PROBLEM TO BE SOLVED: To provide a failure prediction system for a small ship accurately predicting a failure by recognizing an operation device for each operator.SOLUTION: A failure prediction system: includes a plurality of small ships maneuvered by one of a plurality of operators, an electronic control units attached to outboard engines of the ships, and a computer; acquires an ID of an embarking person and the like by making access to the computer when the operator embarks on the own ship; acquires past maneuvering data on all ships by an acquired ID of the embarking person (S10, S12), acquires new maneuvering data on embarking person's own ship and merges it with the past maneuvering data as well as transmitting it to the computer (S14); sets a normal value range by selecting a prescribed parameter in combined data (S16); determines whether or not the parameter of the new maneuvering data is within a normal value range (S18); and predicts failure of an outboard engine of the own ship according to the result (S20, S22).SELECTED DRAWING: Figure 8 【課題】操縦者ごとの操作の装置を認識することで故障を精度良く予測するようにした小型船舶の故障予測システムを提供する。【解決手段】複数の操縦者のいずれかによって操縦される複数艘の小型船舶と、それらの船外機に装着される電子制御ユニットとコンピュータを備えると共に、操縦者が自船に乗船するとき、コンピュータにアクセスして乗船者のＩＤなどを取得すると共に、取得された乗船者のＩＤの全ての船舶における過去の操縦データを取得し（Ｓ１０，Ｓ１２）、乗船者の自船における新たな操縦データを取得して過去の操縦データと併合すると共に、それをコンピュータに送信し（Ｓ１４）、併合データの中の所定のパラメータを選択して正常値範囲を設定し（Ｓ１６）、新たな操縦データのパラメータが正常値範囲内にあるか否か判断し（Ｓ１８）、その結果によって自船の船外機の故障を予測する（Ｓ２０，Ｓ２２）。【選択図】図８
