Detent update

In 1992 OMC made a detent revision added a centering slot, that then position the unit in a fix neutral location. Set up with the new detent is easy. To install screw shifter rod in clockwise 8 turns. This should give you a reading of 7.156 inches from outdrive base to top of the rod end cap. This stops the clutch dog movement and lug wear due to poor set up. New angle machined on the detent allows for much easier shifting. This faster engagement of clutch dog and forward gear movement saves on 5 degree lug wear or shift cable replacement every 4 to 5 years.

Note if you are replacing the clutch dog there are only 4 main reasons why.

Shift cable has stretched over time due to poor detent (old type) and forcing it into forward or reverse gear after impacted damage to gears.
Engine rpm is to high (old fuel to new fuel). Carburetor adjustments should be made with using 0 to 1000 RPM setting on engine tack. Readings should be as follows V8 engine (550 rpm), V6 (575-600 rpm). Adding a door type spring to carburetor linkage we help insure that cable return to proper location in case there is problem with cable being stretched.
Use of a stainless steel propeller where the stall out rotation rate is slower due to weight, moving from forward to reverse to quick will damage lugs. In many cases this will break a tooth on the pinion gear.
Outdrive has a lot of running hours.
