Ayuh,..... They'll be in the top of the y-pipe,....

Which ones depends on which y-pipe ya got, 3" round, 4" round, or 4" oval,.....

I'll just take a look, It has 4" rubber hoses that go from the risers to the though hull outlets. They are probably 3 1/2 or thereabouts on the inside.

No thru-prop? External Salisbury flappers? 4 inch...
