Bolt size on 1990 Force 90HP outboard air intake unit.

The six (6) bolts on the air intake? above the carburetors are missing on my motor. Does anyone know what size those should be? Also, how important is that part of the engine and does it have anything to do with grounding the electrical?

If you are talking about item numbers 66 & 68 holding on item #69 then you need 1/4 - 20 X 1-1/4 and 1/4 - 20 X 1-3/4.
