    Motor swap, back and forth.

    Steering swaps pretty easily between motor makes. The electricals and control cables do not. For those the same brand motor is good.

    Merc 3.0 Overheating

    Compression can leak into the cooling passages, causing overheat. You can run it and check for pressure in cooling system. Not sure offhand how to do that, though.

    Can you drill the manual release hole oversize and tap for a flush bushing?

    Merc 3.0 Overheating

    Check your compression. A leaking head gasket can also cause overheat. Was the boat always used in freshwater? Exhast manifolds in salt water only last 10 years at most.

    Garboard drain assembly

    A lot of garboard drains do not have tubes. Seal the transom wood with epoxy or polyester resin. Seal the garboard fitting with silicone.

    Trim wiring.. 5 wire tt

    Gee, five wires: Red is power into the PTT system, Green is down, Blue is up, Black is usually ground. So that leaves 1 wire. How is the harness routed.

    So you are asking if someone modified your wiring? That is a tough ask.

    Fuel setup two outboards, one tank.

    Guy, That probably works, in theory. to go further, I would expect that to work. Let's see if it does... Maybe we are chasing wild geese.

    4 stroke

    Some of those small motors have a fuel shut off valve. I recommend you keep is closed whenever the motor is unused. Leaving the valve open, with the fuel tank above the carb, allows the carb to be kept full of fuel, and as the gasoline evaporates, varnish and other stuff can build up clogging it.

    Replace mount

    Newer motors of your HP (late 80s or newer) use four 1/2" transom bolts. Those are more than strong enough to keep the motor bolted to the transom, even under crash conditions. The "lip" on the transom bracket may (may) be used to help hold the motor to the transom, until the transom mounting...

    Fuel setup two outboards, one tank.

    Gee, I can see a scenerio where you are running on the kicker for several hours. During that time the gas in the carbs of the big motor evaporates, lowering the float and exposing the inlet needle to the air in the carb bowl. Carb bowls are vented, which allows the kicker to suck air. Now in...

    Trim wiring.. 5 wire tt

    You have one of the newer designed PTT units, with two trim rams and one tilt ram. When your motor is down, and you run the PTT unit in the up direction, the twin trim rams move the motor, which can be under full power. After those trim rams are fully extended, if you continue to operate the...

    can someone point me in the right direction?

    Dave, A lot of motors have a trim limit switch, separate from the trim angle sender. Not sure if he has one. The crowleymarine site would tell the story.

    Fuel setup two outboards, one tank.

    Check valves in primer bulbs are usually worth about 2 cents. The check valves in the fuel pumps are much better. However, it could be that without shut off valves, one motor or the other will suck air from the other. Test is and see if the check valves are sufficient.

    1976 chris craft lancer steering wheel removal advice.

    That steering looks to be rack and pinon. If you only need access behind the dash, pull the bolts holding the rack to the pinon. The center part of the steering will still remain, but most of the wiring will be exposed.

    Gas

    How tall is the tank? Short tanks only need a bit of bow raise, and a fuel pickup in the bow, to have the fuel pickup tube suck air. With a short tank, you will want the fuel pickup in the stern of the tank.

    Hot Mess

    You also might see if the new mechanic has experience with the older motors, like yours. Maybe look for a mechanic in his 50s or 60s. A lot of shops will not work on motors older than 20 years. I presume you boat in freshwater.

    Mercury xr2 not turning over

    Sure, start it on a flusher. Keep the engine speed to idle. After running it, smell any oil that you see. If it smells like gasoline or oil, it is fuel. If it stinks like rotten eggs, it is gear oil, and you likely have a leak. Mercs often leak at the waterpump base seal to the driveshaft...

    Four Winns hull strength

    Yes, the SeaRay hull cracked once and deformed once. The center of the hull under the ski well deformed. I repaired that, from the inside, and some time later, the port strake cracked the long way. The fiberglass under the ski well formed the keel of the boat. When the ski well hatch was...

    are these wires supposed to be connected to eachother?

    Trace them out. The tan is usually overheat alarm sender and the brown/white may be for a temp gauge. Perhaps the PO removed the overheat sender and replaced it with a temp sensor?
