Hope someone can help. I have a 90 hp 6 cyl. 1986 outboard that keeps stalling when trying to pull someone up on skies or under heavier load. It also when cruising will stutter and lose power for a brief second then come right back up to power. I've had the jetting checked and changed on all three carbs but that seems to have only made things worse.

You need to find out what is really wrong.Add yours to the long list of "i fixed /cleaned/adjusted /replaced the carburetors but it still runs the same.Check fuel supply and check wiring (shorted plug wires) either to the block or cover.There is more to check.
