    HI-LEX controller

    Gee, what kind of motor do you have? MerCruiser I/O, IB or something else.

    Johnson Command Center

    It is easy to bypass the neutral safety switch. Simply connect the two wires together. The motor will now start in gear, at any throttle setting. The danger is that it will start at full throttle and cause injury. Why not replace the control? ebay should have something.

    How bad is it?

    What is the compression of all 3 cylinders? No cylinder head on that motor, just a water jacket cover over the spark plug holes into the cylinder. All pistons + crankshaft must be removed from the block for boring and honing. Pistons are $100+ each. Boring is likely about $75 each.

    1992 merc 90 2 stroke

    It is difficult to see what you have in the video. You should have red, black, black/yellow, yellow/black, grey and yellow/red as a minimum. Those are for +12VDC, ground, ign killer, choke, tach signal and starter solenoid, respectively. The voltage regulator would normally get the purple...

    Mercury 85hp runs fine on Muffs but Boggs down in Sea

    Glad it worked out. Unfortunately, current marine mechanics (and owners) are not well versed in adjusting the older carbs.

    Any concern using a boat in saltwater that has always been in freshwater?

    Actually, use zinc anode in saltwater. Outboards are designed to use in saltwater. Flush it with freshwater if you can. if not don't worry about it. Make sure to grease the steering rod a couple of times during the season.

    Getting heavy scale off of the outdrive

    On-Off cleaner is bad for metal. I think that is what you used from Starbrite. It has 3 acids and some alcohol, again bad for metal. Use some purple stuff and scrubby pads. If that doesn't get it, scrap, sand and prime and paint.

    Mercury 80HP Mounting on transom

    Depending on the boat (high performance or not), the shim may be a good idea. On high performance boats, they can lessen drag, w/o inducing ventilation. No way to tell w/o a water test.

    1978 Mercury 700 Control Box

    Info on controllers has always been hard to get, for some reason. The good news is that the function of the wiring is the same as most motors. The only differences are the electrical plugs. Since you need an engine wiring harness anyway, maybe source an available (Sierra) ADI harness and...

    Mercury 80HP Mounting on transom

    You need two 3/8" bolts in the base of the transom clamp slots. There are 2 holes each on the power trim brackets. it is very important that the PTT brackets be bolted, as the power of the motor is pushing against those brackets. Not sure how to answer your question. Perhaps the PTT...

    Black Max 150 overheating and water pressure

    40PSi is not usual for that motor. The poppit should open at about 15PSI. Since the motor is new to you, I would replace both thermostats and rebuild the waterpump. I would also repair the poppit valve. make sure you have the exact year of the motor. Thermostats and waterpump kits are...

    1978 Mercury 700 Control Box

    I have not seen a wiring harness like that before. It is different than my '77 and my '73 Mercs had. You do have ADI ignition which helps narrow it down. I would see what Crowleymarine website recommends. Look up your serial number on the maxrules site and see what year it thinks you have...

    Epoxy type to use in water jacket

    Marine-Tex is a good product. I have never used JB weld. Your fix sounds like it will work with most any epoxy. Make sure the water jacket area is sanded with fine paper and wiped with acetone, before applying epoxy. Fill the hole and overlap the hole with as much thickness as you dare, as...

    Motor wont start

    Clean your battery connections, and starter solenoid and starter positive and ground cables. The motor must crank pretty fast to make a strong spark. The motor will fire much more easily when using starting fluid. When using starting fluid, always have a fire extinguisher at hand ready to go...

    Where might I find a repair manual of a 2003 200hp Johnson 90 deg engine.

    Marineengine web site had manuals. Have your model number ready.

    1978 Mercury 700 Control Box

    That motor likely has the old external quick disconnect on the starboard side of the motor. There are likely lots of them around used. Search flea bay under MerControl. What wire colors do you have? I would expect that motor, if 1978, to have an ADI ignition and multiple coils. I thought it...
