Trim motors for Yamaha engines

How do you choose the right Yamaha trim motor? To avoid any compatibility error, the Yamaha OEM reference remains the main criterion. Ideally, it should be compared with the reference on the original part or checked using the outboard engine serial number. Before ordering, also check the following points: ●      The connector: 2-wire, 3-wire or 4-wire trim motor depending on the installation. ●      The mounting: 3-screw or 4-screw plate. ●      The plate diameter: essential to ensure installation without adaptation. ●      The screw centre distance: compare it with the old trim motor. ●      The length and diameter of the drive shaft: they must match the hydraulic pump. Important: the compatibilities below are provided for guidance only. Yamaha used different installations depending on year, serial number and version. If in doubt, always check the exact reference before replacing the part.

Before replacing the electric motor, it is important to confirm the cause of the fault. A trim problem can come from the motor, but also from the relay, power supply, hydraulic pump or cylinders. ●      The trim no longer goes up or down: first check the battery, fuses, electrical connections and trim relay. A faulty relay can make the system completely silent. ●      The electric motor runs but the outboard does not move: check the hydraulic oil level, the condition of the pump and the tightness of the manual release screw, also known as the by-pass. ●      The trim works intermittently: an oxidised terminal, a poor contact or water ingress into the electric motor may be the cause. ●      The motor heats up or makes an abnormal noise: this may indicate worn brushes, internal corrosion or excessive load on the hydraulic system. ●      The motor runs but does not lift the outboard under load: the problem may come from the cylinders, a worn internal seal or a hydraulic leak rather than from the electric motor itself. Hydraulics, seals and watertightness: sensitive points A faulty trim motor can sometimes be the consequence of a wider problem in the tilt and trim system. It is therefore advisable to inspect the cylinders, scraper seals, pins and the overall condition of the hydraulic unit. Damaged cylinder seals can let water in, especially in marine use. This ingress damages the hydraulic oil, promotes corrosion and can ultimately damage the pump or electric motor. An oil level that regularly drops generally indicates a leak that should be dealt with quickly. Yamaha trim maintenance To extend the service life of the system, rinse the outboard thoroughly after every trip at sea and operate the trim several times during rinsing. This helps remove salt around the cylinder rods. It is also recommended to grease the pins, trunnions and articulation points with a suitable marine grease. An annual check of the hydraulic oil level and seal condition helps prevent many failures. New or used Yamaha trim motor? A used trim motor may seem economical, but its internal condition is difficult to check without disassembly. The brushes, commutator, seals and watertightness may already be worn or weakened. For a part so exposed to moisture and so important for safe outboard use, a new or quality reconditioned trim motor generally remains the most reliable choice. Below you will find our selection of trim motors compatible with Yamaha 2-stroke and 4-stroke outboards. To confirm compatibility, have your OEM reference or engine serial number ready.
