Universal 5411 or M15
 
I'm a bit confused when It comes to the Universal engine in my 1984 N-28 II. The original survey 10 years ago had the engine listed as a 5411. The dip stick is labeled Z-500 and its antifreeze cooled so its my understanding the engine is a M15 (16 HP, 45 in^3) not the 5411 (11 hp, 31 in^3). Are there other ways to tell the difference. (still cant up load pictures)

5416 was the universal 16 hp engine Donald. I have one in my boat. it was the Z-750 kubota engine used in the kubota L-185 tractor

The Z500 seems to be this.

Type: Kubota Z500-1A
Fuel: diesel
Aspiration: natural
Cylinders: 2
Valves: -unknown-
Bore/Stroke: 2.625x2.75 inches [67 x 70 mm]
Displacement: 31 ci [0.5 L]
Power: 12 hp [8.9 kW]
Cooling: liquid
Coolant: 3.2 qts [3.0 L]
Compression: -unknown-
Rated RPMs: 3000
Starter volts: 12
Starter power: 1.1 hp [0.8 kW]

The 5411 and M15 are essentially the same engine based on the Kubota Z-500 industrial engine. The 5411 became the M15 at the end of its production run. If yours is fresh water cooled, not raw water cooled, i.e it has a heat exchanger, it was probably converted at some point.

This Universal Engine History is the web site I was referring to in my original post. It says "In 1977 the Model 5411 was introduced. It was a 31 cu in, 2 cylinder raw water cooled diesel producing 11 hp @ ? rpm, based on the Kubota Z-500 block, and fitted with a Hurth HBW-50 marine transmission." and "In 1982 the Model 5411 was replaced by the Model M15, a 45 cu in, 16 hp, 2 cylinder, fresh-water-cooled, based on the Kubota Z-500 block and fitted with a Hurth HBW-50 marine transmission." Is this web site in error?

Yes, that site is incorrect. Looks like they did some copying/pasting and mixed things up. Here's a link to a similar history. Note the similarity to the wording. And the slightly different commentary about the M15.

The Kubota engine number your engine is based on should be stamped on the oil dipstick. The 5411/M15 is a Kubota Z-500.

Thanks Jim, I almost forgot why I cared, then I remembered I was considering replacing the old three engine mounts but I needed to know the proper engine weight which leads me back to which engine I have. Thanks again.
