the drives on my boat raise at different rates, Is there a way to adjust the speed that they rise for trim ?

First off, all boats have SLIGHTLY different trim speeds on the drives. This is normal. What is not normal is when it is SIGNIFICANTLY different.

so...Yes, and no.
You have to determine whether the speed difference is due to something in the pump or something in the drive.

1) Swap the pumps. If the slow drive now becomes the fast drive, then you know the difference is in the pumps. If the slow drive is still the slow drive, then you know the difference is in the drive.

if the pumps are where the difference is, it is likely that the electric motor on the slow one needs the brushes replaced and commutator cleaned. If this is the case, you will HEAR the speed difference in the motors. If they both SOUND like they are running the same speed, then you might have hydraulic leakage in the valves inside of the pump.

If the problem is in the drive, rather than the pump, it is usually one of the piston seals in one of the rams leaking. This is usually accompanied by the drive creeping in while underway. If you don't lose trim while running, it is not likely that the problem is in the drive.

Also, if this is a used boat, there is always the chance that somebody, somewhere, sometime, had to fill the trim system with a different fluid for some reason. Different fluids have different viscosities and will cause different trim speeds. Flushing all fluids out and refilling both sides with the same stuff can resolve that.

Best wishes.
