    Mercury 84 & 82 90HP 2 stroke questions

    Does the #5 spark plug look real clean? If so, you could have water intrusion, which is more likely than bad reeds.

    1962 Evinrude Starflite IV 75hp no spark HELP!

    Inspect the coil for cracks. They will be obvious. Replace coil if cracked. Leave the distributor cap off and check for spark at the brass button on the coil. With a slow spin of the distributor pulley, the spark will give you a good jolt. You will be immediately convinced that the motor...

    Hull form versus engine power and torque In maintaining a boat on plain

    Planning at low speed is a function of the hull design and available HP at a given RPM. So a boat with a lower pitch prop, will have more power available at a given RPM, and will plane at a lower speed than the same boat with a higher pitch prop, provided the hull will allow the lower...

    Help with motor height adjustment

    Cavitation and ventilation are two different things. Monkeys post was about cavitation, Marks was about ventilation. Outboard motors have an anti-ventilation plate to combat the latter. This should ride on the surface to ease any ventilation. Different style props have different degrees of...

    Experience of Turning Point props? Prop failures?

    I use them in 3 blade on my light fast speedboat (23P 16 foot 135HP Merc), and in 17P 4 blade on my heavy 21 footer, 150HP Johnny. I have never had an issue.

    1988 SeaRay Seville 135HP

    The engine oil reservoir should never be empty. I would check the fuel to see if the motor is already premix. Look for an oil color dye like blue or green. If not, fill the reservoir and add oil to the existing fuel to make it premix. That way you can safely run the motor until you figure...

    Buzzer alarm wiring

    Some of those 4.3 also have a sender for water temp, separate from the buzzer sender. Look on the thermostat cover for both of those.

    Buzzer alarm wiring

    A lot of those 4.3 motors have buzzers for low oil pressure or overheat. I believe the sensors for both system ground their wires to the block. The sender for oil pressure to the gauge is separate from the low oil pressure sensor.

    Won't trim up under load

    What year motor? Some motors have trim limit switches which are adjustable. Some have 3 cylinder PTT units. Two trim cylinders will trim motor a bit. The third cylinder is a tilt cylinder which is too weak, by design to tilt the motor under anything other than idle speed.

    1977 johnson 115. Idles up to 6k but won’t push boat up on plane

    If the motor spins 6000RPM and the boat doesn't move fast, the prop is likely spun and slipping.

    Mercury Black Max Problems

    Constant alarm is probably overheat. So rebuild water pump with a new impeller, wearplate and 2 gaskets. If lower part of pump is melted, replace that as well. If upper part of pump is melted or cracked, replace it. Check and test thermostats. They do wear out. Retest operation of motor...

    Throttle and shift cable for mercruiser

    MerCruisers have an upper and lower shift cable. The lower shift cable goes to the outdrive and connects to an ignition killer switch, on the block, near the upper shift cable. If the lower shift cable binds, the switch is activated, and the ignition is killed. You might check for this...

    so Vee drive and rudder? A zinc anode on the rudder with the right shape will perform as a torque tab.

    Help with motor height adjustment

    Setting the motor up for best speed, may not allow you to pull a tube, without prop ventilation. It is the nature of pulling tubes. So you may need to lower the motor a bit when pulling tubes.

    1988 v135 reassembly help

    I am not sure what a "working unit" is. Are you trying to install the upper shift shaft? It is normally installed before the powerhead is installed, as it is under the carbs, and sometimes the block. Did you look at the parts diagrams on sites like crowleymarine?

    locating PS leak on 2001 Mercruiser 5.0L EFI alpha one gen II

    Sometimes they leak into the cooling water at the cooler. In that case, you may see the ATF bubble up in the water, or you could pull off a cooling hose and look for it there.

    Hard steering going left

    Most outboard motors and sterndrives have a zinc or aluminum fin above and behind the prop. These can be turned to help balance the steering. See if you have one. The zinc variety of these fins (AKA torque tabs), also act as an anode to help stop galvanic corrosion of the gearcase. Power...

    Outboard repaint - need suggestions on materials

    Briteside is for above waterline use. However, as long as the motor is tilted up out of the water, it is fine. It will not fail until submerged for a few days.
