Another “is this reallly it!” question.

2019 Makai with 400

I have 3 blue plugs
1. Transmission
2. Directly under cylindrical heat exchanger
3. On a line near heat exchanger
Beyond the 3 plugs there is a hose near the transmission with a garden hose fitting that had to be disconnected.

I will loosen the cover for the raw water pump impeller, but change in the spring.

Am I missing anything? I boat only fresh water lakes so I am not taking any anodes out. BTW the plugs near the heat exchanger are quite a reach, how do you all do it? Lay on the motor like I did or do you take the side wall out?

I will change oil, trans, Vdrive fluids another day and replace impeller in the spring.

Anyone have part numbers for impeller? Also I have the g6 ballast system, thinking about changing those impellers in the spring - anyone have a part number for those?

Thanks in advance!
