The iboats forum moderators are excited to announce that at this time it appears the iboats forums posting pictures function is working once again. Though we cannot promise for how long, we're hoping for indefinitely.
If your hydraulic actuator looks like the one in the picture below you can go http://www.cook-mfg.net/ and download a an owners manual. There is trouble shooting information in the manual that might help you figure out what is wrong with your unit.
If you need parts to fix yours or end up replacing the unit PM me, I can help.
