Re: 1989 Force Grinding going into gear

Some grinding is normal as the gears are not syncronized. Do not ease it into gear. Put it in gear with a quick motion. When is the last time you changed the L/U oil and checked for water intrusion? Also if you find large pieces of metal in the oil you may have some gears to replace.

the lower end oil has been changed every fall since the boat was new in 1989 there is no water intrusion or shavings i do not know if it was needing a new throttle cable or not if it does which end does it need throttle end or engine end

maby the engine is idling to high before you put it in gear i had the same problem and i fixed it by lowering the idle alittle.

First, remove the cable inside the engine. Now try to move the shift linkage by hand. If it is so tight you can hardly move it, the lower shift rod seal has swelled and tightened. It needs to be replaced.

If the likage moves OK, then you need to re-adjust the shift linkage. It is biased a little toward reverse so when you try to put it into forward, the engine starts accelerating before the drive dogs are fully engaged. They bounce off each other until enough travel has been acheived to let them lock-up.

It is not too difficult: The shift linkage is on the side of the misleg behind the lower shroud. There is a long hex coupler threaded opposite for the upper and lower section of shift rod. Since forward is down, you need to turn the coupler in the direction that lengthens the rod. EASY DOES IT! 1/2 turn at a time. If you go too far, it may not go into neutral or it may do the same thing in reverse or not go into reverse at all.
