Ford Lehman, Sabre and Mermaid diesels use Ford industrial base engines
Lehman, Sabre and Mermaid marinize Ford Dorset, Dover and Dagenham blocks. Buy internal parts as Ford spares.
The British Ford marinizers
Three British marinizers use Ford industrial and tractor base engines. The marques are American Diesel/Lehman (Ford Lehman), Sabre and Mermaid.
The Ford families are Dorset, Dover and Dagenham. Those families cover four-cylinder and six-cylinder diesels. Trawlers and motorsailers still use these slow-turning engines.
Internal parts cross to Ford industrial numbers. The marques share many wear items because they share the base engine.
Ford Lehman to Ford base engine
| Lehman model | Base engine | Cyl |
|---|---|---|
| Lehman 4D220 | Ford 592E (Dagenham 220ci) | 4 |
| Lehman 80 (4D254) | Ford 2712E (Dorset 254ci) | 4 |
| Lehman Super 90 (SP90) | Ford 2722E (Dover 254ci) | 4 |
| Lehman Super 135 (SP135) | Ford 2725E (Dover 380ci) | 6 |
Sabre to Ford base engine
| Sabre model | Base engine | Cyl |
|---|---|---|
| Sabre 80 | Ford 2701E (Dorset) | 4 |
| Sabre 100 | Ford 2712E (Dorset 254ci) | 4 |
| Sabre 120 | Ford 2715E (Dorset 380ci) | 6 |
| Sabre 150 | Ford 2704ET (Dorset 363ci turbo) | 6 |
Mermaid to Ford base engine
| Mermaid model | Base engine | Cyl |
|---|---|---|
| Mermaid Meteor | Ford 2701E (Dorset) | 4 |
| Sealion 120 | Ford 2712E (Dorset 254ci) | 4 |
| Merlin | Ford FSD425 (York 2.5 DI) | 4 |
| Mistral | Ford 2704ET (Dorset 363ci turbo) | 6 |
JCB exception
| Mermaid model | Base engine | Cyl |
|---|---|---|
| J444NA / TA / TCA | JCB 444 Dieselmax | 4 |
The Mermaid J444 engines use JCB Dieselmax blocks (PowerTorque marinization). Cross those internals to JCB 444 part numbers.
Shared parts across the Ford marques
The engines share consumables because they share Ford base engines. The Sabre 150 and Mermaid Mistral both use the Ford 2704ET. Those two match closely.
The Sabre 120 (2715E) and Lehman SP135 (2725E) use related six-cylinder Dorset and Dover base engines. Owners report that the oil filter and raw-water pump impeller cross.
Example oil filter: WIX 51515 / Napa Gold 1515. Example impeller: Jabsco 1210-0001. See the impeller and oil filter charts.
Ford marinizers changed base engines inside a model name. Some Sabre 80 engines use a later 2711 or 2712. Some Sabre 120C engines use the Dover 2725E. I grade several impeller and filter crosses as likely. Confirm the part before you order. See Methodology.
Marine hardware you still buy as marine
The heat exchanger (or keel cooler), raw-water pump body, marine gearbox, and wet exhaust stay with the marinizer.
The Mermaid J444 family uses JCB Dieselmax (PowerTorque). Internals go to JCB 444 numbers.
Shared-wear claims stay likely until you match the pump and can on the engine. Those claims include WIX 51515 oil filter on Sabre 120 / Lehman SP135, and Jabsco 1210-0001 impeller.
How to confirm the base engine
Ford marinizers changed base engines inside a model name.
- If you know only a broker listing, read the casting on the iron.
- Match 2712E versus 2725E. A "Sabre 80" in an ad still needs the casting.
- If the raw-water pump is a belt-driven Ford 2700-series, use that impeller family.
- If the pump is a Johnson F5B-9, use the other impeller family.
- See the impeller chart Ford paragraph (Jabsco
920-0001/ Sierra18-3018). - Johnson
09-801Bis single-source. Verify that number.
FAQ
Do Lehman, Sabre and Mermaid use the same engine? They share Ford industrial families. Each marque keeps its own marinizing book. Sabre 150 and Mermaid Mistral both use Ford 2704ET. That pair is the closest same-engine claim on this page.
Can I use tractor Ford filters without a check? Thread and height still matter. Treat WIX 51515 as a lead. Confirm thread and height.
