Which is better? Cat or Cummins

Although I am sure Cummins are great engines, If I had the choice, I'd get Cats ... just a personal preference ...
 
MAN oh MAN

I have only had my MAN's for a couple months, but so far I am happy went through a very good tour (read:education) with the local MAN mechanic and learned a lot. I will say this, they sure do FLY... :thumbsup:

I had CAT's before and had little to no problems with them either...

I guess what I really have is a good mechanic! :wink:

I have heard that the MAN major service intervals can be really expensive. I guess we will see as more time passes.

Depending on Size

Yanmar's new big diesel line up is pretty impressive for boats under 42 feet. Yanmar's "take a lick'n and keep on tick'n" rep is soild with me. I had two small Yanmars which ran like perfectly for nine years for me. I think the Yanmar guys know how to engineer the "hard knock" maintenance out of their products.

I'm new to the Cummins life, but I'd have to say their product is a quality engine with no more flukes than other big block diesels. Their 6C line in mechanical engines are pretty advanced in many ways, except the raw water side of their product, which seems to have been designed by everyone else but Cummins which is something like wanting to design a race car by committee and a camel comes out of the factory.

I am disgusted with the Cummins marine dealer network prices. I think they have absolutely lost their minds on part cost and labor rates.
 
Yanmar has a great line up to 900hp. But so does everyone else.

If I were in the market for up to 600hp. I'd have to go with the Volvo and IPS. I know parts will be expensive, but the magic of IPS is worth
the extra cost amortized over 10-15 years of ownership.
When I get the 340 repowered it'll be Yanmar all the way.
