SIM has great parts diagrams, Just keep the pre-mix and enjoy.
What, if anything, does this have to do with the OP's question?

Just wondering.

Because the OP said "I know his Grady was a 1999, I recall him talking about the motor being a year or two newer few times." 1999 + 2 + 2001.

And it is a great way to attract keyboard cowboys...you can stop wondering

What are we wondering about? It's been at least 7 years since I had any conversation with him about the boat, motor or any dates. All in casual conversation. I was simply trying to find some information on the motor. I can do the work to bring her up to speed myself once I have the year and model. Did I step on someone's toes?

Better get back on you meds..... nothing to wonder about. The OX66 from 1999 to 2005 are all basically the same.....And 20 years later they are still running....

Here is my plans being I have ok compression and she fired up. Drop and inspect lower unit with new impeller kit.

Replace anodes

New plugs already in

Replaced thermostats and popit value

Pull and send off injectors for rebuild.

Rebuild fuel pumps

Clean and or replace O2 sensor

Replace fuel lines and other hoses that I can

Clean electrical connectionsI may clean water passage ways on head depending on how it looks after new impeller is installed. Then I will run it till it dies. Good motors so I believe it’s worth the time and money compared to a new one.
I'm easy on my motors so it should last. If not I may rebuild the powerhead and ride some more. Cant afford new due to re powering my Key West 2 years ago with a new Zuke 140.
Thanks for all the help. Time to go to work.

I’m out
