I've got a decent running Johnson Sea Horse Model TN-??, 5.0 O.B.C..<br />Anyway the engine runs after getting the Rich/Lean and choke in the right positions. <br />The problem is when I engage the forward only gear lever. Drags engine down and it sputters then dies.<br />I inherited the motor...
Is there a troubleshooting method for a 40hp, Mercury. It's a 1978 402 model 40 HP <br />2 cylinder S/N 5042254. <br />The problem is no fire to plugs! <br />I've been told it's either the power pack <br />#3324911 or the individual coils. <br />Is there a way to test the power pack? <br />Say...
