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 the Onan, Fischer Panda or Northern Lights pages. Engine pages name the base engine when I've got a source. 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 tractor book 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 line is already on the engine page, so you can shop Kubota internals now.
I pull these numbers from public catalogues and third-party lists. They can be wrong. Check against an official source before you order. Methodology · All guides.
