Mercury 6 hp outboard gets a new water pump new gear oil 1966 vintage Merc60 as good as it gets

Today we service the water pump on a 1966 Mercury outboard and change the gear oil with my favorite oil from Amsoil 75w-90 lube. In this video you will get to see how flawlessly this 54 year old outboard still runs.

[@patrickclarke8893]

I owned the exact same motor in 1977. I'm from Sydney Australia. The water pump was like an alarm clock. You could guarantee every twelve months the thing would need to be replaced. Ended up selling the boat an motor few years later. Your video bought back fine old memories. Great work mate.

Water pump for a 66 or 67 mercury 6 hp 2 cycle?

[@woofwgn]

I have one of these in my garage. Bought it from the daughter of the original owner, out of his estate. I wanted one of these SOOO bad when I was 10 years old to push my rowboat. My dad said, "Maybe next year..." The next year, I of course wanted something bigger 😏 But I never forgot about the 6 hp. that got away. What good is eBay if you can't finally buy the stuff you wanted when you were a kid? 😄 Even these pre-1970 models that still have points and condensers run like sewing machines. With 7.2 cu. in. and twin cyl's, they're almost miniature. The decal for the shift lever is still on mine. "Up" is forward, "down" is reverse and level (horizontal) is neutral. I have a '69 9.8hp, it's the exact same. I believe they changed in '71, when they put the stop button on the side, forward of the shift lever, so they had to reorient it to get it out of the way.

[@danparker1925]

Thanks for the great videos. I have the same motor as your 1973 4hp. Between the two videos I have been able to go through and do the proper maintenance.

[@Michaelsbackyardmarina]

Great to hear!

[@ryanwise5758]

Great video! Good camera shots and great verbal explanations. I'm refurbishing a very challenging salt water run 1966 Merc 200, but have an old Merc 200-110-75-40 Owner's Manual, with a photo on pg 15, showing the shift lever pointing forward (horizontal), toward the bow of the boat (not up). In the photo, there is a decal underneath the lever, on the cowling, showing to tip the lever up slightly for Forward, middle position Neutral, and down slightly to Reverse. This seems to make sense the way the detents and gear shift bracket inside the cowling are set up. Whatever decal used to be there is long gone.

[@Michaelsbackyardmarina]

Great Stuff. Thanks for sharing.

[@mikephilipps1103]

What would you take for that 66 motor .

[@johnb5519]

My grandad had a Merc1968 9.8, and a 1975 4.5. They ran nice but the drive shafts would rust, and take out the seal on the water pumps, Then oil or gas would get in and swell the impeller and it would break free from the brass drive sleeve. I brought the driveshafts to a shop and had them hard chromed, and never had a problem again. I still have his old 4.5, and his 35 horse, Johnson golden javelin.

[@Michaelsbackyardmarina]

That’s a great fix for sure

[@keithinuk]

Thanks to your video, I have now replaced the impeller on a 66 Merc 60 I picked up, I replaced the oil in the gearbox and fabricated a new fuel pump diaphragm, I also had to use a larger fuel connector, as I couldn't find the right one, being in the UK doesn't help.

[@Michaelsbackyardmarina]

[@Michaelsbackyardmarina]

they are very differently engineered compared to Johnson's for sure.

[@chancecarico7737]

Mine has a front facing shifter. Yours is pointing up. When facing front, up is forward, down is reverse, front center is neutral. This is why I believe you had what appears to be a "reversed" setup. It is the orientation of your shift handle. Great videos and cool personality. Good job!

[@Michaelsbackyardmarina]

Thanks for sharing and thanks for watching

[@jeffreysmall5505]

The shift handle on a Mercury is designed to be in a horizontal position when the motor is in neutral, click it up for forward and down for reverse. Johnson/Evinrude the handle is in the upright position, so you pull it forward for forward, and backward for reverse. I noticed your handle was installed in the upright position like a Johnson. If you loosen the screw and rotate the handle to the proper position, it works and looks as it should.

