Hi Harmonie,
I am probably going to have to add overcurrent protection to get new insurance.  The only Blue Sea Terminal Fuse blocks I see are maximum 300 Amps.  Someone said the bow thruster can draw as much as 400 amps or more.  I also see that you installed fuses on each pair of batteries in your house bank.  Can you tell me why you did this and what size fuses you used.  Do you have any pics of the installation?
Thanks,
Kent
