    I cant get this throttle set up properly. Please advise.

    That, can explain a lot of the problem. If it were an actual Book, it would belong in the Outhouse, and not for reading. In the section regarding the Link and Sync, While some of the Basics are correct, it is making references and showing images of what to adjust on other motors, which aren't...

    I cant get this throttle set up properly. Please advise.

    That would be one of the Adjustments for the Spark to Carb Sync. I thought you said you were using a Service Manual?

    I cant get this throttle set up properly. Please advise.

    If I had your motor, I would have no hesitation setting the Timing at 28, I would also make sure I wasn't over propping it. If you're worried set it at 26, as 24 will drop your HP quite a bit For the first 75% of the Throttle Lever Movement, the Carbs remain Closed, they really only start...

    I cant get this throttle set up properly. Please advise.

    So which control box are you using? Photo If the Books says 28 degrees use 28. The timing is already retarded from what they used in the early 70s. You will have to redo the Link and Sync after. Are the Carbs fully closed at Idle? If it has trouble returning to Idle after giving it 'Juice'...

    I cant get this throttle set up properly. Please advise.

    At this time Forget about the Cable. Get the Engine set up and running correctly. Once that is all fixed, and the Idle Speed is Correct, Adjust the Cable Length as needed. Now inside the Control Box, is there more than One Mounting Spot for the Cable End? Also, is there a chance you have the...

    I cant get this throttle set up properly. Please advise.

    Put the control lever in neutral, that should have the Cable at Idle, place the Throttle Linkage against the Idle Stop, adjust the Cable Length, until it is the length needed to fit on the Linkage, then a bit more to push the Linkage against the Idle Stop slightly. Might have been a bit easier...

    I cant get this throttle set up properly. Please advise.

    So the Cable Length needs adjusting. In one of the Pictures you can see the Threaded brass of the Cable, there is an adjustable Trunnion there to adjust the Cable Length. It is generally used to put a bit of Preload on the Throttle Linkage to keep the linkage against the Idle Stop. In this case...

    I cant get this throttle set up properly. Please advise.

    First of all what Engine? Second, what are you using for a Service Manual? Third, what have you fiddled with so far? Forth, When you say you can't get the Throttle Valves Horizontal, was that with or without the New Throttle Cable connected?

    Reenforce glass hull under the waterline? - 1967 StarCraft

    Interesting pic of the Stringers. Are the Stringers each one long continuous board, or are they several short pieces?

    1997 Mercury Optimax won't get on plane or stay running after first run.

    Welcome to iboats Since that is a DI, engine and there is a Computer Controlling it, I recommend you take it to a Mercury Dealer. Throwing parts at is going to get expensive. From what you wrote, it runs fine on the Initial Run, from a Cold Start. Might be a Heat Soak issue on some of the...
