Engine Compatibility

Commonly associated with selected Volvo Penta petrol and diesel sterndrive applications that use a matching power trim / tilt fuse in the trim-pump circuit. Exact fitment can still vary by engine model, drive package, trim-system layout, and production range.

Serial Number Fitment Notice

Fitment may vary by engine model, drive configuration, and trim-system setup. Always confirm compatibility by engine or drive model and serial number before ordering. Volvo Penta directs users to identify the exact engine, shield, or drive when locating the correct spare part.

When This Part Needs Replacement

Replace this fuse when the original fuse is blown, heat-damaged, corroded at the terminals, or no longer providing dependable circuit protection in the trim and tilt system. It is especially relevant when troubleshooting a non-functioning trim pump or repeated overload condition in the related circuit.

Installation Notes

Confirm the exact application before installation and compare the replacement fuse to the original fuse rating and style during service. Because this part is commonly used in the trim-pump circuit, the surrounding fuse holder, terminals, and nearby wiring should be checked for heat damage or corrosion at the same time.

Alternate/Superseded Part Numbers

Related replacement references commonly associate this fuse with earlier numbers 856355, 853502, and 852939 in matching trim-fuse applications. Cross-reference use should still be confirmed by exact application before interchangeability is assumed.

Parts Desk Insight

If a trim fuse has blown once, it is worth taking a quick look at the holder and the pump wiring before just snapping in another one. A fresh fuse fixes the symptom fast, but checking the circuit now can save you from being back in the same spot later.
