Book Excerpt: 1986-1994 Mercruiser Stern Drive Repair Manual


Although a propeller is usually a one-piece unit, it is made of several different parts (figure 13). Variations in the design of these parts make different propellers suitable for different applications.

The blade tip is the point of the blade furthest from the center of the propeller hub or propeller shaft bore. The blade tip separates the leading edge from the trailing edge.

The leading edge is the edge of the blade nearest the boat. During forward operation, this is the area of the blade that first cuts through the water.

The trailing edge is the surface of the blade furthest from the boat. During reverse operation, this is the area of the blade that first cuts through the water.

A smooth running, dependable marine engine is more than a convenience. At sea, it can mean your life. To keep your engine running right, you must follow a regular program of preventative maintenance.

Part of any preventative maintenance program is a thorough engine tune-up. A tune-up is a series of accurate adjustments necessary to restore maximum power and performance. In addition, some ignition parts which deteriorate with use must be replaced.

Engine tune-ups are generally recommended at 50 hour intervals. If the engine is used infrequently, a tune up should be performed at least once a season. Tune-up specifications are provided in Table 6 at the end of the chapter.

Late model engines may have a decal containing the engine serial number and tune-up specifications (Figure 39). If so equipped, follow the specifications given on the decal (even if they differ from those provided in Table 6).

A tune-up consists of the following:

    a. Compression check

    b. Ignition system work

    c. Carburetor inspection and adjustment