[@Michaelsbackyardmarina]

Sounds about right.

[@robertsenkmajer5730]

The splined shift shaft needs to be checked and oriented before reassembling gearcase into mid-casting. Yes, the shift lever will be horizontal for Neutral, but the splined shift shaft will spin round and round. Need to work the prop shaft against the lower ratchet mechanism both ways to determine proper lineup

[@garrisonh]

Nice motor, good job!. On my Dad's 6hp Merc. , I seem to recall the shift handle pointed straight towards the bow when in neutral. We would push down for forward and up for reverse. I remember replacing the handle on my father's 6hp. I believe it was a friction fit with a pin??. I'm not sure though because it was 30 years ago.... If you can remove the handle and put it back on pointing down when in neutral I believe that's the correct orientation.

[@Michaelsbackyardmarina]

You would be absolutely right. pointing it down makes sense. Then pulling it forward for forward and pushing it back for back would work and make perfect sense. It would be a odd duck, all other outboards the handle is up.

Loving your videos while I am doing an impeller change on my 1972 Merc 40 4 HP long shaft. All of the videos I have watched show the flywheel rotation to be clockwise. My hood mounted pull starter rotates mine counter-clockwise and that's the way it runs. Impeller vanes face opposite of what the other videos show. Do you remember anything about this? Merc made many year to year changes in this era, including the direction you move the shift lever to go forward. I'm in the middle of an impeller replacement on mine. I'm in Minnesota. C'mon up, we have some extra lakes! These old Mercs really bring back memories. I was 16 in 1972 and was in a Boston Whaler with a 20 HP Merc.

Hi Michael, Been folliowing you for a while, same like you I have them stacked like furewoid here, mostly runners. Got a 1964 9.8hp Merc that is a Super-Sweety and having trouble keeping gearcase sealed. Its a twin for your 6hp Merc, I could go on cuz I'm a lifetime fanboy for Mercs (62 y.o.), but anyway, my shift shaft is corroded and having trouble finding another, NOS or otherwise. Looking into a Seal Saver sleeve if they are made that small. Or possibly braze and re-machine that surface where the seal contacts the shift shaft. Yes, the shift lever is intuitively backwards, but that's how that series runs. I've seen the double-reverse or otherwise on many Mercs, it's just a matter of aligning the blind spline properly as you did.

[@Michaelsbackyardmarina]

good information. Thanks for watching and commenting

[@georgeanddaddecker7563]

You should use more grease, it will extend the life of those seals and o rings. Use saltwater proof grease. Also apply it to the shafts as well.

I am now working on the exact same motor. There are a few issues that I've been able to take care of, but I'm not sure whether the motor is pumping water all the way through. I believe it should be coming out at the exhaust area just below the lower cowling at the rear. Should it look like a typical tell tale stream or does the exhaust kind of atomize it? Thanks

[@talktolee]

@RMDCreations - First off...THANK YOU for this video. I am trying to help my sons friend on a 1968 200 20 HP. Needs an impeller. I only ordered the impeller at this point so hope I don't need all the parts you ordered. The shifter thing had me for a loop as well, it is really STIFF on shifting so i will have to look at it when we drop the boot. When you put the boot back in, did you have it in neutral or in forward? Also did you have that gear spline with the missing spline like you had in the video pointed back? Also for the lower gear lube, how much (Capacity do you need?)/ Again thank you for the reference video!

Hi. I have a 9.8 hp merc. The upper oil fill hole is stripped and leaking water. Can I retap the hole. Previous owner had a 10-24 x 1/4 robertson screw (bolt) in there. I doubt that's the right thing. Recommendations? [e-mail]

[@owendavis2642]

thanks for your videos! they are helping me restore a 1968 Merc 6hp 60J that was purchased new by my grandfather. its been sitting in a garage for 25years. unrelated question to this video, but i need to replace a damaged piston and my manual is calling for item 703-3375A4. the only pair i can find online are 703-3375A5. I cant find any information on what the difference is between them. any idea? thanks again!
