Not sure if this is your engine but if so it says 29 ft lbs. This is from SBT though and shows no sequence so take it for what it’s worth. https://www.shopsbt.com/pdfs/y11001200npv.pdf

Might be worth buying a shop service manual.

Is this what you seek? Off a manual for another boat with hopefully the same manifold.
