Diesels?

What? I can't hear you. My ears are still ringing.
I plan, finances permitting, to replace the 6.2 l diseasled RV I had, with a bus chassis with a real drivetrain, so this thread is slightly relevant to my limited interest. I think though, that I have ruled out pretty much everything except the 8.3 Cummins. Anything better than that is way outta my tax bracket, and it appears to be quieter/more efficient/reliable than say the 3208t or the 8.2 detroit or the aforementioned detroit screamer. That 8.3 with an allison 6speed, in a real bus chassis that rides and stops on air, well that'd be just the thing in ye olde service area, or at least on the outskirts of same. What a rig; I've driven slower cars. Oh and to get back on topic, whatever Derek and Robert say on this subject is take-to-the-bank gospel.

You experienced the Detroit 4-71 that made ears bleed.

I can tell when a x-71 is anywhere on the water with in 10 miles from the noise.

That will have been memorable noise!

Morten,

It is important to know that if you are buying modern electronic engines you will be tied to the dealer. Even past the warranty period, only the dealer will be able to provide the software up dates that you need.

I ran an old Allis Chalmers hd5 dozer with a 2-71 for a few days. Even with ear protection it was painful.
I'm a fan of the 6V-92 Detroit. We had them in a few of the Terex dozers for logging. Great sounding machines

While I'm thinking of it, does Robrrt or Derek have anything to aay bout the 3208T Kat in the 250 hp trim? I don't think I care about the no-replaceable-cyl-liners issue as I don't think we can put enough hours on it for that to become an issue. Other than that I haven't heard anything real bad about em and may have found a cannot pass deal on one.

In the Caterpillar world the 3200 engines were looked down on as being cheapo and disposable. They are actually pretty good and very inexpensive. The one thing to remember is that the sleeve meetering injector pump will quickly seize up if there is water in the fuel. I put a reman 3208 into a crane a few years ago and the fully dressed motor cost $5000!

Robert and Derek thanks for chiming in!

Getting a boat is intended as an opportunity to get out on the water and spend some time with my dad who recently tunred 80. I'm looking for something that is going to be mechanically dependable. On the boat forums I've read that there's lost of problems with the Hinos, some of the earlier 8.2L Cummins appearantly had head gasket issues, some of the 5.9L valve issues, etc. All the information seems daunting to sift through from a laymans perspective. I imagine that some of the problems could be related to lack of maintenance, etc so I take everything with a grain of salt. It is the internet afterall!

All that aside, are there certain vintages of Cummins, CATS, Hino's, that I should avoid.

None of the boats seem to have Detroits unless I start looking of older Bertrams or Hattaras.

I've never heard a 4V71 but years ago when I drove motorcoaches I had a 6V71 "Jimmy" behind me. Then later the 8V92 (great engine and lovely sound), followed by the Series 60 12.9L. My favorite with the 8V92 which was connected to a Spicer 6 speed. There wasn't a hill or pass in the Canadian Rockies where it couldn't pull 80KM/h loaded with luggage and passengers. Mind you the AC had to be off due to engine heat and drag.

Prevost Mirage XL with that 8V92, big injectors and the manual were hot rods!

Okay back to boats.

I likely won't be looking at anything that new enough to have electronic engines in it. I think that started in 2006 or 2007?

I did look at an 8.2L Cummins that had over heated, recently had $9K worth of dealer service due to a cracked turbo and manifold. It's a twin diesel boat.

How common is it for one engine to overheat and not the other.

I imagine it got quite hot to crack the turbo and manifold. What other things related to overheating should one be looking for?

Appearantly the engine runs 400 RPM lower than the other one, but I've been "told" that Cummins "say" it's simply a linkage adjustment.

Any opinions?

Electronic marine engines have been around since the late 90s. My favorite Cat engine is the 3306. I had a Cummins 555 and it was also really nice.

Over heating one engine in a twin engined boat is not uncommon. The first thing to look for with overheating problems is that the root cause of the failure has been addressed. This is especially true with boats that have been repowered.

One engine running slower than the other is most likely a throttle problem. It could also be something as stupid as two different spec props. I will say that it can be tricky to compare the performance of two engines in the same boat. Some variation is normal. I have seen people get carried away "trouble shooting" these things. Good instrumentation and careful testing is the key.

What size/class boat are we talking about? Ocean or lake? Long distance or day trip? With more info I could get a better idea of what you want and what you can get.

Hi Robert,

It would be an ocean boat moored at a marina.

Likely something 38' to 47' @ the water line.

Most of what I'm looking at only has a range of 250 NM at cruising speed. I would likely run at displacement speed most of the time so the range would be significantly higher.

If I could afford it, I would buy a Nordhavn 40 with a Lugger engine and a Yanmar wing engine. But I can't so that's that.

I had originally thought of something $200K or less but I'm now at $100K or less.

I have thought a little about whether or not to post anything about the spelling of Cummins, and have a hard time biting my tongue (as some of you know).

I have met 3 of the people who regularly post on this forum and Derek is one of them.

I met him when I was in the market for a built rally car and I drove his Golf. I seem to remember it was high compression ~ 13:1 (I think). The car was an absolute animal.

Derek is a cool guy, a guy who has done a lot in life, and these types of people have a lot to contribute and I for one respect him for that.

Reading through the forums over the years and learning that he barged a house to an Island, lifted it, build a foundation under it, collects rainwater for grey/black water (I think), flies a float plane, set incredible stage times in his Golf, competes in sailboat racing, etc...

I respect him and anyone who even knew a little bit about his character and what he has contributed over the years would never call him out of a the spelling of Cummins.

Let alone post a collage of Cummins logos!

Shakes Head!!!

I hereby resolve to give Derek more shit about his spelling. Since I've known him since we were friggin toddlers I should be able to lay it on real thick. Course he still won't give a happy mouseturd but I need a side hobby.

Particularly from this Taco guy whose total contribution to this forum has been complaints and criticism of people who do try and help people..
Crap that is completely without value, humor, or is in any way enlightening.

If you're under a 100k the Lehman will be one of the more obvious and plentiful engines. The small 4 cyl Cummins had a lot of problems I think, maybe injectors coming apart or the whole motor? Bayliner mounted a bunch of Cummins in the 34s I think that suffered water intrusion and blew up regularly . The Hino has been pretty good, replacement parts are eadily available and there are a lot around. Lots of info to be had at http://www.baylinerownersclub.org/forum/forumdisplay.php?8-MotorYachts . There is a guy named Earl that travels the US in a motorhome that is legendary with Hinos . He lines jobs up coast to coast and everyone seems amazed at his expertise and really loves the guy. From rebuilds to minor tune-ups he is the guy. The admin of the forum is a friend of ours so if you were interested and got held up in the registration process I could make a call. Also this forum http://www.iboatnw.com/forum/forum.php is mostly local PNW guys and lots of good info. I was one of the original founders there many years ago.

I've only owned one diesel boat and it had BMW turbo 5 cyls. NOT the engine of choice btw... all the rest were gas. A twin 350 cid gasser at 20,000 lbs sucks a lot of fuel btw.
