    Default "Hi everyone, We recently got

    "Hi everyone, We recently got a used boat with a '96 Johnson 90 HP engine. Took it out 2x , ran fine.

    My son took it out yesterday and put 1 pt of oil for about 10 gallons of gas- Ooops.
    When he was out the engine cut out but would always start right up again. It would idle fine but would cut out if he accelerated too much. He also said the primer ball was collapsed like someone was squeezing it.

    So, could some damage have been done to the engine in 45 minutes with that ratio? Also could the gas/bulb issue be the problem?

    Thanks for any and all help- I am out of town until the weekend so I can't check anything out until then."

    Correct the ratio and you should be fine. Usually the bulb collapes like that because someone didn't open the tank vent. If you have a built in tank check the vent for obstructions.

    A manual is a cheap investment.

    We are using an 11 gallon plastic tank that the prev owner said he got at Walmart. It does have an inline filter and my boy said that it was clear of debris and full of gas.
