The actual install wasn't long, but a setback that required a separate trip was stainless steel bolts holding the outboard kicker motor throttle onto the boat must have had red LocTite because they had to be drilled out. Time passed and we forgot the bolt size so I sharpened up a few sizes of drills to bring and extras of each because it was for stainless. I also took a long time with the instructions, so my first time installing this was long.
But, should I ever install another, those times wouldn't exist. I grew up with boats and boating electronics, so I'm experienced with a lot of various boat work.
I also do something that takes a little additional time, but it's worth it on boats for long term reliability and particularly this one because it goes on long trips to Canada and out to sea and salt water is also a consideration.
I make all of my electrical connections impervious to salt water corrosion by soldering them. But, I'm good at that. It's usually not long.
But, I go for reliability rather than a best time.
Take trailer lights for example. Professional services often use "trailer wiring splice connectors" (search term, link below) that quickly and simply squeeze on with pliers. The installer looks good and did it in good time, but troubles come later. As corrosion occurs, frustrating and hard to find intermittent trailer light issues will take much more time than saved with quick splices. Besides, you don't want to be repairing things while on a fishing trip. I don't use those. I solder all connections.
On installing new power outlets for outriggers, I had to clean black oxidation off of the multi stranded copper wires and solder them because this boat gets into salt water environments. Then I filled the outlets with dielectric grease.
