Okay, I don't do well in this heat and humidity.
Decided to replace Helm mounted Lowrance Hook2 - 7 that came original on the boat.
It was a royal pain to pull the old transducer cable.
Being part of the original build, the original cable was wrapped around everything.
I had to remove the Helm from the deck, as the holes being off center I could not get the connector through the hole, nor pull the new connector back through.
Then being bolted and least there was slots in the mounting bolts, so you could hold the bolt while tightening the nut. Still a pain with all the wiring under the dash.
Needless to say it was one heck of a job that took a long time to complete.
Taking the boat to my son's house so he can fit the new FF to the dash. He has much better skill at that type of wok than I do.
