Re: 1981 40 Hp Merc , NO reverse... HELP
Have you had the waterpump replaced recently? Has it ever worked properly for you? More often than not, when a Merc unit is stuck in forward, it means the lower and upper shift rods are misaligned. Merc units are spring loaded into forward as a fail-safe, so if the unit was serviced and then reassembled to the motor improperly, you will get the problem you describe...
