    1987 Wellcraft carb size?

    I have a 1987 wellcraft and the carb was replaced with a 600 cfm edelbrock marine carb, the boat idles and acclerates fine until 2500 to 3000 rpm but wont plane out or accelarate beyond that. Is the carb big enough?

    1980 Black Max no spark on #1 and #2 cylinders

    I have a 1980 blackmax 175 and I'm not getting any spark on #1 and #2 cylinders. Switch boxes are new, compression is 120# on all cylinders, sparkplugs are new. Can I test the coils?

    1985 Johnson 175 Lean Idle Sneeze Re-Visited

    First of all thanks Gary H NC for some good advice on my lean idle sneeze. I used toothpicks while the motor was running and carefully blocked the lean idle jets and discovered its only the top carb causing the problem. My jets are #33 which is standard. How small should I go on replacement jets ?

    I've got a 1985 Johnson 175 with type III carbs and I'm experiencing a low speed hiccup. I've deduced from searching the forum its a lean idle problem.

    What is the proper way to cold start a 1985 Johnson 175?

    As the title states I would love to know the best way to start my 1985 Johnson VRO 175 when it is cold. I have replaced the carbs and primer solenoid and the motor runs great but I think I may be depressing the key switch too long or maybe not long enough when I start it after it sits a few days.

    I have a 1985 Johnson 175 with the VRO pump on it which recently died. The previous owner by passed the oil resevoir and was pre mixing the gas and fuel as was I, now that the VRO pump is dead can I simply put a standard pump on it? If so what year and make would have the proper pump to install?
