    Honda 50 idles rough

    My Honda 50 is about 10 years old and each year appears to run a little rougher at idle or slow troll. I have read a number of past posts which state that the jets are a very narrow diameter and can clog up over time or with gas left for long time in carbs. Do the jets need to be replaced or...

    Flywheel removal for 6.5 Johnson

    I have read a number of past posts regarding the use of a puller to remove flywheel, but am having trouble loosening the bolt that holds it down. Not sure whether it is a reverse thread or comes off counter clockwise. Trying to hold flywheel with strap wrench is difficult. Any suggestions...

    Honda 50 Oil Pressure

    I started my Honda 50 after 2-3 weeks of not using it and it started fine. As I went to trim the motor from full vertical position the alarm started to beep. I left the motor in the down position and it ran fine. Afterwards I checked the oil level thinking it was low and to my surprise the...

    Poor idle when cold

    I have a Honda 50 which starts fine when engine is cold by giving it some throttle. However, I have to leave the throttle on for quite some time until the engine warms up. Is there an idle adjustment or some other setting that needs to be set to deal with this warming up issue? Someone...

    Fuel tank sending unit

    My fuel gauge is stuck on empty. I have taken sending unit out of tank and it reads proper resistance. Once returned to tank, it works for a few days and then back to empty. This has happened twice. It appears that cork float gets saturated with gas and then sinks to empty position. Is this...

    motor won't tilt in forward

    I recently bought a used 20 hp mercury that won't tilt up when in forward gear; tilts up when in reverse. I was told by someone at work that this may be due to lower unit not being reinstalled properly after water pump impellor replaced. Something about the shift lever being in the wrong...

    High Engine revs when towing skier

    My 4.3 litre Mercruiser usually revs around 3000 when towing skier at about 25 mph. Yesterday the revs were at about 4500 immediately upon getting the skier up and stayed there while pulling the skier. When cruising without skier later the revs were at 3000 again. Not sure whether this could...

    Increased tachometer reading

    The tachometer reading on my Mercruiser 4.3 has dramatically increased for the same boat speed; almost overnight (3000 rpm to 4200). Engine doesn't appear to be louder but can't be sure. The prop may have hit a sand bar while kids had boat out. Is it possible that blades have been bent to...

    Speed indicator not working

    My speed indicator has stopped working ever since the boat released from its mooring and drifted onto the sand for an extended time. The boat has an external sensor which is a plastic wedge at the bottom of the hull. This sensorappears to operate on a vacuum or difference in pressure since it...

    Honda 50 alarm

    The buzzer alarm of my Honda 50 has started to activate although both the oil and temp sensors appear to be working. Water comes out of the pee hole and oil level is fine. The alarm only goes off once the motor is in gear and the throttle is moved past a slow troll speed position. The alarm...

    Starting Mercruiser

    When I attempt to start my Mercruiser 4.3 litres, sometimes the starter does not turn over on the first or second attempt. Once it turns over, the engine starts fine. Not sure whether the problem is in ignition switch with key or whether the starter is suspect. Is there a safety contact in...

    Motor anti-tilt locks in forward not reverse

    I received a 20 HP Merc, about 20 years old, as a gift and it has a problem that the locking mechanism to keep the motor from tilting up engages when the motor is in forward gear rather than reverse. It appears that the shift lever operates in the correct direction to engage the latch, but the...

    low pressure tire conversion on trailer

    I would like to replace my regular tires with "low pressure" tires and rims to allow me to launch boat on sandy beach. I understand that wide low pressure tires won't sink as far into the sand and hope this will allow me to use ATV to move trailer. Trailer is Eagle for 18 ft. Wellcraft. The...

    Engine Rattle at high speed - Honda 50

    I have a 1999 Honda 4 stroke 50 which starts, idles and operates fine up to 4500 RPM. Once it exceeds this RPM it starts to develop a rattle sound which gets progressively louder as RPM increases. It does not make this sound while the engine is still cold but once it gets warm the rattle...
