There was recently an article in Ripley's "Believe It or Don't" where someone "HAD" arrived at their boat and "DID" bring all of the supplies they needed for the job.
Believe It or Else.
Should do the job perfectly.
#16 would be adequate for the wire from the starter switch as it is only required to supply about 0.5A for the Cole Hersey relay.

I have a boat with everything to fix it on board. It got nick named the floating tool box
Installing a relay is the best answer. BUT from the diagrams and images that I see no diodes are installed in parallel with the coil of the relay. This is required to kill the back EMF ( a high voltage that is developed when current is stopped through the coil by releasing the start button) to avoid damage to electronic devices. Connect the cathode to the positive terminal of relay coil and anode to the negative terminal.
in case you are not familiar with term "B+", it came from the tube type devices where tubes required A and B voltages to operate.
I have not heard of "B-" as this would mean a voltage below ground.

Yes, I see what you're saying about back EMF but looking my original wiring before the installation of the booster relay : The original #16 wiring to the starter relay did not have a diode in the circuit and this dates back to the original Hunter assembly. The starter relay coil which pulls 17.5A as seen on my Link 10 Battery Monitor during a "no start" episode must have a considerable back EMF when the flux collapses.
Maybe something to do with having the batteries in parallel in the circuit, absorbing EMF surges. Above my pay grade for now.
Ralph, here is a photo of 2 relays I installed near windlass motor to lower and raise the anchor with wired remote switches from the cockpit.
I included diodes in parallel with the coil, they are inside the blue shrinkage tubing.

Funny,
A friend of mine had a boat a lot of people called the floating fondue pot. Lots of good parties on that boat but it did weigh a bit much for the PHRF races.
