I see posts sometimes referring to marine part numbers. Are marine parts better? Just curious, trying to learn more information.

You will find that CAT seems to be the only engine manufacturer that pumps the HP out of their marine engines, the build them so the internals are tougher and more suited to the job and they take advantage to being able to use fresh water cooling to make sure temps don't get out of hand.
I think 580 was the upper limit on the mechanical 3406, 800 on the marine E model, 865 on the C15. Building a decent horsepower CAT is as simple as knowing the right part numbers to order.

Okay sled, let me do a little picking at your mind, I have found the listing for the 0R-8787s, but I have still yet to find the 0R-8789 any where on SIS.
I did find a few other odd numbers though while I was playing around on there this weekend like a 0R-8788, 0R-8791, and 0R-9943 all injectors. Im not sure on the HP rating of the engines they are from as they are gen sets, but I believe all of them were quad turbo 3412s.:thumbsup

Marine engines use the sea water to cool exhaust and air intake. as you know water removes heat faster than air. this allows higher HP as the heat can be controlled much butter. Cams,injection parts,timing ,etc may diffrer from truck to boat engines of the same family.
Mack was in the marine market before volvo stepped in. I recall the ME7(E7) 12 liter rated for 600HP. The ME9 (E9)16 liter was rated around 900HP+.

8789's were Genset nozzles rated anywhere from 519HP to 660HP. Yes, there WAS a 660HP 3406C used in a Genset. No good for the road with fixed timing, though.
The 8785's I used was from Serial Prefix 4TB. I listed it wrong earlier...it's been several years since I built my C engine. There are two HP ratings for the 4TB....500, and 580. Both have 99% the same parts as a C on road engine. Both ratings have the same 8785 nozzle.

I have been told the difference in the 8785, and 8789 is very minimal. I personally have never tried the 8789's. The 8785's gave me what I was looking for....so I stopped there.
My god father has a boat with 2 3406 mechanical assume C with 585 hp, he has another with 3406 E's or C15's 870hp each and another with twin 3412 or actually maybe C32 1450 hp each the V12's are twin turbo not quads.
there are some around here with 3406 E that are 870 hp mid 1990's, one of the guys that had a 3406 E 870 hp told me the only problem with them were you have to take the intercoolers apart every once in a while to clean the marine build up that will stop water flow, one guy blew his motor for not taking care of this, common maintenance for those engines.

depends on what motor and what you want out of it
sorry 3406e what would make good power and be reliable stilldepends on what motor and what you want out of it
ADEMII or ADEMIII? (As in does it have a crank timing sender?)
