The Martyr CMT-SGSL565A is an aluminum replacement bow thruster anode for select Sleipner / Side-Power thruster applications. It is designed to provide sacrificial corrosion protection for underwater thruster components and is commonly referenced as a replacement for 71190 and 51180 anodes. Published seller specifications list it at approximately 44 mm outside diameter, 20 mm height, with a 6 mm bolt hole and 20 mm hex mounting recess.
This is an aluminum anode, which makes it the correct choice for saltwater, brackish, and mixed-water use. Side-Power / Sleipner thrusters have been commonly paired with aluminum anodes for improved corrosion protection, and Martyr’s product line emphasizes aluminum as a primary corrosion-control option.

- Common replacement references: 71190 and 51180

Application / Compatibility
Common fitment charts for SGSL565A-style anodes list compatibility with select Side-Power / Sleipner thruster models including SP55S, SE60, SP65S, SP75T, SE80, SP95T, SE100, SR100, SX80, SX100, SH100, 7HP, and HYD100. Fitment references can vary by supplier, so this should be treated as a guide and confirmed against the exact thruster model and current anode dimensions before ordering.
Serial Number Fitment Notice
Please confirm fitment using your Side-Power / Sleipner thruster model, existing anode dimensions, and OEM part reference before ordering. If your unit uses a different diameter, recess shape, or mounting size, this will not be the correct anode.
When This Part Needs Replacement
Replace this anode when it is visibly wasted, pitted, reduced in size, or no longer making proper protective contact with the thruster assembly. Bow thruster anodes should be checked regularly during haul-out or underwater gear inspections, especially on boats kept in marinas or higher-corrosion environments. This is a small maintenance item that helps protect much more expensive thruster components.
Installation Notes
Remove the old anode, clean the mounting area thoroughly, and install the replacement so it seats correctly and makes full metal-to-metal contact. Do not paint the anode. Hardware inclusion can vary by supplier listing, so confirm whether mounting hardware is included with your exact source before ordering.

Parts Desk Insight
This anode protects a thruster that is far more expensive than the part itself. Replacing it before it is heavily consumed helps reduce corrosion risk on the thruster leg and nearby underwater metals. For Side-Power / Sleipner systems running in saltwater or brackish conditions, aluminum is the correct material choice for broad-use corrosion protection.
