MY OBSESSION

I AM RUNNING A 25' OBSESSION CAT WITH A 525SC. A FRIEND TOLD ME THAT I SHOULD INSTALL A PYROMETER WITH A SUPERCHARGED ENGINE. CAN ANYONE TELL ME IF I NEED ONE, AND IF I DO SHOULD I HAVE THE SENSOR/PROBE PROFESSIONALLY INSTALLED???

Yes it comes in handy we do it on alot of boats but its not mandatory,for sure .
But if you chose to use one do get it welded in by a good welder
but other than that its easy to install

WTF is a pyrometer???

Pyrometer = exhaust gas temperature meter. Used to dial in air fuel ratio.

Its the most important guage on my console. Tells you alot about whats going on inside. It does require drilling of the exhaust manifold. Best to have a bung welded on too.

I have 4 of them on my boat ! 1 for each side of each motor ...... great to have ! IF it gets hot you know something is wrong before you blow it up !

I shouldn't brag ....... Mine came that way ! It has spacers between the heads and exhausts that have threaded ports to screw the probes into . They read a touch hot there as you are in the direct heat of the flame but they get the point across . Idealy you should be about 3-4 inches outside the port in the ehaust tube .

Best thing I EVER put on my Skater. Like was said earlier, it really gives you an accurate depiction of what is going on inside. A few things to remember. Accurate placement is of paramount importance for proper reading. Secondly, install one probe for each bank if possible, then you know what each side of the motor is doing. Lastly, DO NOT cut the wires and READ THE DIRECTIONS READ THE DIRECTIONS READ THE DIRECTIONS! You will not regret having them. Good luck.

I was looking at a boat yesterday that had pyrometers. When I asked questions, the mechanic also talked about oxygen meters or something like that. What are they, where do they mount and where do you buy them? Thanks for the help!
