G'day all. Recently, we put a second hand 225 Honda on our boat. (Cannot believe how quiet it is after the Optimax!!) We don''t have temperature gauges on the Honda, just the warning buzzer. I like to see what's actually happening temperature wise so was wondering if anyone had taken the lead for a gauge off the sender unit. I'd like to still have the warning bizzer in place. Comments or thoughts appreciated. Thanks, John.
