Which carbs supply which cylinders?

[bluebackfisher]

I Have a 1992 Force 150 hp outboard and it has 3 carbs and 5 cylinders. Could someone tell me which carb supplies which cylinder or cylinders?

Top carb supplies the top 2, 1&2
Middle carb supplies the next 2 3&4
Bottom carb supplies the bottom One #5

Thanks for the reply! Do you sometimes adjust each carb with its own setting in order to get the motor to run the best, or should all carbs be adjusted the same?

The initial setting is 1 1/2 turn out.
Then they get adjusted running at idle in the water, in gear.
I thought the top carb fed #1 and #2
The middle carb(little one) fed #3
The bottom fed #4/5?????

I though that was a 125 block with an extra cylinder on the bottom.

Nope they redesigned the intake and added a middle cylinder.
That motor was said to be the best HP. to Weight of any outboard.
The ones I worked on were pretty strong.

Not sure about the redesign but anyways. That motor was never 150 hp on its best day. MAYBE 130 at the prop but any modern 150 would smoke it.

Those motors were powerhead rated at a time when every other motor was prop rated. Did you know the 125 force was 107 at the prop.
