Welcome to the fold! I too have the 87 C/C, with a 225 Yamaha on it. I have had to clean up some of the wiring from time to time mainly due to corrosion issues and general maintenance. The wiring from the manufacturer is still going strong and I have even found some additional wiring to allow for upgrades. (Extra fishwell pump was allready wired!) There is a wiring tube that runs under the deck on the starboard side, when you make use of this leave a rope or cord in it to plan for future pulls of wire through this area. If you have any needs that I can help with I'll be glad to help all that I can!!
