When it was first published in 1990, the Boatowner's Mechanical Electrical Manual broke new ground. It was hailed as the first truly DIY manual for boatowners and has sold in its thousands ever since.There have been significant changes in boat systems since then, particularly electrical systems, and this third edition has been fully updated to reflect these developments and expand its predecessor's worldwide popularity.
