What Brand Of Diesel Power

I see Cummins more in the 35/50' yachts. I little more info will probably get you good advice here. Are you talking a SF, FBMY, Express, trawler etc.? What kind of speeds are you looking for? Do you plan extended cruising or day trips?
BTW, welcome to YF Netgain1

I would go with the CAT's. They're easy to maintain, maintanence parts are cheap, service is worldwide, no issues with getting things covered under warranty, they have a lot of torque.

I've had issues with several late-model MTU's lately and getting things covered under warranty always feels like pulling teeth with them. I've had aftercoolers leak on 2 series 60's 2006, a freshwater pump go on a 2007 16v2000 and a fuel pump/injector..........

I'd go with the Cats. All diesel engines are tough, heavy duty motors, but Caterpillar is what you want. The reliability and service network is 100%. I run a boat with 3412s (C-30s) and have only had to perform the routine maintenance required. Seems like MTU just has too many parts to break. Cummins is more of a small-medium boat engine builder.

Another vote for the Cat's,
Have cats now and in the last boat with no problems.

the other thing is they can be worked on just about every where you go. as cats are used world wide.

Happy boating

Ditto on the CATs.

Hi,

I would have to agree that CATS are the best all round power plant these days.

I have MTU's and they are due for service. Very expensive to have serviced. Go with Cats

Hi,

While the start price for CAT's might be higher ( This is the first time I have read this) you will save the difference in operational expenses/frustration and downtime quicker then you realise.

Hi,

You will not get any better or quicker answers by posting the same questions in multiple places on the forum.

Your original thread on this subject is here:http://www.yachtforums.com/forums/104110-post9.html

Engine

In case you already know where you will sail with your new Yacht I would suggest to check the Engine manufactures Service Dealer locations in this area.
The one with the biggest network should be your choice. Isn't it easy ?

For MTU you have also to check Detroit Diesel services in case they work together and do not forget MAN Marine Engines.

Hi,

I think in post No 1 the OP stated clearly enough where he intends to cruise.

cat 32 acerts

I've been using cat 32 acerts at 1825 hp for the last 3 years and have no isssues with them. in my opinion if you compare same spec engines with MTU CAT should not be any more expensive. Are you comparing similar spec engines from both manufacturers?

Does anyone have the actual required maintenance costs for MTU / CAT. I have heard that the MTU scheduled service expense is very costly.

Is it possible to merge this thread with This thread where the OP asks the same question in two diff. threads.

The threads have been merged.
