FITMENT NOTE:
This is a small-range (5.3mm-11.8mm) Oetiker clamp kit identified by WSM catalog reference 990-505. NOTE: This is the SMALL-DIAMETER kit — different from the 990-500 (10.3mm-41mm Mercury powerhead range). Verify your hose diameter is within the 5.3mm-11.8mm range before ordering. Oetiker ear clamps require an Oetiker installation tool for proper crimping — standard pliers will NOT properly install these clamps. The kit is suitable for various marine engine brands and applications where small-diameter Oetiker clamps are specified.
