Any views on the above engines?Are they good.Heard they have released new models till 750hp (6135SFM75). Are they common in the USA?

Frank,any opinions??

I can't speak for that particular engine. But as a rule the Deere's run very well and very long. Every engine is going to have it's own particular issue of sort's. Commercial guy's use them with very good success around here, lot's of hour's. The only problem with JD engines is that the marine market is such a small piece of the pie for them. Around here support isn't great. That being said they (as a whole) have a great product in my opinion. I wouldn't hesitate to put a Deere in my boat, can't say that about some other brands. I think I would if possible get a hold of your Deere rep in your area and ask him for some names of folks that have already purchased the engine you are looking at. I would ask for commercial guy's particulary, as they put way more hours on their gear than rec guy's. If they don't like them they'll tell you. As a rule most folks are eager to share how they feel. One important question would be to ask "how many hour's" do you have on them. Hope that helps, Frank

If you post this in the New England forum, I think you would get some good (responses) feedback.

Hey Faizal,

Your not thinking fo straying from Scania are you?

If you've decided to look at other manufacturers you may want to check out Volvo. They've increased their HP range to 900 HP with using an IPS system.

That would save a lot of expense in running gear and provide an efficient package.

What it would feel like running aground somewhere in Eastern NC with an IPS powered rig. That's gotta hurt!!!
Nabeelah, go with information that doesn't come from the "company". They all say they're fuel efficient, powerful, quiet, durable, etc............ Go to the horse's mouth, talk to an owner. Frank

If they are as tough as their farm and industrial engines I'd take one in a heart beat. Some of the most reliable engines I have every seen. May not be a strong as a Cummins or Cat but I have seen them run alot longer under the same conditions.

Friend of mine's dad owns a fish house here and installed new gen sets in 3 of his trawlers 1 JD and 2 Cummins, all three have 6000hrs. plus and both cummins have been into numerous times. The JD is still chugging along, never been touched other then service.

Hi Mike,
No its for a friend that I am gathering info for.I am loyal to the Scania brand!!

Thanks Frank-Scanias still lead the pack in the commercial Cray fishing industry in NZ.A very good testimony-high torque,very slow reving engines and reasonably priced with very good back up in the Sth Pacific.These engines are the forefront in European patrol crafts and last for ages!Am not an expert- but I do love slow reving engines as lesser wear and tear,less noise etc.

Frank-I am not an expert,but what intrigued me to dig deeper from Scania was the modular concept- parts are interchangable whether inline or vee configuration.Parts are readily available as any of the engine spares can fit each other.Also one cylinder one head concept.Not thirsty as Cats though!! Am still a Cat fan !!
