We had a 44 Sea Ray come in that had been built for and used in Singapore. The owner want us to convert the boat to US power since it will stay here. I have not been able to inspect the boat myself yet but I expect to find a 220volt 50z set up. I am thinking that a speed/governor reset on the generator should bring it up to 60hz and the rest of the job will entail swapping out equipment and outlets. However, if the electrical outlets are are 220 I will probably have to do some reconfiguring on the panel to get them on 110. TV's will all have to be replaced etc due to transmission standards and voltage. I would think that stove burners and water heater would be ok as is. I would have to see if the A/C units will operate on 50 or 60hz or if they will need to be replaced. Battery chargers too. etc. etc. Electrical outlets will all need to be changed. I will know more once I take a look at the boat and the existing panel. I would also plan on keeping as many items 220v as possible for efficiency. That boat could probably run on one 50amp 220 cord but might be better off with one 50/220 and one 50/110 as I have seen on other larger Sea Rays in the area. I know there are transformers available to make the whole boat convert but they sound expensive and it sounds like the boat will now remain in the US. I know there are several guys on this list who have probably done this conversion before. Is there anything special I am missing here or need to consider? I have taken a 110volt boat and converted it to a split 100/220 system with a new panel etc and did not have any issues. It seems like this should be pretty straightforward. Thank you in advance for any EXPERIENCED advice.
