[@keithsk-gaming9820]

My opinion is that Motors that are right around 10 horse power are a great size for a rowboat. They don't suck down the fuel and put out plenty of power. I personally have an 8 horsepower Mercury and it runs great on My boat.

[@oldjohnnyrude8404]

I tend to agree with you that the power to portability balance of a 10hp motor is about perfect. My favorite all around motor is the OMC 18hp. They are a little bit thirstier though. Thanks for watching!

[@bryanhollis807]

Tell me more about the fuel line adapter.

[@oldjohnnyrude8404]

@@bryanhollis807 There are two adapters in use on this motor for this video. Going from an OMC pressure tank I made an adapter to be able to draw fuel through the fuel side of the dual line hose and draw air through a filter into the air side of the dual line hose. The air side becomes a vent to allow air into the otherwise sealed pressure tank so fuel can be drawn out via a pulse driven pump on the motor. A motor side fitting from a 1950s OMC outboard plugs into the fitting on the pressure tank. The other end of.the adapter is a standard OMC single line fuel fitting that would fit any sing line style OMC outboard. The other adapter uses a male OMC single line fitting on one end and the small female Mercury bayonet fitting on the other to get from the single line OMC to single line small Mercury fitting that fits this motor. I hope this helps. Thanks for watching!

I just bought the same motor… last owner lost the impeller key, and I can’t find a picture of it anywhere since I’ve been trying to create my own impeller key for it. Just curious if you have any idea what it looks like?

[@oldjohnnyrude8404]

I made an attempt to answer your question over a week ago and apparently KZbin didn't publish it for whatever reason. In any case, congratulations on your motor. If I remember correctly, the impeller drive key for this motor is just a short piece of round steel or a dowel that rests on its side against the flat that is machined into the drive shaft. I use a but of Vaseline or grease to hold the round "key" in place on the drive shaft while the impeller is placed over it. The rod does roll a little and allows some movement of the impeller but keeps it from freely rotating independently of the drive shaft. I hope that makes sense. Thanks for watching!

[@TheSturgisStudioz]

I have the same motor. A 1962. I'm having issues with it surging. It ran fine. But now it lost half power. I had only changed the fuel and length of fuel line. 10 ft was too long to hold a siphon. And not sure if I can run ethanol fuel... those changes led to it Won't even wake out or push just a air trail under the water. Idles fine, but when applying throttle it bogs out. I'm Wondering good things to check? Thanks because I'm not very smart with outboards. Also does this particular motor need a pressurized fuel tank or just a prime bulb tank. And does it need "no ethanol" gas 91, or can it run plain old unleaded with the mix. Im gonna try soo. Just a mix with regular unleaded and see if it acts normal again. Also I did change spark plugs. But any info would be highly appreciated

[@oldjohnnyrude8404]

I would recommend staying with non-ethanol fuel in any of these older outboards. The lines and pump diaphragms were not designed to handle the ethanol in the gasoline. Ethanol also phase separates when it encounters enough moisture, which happens more quickly in a marine environment. The phase separation is a corrosive solution that adversely affects carburetors. The loss of power may be a plugged carburetor or it may have dropped or is intermittently dropping a cylinder. These things will run surprisingly well at low speed on one cylinder. I hope that helps. Thanks for watching!

[@chrisambrose8838]

TheSturgisStudioz I have a 1964 9.8 and it did the same thing....take the carb apart and clean it good...get all the passages open and she’ll run great. You may have to open the idle screw if it Boggs down when you start out.

Good old engine you got there. Does your propeller have 2 or 3 bades?Did they have both 2 and 3 blade propellers?I have a 62 110 9.8 twin as well. My 62 has 2 propeller blades. Is there any chance to go on a 3 blade propeller for these older models?

[@oldjohnnyrude8404]

Sorry for the long delay. This motor has a 2-blade prop. I'm not sure if this one has a 3-blade available or not. They did change the spline count on the prop shaft somewhere along the way. I have a '79 110 with a 3-blade and the props do not interchange. Thanks for watching!

