    Need Help!!!

    Hi All,

    We have a 4.6m Tinny with a 40hp 83 model Suzuki motor 2 stroke. No the problem is that when we first got it, it was great. We had for people in it and it jumped out of the water with no problems what so ever and cruised at about 40kph. Then we noticed that the head gasket was cracked and got a mobile marine mechanic out and no it is crap.
    After that we went to go fishing and got four people in it and we were sitting on about 22kph we don't understand. There isn't much weight difference between the people we had in it. As we were crusing along we were playing with the motor and they would touch some wire which would make the boat do about 30kph but it still doesn't seem right. It doesn't seem the motor is reving hard enough. It won't get on the plane now. And now we can't get the marine mechanic out. ANY IDEAS WE ARE STUCK

    Re: Need Help!!!

    Lets try and get the information cleared up so that we may try and resolve the problem. I am getting a bit confused.

    1. You had a mobile mechanic replace the head gasket.

    2. The motor would then not achieve the same speed.

    Q. How are you measuring the speed???

    3. By moving some wire you were able to make the speed go higher.

    Q. Is this wire associated with your speedometer or speed measuring device.

    Q. If not does the revs on the motor increase when you touch this wire you mention.

    Q. Does the motor run smoothly or does it sputter and miss.

        Crackerjack,
        Where are you? There are some very savvy outboard guys on the forum & often they will check out a motor for a member. Suggest that you do not run the motor until you determine what the problem is.
        ROLL TIDE, ROLL.................

        Regards,
        Peter

          Sorry if I am confusing
          Yes a mobile mechanic fixed the head gasket. When we next took it out it was running like it use. The motor runs smooth no missing or sputtering. We are using a gps to determine the speed. When we touched the wire it did
          increase the revs. This wire runs to carby. But the boat still isn't reving to what it should do. I am in the Ipswich area and we find it hard to get any help from anyone at marine places
