It took me a lot of work to get my Mercury 402 Longtail back to life after 15 years playing dead in a barn.. Now it is running more ore less, but it seems that it does not like the water. When on the boat, forward is not a problem, but as soon as i go in reverse, it tries to climb in the boat with a big growl....

I had the lower-unit removed to rebuild the waterpump, and i noticed the plastic cam wich should lock the motor down was worn. I replaced it with a stainless one, but i think it is not in position. What is the right way to be sure it is alligned as it should? I know i need to take the lower unit of again, but i don't want to do it more than once....

The ramp on that 'cam' is used to engage the 'tilt' lock.

Actually it dis-engages when shifted into Forward, engages when shifted into Neutral and stays engaged when shifted into Reverse.

When you drop the foot this time pay attention to the tilt lock mechanism, the rod that rides against the cam, watch how the ramp lifts/drops as the shifter rotates, re-index in Forward gear such that the tilt lock is disengaged, reassemble.

So,the cam should lock in neutral also? I thought i should be able to lift the motor when in neutral and only lock in reverse?:confused:

On my Mercury 650 the only way to disengage the tilt lock is to put the motor in forward gear. In neutral it's locked. I guess all tilt adjustments will have to be done from inside the boat.

Merc wanted to be sure that the motor is trim locked BEFORE it engages in Reverse gear, the only sure way was to lock it in Neutral and un-lock for forward when you want it unlocked so as to be able to 'kick' up if you hit an underwater obstruction.

Re: Outboard climbing inboard

As far as i can tell, my setup seems right. When the motor is not running and in reverse or neutral, it is locked. To take the motor up i need to have it in forward. But last saterday on the river, i tried to back down from the ramp and kicked up. The only diference was that the motor was running at that time, and i must confess, it was running a little fast (app.1500 rpm) when i kicked it in gear. It was not running idle verry well, so i kept the throthle a little open....
