Guides

I've written these to help you name the tractor or industrial block behind your marine engine, then look up impeller, oil-filter and fuel-filter numbers.

Start here

Why most marine diesels use a tractor engine Work out the base engine, then buy internal service parts through agricultural and industrial channels for a lot less. How to use MarineDieselXRef Find your engine, read the base-engine line, open the industrial list, and use a part page as a lookup. What you still buy as a marine part Heat exchangers, raw-water pumps, gearboxes, anodes, and wet exhaust stay marine. Internals follow the base engine. How to identify the base engine from the marine model Read a marinizer plate, a Kubota or Mitsubishi casting, and the confidence grades here. If the grade is only likely, don't order pistons yet.

Base engine

Beta Marine marinizes Kubota industrial blocks I've mapped each Beta diesel to its Kubota base engine. Order internal service parts as Kubota agricultural spares. Nanni Diesel marinizes Kubota industrial blocks I've mapped Nanni small and mid-range diesels to a Kubota base engine. Order internal service parts as Kubota agricultural spares. Universal Medalist marinizes Kubota industrial blocks I've mapped Universal Diesel and M-series engines to a Kubota base engine. Order internal service parts as Kubota agricultural spares. Solé Diesel marinizes Mitsubishi industrial blocks I've mapped Solé MINI and SM ranges to a Mitsubishi base engine. A few families use Kubota, Mazda, or Nissan. Order internals as industrial spares. Westerbeke marinizes Mitsubishi industrial blocks I've mapped Westerbeke W-series and B-series diesels to a Mitsubishi base engine. Two engines use Perkins. Order internals as industrial spares. 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. 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. Volvo Penta MD27, MD29 and MD32 use Peugeot Indenor XDP base engines MD27, MD29 and MD32 marinize Peugeot Indenor XDP six-cylinder diesels. Internals cross to 113 confirmed Indenor numbers. Perkins 4.108, 4.154 and 4.236 marine versus industrial Perkins marine 4.108M, 4.154M and 4.236M use Perkins industrial base engines with marine cooling. Buy internals on the industrial channel. Volvo Penta own-design engines versus marinized base engines Find which Volvo Penta engines are Volvo design, Indenor, Prima, or Perkins-Shibaura. Match the family, then shop that industrial channel. Yanmar GM and YM engines have no tractor base engine Many Yanmar sailboat engines are Yanmar marine designs. Industrial TNE cousins help only where the page says so.

Cross-reference chart

Marine raw-water pump impeller cross-reference chart (Jabsco / Johnson / Sierra) Cross-reference chart for marine diesel raw-water pump impellers. Jabsco, Johnson, Sierra, and JMP equivalents group by pump for Beta, Volvo Penta, Ford Lehman, Sabre, BMC, and more. Marine diesel oil filter cross-reference chart (Kubota / WIX / Fram / Fleetguard) Oil filter cross-reference for Kubota-based marine diesels (Beta, Nanni, Universal). Covers the Kubota HH150 and HH164 spin-ons and WIX, Fram, Fleetguard, and Mann equivalents. Marine diesel fuel filter cross-reference chart (Kubota / WIX / Baldwin / Fleetguard) Fuel filter cross-reference for Kubota-based marine diesels (Beta, Nanni, Universal). Covers the Kubota 15221-43170 spin-on and element filters with WIX, Baldwin, Fleetguard, and Donaldson equivalents. Anodes and saildrive wear: measure, then cross-reference How marine diesel and saildrive anodes interchange (Tecnoseal, Martyr, Sierra). Measure pencil zincs versus collars. Match thread pitch before you guess a model.
