Guides

Plain-English guides to marine-diesel parts cross-referencing: which tractor/industrial block your engine is marinized from (so you can buy the far cheaper base-engine part), and the aftermarket impeller, oil-filter and fuel-filter equivalents for the common wear items.

Why most marine diesels are marinized tractor engines — and how to buy the cheaper part Almost every small marine diesel is a marinized industrial or tractor block. Identify the base engine and you can buy internal service parts far more cheaply through agricultural and industrial channels.

Base engine

Beta Marine engines are marinized Kubota blocks — buy the tractor part Every Beta Marine diesel is a marinized Kubota industrial engine. Here is the Beta-to-Kubota block map, so you can order internal service parts as far cheaper Kubota agricultural spares. Nanni Diesel engines are marinized Kubota blocks — buy the tractor part Nanni Diesel's small and mid-range engines are marinized Kubota industrial blocks. Use the Nanni-to-Kubota map to order internal service parts as cheaper Kubota agricultural spares. Universal (Medalist) marine diesels are marinized Kubota blocks — buy the tractor part Universal Diesel and M-series marine engines are marinized Kubota industrial blocks. Use the Universal-to-Kubota map to source internal service parts as cheaper Kubota agricultural spares. Solé Diesel engines are mostly marinized Mitsubishi blocks — buy the industrial part Solé Diesel's MINI and SM ranges are marinized Mitsubishi industrial engines (with a few Kubota, Mazda and Nissan exceptions). Use the map to source internal parts as cheaper Mitsubishi spares. Westerbeke marine diesels are marinized Mitsubishi blocks — buy the industrial part Westerbeke's W-series and B-series diesels are mostly marinized Mitsubishi industrial engines (with two Perkins exceptions). Use the map to source internal parts as cheaper Mitsubishi spares. Ford Lehman, Sabre & Mermaid diesels are marinized Ford industrial blocks — buy the Ford part Ford Lehman, Sabre and Mermaid marine diesels are marinized Ford Dorset, Dover and Dagenham industrial/tractor blocks. Use the map to source internal parts as cheaper Ford spares. Volvo Penta MD27, MD29 & MD32 are Peugeot/Indenor XDP blocks — buy the Indenor part The Volvo Penta MD27, MD29 and MD32 are marinized Peugeot/Indenor XDP 6-cylinder diesels. Internal parts cross to far cheaper Indenor/Peugeot numbers — with 113 confirmed cross-references.
