Carrier part number for 115 4 cyl 2 Stroke

[SLOWER]

This year I would like to replace my carrier while I do the water pump. According to the diagram the part is 43040A1. Is this in fact a two piece part?

Will the water pump kit 817275A2 and that carrier part be all the pieces I need for a complete replacement?

Thank you.

Two pieces do come with 43040A1
If want complete water pump kit order 43024A7.
