2003 t-8
Trim up is acting up. I can get motor to go up an inch at a time if I bump the switch on and off till it’s up, trim down works just fine. Motor stays up just fine for weeks sitting on trailer. Motor runs fine when I hold “up” switch on. Seems low on fluid.
What screw to add more fluid?
Just went through this with my 2002. The first easy check is fluid. Open the Allen screw towards top of the oil reservoir and add fluid til it comes out the opening. Long story short everyone I talked to said don’t bother rebuilding or try to fix it,not worth it. I wish I would have just took there advice. I put about $50 in parts trying to fix it to no avail. Mine was doing same thing as yours and after trouble shooting I figured there was a bad check valve in the pump so I replaced all the valves and seats but still did not work. In the end I ended up buying a whole new trim assembly. $800 ouch. Wish I had a good answer but I would suggest you do what everyone told me and just bite the bullet.
Had a similar issue. I believe there was air in the system. After topping off the fluid, I ran the motor full up – full down about 10 times. Then topped the fluid off again. I believe I did this 3 or 4 times before the fluid stayed topped off.

Sorry for the late reply. I had the exact same thing happen. It was worse during cold weather. I took mine to a marine mechanic and don’t recall exactly what he did but I believe some screen or filter was clogged. The repair bill was around $200 for parts and labor and it worked fine afterwards. The parts were pretty minor.
The only problem I’ve had since was a couple of instances last fall on a couple of cold mornings when I trimmed the motor fully up and then it seemed to get stuck in that position. I don’t know if I’m low or fluid or what but now instead if leaving it in the full up position, meaning all the way up until it stops, I’ll tap the down trim switch to tilt the motor down an inch or two and I haven’t had a reoccurrence, even during sub-freezing temperatures in the winter months.
On a somewhat related note, the same mechanic repaired the throttle/idle on my T-8. I was never really please with how the T-8 would idle when it was new. I heard if you drilled out a cover plug that you could adjust a screw to make it idle better. I tried this and it really didn’t seem to make a difference. I’m not sure what this mechanic did, but my T-8 really idles down much slower now and doesn’t seem to increase or decrease rpms on its own, meaning without me adjusting the throttle. Before it would just seem to start revving higher or slower all on its own. I went from being okay with the T-8 performance to loving it. I don’t know why they don’t come from the factory like that.
