If you want them buy the boat with them already on it if you want them even if they all dont work...You will go broke trying to install all thease goodies yourself...People forget that the associated cost of the install is sometimes more then the unit being installed..
From modifying cabinet and trim to electrical , plumbing and thru hulls..etc
Many of theas systems are installed during initial boat construction and running cooling
lines additional electrical feeds and reconfiguring cabinetry is very expensive and time consuming issues..Most will be, "like plumbed" with a replacement model if nonrepairable and switching out there of more readily..
Case in piont...cost of Bow thruster 3500.00... cost to install in my boat... an additional 11,000.00...It didnt happen...
