I have given up on the standard waeco unit which is unable to lower ambient temp more than 8 degrees (in the med) and adding insulation made no difference, so its time to replace with a frigoboat system. Only problem is I am not on the boat to check size of the box for new evaporator. I have an ocean 47 but it may be the b 47 has the same box. If so would someone be so kind and give me the dimensions of the box - particularly the side ( hull side, and return - height and depth. The proposed plate would be 600mm long by 210mm high. It may need bending if it is too long to fit across side -in which case I need to know where to bend the plate and position for the pipes.
