Another trim question (06 VP 5.0 GXI/SX)

[Chewey]

I've got a new-to-me 06 Chaparral 220 SSI with a VP 5.0 GXI with the SX drive and I'm wondering about my trim. When the trim is all the way down, there is still about 2" of cylinder left when the motor loads up and the drive stops moving. The gauge says it's all the way down, but it looks to me like it should go down more. (see below)

I've looked in the Clymers manual and there's little info on the system except to calibrate the gauge to the system. So my questions are: Should the trim go farther down? Also is it correct that the SX drives do not have limit switches, but just stop moving when they hit their mechanical limits? Cause it sounds like the motor is trying to continue to move the drive (this happens for both up and down), but the motor sounds like it is under a huge load once the drive stops moving.

Incidentally, when the drive is all the way up, gauge shows that is down 1/8. The rams measure 23 1/8" from center to center when in the up position.

Any help is much appreciated.

That position appears to be down all the way to me. You are correct, no trim limit switch. The additional load on the trim system at full up or down is also normal, and typical for most hydraulic systems.

I have the same situation but my trim gauge never goes to an "in" reading. In my ignorance I assumed the polished shaft extending the two inches was supposed to retract into the cylinder??

Ayuh,........ How ya Doin' RP,..... Been awhile since I seen you posting.....

I Agree almost completely with RP,.....Everything looks,+ sounds pretty Normal here with you're Volvos....
On trim rams in general, there's usually several Inches of polished shaft exposed, when fully collasped.....

With My old Mercruiser,... The pump Labors at full up,...
But at full Down, it Unloads,+ run Wild....
