    72 Thunderbird Formula w/twin 165hp Mercs

    The neutral switch gets put inline with the yellow start wire. In the wiring drawing there is a tie spot. In you current setup you can start the motor in gear or out. The neutral safety switch goes inline so it will only start when the switch is closed in neutral. Note, when in neutral there...

    2007 mercruiser 5.0 MPI overheat

    Ah yes and NO. Yes they have dry joint exhaust manifolds and elbows but that just means that the water does not pass from around the exhaust holes around the exhaust hole, in pass thru a side port opening and then into the elbow. The following is for open cooling, not closed You have this...

    need help with diagnosing bilge pump

    This is the typical bilge pump wiring, so look for the inline fuse feeding the pump. Wire might come off the Bat switch or Bat (Bat switch in pic should be on other side or red dot). Need a meter to check power.

    Where do these wires go?

    The one looks Tan and the color chart shows it to be Temp switch to warning horn or gauge. The other looks like Brown/wht so that should be trim gauge. If I see the colors right

    Removal of MEFI 4 system from 6.2L V8

    Not VP guy but that plug appears different then the Merc 10 pin plug (VP left, Merc right). I'm sure you could buy the engine harness from VP dealer which would be the first thought. Looked up a GL model (thinking this is a carb motor) and found the engine harness for $969. Or get a Merc...

    72 Thunderbird Formula w/twin 165hp Mercs

    Go figure the manual tells ya how to remove the amp meter and install the volt meter. So what they are saying is the White wire is used to power the meter (same as purple on new design). Tape the Red/White back, and connect the Red to the Red/White. They do bring up a great point which I...

    72 Thunderbird Formula w/twin 165hp Mercs

    Yes it will work Note, White wire is used like Purple in todays wiring. New wiring does not use amp meters so they don't have to run heavy gage wires to/from the helm. Just cut the Red/Wht loose and attach to starter (orange) You could either run Red to switch (Orange) and remove and cap...

    72 Thunderbird Formula w/twin 165hp Mercs

    Sorry but been out all day. The purple wire previously mentioned previously was thinking that you would be using a Mercruiser hiring harness, or using the color code Merc uses. Here is Merc color chart Purple is a switch color from the key. The pic about the two wires on the oil pressure...

    Well cannot say that anymore, but took my spare B3 and put the below style muffs on them For the test I used a 3/4 hose from a 4 foot frost proof hydrant on full. Water pressure around 85 psi. Had a garden hose ball valve (cheap ones) on the end and the valve was attached to the muffs. The...

    Would like to know how it sits with no one on the boat? Trying to figure out if the hull has taken on water, something heavy is on one side compared to the other or something else. Does the outdrive have a torque tab on it? Looks something like this

    Port 1900 and 547 Block

    This has started a couple weeks ago and been searching the net and found some info but the polling is happening about every second now. Not real sure but I think it started after either going to a pic link posted by a member at an offsite but was not a regular one. In about the same time I...

    Electrical Wiring Assistance Requested

    Do not connect the 24V wiring to the 12V. You can put a single bat switch in the main hot wire feeding the trolling motor just past the fuse. Most folks don't install one because the motor has an on/off switch built in with the power control. If yours does not, installing one should be good...

    Electrical Wiring Assistance Requested

    Howdy Since you motor is pull start the two banks can be setup separate, but maybe later if an electric start is used it could be an easy conversion. Here is the basic setup. The pic shows using a fuse and switch panels and the mains come from the one battery using a 10 AWG wires. The ground...

    Trying to find parts for posting on Forum

    On the Merc and BAM sites, I can look up by serial number, type and/or year. As GA pointed out, on the main parts page there are two Merc links on the left, top is outboards, bottom is sterndrives. The issue is you have to click on it to figure this out. In the search field it's not working...

    Atwood Surge Brake Dragging

    Your issue with only one wheel leads me to a brake cylinder, line or fitting. The springs in the axle should be retracting the shoes, so if their not doing that then check your brake cylinder first. If the brake cylinder hangs the shoes will also drag. In most cases it will not be the line or...

    Mercruiser 4.3 info 4 parts needed

    You don't have risers, they are the blocks on the right of the pic. Agree with Rick, drain then take the elbow off and have a look. Bolts and plugs can be reused if they are undamaged, but if you do need new ones, they come with new plugs
