What Tools Needed to Maintain Rotax 155hp on 2012 Sea-Doo Challenger

About to pull the trigger on a 2012 Sea-Doo Challenger twin 155hp.

What tools would I need to work on the engine and/or impeller? For example, to pull the impeller for cleaning or wear ring replacement, engine maintenance (plugs, etc.), and so on?

I have heard tools needed are all metric, and to have plenty of 10mm sockets and wrenches (I guess for "in-water" work). Is there a list of sizes and types (sockets and wrenches) that I would want to have on hand?
