Purchased used 2000 Dauntless 16 with 2000 90 Hp Merc. On first time out, noticed that temperature gauge did not register at all. Dealer claims that this merc runs cool and this is normal. Also when motor is tilted up I have noticed a slight oil drip in motor well. Has any body encountered similar problems? |

Bob, I had this same gage-reading-low-or-not-at-all problem with my Montauk/50 four stroke rig. It seems that BW is installing the 100-240 degree gage (Teleflex p/n 859684-1)in all the boats. This gage is scaled for the V-6 outboards and all inboard/sterndrives. I complained to my dealer and they installed a 60-200 degree gage (Mercury p/n 79-859685A1) which now at least registers one pointer's width beyond the 100 degree increment. |

Guys I personally have never seen a temp guage work "well" on an O/B. I would replace it with a water pressure guage. No pressure , higher temp. You can also tell why your buzzer went off(my temp guage)and if you have grass or water pump is getting lazy, etc. |

I have used the Temp gauges (Cylinder head temperature - not cooling water temp) on my Merc 200's for 12 years. Wouldn't be without them. Work just fine for me. For larger Mercurys, I think these are mandatory installations, and should not be replaced. I also use the water pressure gauges to compliment the temp gauges. |

Ditto Larry and Bisgshot on the pressure gauge. Installed correctly they give you instant feedback on the cooling system. I like having both a temp gauge and a pressure gauge, and on my 4-stroke motor an oil pressure gauge as well. Idiot lights and beepers only deploy after a fault occurs, and that may be to late. Gauges give feeback all the time. Sean |

I am glad they have worked for you guys. Maybe OMC never perfected it well enough. The buzzer like you said is a failsafe(if it works)and most are set at 180-190 degrees so you are still in the green by a good margin. Just like hour meters, I love water pressure guages which my 1980 merc came with, all motors should. |
