1971 Mercury 20 Hp Outboard Motor




What do you think about this video?

teabaggervance8: I have a 77 85 hp thunderbolt, it runs like a scalded dog- it is faster than my friends 115..they built em rough and ready in the 70's

Greg Whitbread: That flies for a 40yr old 20hp!!

Greg Whitbread: That flies for a 40yr old 20hp!!

MeLuv2Boat: Hello! I like your video. You should think about submitting it to the Mercury Film Festival, starting June 3rd. You could win a free outboard or a fishing trip. You can find more information about rules, prizes, and eligibility at Mercury Marine's website. Good Luck!

CrazyCurtass: I've just picked up the same old motor from an older guy.Just bought a 14 foot starcraft.Hope she's going to work lol.I'm only one year older than the motor lol

Carb0nFiber: also a 2 blade prop? And why is it faster than a 3 blade? nice video, and as you said in a reply before my post,how many times you you drive this engine? (25 litre a whole summer..)

DHUNT571: what prop are you running? the two blade or the 3 blade??

Etrician55: or if u have problems finding it from the outside simply take the cowling off and find where the water tube runs to outside the engine

AIRb0ys: It's dont look that nice but HOW FAST??

James Agans: You better check to make sure you haven't sheared your woodruff key in the flywheel. As usual since its a Merc its a wierd size like 3/32. My son sheared mine right off by not taking up the slack. Also make sure your carb is real clean. Run some seafoam through it.

audvidgeek: Great little motor! That sound brings back many fond childhood memories of buzzing around the Chesapeake Bay with one of these on the back of my Dad's Lund 14 foot alumnium boat

Continental4328: wow, i have a 13ft OLD fiber glass boat with a 1975 20hp merc and a 2 bladed prop and it dose not go anywhere near that fast

DHUNT571: Only 2 props are available for this motor. 3 Blade -9 pitch (power prop) & a 2 Blade 11 pitch (speed prop) I have this same motor on my 12 foot Gregor and it does 33MPH at WOT. I'm looking into re-pitching the prop to 13/14 to see if I can get more speed out of it. Currently it pegs at 6100 rpm (33mph) hopefully I will get close to 40+MPH around 5400 RPM. Also, another thing I am looking into is finding a prop that is 14/15 pitch off a newer motor-having the 8 spline hub pressed into it

san379 .: i used to have one till ast winter when crackheads broke in and stole my 1967 merc 20hp never saw it again.. i liked it

Neal Adam: I meant to say, they seem to outperform johnson and every other motor in their day.

Peter Kalil: @larshamberg12341234 Hi Thanks we love this motor. It's really not bad on gas, I haven't even burned a 25 litre tank yet this summer.

Macey Mercer: I love that old timey look on mercury's.

J Mac: Those old Mercs are cool looking, kind of like the old Mercury cars.

Etrician55: at 1:17 of the vid thats probably as fast as the 9.8 series will go

Ivan Karpenko: How much would a motor like this Cost?

Peter Kalil: @lodestar260 Hi, the pitch of the props are different, the 2 blade has a longer reach per turn, that gives more speed. The 2 blade is 11 inch, the three blade is probably 9 inch pitch. I use the boat every 2nd weekend or so...

Peter Kalil: Look at the motor from the front, and it's on the left side. Starting from the back, run your finger along the ridge below the "wings" and it's at about 10 o'clock.

Peter Kalil: Hi sorry I can't help you with this I've not done the timing myself...

Peter Kalil: Respond to this video...Hi, take a look at the throttle linkage, there is an adjustment that limits the top-end motor speed. You may be able to get some more revs by adjusting it to the end. Also a bigger pitch propeller will get more top speed.

Shawn Michael: The water looks so nice and calm. Where is this? My Yamaha 25HP on a 14ft aluminum, doesn't seem as fast at this. But then again the water is choppy.

Ross A. Loving: I have this exact same motor and am having an issue with timing it. Any help?

masterkent18: damn thats fast! i love mercs

seanelm: Great video, that is a nice classic Mercury. The water is so glassy, looks like a great place to cruise. Thanks for a good vid

corvettels9: that's a damn nice motor.....would you ever sell it?

MegaFicht: i am an evinrudeman,but it is fun,also to me,watching these old merc's looking good and running well.Here in Norway,in the old days,it was almost only to brands,it was evinrude/johnson(omc) and mercury,until all the other things start pouring inn.

SRVoodoo1: That motor is fast. I have a '67 Merc 20hp that looks & runs great.

Peter Kalil: @prostovanka Hi, I guess in 1971 it cost around $600, today 40 years later, I see them around $500-$800 depending on how beat-up they are.

SnipeShot314: @SkimmerTime Thats almost true my dad's 20hp's two worst enemys were salt water and wear and tear.

sabeckie: hi, what size boat is this?

Rocktecho: Wow your boat was really planing

Peter Kalil: Hi Thanks! I got the motor in 1975 and it was always the fastest of the 20's. I went to use it lately and there were electrical, foot oil seal problems etc. So I had it all redone including the carb, coils, points, main engine gasket and o-ring while it was apart. The work was done at Woods & Lakes in Fairfax Vermont, and the work is great a youcan see! The 2 blade prop givs it the top end speed.

lakecrab: I got many years of fun out of my '67 Merc 200. Last time I tried to use it, it would not start. Too lazy to go thru it and get it running again.

aaron baker: what size of boat do you have it on, just wondering cause im putting one on my 13ft. boat

Mike T: @SkimmerTime Yeah ok, sounds good, haha

Owen Nicholson: going that fast, you should back of the throttle a bit, uses way less gas

Peter Kalil: @Motorfordtoyota Thanks I love this motor, the days of the 2-strokes will soon be history, I'm glad that we have been part of it!!!

shawn mccall: what size is that 2 blade prop i love it

chaser5444: So SWEET,Thanks for the ride!

Peter Kalil: @HarborRat13 Hi the prop says 11p A1

Peter Kalil: @Stokkelo Hi, thanks this is in Quebec, Canada

Anssi anon: how mutch gas does that drink in 1 hour in liters?

John Willis: i just picked up a cherry 20 hp with controls for 500.00 this looks new!,wxactly like this one , are the red belt or stripe one hi perf or they just change the graphics?

Peter Kalil: @ShavenNinja Look around the motor for dry and broken wires that need to be repaired. There are some wires under the recoil you could inspect. If you can see spark in both that's great. I always start by checking the tank and hose first for vacuum leaks, or fuel pump. Let me know what you find...

Wyatt Russell: I have a 69 Mercury 200 very similar to this one but I'm having issues with starting it. Many pulls to get it going and when I do the throttle is unresponsive. I can give it gas and it will take several seconds to power up. I'm hoping it's an ignition issue...

ScottAtwater1: That is Fast my Scott Atwater 25 hp goes 25 mph with two people in it in a 14 foot rowboat. Kiekhaefer was a head of everybody back in the day!
