1999 Johnson 200 HP Just bought, seller said model is Looper. Seller was working on a problem when I arrived. Said it was fuel line problem. He had friend - retired marine mechanic working on it. Told him if problem fixed I would buy. Came back when he said it was fixed for sea trial. Boat ran perfect, so made deal. Came back next day to take it to the lift I rented. On way home @4000-4500 RPM, Check Engine light & beep came on so I stopped to idle, light & beep went off. Check Engine light, Low Oil light, No Oil light, Water Temperature light all in one gage. Started again to 4000, CE light & beep on again. Seller said very little gas in tank, so put 40 gal 90 Rec & filled oil tank. Same thing @4000...CE light & buzzer on. Motor runs great, no sputter, water stream out 3 feet, motor completely still, no shaking, no skip...nothing but CE light & beep. I called seller, said positive it was fuel line, but engine ran smooth as silk. I understand CE checks other than fuel line... maybe something in VRO. I spent all money for boat, so have to be fairly certain I know what the problem is when I hire local mechanic.
