Mitsubishi's marine footprint runs through UEC auxiliaries and MET turbochargers as much as main engines. Both reward buyers who verify rather than assume.
How to Send a Marine Spare Parts RFQ That Gets Priced Within 24 Hours
Most RFQs sit unpriced for days because they are missing one line the supplier cannot guess. This checklist fixes that — written from the receiving end of thousands of enquiries.
Daihatsu Spare Parts Buying Guide: DK28, 6DK20 and Auxiliary Engine Components
Daihatsu auxiliaries are everywhere in Asian-built tonnage and run punishing schedules. Their spares market is deep — here is how to buy the good metal in it.
IACS Class Requirements for Used and Reconditioned Marine Spare Parts (DNV, Lloyd’s, BV, ClassNK)
The question every superintendent asks before buying used: will class accept it? The answer is usually yes — with the right paper trail. Here is what surveyors actually look for.
Yanmar Spare Parts Buying Guide: N-Series, T240L Auxiliaries and High-Speed Engine Components
Yanmar auxiliaries run fast, hot and long — 900 to 1500 RPM for tens of thousands of hours. Used spares are excellent value if you respect what high RPM does to metal.
Essential Onboard Spare Parts Checklist: What Every Vessel Should Carry (IMPA-Based)
The difference between a 6-hour delay and a 6-day tow is usually a shelf in the engine store. This checklist covers what belongs on it — and what to stop overstocking.
MaK M20, M25 and M32 Spare Parts: Buying Used Pistons, Blocks and Crankshafts
MaK medium-speed engines are unforgiving of neglected cooling and brutal on pistons — which is precisely why their used spares need model-specific inspection, not generic assurances.
Reconditioned vs New Marine Crankshafts: Real Cost Comparison and When Each Makes Sense
A new slow-speed crankshaft can cost more than the vessel is worth and take a year to forge. A verified reconditioned shaft costs a fraction and ships in days. The honest comparison, with numbers.
Sulzer (Wärtsilä-Sulzer) RTA and RND Spare Parts: Buying Used Without Regret
Thousands of Sulzer RTA and RND engines are still earning their keep. Their spares market rewards buyers who understand fuel-equipment wear and liner scuffing — and punishes those who buy on photographs.
