Hello All; I bought a new 2014 wake 155 last year, and noticed the vts did not work , adjusting up or down made no difference in speed or position in the water. ( the display does show the trim changing though ). This spring I tried it again and found the same results. I then took it out of the water, started it, and watched the back end while the trim button was being adjusted. Again the display showed the trim changing but the jet did not move. Still not working. Took it to the dealer and explained what was going on, he took it in the shop for a look while I waited. 5 minutes later he called me into the shop and said it was working just fine, and he had made no repairs. He started it up and gave it a little gas then started moving the trim up and down while I watched, he was right, it was working. I asked if it might have been a loose connection in the wiring that he might have bumped. He said all he did was take the seat off and shine a light back at the motor. So I'm at a loss as to what was going on. I haven't got it back in the water since I was at the shop, but hope to try it this weekend. Is it possible that the trim makes very little difference in performance??? Has anyone had a similar experience?
