Here is a pic of the adapter I had made for my oil pumps. It can be modified any way you might want it. Like I said it can be made with a closed end and some kind of cap where the wires come out. Just need to figure out what thermistor and what kind of epoxy to use.. It can be made with a hex part on it also.

Let me know if this helps..

The stainless sensor body containing the thermister in the end would need to extend deeper than the threads and into the oil and away from the thread contact with the Bravo housing to get a more accurate reading of the oil temp rather than the case's. No reason to think the stainless body would not look essentially like the attached picture of the Gaffrig sensor. It would seem simpler to buy the Gaffrig sensor for $14 and have your guy cut the necessary threads on it. Probably cheaper as well but maybe not.

What size are the threads on that sensor 1/8" pipe? Is there enough meat on it to cut the proper threads?

yup ....1/8" .... wouldn't you need to drill and tap the existing plug?

FYI, there are 2 new Gaffrig Drive temp kits on ebay right now. Not mine and just thought I'd pass the info along.

If you tap the existing hole for the vent plug, it is too large I believe already.. and then you cant use a stock magnetic plug. you could drill a hole on the opposite side. But the upper should be dissasembled to do it.

No, I did not mean that. I mean thread the sensor with the same thread as the Bravo vent plug which is what I did to the Livorsi brass oil temperature sensor for the entire length of the sensor from the hex head to the end tip of the sensor (and cut down the sensors hex head to the same OD as the vent plug just far enough up the hex so it clears the recess in the Bravo drive housing ~ 1/3 the length of the hex head). It fits and works just fine.

See attched picture of the before and the after sensor threading to fit the Bravo drive I described (the hex cut down was done later and is not shown).

Hi all! Glad to see that this is getting some more attention. Rage that sensor you threaded down to the drive plug thread, does it seat in the drive properly so it won't leak? Looks good though. Hopefully the stainless one can be modified the same?

Hey Griff, thanks for pointing out the 2 set ups on ebay. I got them both. They must have been some old stock on that guys shelf since their no longer available. When I get them I will see what type senders they have and post some pics and info. Hopefully the kits are complete. At least the gauges are there and the shielded wires from the drive to the transom with thru hulls. Thanks for pointing them out.

I still want to figure this out and possibly get someone to market these again if we can simplify the parts needed. There must be a market for these. Really who would run without them? Let's keep this going, thanks to all.

Glad to help out.
