I just purchased an 18 ft fish and Ski with a 150 merc. and there is no temp gauge. I realize there is a temp warning beep, but is the damage done once the temp beep occurs?? Also is there an opinion on having a water pressure gauge. I guess i'm just taken by suprise - though it should have temp as a minimum. I just sold a bass boat with full gauges (Temp, trim, W - Pressure).<br /><br />Any opinion welcome.<br /><br />SMurphy
