Hello. My name is Tan.

Will the drive tilt up? Do you hear the trim motor running?

Does the trim motor quit working when it gets to a certain point of the drive trim 3/4?

Customer: replied 1 year ago.
It just buzzed indicating it hit the bottom set point I just need to know how to set the trim stop on lowering it
Expert:  Tan replied 1 year ago.

Does the drive go all the way down? There is no stop this is the purpose of the down relief valve. That is the buzzing sound that is the drive hitting the stop and the valve bypassing pressure.

What do I need to do to get it to go lower
Expert:  Tan replied 1 year ago.

If the pressure relief valve is buzzing then the drive is down all the way. If it is stuck at 3/4 of the way down you have something wrong with one of the trim rams. Disconnect the trim rams at the rear of the drive now trim the rams all the way down. Do they fully retract?

When I bought the boat the dealer said that they can set the trim so it does not go down all the way
Expert:  Tan replied 1 year ago.

Why would you not want the trim to go down all the way. The boat will not run correctly with drive in that position it won't evn get on plane. Did you do the checks I ask? The dealer is incorrect.

Could I get the model number of your drive please?

The last time I remember a trim limit on Volvo was 1997 and it was to limit up trim only. And these were bypassed and removed as they didn't work.

It would work better to pull skiers out of the holeOnce out plane it out
Expert:  Tan replied 1 year ago.

Tilting the drive up doesn't help with pulling skiers out of the water you want drive all the way down. Id the drive is up any the boat won't get on planes as the bow of the boat will go straight up in the air.
