    Thru hull leak

    So your hull is cored? If that is true, I would think you need to cut the rotted core material out and rebuild it with new core material and new inner fiberglass. Then a new thru hull fitting will be installed. If you do not cut out the rot, I think it will continue to rot, even if you stop...

    1988 60hp 2 stroke won't start Need help!

    Mercury OBs need to have a specific idle pickup timing, where the carbs are ready to open, but still closed. I would expect that to be 0-9*ATDC on your motor. The max spark advance should be about 21*BTDC. Of course to set these you need to rig up or get a timing pointer and adjust it...

    1988 60hp 2 stroke won't start Need help!

    The timing pointer is #17. It looks like it bolts to the spot next to the starter. You should set the motor to TDC with a screwdriver and see if the TDC mark is in that area. it should be obvious if it is correct, as off 1 spot is 45* out of time...

    Looking at a Johnson 120hp, what to look for?

    For all outboard motors, if you want to determine condition, look at the big ticket items. If they are good, and the price is reasonable for any other repairs, the motor is a good choice. The big ticket items are compression, gearcase and to a lesser extent, electronics. Electronics become...

    Kill switch location

    It never came with kill switch lanyard style one. That motor likely has a mercury switch that kills the ign if the motor kicks up out of the water.

    1988 60hp 2 stroke won't start Need help!

    Yes, they were just pieces of heavy plastic, with some adjustment. I used a piece of sheet metal, but most anything that has some stiffness and will fit will work. Are you sure the outer flywheel is installed properly? It is easy to get it right.

    1988 60hp 2 stroke won't start Need help!

    You can make a timing pointer. Something that bolts on and points to the flywheel and has some adjustment. A piece of sheet metal with a scribe mark works. Reed valves almost never go bad. If you truly have spark, get the timing close and she will run for many seconds on ether.

    Broken Skeg Tip...Repairable?

    Props are a lot cheaper to wear down than gearcase skegs. So either pull the drive up (best) or repair it to protect the prop. I paid about $250 to repair a skeg, 15 years ago. That includes the replacement skeg and the welding. I pulled the gearcase myself.

    1988 60hp 2 stroke won't start Need help!

    Gee, First pull the spark plugs and remove the prop. Now set the top cylinder to TDC using a screwdriver int eh spark plug hole. The timing pointer should read very close to TDC on the timing decal. If not, the outer flywheel is installed incorrectly. Next, stick a timing light on the #1...

    Big differences, same power?

    OK, so the newer motors had 10% more displacement, and made the same power. That is not unusual. The 1977 Merc 90HP, 115HP and 150HP motors shared the same displacement, number of cylinders, num of carbs etc. My merc V6 has 25% more displacement than my Il6. but makes the same HP. Maybe...

    Sunbird boat antenna location

    When I install a stereo in my boat, I put a 3-4' wire in the antenna port and toss the end of the wire into the bilge. Fiberglass boats do not shield the antenna, so no need to have a "real" antenna.

    Need advice, 1996 125hp no spark now, won't start

    CDI Electronics is a manufacturer of stators, switchboxes and other stuff. Their test procedures are designed to help you figure out which of their components you need to buy to fix your motor. As far as I know you only need a DVA to test your ign system. There are instructions on this forum...

    Smokey Engine - Air/Fuel problem or Oil/Fuel problem?

    Check the fuel pump diaphram for damage. A damaged diaphram allows raw fuel into the crankcase. This can cause lots of smoke.

    1982 Mercury 90 HP Choke Question

    Inline six right? There should be two plastic choke plates that close on the top two carbs.

    1976 mercury 1150 115hp runs on muffs but not in lake

    Make sure your starter is spinning at 300RPM or so, to help it choke up.

    1976 mercury 1150 115hp runs on muffs but not in lake

    No, as long the the primer bulb is hard, the carbs have fuel. Choke the crap out of her. Cold start lever high, hold choke button while cranking, until she fires. Hold choke for a bit and then feather it out, until she is warmed up. Make sure the voltage on the switchbox red and adjacent...

    I am pretty sure this is the one you need for a standard MerControl. If you visit a dealer, he will likely have one, or can get one. https://www.crowleymarine.com/mercury/products/54211t-switch-assy The solenoid wire, terminal "S", needs to be wired thru the neutral safety switch. The...

    Prop Locking Question (Reverse Locking Cam?)

    You could certainly get a bad gearcase on the cheap (maybe even free) and swap your stuff into it.

    New at this need help

    The newer Merc compatible controls will work with your motor, with some modifications. The control cables for shift and throttle should work w/o any mods. You should be able to reuse your existing control cables with the new control. New wiring often comes with new controls and would usually...
