oil every 50 hours, that`s wrong.
I`ve not owned Volvos but many are turbo, I think they operate at higher rpm, some members complained about parts availability, a friend certainly complained about that, and cost, turns out his engine is a Perkins rebranded as Volvo, with Volvo marinizing. Hopefully experienced Volvo owners/aficionados will post to help you.

Neglect can be as detrimental to an engine as improper use and care. However, these Jurassic-era diesels can probably stand neglect better than some of the higher-strung, electronic, later-generation engines, I don't know.

Based on my long-ago experience with Volvo Penta engines, I would venture to say they are much better engines than the old Ford of England Dorset diesel (base engine for the FL120). However from what I read from time to time on this forum, parts and support can be very difficult--- to say nothing of expensive--- to obtain on older Volvos, at least in some parts of the world.

Having lived with a pair of very good (so far) FL120s for the last 17 years I would be inclined to go with those engines IF...... they surveyed out well and an oil analysis gave decent results.

Oil analyses are useful primarily as trend indicators. A one-time analysis won't indicate any sort of trend but it can give some clues about the internal health of the engine so it's worth doing if you or a competent engine surveyor knows how to interpret the results.

Don't know anything about the vessel type you're looking at so I have no clue if it does better with 120 hp engines or 156 hp engines. My own opinion is that in boats and planes there is no such thing as too much power unless the Sea Ranger is a displacement boat, in which case there is.

But a greater amount of iffy power may not be as smart a purchase as a lesser amount of reliable power.

No, that's correct as spelled out in the Ford and Lehman manuals (we have both). The reason has been discussed here in the past so is in the archives, but the 50 hour oil change injector pump oil on the FL120 is a very important service requirement, and it gets even more important as the number of hours on the pump increases and/or the lubricity of the fuel diminishes.

The FL135, which is a different engine (Ford Dover vs the older Ford Dorset) is a sort of "new, improved" version of the Dorset (FL120). By the time this engine came out Ford of England had figured out how to lube the injection pump using the engine's own lube oil. So even though the increasing oil dilution leak-down issue still exists (it's the nature of the beast on these prehistoric, in-line, jerk-injection pumps) the fuel leaking down past the plungers is diluting three gallons of oil, not half a quart. So the FL135 does not have the 50-hour injection pump oil change interval requirement.

The good news is that changing the injection pump oil on an FL120 is a quick and easy process. We've done it in mid-cruise before (not with the engines running, of course), and it's no big deal.

My only larger boat experience is with my Volvos and still working out kinks

See if the seller(s) will allow you to take an oil sample. Take it to your local fleet/heavy equipment shop and have them send it to their lab (here in Raleigh, NC I use the local CAT dealer, Gregory Poole, they have an onsite lab and for $14 they will have it done in one day).

And your engine choice also should reflect how you are gonna use the boat. If you are gonna run hard and up on plane, I think the 3208 is the best engine of the bunch. Chug along slowly, then the Lehman. But a 3208NA is an excellent engine for that as well. Perkins I believe to be equal to the Lehman for chugging but they have a tendency to leak oil more so than the Lehman. The only place I have seen a Hino is in Bayliner....and in trucks in Japan. Volvo would be at the bottom of that list for me. I think Volvo makes a perfectly fine engine. Just their support is questionable.

Hi, I am making an offer on a 1987 42'Nova Sundeck Trawler with twin deisel Volvo engines. I fell in love with the looks of this boat, but am pretty new to all this, so would love your experienced advice on what I'm getting myself into with this engine?
Will be getting a survey, etc this weekend
Thanks!

Its too bad they are not more popular near you., I have had Perkins, Lehmanns, Cummins,Cat,and Navistar diesels but I prefer the Hino to them for a variety of reasons.
Just an all around good engine.

As I look out my window now in Long Island NY we are getting a food delivery by a Hino powered reefer truck. Across the street you can often see two Hino powered flatbeds that are the most used by a towing outfit that operates there. Across the street in the other direction the Deli and Liquor stores often get deliveries by trucks powered by Hino's. Fairly common and well regarded on trucking sites where they discuss mid sized straight trucks or every kind.

Don't worry too much about it. Parts, while expensive, are not hard to find if you know where to look. Volvo is still making parts for all (or most of) their engines. Like any engine, you just need to do your homework before you buy. PM me and I can tell you where to look and give you some more info.

It was just an observation. I wasn't ragging on the engines. Quite the contrary. They just aren't that popular over here. They are VERY popular in Japan. I think they are related to Toyota in some way???

Hino makes a good engine, no doubt. But the marinized ones used a bunch of aluminum in manifolds, etc and had corrosion issues. And it may be hard to find the parts at this point. But that is not Hino's fault.

MBMC- What specific Volvos are you looking at?

I imagine they made more than just one model of engine that year. Do you know the model? Maybe the horsepower rating at least?

Hino is a subsidiary of Toyota. Hino branded trucks sell in Australia. The Hino engine was commonly fitted in Bayliners, the 4588 owners on my marina seem happy with them.
