New 40hp Merc 2S on a 13' Sport will not stay in the raised position, it will eventually drop the prop housing into the water. Is there an adjustment that can be made or must I use the locking pin?

Make sure there is enough fluid in the power tilt and trim system. Make sure the fill plug is tight and not leaking air as it will loose pressure. My guess still is that it is low on fluid from the factory/dealer.

Most trim and tilt units have a bleed screw that is used if the motor must be raised manually (ie - dead battery and need to load onto trailer). If this is not tight enough, the tilt unit will bleed and the motor will slowly drop. Often, it is a different screw from the fill plug.

Thanks Guys,
I'll try to check the level and plugs. Can this be done with the boat in the water?

I would advise not in the water, if there is a plug loose then water could seep in if the trim unit sits a little below the water line.

the manual on my new evinrude ficht motor specifies to use the tilt lock to hold the motor in a the tilted position for any length of time to reduce strain on the system.

if its new it shouldn't do that, but it is probably a good idea to get used to using the locking pin. It can't hurt and can only reduce wear and tear on your tilt system over the long haul. if you keep it on the water, it will just be subject to more bouncing around which is probably even harder on it.

get if fixed under warranty and then use the locking pin.

I think you may have hit on it, the boat is tied-up at the dock and is subjected to heavy bouncing around. That can explain why it happens over a longer period of time. I'll start to use the pin.

i don't think it should really droop over a couple of days. I keep my D15 on a busy waterway and all last year on my old motor (Johnson 70HP 2 stroke) I kept it up on the trim and tilt without using the pin. you probably do have a bit of a leak in yours, I would think (but then I have never owned a merc, so I don't have alot of experience with them).

the pin is still a good idea anyhow.
