I have an older Honda 4 stk 7.5
Had a similar problem with popping out of reverse when under load. Most inconvenient when manouevering in a marina!

There is a long rod from the gearbox area to the shifter that runs up the shaft and is threaded on the top end. The shifter knob causes the rod to move upwards and downwards to change the gears from fwd, neutral, reverse. The locations of these gears on the shifting lever are adjusted by the threaded cap on the top end of this rod. Moving the cap upward or downward by turning this cap clockwise or counter clockwise is how the gear shift positions are adjusted on the Honda.

I had taken the engine to a Honda dealer who "adjusted" this for me. They said it was not in quite the right position. Will still ocassionally pop out of reverse but not as often or as easily as before. The reason the adjustment was needed was age and the fact that I had the shaft removed to replace the impellor and some seals.

My engine is 1979 model. I have in some years replaced parts myself and done my own winterizing and in others taken it to the dealer. The dealer never seems to do anything different than what I have done but the whole engine runs better after they have had it. I would recommend you look a little deeper and find someone who services Nissans as I have heard they are a good engine.

Good Luck
