Mercury 135 gearbox

[JonathanMoore]

I have a 1990 Mercury 135. Every time I turn a corner the gearbox changes into neutral. Otherwise on straight the gearbox is fine.

i dont think its actually changing gears, i think your prop is ventialting/ sucking air. my prop does this also. but i know why mine is, its my own stupid mistake. how high is your motor in relation to the transom.<br /><br />your cavitation plate( just abopve the prop) should be about even, within an inch , with the very bottom of the boat. check this out and let us know

No. it is definitely slip[ping out of gear. It only happens on a right turn and I suspect a cable fault?

Re: Mercury 135 gearbox

I'm sorry if I appeared rude, I was trying to be brief. I have only purchased the boat last week and this was it's first trip. I just don't think it's a prop problem as it only happens turning one way. It may be a cable problem but if it is I do not know how I would solve it. Once again, apologies.<br />Cheers Jm

Re: Mercury 135 gearbox

So, after you make the turn and the engine pops out of gear, what procedure do you use to get it going forward again?

Hi Jayjeeper,<br />I restart the engine in neutral and it then runs fine until a right turn is made. Very strange.<br />Cheers<br />JM

Sounds like you're going to have to replace the shift cable... It's probably all gummed up....
