I have been watching those Matt I like them but IMO they don't look all that great. Have you seen one in person?

How long do you hold WOT on your 787? Discussion with temperature data included.

No I have not. I like the way the screen turns red on these new ones when they hit your preset max temp though.
Just wait for a deal on a Avenger 1 or 2 or a Hottach 2 or 3 if you want to kick it old school. They are no longer being supported though so when they're broke they're broke. They don't like water either. I brought one back once with the put it in a bag of rice trick.

I had one of those snowmobile egt's by Koso. Those WERE expensive, but worked pretty well. I don't believe they'd be waterproof enough for X4 mounting though (I had mine in my Challenger). I wanted to find a hottach, but they're practically non-existent now, and the ones you do find are super expensive. I had to drill and tap my 787 manifold and used them for tuning and general monitoring. My temps were right around 1160 at WOT with stock everything. The damn gauge flew out of the boat when I forgot to secure it one fine day. Lost it forever. The thermocouples for these things are dirt cheap, but getting a pretty, waterproof display to read them is where the $$ comes in. I wanted to program an arduino to read the temps and maybe encase it in epoxy or something, but that project was harder than I thought and has been placed on the farthest back burner. I decided to just quit screwing around with 787's in the boat altogether. It wasn't enough power for that boat. Was loud, inefficient, always needed expensive oil and rave valves, and blew up once a year. I got fed up and decided to stuff a 4tec in there. That project is going to happen this winter, after I get my car fixed up. Already acquired and rebuilt a motor from an 03 GTX S/C. I think my fuel consumption will remain the same, but I'll go 10mph faster, run quieter, smoother and be able to rely on it more. Might even take the backup trolling motor out of the ski locker.
You guys are right to be worried about your temps. I believe that is one attributing reason to my recent crank fail on my SPX. Suspected culprit: a clogged drain line (the one that leads from the back of the cylinders). I must have been riding around like that for a long time, because there was a good 7-8" of sand built up in there. It's easy to overlook, and the only way to really test is to pull it off the exhaust elbow and blow into it (unless yours is still clear). In any case, you probably won't see the clog as that hose runs all the way back behind the battery. Check it before it's too late. It won't cost you any more than 10 minutes of your time.

I decided to use the on the head measurement over the water temp measurement since it would be less dependent on the inlet water temp. I have heard that since the water is only in the engine for such a small amount of time the temp change is very small.

Hey Rosie, I saw you had your boat up and running. Wanted to know if you ended up picking up one of these sensors and if you could add some of your data to the thread.
Bump.
