Previous owner used TCW3 oil. I’m wanting to switch back to SeaDoo full synthetic.
What is correct steps to switch back.

Drain the oil tanks and clean them out with solvent.
Install a new white inline oil filter.
Bleed the oil pump.

It is also a great time to replace the little 3/32" oil lines from the pumps to the intake manifold as that is the only typical point of failure on the oil injection system.

I’m hearing remove, drain, and clean out tanks with solvent then reinstall tanks?
I can’t imagine just drawing out the old oil with a vacuum pump, swishing around solvent then vacuuming out the solvent…..that be too easy…

No, you want all the old oil out and no solvent getting into the system.
Pull the tanks and do it correctly. It is also a good time to replace the rubber tank grommets that are prone to leaking.
