The reported issues with the Mercaha 90 had to do with the carburetors installed by Mercury on the Yamaha powerhead.

Some of the carburetor passages were small and prone to clogging when the boat was infrequently used. Some owners had issues with clogging/bogging down.

Owners reported by adding the Mercury product QuikKleen eliminated the issues completely.
