Original Side-Power Zinc Anode
Older (4, 6 and) 7 hp models with 3-blade propeller. For Hallberg-Rassy boats it is for 7hp Bowthrusters.
Anode fitted in under the gearbox housing, not to the hub of the propeller as later Side-Power models.
Each Anode include 1 screw for Anode.
Change at least every 6-month. But please note that in some "hot" marinas it can be necessary to change the anode more frequently.
