There are supposed to be two white plastic water tube guides in there that make installation much easier, along with confirmation of proper water tube alignment/insertion. They are usually stuck on the copper water tubes when you pull the gearcase down…The plastic water tube guides are not the same length, intentionally. This way, you can get one tube aligned, then slip the other one in place. And yes, trying to get this gearcase installed without a helper, is truly challenging.
Yes, accessing the thermostat is a pain on that engine, you have to remove that electrical bracket that houses the powerpack and electrical pieces. I too, would leave it alone, unless a cooling problem is detected.
