Anyone know what type of quality Navistar engines are? I thought they were mainly for trucks, didnt even know they had a marine engine.


comparing them to yanmars or cummins how are they performance to value ect?
 
I think they are International.

If I remember it was a name change or a merger a while back.
 
I had an F-250 Ford pickup with a Navistar engine. It was fine and is a common rail engine like the newer Cummins QSB, QSC, and QSM engines. Yanmar has a computer interface, but their engines are mechanical fuel systems; not all bad, but not modern.:)
 
There are marinized john deers, international. isuzu, etc etc.
 
would you fine gents trust them in your own vessels?
 
I know nothing about those engines, good or bad. My question would be where do I get it serviced and how hard are parts to get.
 
Why not if parts are available. The marinization is the question. Pumps, heat exchangers and other non standard parts may get hard to find.

If I were doing a repower I would look for support for the engines years down the road when I sell her. if they are unsupported or hard to find parts for you will get less for the boat.
 
Generally speaking I'm against being a trailblazer when it comes to re-powers. You want something that's a known quantity, that you'll be able to service, trust, and sell at some point. One-offs are a put off.
 
Navistar has made a lot of different engines. Can you give us a hint about which ones we're discussing here?
 
7.3L Powerjokes... decent engines in trucks. Can't speak to the marinization or Starpower. Fully electronic though. I'm usually leery of electronics in a marine environment.
 
I remember it on YW a while back but never really looked into it. I know a friend that had the 2005 powerstroke had to put in $4k of injectors at 130K miles.
 
7.3 light duty International truck engine. Very much like the ford 7.3 but with heavy castings for accessaries. The engine in a light duty truck (I had two of them) was a considered a 300-400k engine and then you threw it away. The 3208 Cat engine really falls into the same catagory, it was built as a light duty Ford truck engine. Light duty meaning under 26,000 lb gvw or in some cases maybe a little more. Both engines are dry sleave engines. Interesting point both engines have been replaced with in line six's in the case of International the 466 wet sleave and the Cat C7. I don't think International did any marine conversions. Somebody else marinized them. They are probably fine engines if the conversion is well done. The 330b/370b Cummins started life as a water pump engine before they put them in Dodge trucks and fall into the same class of engine. Have I stepped on enough toes?

That was a different engine. The 6.0L your friend had was suitable only for mooring purposes, however, the injectors in this 7.3L ain't cheap either. Figure about $275.00 each.

scary... None of those engines are "dry-sleeved" they have no sleeves at all.

Why does everybody refer to parent-bore engines as "throwaways"? When they wear out you rebuild them like any other engine the only difference is they have to come out of the vehicle to be rebored. Nobody just throws them away unless they've got a lot of spare cash. Also, the 466 was not a replacement for the 7.3L they ran in concurrent production. The 6.0L V-8 replaced the 7.3L. Now we're talking about a throwaway... as in; throw away the entire vehicle.

Hell that 6.0 moved me to buy the Dodge. Trucks OK but the Cummins is SWEEEEEEEEET.

I know of the 7's that ran forever or at least 500K miles in the trucks but as a marine engine it was not popular and leave the question of parts availability for the marinized portion.

What do you want to know since I know that one well also ;)

Who did the total refit on it? I see hes a local guy but didnt know there were any shops around that did that quality work without charging 200k lol


Alot to think about with the engines seems like they may have taken the marine parts from mercruiser since that what the engine description kind of insinuates.

There is a beat up 36 listed for 9 grand with running Cats in it maybe i should try to pick it up for 5k and gut it lol
 
A guy I know has a perfect quote for this thread:

"The money is in the iron."
 
I THINK (but I am not certain) that these were marinized by someone other than IH, so I don't know how easy it will be to get the kinds of parts mentioned above- pumps, heat exchangers, etc etc- all the stuff that needs to be replaced sooner or later. I am not aware that IH marinizes their own engines- I don't know who does it. IH has built a lot of diesels, so the basic engine assembly is more than likely just fine, but the peripherals may drive you nuts if you can't get parts for them.

Any V8 diesel in a 36C is a tight fit. From a maintenance standpoint, the outer bank of cylinders is particularly hard to get to. Much easier to maintain in-line sixes, plus they are a bit smoother.

Your right they're not sleeved and they did use both the 466 and 7.3 at the same time. I had some of each at the same time including the cat, and I even paid the $10,000 to rebuild one of 7.3' but I was lucky my heads were reusable on that engine. The 7.3 is no longer offered and is replaced by the much superior 466. Rebuild life was considered about half of new and it just not cost effective to do an in-frame, that's why we call them throw away engines. You can rebuild almost anything but these aren't like wet sleeve engines that will run as new over and over again.
