engine saging
Submitted by Sea goat on Wed, 2020-12-02 10:12
Hi guys.
i have a 200hp 4stroke mercury.
i have noticed over the last week or so that when i park it up i trim it up about midway. a few times by the next morning the leg is sitting on the ground. still seems to trim p and down ok, but just doesnt seem to hold the position.
any ideas? cant get it into the shop until early jan, and really want tobe using over the next few weeks for the crays.
cheers!
Goat.

Sounds like an internal seal is leaking.
Does anyone know where the love of god goes, when the waves turn the minutes to hours?

You may need to replace the seals in the trim rams. Worst case being replacing the ram itself. Had the same issue years back with my first boat

Ring the Merc dealer
They'll give you the best advice. Sucks on a new motor. Are they saying they won't do an immediate warranty job on it? From them, find out where the pressure valve is on the tilt/trim assembly. Worst case scenario, if it does actually fail to lift at the ramp, you undo this valve ( normally just a big flat-blade screwdriver required) and lift it up, then get someone to lock it back up, and put a block under it. I've had to do this myself with a motor some years ago. In the meantime, leave a block under it at home to take the weight. HTH.

Check that the manual relief
Check that the manual relief valve is tightly closed.
Have seen a few outboards do what yours is doing because it was1/8th of a turn out.

Don't know if you have a
Don't know if you have a torque wrench capable of checking but it should have the required torque for the relief valve in the manual as mine does for my Suzuki.

Put a block of thick wood between the end of the trim and tilt ram cylinders and the height adjustment bracket .Use pine or other softer wood to relieve strain while on the move or stationary . Will ensure a longer life of the trim and tilt system.

Correction to my previous post. the block of wood goes between the bottom and top of the engine mounting bracket. the principle is to keep strain off the trim and tilt mechanism. It will protect the motor and seals. You remove the block for operation of the motor in the water .All the best, i have not looked at the stern of the boat in ages..

This happened to my boat
This happened to my boat when I first got it... probably leaking out the seals.. I leave my motor fully down when not using it to keep the ram fully inside the Case ... they tend to dry up and when you move them. Straight down if a dry bit of built up salt or just dry The seal doesn't like it causeing it to eventually fail
also pressure on the ram and seal constantly when no in use kills them Also
it might just be a very slow leak just keep an eye on it untill fixed as long as you have some fluid and trims working. Ok you should be good.. don't use it if the trim is straining
