    Transducer cable through transom?

    how much work do you want to do? what is done on millions of recreational boats is drill a hole, feed wire thru, seal from both sides with 3M 4000UV and go boating if you dont like that, you can add cable glands. some like Roxtec are guaranteed to be submersion proof...

    no spark Mercruiser 120

    did you service the points? if not, start there the coil fires when the points open (or break) and the magnetic field collapses. you should be able to fire the coil by simply touching the coil - to ground and then removing.

    SX outdrive stuck or was now broke :(

    i know what I would do, however its a brute force approach. weld a ring onto the gear, hook a chain onto said ring, hook the other end of the chain to a tree and yank the sucker off. something will give, something will break. However it will move. you are already replacing the outdrive and...

    Omc cobra exhaust bypass

    its an idle relief port. at idle, the engine wont run with the back pressure that running thru the drive and out the prop has. at WOT the exhaust flow out the prop is helped by the movement of water which also provides some scavenging of the gasses.

    Starcraft boat market?

    a stereo, sparkly paint and vinyl surfaces sell more boats than aluminum did. the islander style of boat went out of favor as a fishing rig as the center console boats are gaining popularity.

    What´s the best replacement for AQ271C (or 570) 5.7 GM engine, ideally stroker?

    no, you would need to re-make the fuel line (post #74). as in re-fabricate a new line. your old line would not be usable as is or you can get any number of holley fuel logs and run A1-15 marine fuel hose if you dont want to fabricate (per post #74).

    Taking my 1984 LaveyCraft out of moth-balls

    your ball gears are getting close to their end. I believe the rule of thumb was replace when the nubs are 1/3 worn regarding going from 160 to 240, time to troubleshoot. use an IR thermometer. could simply be electrical in nature. need to look

    Interior stains - what are they and how to clean?

    if you want, I can supply you the phone numbers of the vinyl manufacturers. Sincerely Scott Danforth Engineering Manager Taco Seating

    Interior stains - what are they and how to clean?

    from the vinyl manufacturers themselves. dont believe me, call them yourself. anything beyond the warranty period is considered a bonus. since vinyl and foam manufacturers are no longer allowed to use arsenic as a fungicide any more, the warranty periods have dropped.
