Congratulations! Happy to hear that you have several critical projects completed. Sometimes, if you don't have the time or expertise, it's more practical to outsource; I am sure that you learned something along the way!I actually paid someone today (and they showed up!) to route my depth finder wire, fix the hole I drilled incorrectly (for the depth finder going from captain's table to cockpit), and connect the antenna (with the existing wire, ) fix my propane solenoid, and fix my navigation light that was out. All in 3 hours of work. (I've spent what feels like decades trying to work through this...) Plus I did a radio check, it worked! I still have more projects, but these were the outstanding ones on my survey so today has been more than glorious!
With regards to the propane solenoid, I only leave the tank valve and solenoid on while actually using the stove/oven. I always turn off the tank valve off while on board overnite or when off the boat. I know some who rely on the solenoid only and always leave the tank valve open; I don't trust the system completely, so I just turn off the tank valve for ultimate safety precaution, maybe overkill, but.....
Good luck with the upcoming projects....there will always be projects. I complete one and add two or three, have never been project free!!