[@nicolascolby7892]

How is your fuel line set up

[@oldjohnnyrude8404]

During this video, this motor was running from a 4 gallon OMC 2-line pressure tank. I had an adapter on the tank line to change ot to a single line OMC connector then a second adapter to go from.the single line OMC connector to the small Mercury bayonet connector to hook up to the motor. I have a box of adapters I have put together to be able to run lots of various makes of motors from OMC single line tanks and then the adapter to run single lone OMC from the 2-line tank so I can run anything I own from a 2-line OMC tank. Thanks for watching!

[@jaguarguy01]

Picked up the same motor from a friend and the lower unit was picked apart. Any ideas on what other years and model merc lower units will fit it?

[@oldjohnnyrude8404]

I have a much smaller base if knowledge about Mercury outboards than I do OMC. I have a 1979 Merc 9.8 also and the lower units are very similar other than the color. I cannot guarantee they will interchange, but it seems like they would. The 70s 7.5 Mercs will interchange with the same year 9.8 also. I'm thinking this is a pretty common lower among this size Mercury. Thanks for watching!

[@joeblo4306]

Hi there! So I’ve got one of these and it’s little brother... the 6. I’ve also got an old Mark 10 that I’m working on. All three of them sometimes have a tough time deciding between running on 1 or both cylinders, especially the 6 and mark 10. Do you know what could cause this? I’ve changed the plugs in the 6 but they seem to darken up really fast when I run at full throttle. Any help would be much appreciated. Thanks, Matt

[@oldjohnnyrude8404]

If it is sporadically dropping a cylinder, it could be the plug wires, dirty points, or bad condenser(s) as well as the spark plugs. Check those and see if any of those things help keep it running. This one needed the points cleaned a bit, but after that it had good spark on both cylinders. Thanks for watching!

[@bradtocher8818]

Cool video. I just picked up one of these and would appreciate some guidance. What's the fuel oil mix on these 50:1? What plugs are you running too? I got it with J8C Champions (very old)

[@oldjohnnyrude8404]

Congratulations on your motor. I would suggest cleaning the points, checking out the fuel lines, cleaning the carburetor, replacing the water pump impeller and gear oil as a starting point. The spark plugs may need to be replaced as well. I'm pretty sure I am running Champion J6C plugs in mine. I don't think you need to run as hot of a plug as the J8C unless most of.your time is spent trolling. I'm not sure what the factory reccomended plug for this motor is. These motors are OK to run on 50:1, but 24:1 was the ratio when they were built. Mercury did post a service bulletin once they introduced their own oil stating 50:1 could be used (if using the Mercury oil) in all of their motors since they are "fully jeweled" meaning they are full roller bearing engines. Any TCW-3 rated oil today is sufficient to run these at 50:1. Thanks for watching!

I believe the pump in a Merc 100 is farther up the leg and is a cartridge that has to be removed to get to the impeller. I have never worked on one of those motors. I'm not sure of the proper procedure to replace that impeller. They are fairly probe to failure if they have been sitting a long time though. The impellers are fairly small and do not do well with sitting for extended periods of time. It probably does need to be replaced.

Great little motor. It will likely need a complete service after sitting for that long. At very least a thorough cleaning of the carburetor and the points will need to be cleaned and adjusted.

[@oldjohnnyrude8404]

I don't remember now if these coils are riveted or not. I would not be surprised if they are. The laminations on these were machined to fit the flywheel contour after they were mounted to the plate. Are your coils cracked or otherwise obviously damaged? Have you cleaned and readjusted the points? You may also have bad condensers. Unless the coils are visually damaged there is a good chance they are still OK. I would have to get mine apart again to comment on ow you would change your coils if you needed to do that.

Congratulations on your motor. If I remember correctly, the impeller key for this motor is just a piece of round rod maybe ~3/32" in diameter the length of the flat onnthe drive shaft. The rod just sits on the flat parallel with the drive shaft and the groove in the impeller fits over that little rod. It allows some radial slop, but it will drive the impeller reliably. I use a dab of grease or Vaseline to hold the rod on the flat while I place the impeller over it. I hope that helps. Thanks for watching!
