98' GP800 Temp Sensor Question & Wave Eater Clip Check
Howdy, new to the Yamaha side of the site.
I just picked up a "new-to-me" 98 GP800. 114 Compression in both cylinders, 120 hours, engine compartment is a little dirty but the ski runs great. Piston wash looks beautiful.
Two quick questions:
Temp Sensor - I noticed it's currently installed in the head. There seems to be a port in the muffler too. A search shows photos with it installed in both places and I did notice this thread: http://www.greenhulk.net/forums/showthread.php?t=102814 Want to confirm that I should move it from the head to the muffler?
Wave Eater Clips - Owner didn't know if wave eater clips had been installed but he "thought so". From what I've read, this is a must. And on the GP800 the entire exhaust has to come out to install them (meaning new exhaust gasket). Anyone have any luck checking one of the powervalves without removing the exhaust (I'm being cheap, I admit it). Is there something in there that needs to be removed prior to installing the clips, or just clip them on and go? Couplers necessary as well??
Thanks in advance!

I have read on this model the exhaust manifold MUST be removed to remove the PVs Just remove the exhaust, remove & clean PVs, install the clips, install everything in reverse.

I just rebuilt the same motor-same craft for a customer and it was in the exh pipe
also yes mani removal to get to the pv covers... requires a gasket because the factory one will come apart
