The normal timing belt replacement interval on a 4-stroke outboard is 1000 hours or five years, whichever comes first. But an engine might need a service-related procedure that requires timing belt removal before then. This article deals with the safe removal and re-installation of the timing belt.
Gain access to the belt by removing the upper plastic parts and associated components. During dis-assembly, we encourage you to take photos (with your phone for example) to document the routing of various harnesses, hoses, etc. This simple act can prove to be a real time saver when you re-assemble these parts later on. Also, take care not to damage the wire-retaining clips on the powerhead. These clips must always be properly re-installed to ensure the
integrity of hoses and harness components.
