My 450 made a trip to the yard to have the stick pulled and inspected along with a bottom job. Uh Oh! when set down on the blocks water squeezes out and I get an estimate of $2500-$3000 to pull the keel and reseat...crap , but gotta be done. Overrun on estimate with never a word spoken $7000! Estimates on boats mean nothing in Fl. Okay that is really really bad then it gets worse. Starter won't turn, boat yard plays around and puts a charger on it, writes bill for $300. After the boat is put in a slip I find that my Bus 1 has no AC to any outlet, the batteries are trashed and all the electronics appear dead. Boat yard wants $500 for it being in a slip, no extra charge for the sand and dirt as well as extensive coverage of pine needles. Got starter working and moved boat out of there. Survey of electrical and electronics damage in excess of $26,000, and that brings me to the point of entering this thread. I am looking at replacing all the original Raymarine with new as insurance is supposedly covering all but the deductible listing it as lightning although there were no reported strikes and no other boats were damaged. I am looking at the E7D radar package and E7 MFD, EV-400 Sail system, I70 displays and new wind system, 6 Crown CR-235 GC Batts to replace the Deka 8Ds etc.. I have been trying to determine if I can use the Simrad DU-120 drive unit on the EV-400 system or not. I expect that the circuit interconnect diagram will be woefully insufficient to cover as previously stated in the thread the nickel and dime approach to connections and cabling. It also would seem to be of benefit to have a package and single manufacturer approach to smooth protocol communication. Until I get the insurance check in hand I will only do the battery replacement and everything else is on the table. I could not get to the Miami show although I think it would have answered a lot of questions. Ideas and opinions would be well received! I will certainly know this boat quite well when done as I had everything on board working perfectly except for a single power panel meter select switch after owning it for two months before it made the yard trip.
