MAC,<br />If you still need an infrared temp gun I have one you can borrow.<br /><br />ezeke is correct, listen to DH he's the man!<br /><br />ps <br />I am getting ready to put an 89 120 looper on the back of my 1974 17' Wellcraft, as soon as the transom repair is complete.

Thanks for the offer Tom .. BTW I work in Largo (well they say its Largo, but we call it Clearwater) .. I'll get the water pump kit and go from there..

Ok .. UPDATE...<br /><br />Found a local marine shop in Largo .. that so happens to be owned by a friend of mine! What luck! Anyway, bought the BRP waterpump complete kit.. installed it in less than 2 hours.. and yes, it has solved my overheating problem. <br /><br />Now I will do some additional experimenting with the speed issue. My buddy mentioned that it could be something as simply as the design of the hull .. meaning it really doesn't get totally on plane until I am in the 4000 RPM area.. <br /><br />I have also changed the two carberators that had different intermediate jets. The "book" calls for size 50, two carbs had 50, one had 47, and one had 40. So, I will test the boat maybe later today...<br /><br />Now for the NEW problem... the alterantor has stopped charging. I tried checking the yellow/gray wires to ground with an ohm meter.. but I am not sure I can check them accurately this way, since this motot seems to have an intregal rectifier/regulator. Any help would be appreciated!<br /><br />I DID chek the yellow pair of wires for the stator, and it seems to be what the book says (about .95 ohms)

Great! Thanks for the update.<br /><br />The yellow and yellow/gray wires coming into the rect./reg should have around 16 volts AC between them. If you have the 16 vac in, and all of the connections for the charging system are clean and tight, replace the rect/reg.
