Service Manual 15-30 HP Routine Service [Oetiker Clamp Servicing]

Clamp Identification

Use Oetiker clamps for making hose connections. These clamps provide corrosion resistance, minimize the potential for abrasion of rigging components, and provide solid, permanent connections. The selection and installation of an Oetiker clamp is essential in the proper sealing of hose connections. The clamp identification numbers appear on the side of the clamp, near the top of the ear. Refer to Clamp Selection chart for dimensions.

DO NOT re-use Oetiker clamps. Fuel leakage could contribute to a fire or explosion.

Clamp Selection

To select the correct size Oetiker clamp, measure the outside diameter of the hose when installed on the fitting.

Chose a clamp so that the outside diameter of the hose is approximately in the middle of the clamping range of the clamp.

Clamp Installation

A constant stress should be applied to close the ear clamps. This method ensures a positive stress on the hose and does not result in excessive com pression or expansion of the band material.

Use only Oetiker recommended tools to close Oetiker stepless clamps.

Oetiker pincers are available in the Evinrude/ Johnson Genuine Parts and Accessories Catalog.

• Position correct size clamp over hose.
• Install hose on fitting.
• Close clamp ear fully with Oetiker pincers (pliers).

Clamp Removal

Method 1: Position Oetiker pincers across clamp ear and cut clamp.

Method 2: Lift end of stepless clamp with screwdriver.

Method 3: Use Oetiker pincers (pliers) to grip clamp. Pull clamp off of connection and discard.
