Hi,
Welcome to the forum..
Would you be nice and turn off the all caps?

Have you checked fluid level for the trim pump?


p.s... Gas fumes have nothing to do with your problem, which in fact is a BIGGER problem than your current trim down problem.
Are you leaking fuel?
Trace all lines/hoses from the tank (and the tank itself) to the motor...
I hope you are running your blower to evacuate those fumes..btw

i agree gas fumes wont cause trim problem,but will cause much bigger problems,dont run boat until you fix source of fumes then worry about trim./

Like they said before, check the fluids. Sometimes they just get stuck in the upright position. Have someone push the trim button down and put a little weight on the lower unit. I hope thats all it is..:)

Re: Out drive stuck up position

have ya got a service manual?
if not.... http://www.boatfix.com/merc/Servmanl/srvcovr.pdf check out #14. it applies to your drive. and trim. save it to your drive. you'll need it in the future..

so what is your trim pump fluid level?
what happened when ya stood on the drive and energized the trim down/in button?
was the trim system removed for engine removal. if so. anything connection wise could be suspect.

i can't answer your question w/o reading about the down relief valve. my suspicion is that would be one of the latter things to check.

fwiw. trim systems don't look like something ya should be working on a lot w/o having a service manual on hand and reading proper procedures for diagnostics and repair.. they appear complicated to me...

Drive should not come down when pushing on the up button.

Re: Out drive stuck up position

Considering you just replaced the engine I would double check the lines are hooked up correctly.

Second check the wiring.

If they are good the third thing I would check is fluid, if the reservoir is full it dosnt necessarily mean your fluid level is good. If there is air in the line the system will not work, hydraulic pumps cant pump air. The fastest way to make sure your lines are bleed is to unhook them from the pump, put the ends into a bottle of power trim fluid, i believe automatic trans fluid can also be used but double check that. Make sure the end of the lines are submerged in the fluid, then lower the drive by hand by pushing on it. push it all the way down then lift all the way up. Do that a few times, if the lines have air in them it will sound like blowing bubbles in a glass of milk as the air is pushed into the bottle of fliud, once the lines are full it will be alot harder to move the drive up and down by hand. Once your sure the lines are full of fluid push the drive all the way down, give it a few min to allow the pressure on the fluid to even, then remove the lines from the bottle and hook them back up to the pump and make sure the pump is full and then try trimming it up and down with the controls. If you dont let the pressure even in the lines and you remove them to fast from the bottle of fluid they will squirt out fluid.

You may want to put something down on the ground to prevent the drive from hitting the ground. It will also be easier with a second person but can be done with one.

This is how I bleed mine when I rebuilt my engine last year, took all about 10-15 min and with the proper measures you will have little to no mess just a little spilled fluid.

See if that helps and let us know.
