Merc Promax controlled by Cummins???!!! (pics)

[silverbullet02]

I was out playing with the boat today, and since I have this bad habit of randomly taking things apart, I pulled the ECU off the motor and popped it apart to take a look inside and see if there are any adjustments. It's a '97 225 PM and the circuit board says Cummins Electronics! How about that!

Brian :thumbsup:

That’s funny… :smiletest:


I just hope you don’t find any Briggs & Stratton parts in her. :p :p :p

[flabum1017]

merc did that on purpose, they knew you would be pulling it apart..... those guys........

YUP,

assembled in the USA with Chinese components:eek:

Makes sense why them darn things are so smokey!!!! That's really cool. If I remember right Cummins used quite a bit of Motarola stuff so it could be that badged Cummins. Either way, pretty trick.

Does that mean I can fill up with Diesel now instead of going through the pre-mix routine................LOL

[njj502]

Give it a try and post the results!!! :reddevil:

[Liberator*21]

I'll get right on that and let you know.......................:p:reddevil:

[njj502]

Marine Engineering Group (posts on here) had a prototype that I went and looked at for military application. Good product, well executed prototype, but I believe the marketing just wasn't right.

YUP,

and he is a member here, Maritime_eng.

I don’t know if it was so much the marketing but more so the cost, weight, performance etc. A diesel outboard will have a VERY limited market. I could see one on a toon, commercial fishing rigs and other workboats. Also would be good where gasoline is not advisable due to flammability. I think it's a great idea but somehow the cost would have to come down to justify it. Fuel consumption should be excellent though.

[Liberator*21]

In concept I'd agree there would be a good use for a hard working diesel outboard, but as you stated there's something that's kept that from happening, cost, weight etc. what ever it might be................

Yanmar made diesel outboards. http://www.yanmar.com.au/marine/d_series/dseries.htm

[njj502]

I've seen one of these in my day and it was in a scrap yard with hole in it. I can't imagine they would live very long at 4500 RPM if ya held em there all day. Yanmar is a very good product but that's quite a bit of RPM for sustained usage.

Mercury makes a jp-8 outboard for military use JP-8 and diesel are really close. The navy doesn't want take carry gas anymore on ships so the more things that run off of JP-8 the better.

[sjcolwell2]

It would be twice as heavy also !

Here's a turbo diesel these folks created...

Sukuki also made a 25hp diesel it cost 4x what the 2 stroke cost
