    Thru-hull oil drain

    If the inspection officers never heard of a thru hull oil drain, then they are not as well experienced as they should be. Those have been around for quite a while. Aftermarket ones replace the drain plug on the oil pan and are routed out the garboard drain, when you want to change the oil.

    1987 mercury exhaust question

    Not sure your question has much to do with your leaking powerhead-to-midsection problem. You should clean the mating surfaces and replace the powerhead base gasket, to stop the leak. Normally the exhaust gas and some water are routed into the exhaust tube, down to the prop exhaust ports. Only...

    Constant beep when i accelerate

    Thermostat cools at idle and slightly above. Poppit then takes over. If you have had the motor from new, 15 years is a long time for the original waterpump. If you bought it used, it could still be 15 years old. It makes sense to replace the impeller, wearplate and 2 gaskets. If the base or...

    That is normally an overheat alarm. When was last time waterpump was replaced? Thermostats? Poppit valve?

    Did you have the distributor out of the block? Have you checked your timing? Make sure spark happens when the valves are closed for that cylinder.

    Starter issues

    Starter windings are generally not fused, as they can take 150Amps or so. The solenoid primary winding is fused, but takes 10amps or less. So either you wired the starter thru the fuse, or you have wired the solenoid incorrectly, say a dead short when you turn the key.

    Mercury 84 & 82 90HP 2 stroke questions

    Check fuel pump diaphragm. If they leak, raw fuel is introduced into the crankcase, flooding a cylinder and into the exhaust, which shows up in the water.

    Boat not getting up to speed

    The top cylinder has enough compression to allow the engine to run normally. That is not your problem. Spark must jump a 3/8 air gap. Are you sure about the resistance of those spark plug wires? That seems like very excessive resistance.

    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.
