Tempature sending units

[bloodclot]

Hi all,<br /><br />Kinda a newbie here and have some questions.<br /><br />I got twin 1985 200hp rudes, the tempature sending units for the motors adjust by screwing them in till they just touch the head correct?<br />And should the paint be removed for a more acurate reading where they contact?<br />And how much should I tighten them after initial contact?<br /><br />I know the gauges work grounded them all out and they pinned to max.<br /><br />any input would be greatly appreciated<br />thanks in advance.

O-K,<br />I had to read your question a coupla times but the answer is yes, the sending units should make good, solid contact with the head(s)and the paint should be removed. I doubt if the screw is an adjustment, it's just to insure the sensor is in good contacy with the head.<br /><br />c/6<br /><br />Hooty

Frankie-100***x once made a good suggestion to use heat sink / thermal grease to make a good thermal connection between the sending unit and the engine block. It's available at Radio Shack in tubes, or you should be able to get a dab of it from a friendly computer shop.
