This boat and motor are new to us. '92 Bayliner Trophy with '92 Merc. Black Max 150 O/B. From the time you start a cold motor till it pumps out a steady stream of cooling water is about 2-3 minutes. There is a slight spray when initially started but the steady spray takes 2-3 minutes. Is this normal for this motor? <br /><br />Is there a way to hook up a temp guage to this motor? There is no reference to this in the operations guide. Alarms are ok but a guage is the only way to go.<br /><br />Thank you for the help.
