Vote: best brand of inboard propulsion engine...

[B33RND]

I mean with BEST, just what would be YOUR PERSONAL CHOICE, taken your personal considerations into account.

I am anyway searching for a reliable and economical engine for medium heavy duties (complying to prevailing emission requirements), preferable one of the 5 listed engine's.

Other specifications doesn't matter to much.

Berend

Old type SABB

Berend, you might get better feedback posting the same question on a fishing boat forum where the target audience work with their boats on a daily basis and their performance and costs are better monitored.

[Raggi_Thor]

Good point! Our old Volvo Penta works about 40 hours per year..

[Raggi_Thor]

I just checked some local builders of fishing boats, they deliver Yanmar, Cummins and Nogva (Deere) around 500HP..

[Raggi_Thor]

If you look at sites simmilar to
www.skipsrevyen.no
in your area you will see what machinery most new boats will have.

Last weekend I was out fishing in an old boat with a brand new small Yanmar. I noticed it was very quiet and smooth compared to our old Volvo, but you need more statistics than that

I voted John D. but I prefer this one much better

How about these engines?

http://www.steyr-motors.com/products/products.htm

I am a great believer in the 6 cyl in-line configuration for all 4 cycle internal combustion engines. It is the most inherently balanced configuration requiring the least counterweighting in the crankshaft.


...and then their 'hybrid model'

I heard a JP2 Lister ran 24/7 for 17yrs 4 months as gen in Africa. Dry sump, 2 oil tanks for oil changes and thermo-syphon cooling into a 2000l tank. Now thats what I call a motor!

Cummins

Dont know much about diesels, but I got 2 cummins for my build so they must be the best.

Starting up an old JP2 Lister:

Note the size of that flywheel, and compression release 'device' used to be able to hand crank it.

Look how much smoother this 3 cyl engine is:

and this 5 cyl:

We had a one cylinder lister water pump on the farm. If the thing back fired your arm was half off for a week.

Good motors though. Frosty would have done better with lister than with yanmar

Here's a motor with a bit of grunt.

Should keep any boat captain awake
I especially like the throttle response.
