    Ignition wire gauge?

    Gee, I was able to solder a new wire to the female ign connector and solder it to the boat harness on my '77 Merc 1500. It lasted years. I drilled into the female quick connect plug from the rear and pushed out the female connecter, if memory serves. Of course it was probably 30 years ago.....

    Unable to identify what lower unit rebuild kit to get.

    That 0G number is your serial number. Punch it into the crowleymarine web site and it will give a year, model and parts list. If they have a seal kit it should be listed. If not, there are other parts places that you can look it up. Try ebasicpower, a sierra catalog or maybe iBoats.

    2005 200hp Mercury Optimax Water in Gas

    Optimax motors often have fuel filters, with water sensors mounted under the cowling. Did you empty/replace that one?

    WARNING !! WARNING !! About brand new sparkplugs I bought.

    Gee, it is standard practice to gap new conventional spark plugs, no? Iridium plug gaps are usually set at the factory, because they can be damaged if the used tries to set their gap.

    1979 70 hp choke issues

    Do you mean "where does the ign killer wire from the ign switch go on the switchbox?" The ign killer wire on your motor was probably (I say probably as the wire colors changed about that time, say 1980) orange or salmon. The newer wire color is black/yellow. See which one you have and...

    1979 70 hp choke issues

    I have never taken your exact model engine apart, so I am not familiar with the cowling, cowl support and other things having to do with engine configuration. Sorry.

    1979 70 hp choke issues

    Clearly the PO was not well versed on the wiring of that motor. Disconnection of the killer wire, and a jumper on the starter solenoid (prop removed for safety) is all that is necessary to start the engine. On those MerControllers, the ign switch is soldered to the wiring harness. I would...

    1979 70 hp choke issues

    When you say "kill switch at the switchbox", do you mean the mercury switch that kills the ign when the motor is tilted?

    Ignition wire gauge?

    What was the original gauge? All the wires in the loom (harness) were the same, except for the battery cables. Check the ign wire at the quick disconnect plug. It should be the center one. They break there often. I was able to repair my ign wire at that point with some drilling to expose...

    1979 70 hp choke issues

    A 1979 Merc should have one coil per cylinder. That will mean it has ADI ignition, which will generate spark w/o battery power. You would need to disconnect the black/yellow wire at the switchbox, as the ign key grounds that wire to kill the spark. Connect the battery to the battery cables...

    WOT Question

    Your prop likely has too much pitch. You probably want a prop or 12P or so, but try consulting a dealer or prop selector. Unless the 'toons have some sort of rough coating like barnacles on them, I doubt speed with change much. 22MPH is pretty standard for 'toons.

    hard start after motor tilt

    You do reprime the carbs after tilt down, right? Alot of carbs leak when tilted up.

    What To Get?

    Well, 3 miles here in NJ is the limit that you can legally fish for Striped Bass. 3.1 miles and the Feds could get you. All kidding aside, if you are simply going for a ride, 3 miles is plenty far out. If it gets ugly, you can get back to shore is 10 minutes or so. If you want to fish at a...

    What To Get?

    Lake, river and ocean implies that you will trailer the boat? If so, a 25 footer will be a drag to trailer each day. I would think a 21 foot deck boat or dual console, with outboard power, would be a good choice. It will go most anywhere on the lake, will have no issue on the river, and...

    1997 Mercury 2 stroke 200 gets up to WOT then loses RPM's

    Check/rebuild your fuel pump. If the diaphragm leaks, raw fuel gets into the crankcase and causes fouling of the cylinders. On a good motor the fouling will clear up and the motor will run well at high speed.

    1996 Mercury 115 steering cable stuck

    If you remove the transom clamps, can you put a pipe wrench on the ends of the tilt tube? If you find a way to secure the engine (lay it on the ground?) you can hammer on the pipe wrench. Have you tried heating the triple clamp, spraying it with penetrating oil, and letting it cool? That...

    Purple instrument wire no power

    The purple wire is usually powered when the ign switch is turned on. It is used to run the gauges and their lights, as well as power the ign if necessary.

    Outboard mounting bolts

    That is the purpose of the slots in the lower part of the transom clamp. However, you still need to make sure the bolts are sealed to the transom. I would therefore recommend you loosen the nuts on the bottom bolts and remove the upper bolts. As you lift the engine, put some silicone on any...

    Outdrive Paint & Prep

    If it were me, I would find some aftermarket paint that matches the V-P color, and a can of Zinc Chromate primer and sand, prime and paint outdrive at the beginning of the season. V-P, Merc and the others charge way too much for "factory" paint. Since he trailers the boat, he can repaint the...

    What type of gas tank for '79 Johnson 35hp?

    Gee, I have a Moeller plastic 6 gal fuel tank I bought in 1985 or so. I left it in the weather for decades. It is a bit discolored but works fine. It doesn't leak, which is rare for those cheapos. I thought about spray painting it red again, as it is kinda blotchy.
