Thank you! I've been tearing my hair out and darn near blew up my (new to me project) boat with the flooding caused by a new fuel pump w/o the spacer. Now I know what the issue is! Would have been nice if this was more widely known and/or actually shown in the Mercruiser manua.
Latest "Project" is a 1998 Caravelle Fish n Ski. Basic boat wiring is a snap, but I have no clue as to how to wire up the trolling motor / live well pump / 12v/24v control panel ... anyone out there able to help...please...
