Looking for some assistance, my 2013 Lagoon
450 has sat at a marina in Langkawi since the end of Feb 18. It has a Coppercoat treatment to the underside and I have a diver clean it between haulouts. There was a gap between cleaning
reasons by guy who overlooks my boat) on April clean nothing noted by diver, when cleaned in late September, diver said some corrosion
, sounded like anode ring needed replacement, asked local shipyard boss to have a look and he reported that legs were gone, and two complete new saildrives required. ( I was in Australia
trying to work
out what extent of damage was by phone
with language barrirers) The boat
was towed to the shipyard and the ‘dissolved’ saildrives were replaced. The battery
isolator has been identified as damaged, probably due to a lightning
strike, several boats in the marina suffered damage a few months ago, the dehumidifier timer stopped working about the same time?? The aircon sea water pump
also caught fire when started, there is no blockage in the feed lines??
The 200 hour SD50
saildrives are now replaced with new SD 60 saildrives, it was in the slings of the straddle carrier/ lift
yesterday when we tested everything was working and no leaks
around new installation
before leaving the shipyard. We noticed the house batteries
were discharging 20A +/- with all switches off. We inspected that pumps in both bilges and non were operating. I instructed shipyard to put boat
back on hard to find stray current
The legs removed were in such a bad way, long term industry persons have never seen anything like it.
The shipyard is waiting for a specialist electrician to come to try and find isssue
Has anyone got any ideas where to look?
isolator is due to arrive soon to be replaced, boatyard does not believe this is the problem, just does not allow various charging
sources to be directed, example, port engine
will only charge port engine
battery only, gen set will only charge house batteries
I am anxious to find the issue, time is running out for the planned holiday, and
I cannot drop boat back in the water
until issue resolved ( I do not want to be replacing two more saildrives) and except for the shipyard there are no facilities to haul out
7.87m beam cats here, and cannot hardstand
store long term as commercial
shipyard does not have available room.
