Port Side Bennett Tab Troubles
 

Installed the batteries last night, hooked the hose up fired the engines up for the first time, turned right over. Outdrives moved fine, Starboard trim tab worked fine, check the port side. Nothing! I hear one click when I hit the down button, but that's it. Hear it bubbling when I hit the up tab, thinking maybe it's the celinoid or wiring. Gonna look into it more on Saturday, but anyone experience anything like this before with their bennett's. The boat is an 02 292 Fastech.

This may help. It give some pretty good tips on troubleshooting.

their tech support and customer service is excellent too

on my 1988 I blew out a cylinder and i think they sent me a new one free.
