I noticed yesterday morning that when it is fairly cool outside my power trim on my GTR35 is very slow. As the day warms up it speed up anyone have any suggestions on how to correct this.

mine does the same, this is normal.

Is it possible that the voltage on the battery gets low and causes this?

PROLLY NOT!

what i think it is, is that the fluids in the trim itself are cold making it thicker so it takes longer to run through the system, once it warms up they are thinned out and run more fluidly throughout......this may sound stupid or i may be a jackass when it comes to this stuff but my motor has been doing it since i bought it brand new and the trim has never went out on me and this is the only explanation i could come up with.
