Drilling out restrictor in pump?
What is the easiest way to drill out the yellow water inlet restrictor?
Drill from the inside or take the pump off and do it from the outside?
Could I just take it out, or do I have to drill it out?

bro You seem to be making it harder than it seems... the washer pops right out.... then secure it the best way you can and drill it out.. to the right size.

Sorry if I sound ignorant but what is the purpose of doing this?

More water pressure/ flow.
The x skis come with 1 mm larger due to the water routing.
On 215 skis the water is pump-ic-exhaust.
On 255 skis the water is pump- T fitting - one to ic and one to exhaust.

I drilled my washer out to 9.5 mm as I am running heat exchanger and wanted good flow.
So far the xs core is holding up.
I'm running everying in line (pump-ic-hx- exhaust) but going to change to T fitting this winter after the pump to run a bit cooler water to exhaust.
I know off topic but oh well.

Don't take it out or drill too big, you want some restriction. If you are having over heat issues at the waterbox you can drill out the three small holes on the j pipe one size bigger also. That seemed to fix my problem on shorty waterbox

I pulled the washer and the hole is about 7.5 or 8mm to start and I drilled it out to 9.5-9.7mm, I hope that will work,
