With a little help from a friend I learned that the fill / vent plug threads for the Bravo Drive are 3/8-16 which are tapped using a 8mm drill or 0.3149" dia. The Livorsi GSOT1/8 oil temp sensor is 0.321" dia. That is 0.006" diameter interference or 0.003" thickness/side so the probe should fit...tight but wit a little emery paper just right. The threaded shank of that sensor (1/8 NPTM) has a 0.25" unthreaded length and a 0.375 hex head height part of which could be machined away to provide the needed thread length. The only problem is that the 3/8-16 external threads root diameter is 0.2983" dia which would cut into the sensor probe by 0.0229" on the diameter or 0.0115" debth /thickness. I do not know what the sensor probe wall thickness is so that remains the question as to if it will work.

Something on the horizon guys...patience!!

Well as far as Gaffrig and Livorsi is concerned they no longer offer the noted sensor cable system. The individual (a one man operation) that used to make them and supplied both has gone on to his reward. So you have no competition that I can find.

It is forthcoming, prototype has come and a revised report has gone back to the manufacturer. A new prototype is due back post haste. Keep watching this post if you're interested in this product.

Any idea on price for the sensor?

Livorsi checked with their supplier for the GSOT1/8 oil temperature sensor per my question below regarding sensor body wall thickness. The supplier would not provide dimensions but did advise that there was sufficient sensor body thickness to allow cutting a 3/8-16 thread. Livorsi also advised that the sensor internals are completely potted so the unit is water proof as well. At $19 per sensor this is just too tempting to not give it a try. However I will not be drilling any holes in the transum just yet.

PS The Livorsi oil temp sensor for drive oil temp use idea is only plauseable for fresh water use because of the brass body and electrical termination configuration that will need to be sealed from the elements to maintain electrical continuity.

See attached picture. The lower sensor is the stock Livorsi GSOT1/8 oil temperature sensor with 1/8 NPTM threads. The lower sensor is the same sensor except with 3/8-16 straight threads applied with a simple thread die.

Next time I get to the lake I will try the threaded sensor in the Bravo dirve and see how it fits.
