You and Tom got them.  I'll mail them on Monday.    I may make a few more if there are others who want them.

Thank You bizler, do you have a picture of where you have them mounted? How much slack was left over of the extension cable?

The sensors come with a 21" cable having a connector about mid way.  The extension cable is 72" long.  There is plenty of slack in the length. I used a half dozen tie-wraps to secure it to the other cables going into the engine compartment. This works out very well because it places one connector in the engine compartment were it can be easily uncoupled when you remove the motor.  So once the thermistor is installed you can just leave it alone.  Obviously, the sensor adaptor goes in the unused dipstick hole.  I found it necessary to temporarily move the floatations tank forward in order to be able to "fish" the connector along the other cables.

I applied a bit of Permatex to the thermistor threads when I installed it in the adaptor just to assure it stays put.  The instructions suggest using silicone sealant. I used a needle-nose pliers to tighten the thermistor against its own gasket in the adaptor. There isn't much room for any kind of wrench in the recess I provided.

Trail Tech doesn't provide any sort of strain relief on the connector wires so I wrapped them wit electrical tape for good measure.  I also dulled up the catch on the connector in the engine compartment to make it a little easier to disconnect.  Otherwise it's a bit tough to unplug it.

Do you have a picture of where it is located on your boat? They offer several lengths, we have 12", 24" 48" and 72" extensions available.

You will need the 72" extension.  It will be a little long but 48" won't make it.   Here are a couple of photos showing the connector and the sensor adapter with the probe installed in the engine.  The gage itself I installed on my little dashboard as seen in the preceding photos above.  The wire merely follows the other wires and cables past the floatation tank from the gage to the engine.

Looks good! I'll order the 72" extension then. EBay has both at the same supplier with free shipping. Thanks

I mailed an adapter for you along with 2 additional to Tom today.  It should be there in a few days.

Thanks again to Bill For outfitting me with machined connection.  We are so fortunate to have so many forum members with all sorts of skill sets that are so willing to help.

Got my vintage 2006 out on our California Delta today and my data points would be:  4400 Rpm 198 F; 2500 rpm 150 F; 1500 rpm 125 F.

My engine is a new ex21 with 17 head and Amosol oil.

Tight lines, John

That's great John, I've been waiting to hear how that motor performed for you! Your oil temps are a good indicator in my opinion of how much the water cooled muffler makes a difference, no doubt Amsoil made a difference too... love that stuff.  \./8

You are welcome...  Those temperatures are quite low compared to my experience.  Maybe the Amosol oil is the key.  Tom is doing a couple so it will be interesting to see his results.  If the look close to yours I may be switching to synthetic also.  Thanks

I was out testing a boat today, EX17 head, water cooled muffler, Mobil 1 synthetic. Tach showed 4260 rpm, held 4180-4200 for the 5 miles I went up river. Oil temp after that run was 276f, motor was at full throttle the whole time.  Coming back down it stayed around 260-265f. Definitely the high side of the spectrum, would not want to go over 300f and definitely would not recommend conventional oil in these now. Oil should be more than 220f to prevent moisture buildup though, it can be too cool.

Yes, your oil temps are close to what my Dakota Digital gauge indicates. I now know when to throttle back, how far to throttle down, and what is an acceptable upper cruise speed limit.
I was going out to test my new cam & ducting this week after finishing chores when I turned an ankle coming off a duh, ladder.. Now rain till Sunday.
