I have two Bravo 1's, one trims faster than the other. Is there a way to increase or decrease the speed so they stay in unison?

Example: As I hit my trim switch for a second the port ends up at 1 and the starboard at almost 2. I know the indicator is arbitrary but they are actually uneven... One drive is actualy trimmed higher becasue one pump is faster. How can I fix this?

I've checked the fluids and they sound identical.
( I am not talking about the stops either)

The cap where the ram comes out of the trim cylinder is aluminum. It can corrode and pinch the ram to the point where the drives operate at different speeds. The effect should be greater trimming down since the down hydraulic pressure is lower than the up hydraulic pressure. Rebuilding the rams on the slower side could help.

BTW this problem is most likely to occur on an older boat. Your post doesn't say the age of the boat.

Run thinner oil in the slower pump. It will help a little bit.

the boat is a 2004 but it has 300+ hours on it. This will occur in fresh water?

I suppose the corrosion issue can happen in fresh water but I don't know for sure. One thing, the effect from pinching the rams is more pronounced trimming down since the down pressure is lower than the up pressure on the drive. Do you have the same problem trimming up and down??

My trim rams were almost dangerous due to the different down speeds slowing down from a high speed blast since I have a single up/down switch on the throttles. I fixed one set of rams and now need to rebuild the other set but I boat in brackish water. Was your boat operated solely in fresh water or did it have a stint in salt/brackish water?

Try asking Mr. Gadgets or Mobilemercman on a PM. Maybe they can come up with a troubleshooting plan. The rebuild kit is expensive when you add the cost of the cylinder caps so you will want to make sure that you actually need a rebuild before investing in the kits.

I just had to replace my port side pump motor, and now have the same problem. (new pump trims faster) Would be nice if you could adjust them somehow.
