Scania Diesels

The Swedish companies Volvo and Scania are two of the largest manufacturers of heavy trucks in Europe. Both are also making marine diesels and Scania mainly for commercial vessels. They have a good reputation in Sweden, where they have been produced for over a century now. About spare parts in the US, I guess you will have no problems even if it may take a couple of days to get them.

Yep, here in the Channel Islands we look after a number of Scania motors on the fast ferries and fishing boats. Not much goes wrong as they tend to be slow/medium speed marinised truck engines. Tough stuff.

Scania engines

I see this is an older post, but I thought I would reply since Scania's are rare in the US. Very common in Europe. I have owned a 50' Uniflite Motoryacht since 2006 that was re-powered with Scania Diesels in 2002. Same engines as listed above(675 turbo's). The are fantastic engines and are very quiet as the are four stroke. We have had virtually no issues with these engines. Easy to work on and reliable.

Couldn't agree with you more. I just ran some sea trials on a commercial boat with Scania 700's in it and it was fantastic. No smoke, lots of power, and very little vibration / noise.

Scania's are very good and durable engines. I've heard getting parts in a timely in the US can be pretty difficult for them.

Scania engines

Scania commercial marine engines and the commercial offrad engines are well known for their reliability. They are long lasting and great quality. We see them a lot in Europe in commercial inland vessels, both cargo and passenger. The Scania trucks, especially the variants with the turbo compount engines are well liked by our drivers because of their acceleration and uphill performance.

After Volkswagen took over Scania and MAN, both companies were improving even further as far as quaility, performance and service are concerned, because technology and knowhow are transfered between them.

Like on of our engineers said :"I like those red engines." But the best engine of the world is only as good as its service. If your business comes to halt because of missing parts or service, even the best engine does not help, if she does not run. From what we hear, outside Europe there is still some room for improvement in the service field.

you see these engines occasionally in Down East commercial boats
