The 70-SM51180 is a zinc bow thruster anode kit for select Side-Power / Sleipner thruster applications. It is designed to help protect the thruster gear leg and nearby underwater metal components from galvanic corrosion in saltwater use. Current fitment references tie this anode pattern to the older 51180 / 71190 style used across a wide range of Side-Power thrusters.
This is a zinc anode kit, making it the correct material choice for saltwater only. Current references commonly list the anode at approximately 1-3/4 in. x 3/4 in., and kit-style listings indicate the package includes the anode and screw.

Application / Compatibility
Common fitment references for this anode pattern include select Side-Power / Sleipner thrusters such as SP55S, SP65S, SP75T, SP95T, SE60, SE80, SE100, SR80, SR100, SX80, SX100, SH100, 7HP “A”, and HYD100. Some references also list older SM55 / SM75 / SM95 model naming. Fitment should always be confirmed against the exact thruster model and current anode dimensions before ordering.
Serial Number Fitment Notice
Please verify fitment using your Side-Power / Sleipner thruster model, current anode shape, and OEM reference before ordering. Matching by the 51180 / 71190 anode family is the safest method, especially on older thrusters where naming and replacement references may vary.
When This Part Needs Replacement
Replace this anode when it is heavily wasted, pitted, cracked, loose, or significantly reduced in size. Thruster anodes should be checked regularly during haul-out or underwater gear service because they protect a much more expensive thruster assembly from corrosion damage. Zinc is intended for saltwater service.
Installation Notes
Install on a clean bare-metal contact surface and do not paint the anode. Current kit-style references indicate an anode and screw are included, but some non-kit versions of the same anode pattern are sold without hardware, so it is worth confirming included contents when matching service parts.

Parts Desk Insight
This anode family has been used across a long list of Side-Power thrusters, which is why it shows up under several closely related part numbers. Another useful detail is that newer references often point customers toward aluminum alternatives, but this zinc version is still the correct choice when the goal is a traditional saltwater replacement in the original material type.
