While doing monday checks on the parker,I found that the starboard tab would not operate. Port side is O.K. I figure it is either the switch or the actuator ,I'll switch leads to determine if it is the switch.I think it may be the actuator because of rust around the base near the tab coming from the stainless ram. If the actuator needs replacing is it possible with out having to fish new wires thru the transom up to the console. Noticed that the top of the actuator has a couple acorn nuts on top , can it be rewired with the old cable?
