Optimax service recommendations - please
2003 250XS Optimax-
Service recommendations? So far I have the basics: Water pump Gear lube Fuel filters Grease Then a few more things: New Compressor/Alternator Belt Clean anything that needs cleaning Then, Checking the little screen on the water line going to the compressor for debris? I figured on checking all connectors for corrosion and give it a good looking over. What am I missing? Ferm,Spare,Skools, Capt. Pete? Anyone else?

Good info, Thanks Phatdaddy. I forget T-stats.
That is a big one right there. It looks like the fuel rail comes off to do those on this one. Damn. It shall be done. Poppet, I have done two on Opti's now. I waited until the diaphram bit the dust and flooded the cowl with salty H2O on the first one.. Second one was done as a preventative measure. Anyone else, I certainly didn't mean to limit the field on this inquiry. I know there are some brilliant folks here beyond those mentioned. LOL Thanks in advance..

If you wanna go all out you could send the injectors(all 12) out to BROCATO for cleaning and flow testing. And not sure on the OPTI, but I know on most dry throttle bodies you should clean it out as well as the IAC every so often.

Motor is still running like a top. Injectors, air/fuel, that would be a winter job. This thing has IAC? I bet you are correct about the dry intake with reeds it will be gummy on the backside of the throttle plate. I will look into it. I have been hesitating to do anything except put fuel and oil to her. I hear the TPS is a joke and cannot/will not take even so much as a drop of water.
Scallop season is on us, vacation too, don't want to get too involved. Can't afford the down time. I was thinking of pulling the VST for a good cleaning and do a decarb. Still running ringfree, and 93 or 91 recreation.. Thanks again

just do the basics, put a new water pump in it(mercury brand only), make sure the oil line to the compressor is clear. I'd look hard at the VST unless you knew wildman was already in there. Look at the thermostats and keep on running it.
