SHIFTING PRINCIPLES: NON-REVERSE TYPE
(See Figure 1) There are 2 types of non-reversing type lower units normally used only on the smallest of outboards (2-3.5hp units). The first is a direct drive unit - the pinion gear on the lower end of the driveshaft is in constant mesh with the forward gear. The second is a Forward-Neutral shifting unit, in which shift assembly allows the drive gear on the propshaft to move in and out of contact with the pinion gear on the lower end of the driveshaft. In both cases, reverse action of the propeller is accomplished by the operator swinging the engine with the tiller handle 180 degrees and holding it in this position while the boat moves sternward. When the operator is ready to move forward again, they simply swing the tiller handle back to the normal forward position.
POWER TRIM/TILT SYSTEMS
INTRODUCTION
(See Figures 1 and 2) All outboard installations are equipped with some means of raising or lowering the complete unit for efficient operation under various load, boat design, water conditions, and for trailering to and from the water. The correct trim angle ensures maximum performance and fuel economy as well as a more comfortable ride for the crew and passengers. Though most Nissan/Tohatsu motors use a simple mechanical or gas-assist trim/tilt system, the larger (or more complicated) the model, the more likely you will find a Power Trim/Tilt (PTT) system. These systems can generally be found on models as small as 25 hp, but are more likely the larger the powerhead. Though particulars will vary, 2 basic system designs are used on these models. A single-ram unit is usually found on smaller (generally 25-50 hp motors) while a 3-ram system is usually found on larger (generally 60-140 hp motors). Basic service procedures are often the same on the varied systems, with exceptions of course for the additional components used on the 3-ram systems. Differences, when significant, are noted in procedures or illustrations.
