To help control the effects of galvanic corrosion, Ilmor Marine One-Drive stern-drives come with several anodes and an electronic anticorrosion system (I-CaPS) that protect the stern-drive in moderate corrosive conditions.
Galvanic isolators are available from the aftermarket (not supplied by Ilmor) to block these currents while still providing a path to ground for dangerous shock currents.
FEATURES AND CONTROLS Remote Controls The Ilmor One-Drive can be controlled mechanically with push-pull cables or electronically. Please refer to the Ilmor Engine Operation Manual or the Electronic Control System Operation Manual (if so equipped). Power Trim The power trim is used to accelerate the vessel onto plane, reach the desired engine rpm or vessel speed, and improve the performance of the vessel when there is a change in water or boating conditions.
Figure 2-9 Ilmor Cathodic Protection System The Ilmor Cathodic Protection System (I-CaPS) has a 20 A in-line fuse (Figure 2-10) in the wire which connects to the positive (+) terminal on the controller. If the fuse blows, the system will not operate resulting in a loss of corrosion protection.
