It was a terrific opening half for Kenya who pumped in five goals without reply against the Indian Ocean Islanders.
Rambok Ogam grabbed a brace, first finding the back of the net seven minutes into the contest, before he was back on the scoresheet seven minutes before halftime.
That sandwiched Collins Sichenje's headed effort in the 35th minute as the Harambee Stars commanded play.
Skipper Michael Olunga made it a four-goal advantage from the penalty spot in the first half's stoppage time to throw the game beyond Seychelles' reach.
Olunga sealed his double in the 67th minute when he headed in a Rooney Onyango delivery from the right side.
The afternoon ended on a bright 5-0 note for Kenya and Olunga who was being linked with a move to Kaizer Chiefs during this transfer window.
