Marine generators under 20 kW: Kubota, Shibaura, and own-design capsules
Cummins Onan Quiet Diesel, Fischer Panda, and Northern Lights sets in this scope. The guide names the industrial blocks they use. It names what stays capsule-OEM.
A genset puts a marinized industrial engine in a sound shield
Under 20 kW AC/DC, many marine generators follow the same base-engine story as a Beta. A Kubota or Shibaura industrial diesel sits in a capsule. The seawater pump, control gear, and end bell stay with the genset maker. Open /#/generators or the Onan, Fischer Panda, Northern Lights brand roots. Engine pages carry the base-engine blurb. Capsule catalogues land when I've extracted them.
Cummins Onan Quiet Diesel: Kubota (confirmed)
Lloyds type-approval and Onan install literature are the sources I used. Examples:
| Onan model | Kubota block | Notes |
|---|---|---|
| MDKBH | Z482 | 4/5 kW class |
| MDKBJ / MDKBW | D722 | 6-8 kW class |
| MDKAV / MDKBK / MDKBL | D1105 | 7/9 kW class |
| MDKAZ / MDKBM / MDKBN | V1505 | same V-series as a Beta 38 |
| MDKAW | V1305 | V1305 donor BOM may be thinner than D1105/V1505 in the books I've loaded |
| MDKDP | V2003 | |
| MDKDV | V2403 |
Internals cross to Kubota (oil HH164-32430 / WIX 51307 on V1505-class, and similar, when that filter family applies). Confirm on the unit. Onan numbers stay on the capsule, seawater pump, control, and sound shield. What you still buy marine applies inside a box.
Fischer Panda: mostly Kubota, one own diesel
Confirmed and likely Kubota rows include these maps.
8000i → Z482. 10000i → Z602 (I haven't loaded the Z602 book yet). 15i/19i → D902. AGT 6000 → Z482. AGT 8000 → D722. See others on the brand pages.
4000s Neo uses the Fischer Panda FPE320. I grade that row confirmed with no Kubota industrial code. Shop FPE320 internals for a 4000s Neo.
Some AGT mappings remain likely (check the nameplate before you order). EA300-class twins have a base-engine book I've loaded. Still check the plate for the subtype.
Northern Lights: Lugger / Shibaura
NL small sets in this scope map to Shibaura industrial codes (Lugger). I grade those maps likely from NL literature and Shibaura tables.
- M673L* → Shibaura E673L
- M773LW3G → S773L
- M843NW3G → N843 (I've loaded a base-engine parts list, so you can shop industrial internals)
- M844DW3G → N844L (same 84×100 family as Volvo D2-50/55)
Seawater and capsule parts stay Northern Lights numbers. If I haven't sourced it, the base-engine line is blank. I don't guess.
Shared discipline with propulsion engines
V1505 internals on an Onan MDKAZ match the V1505 family of a Beta 38. Filters may match. Pumps, anodes, and controllers stay Onan. Identify the donor from the genset plate (Kubota serial in the capsule).
FAQ
Is every Panda a Kubota? The 4000s Neo uses Fischer Panda FPE320. Other mapped sets use Kubota.
Which block do Northern Lights small sets use? Shibaura / Lugger on the rows I publish.
When is the Onan parts book coming? I haven't loaded the Onan parts book yet. The base-engine blurb is already on the engine page, so you can shop Kubota internals now.
