Yeah cycle it up and down by hand, each time refilling reservoir full, every now and then try the motor, sooner or later it will catch some oil and start pumping. or at least it should. usually its easier than what seems to be happening to you, why the new motor? could all this be related. valving stuck open .here
Your reservoir is full if at full tilt up it is full, tilt it up fill the reservoir, replace plug let the engine down, then tilt up and fill reservoir keep repeating without the motor until it bleeds enough for the motor to catch and do some by its self, keep repeating up and down, pretty soon it will be doing enough by it's self to make the final stages clearer, the oil will aerate so recheck fluid level an hour after final fill.
crisis averted there is a little ball bearing that sits inside the release screw fell out when i changed out the oil. With three attempts with the motor on and off and a sore back lifting the 100 up and down i knew there was something amiss. All working well now but to late to go fishing. The problem was the motor rusted through on the transom side so you could not see how bad it was until it was off. The new motor is covered in grease and rescue steel so that will never happen again!

Bargain. the end of frustration, all's well that ends well.
Operate the trim/tilt control several more times. Make sure that no more hydraulic oil has leaked from the lines you loosened, then re-tightened. Check the level of the oil in the reservoir.
Plastic catchment buckets
When your outboard motor's tilt and trim control becomes sluggish or "mushy" in its movements, like a newborn, it may need to be "burped" to remove air entrained in the hydraulic oil. The air has to have a place to escape from the system--one function of the hydraulic reservoir--and a bit of hydraulic oil is lost to the pressures of the process. Even so, the change in your tilt/trim control's performance will be noticeable and welcome.
Use an adjustable wrench to loosen the hydraulic lines to the pump/hydraulic motor. Set a plastic bucket beneath each loosened line as a catchment for leaking oil. Open the hydraulic fluid reservoir by removing the cap on top of the reservoir.
Add hydraulic oil to the hydraulic reservoir until the oil reaches the bottom of the filler opening. Leave the reservoir open. [links]
Operate the trim/tilt control several times. Oil will leak from the loosened lines into the catchment buckets. Re-tighten the loosened hydraulic lines. more
Need help with air bleed of trim motor of 200 HDPI
I thought you were to raise motor with trim pump, fill resevoir thru fill opening on back of bracket, then loosen bleed screw and let motor drift down. Repat steps until air noises stop.
Maybe that's what you were saying--
My 2001 200 hp HDPI will not trim down from full tilt up all of a sudden. The motor is getting power because you can hear it trying but from reading this post and others on the internet, it sounds like I have low fluid. I am confused by some of the suggestions on how to check fluid, which fluid to use and how to properly bleed air out of the cylinder. This post referred to manually moving the motor up and down to avoid the air and fluid foaming. well we all know that a motor this big does not want to be moved manually unless you have got Arnold Schwarzenegger handy to help you with it. Another question is why all of a sudden did I have a failure in this? I have twins and both have always worked flawlessly and at the same speed when trimming or tilting. I came down to use it a couple weeks ago and the starboard motor would not move from full up position. If it is a low fluid level, how did it happen all of a sudden. a small leak would lead to a slower tilt first right? or does the seal just go all of a sudden. Please help. my 9 year old wants to fish the Chesapeake for one more time this year while we have some Rockfish to chase!

OK, I know it's been a while since I requested this, but a new baby and old man winter and now I have a little time to address the issue before getting on the water.
I lift the engine (1986 200HP Yamaha) with the overhead hoist, open the fill port on top of the reservoir, then open(clock-wise) the manual release screw, let the engine down, and back up. A lot of fluid wants to come out the fill hole. If I put the plug back in when I let it down and pick back up, then When I do open it, there is air pressure blowing air/fluid back out at the top of the stroke also.
At what point do I close the manual release screw? When do I put the plug back in? Do I tighten it right away? I can not get at the plug when the engine is down, so?? I guess I'm hoping there is a trick I am not seeing, because there is a lot of air in the system that does not seem to want to some out. Everything Iput in lately comes back out. The only way I see to even add the fluid is with an oilcan pump spout.
HELP? lol
