I have a 1996 85 hp (mix your own oil) out board. It shakes violently at idle in gear and chugs in neutral and will die in N if I don't give it throttle via the idle lever. It runs fine at full speed, but like I said, shakes in gear and struggles to get to higher RPM. But, once there it's off like a rocket. I run 50:1 mix.

My alarm went off today at full speed. First time it's done that.

Also, my trim will go up but slowly falls down. Is that due to low fluid? Or, do I have a seal issue. I checked the manual bleed screw and it's tight.

And ideas what my issues may be?

Thanks, Brian
