To provide an intake manifold capable of reducing passage resistance while securing pressure resistance and mechanical strength, and an outboard motor capable of being miniaturized in a width direction and thinned by virtue of the intake manifold.SOLUTION: A resin intake manifold applied to an engine of an outboard motor includes: a surge tank T having a flat contour and including an intake air introduction port 21c; and a plurality of branch pipes P1, P2, P3, P4 defining intake passages p1, p2, p3, p4 communicating to an internal space S of the surge tank. A contour wall 11 of the surge tank T includes a plurality of projecting portions 13a, 13b, 13c projecting toward the internal space S and directed toward an intake passage side.SELECTED DRAWING: Figure 6

    【課題】耐圧強度、機械的強度等を確保して、通路抵抗も低減できる吸気マニホールド及びそれにより幅方向の小型化、薄型化が図れる船外機を提供する。【解決手段】船外機のエンジンに適用される樹脂製の吸気マニホールドにおいて、扁平な輪郭をなすと共に吸気導入口21cを含むサージタンクTと、サージタンクの内部空間Sに連通する吸気通路p1,p2,p3,p4を画定する複数の分岐管P1,P2,P3,P4を備え、サージタンクTの輪郭壁11は、内部空間Sに向けて突出すると共に吸気通路側に向けて方向付けされた複数の突条部13a,13b,13cを含む。【選択図】図6
