1970's Evinrude 6 HP; Water and Prop Testing

[@jeffmckaig4763]

I have that same black prop on my '77 Evinrude, thought it did pretty well, pushed my 12 Foot Sun Dolphin to almost 9 mph. Great video and prop demo.

[@evinrudej]

Did you notice a difference from the 2 blade prop ?

[@adamvogler5441]

These are by far the best little kickers out there. Pure bliss

[@HighTidesScuba]

I have that same boat ( 1996 Grumman 10') with a Burgundy Bimini top. I'm running a 2006 8hp mercury 4stroke. My wife and I go out to the ocean and fish quite often! Our top speed is 21.6mph

[@mikedurhan9941]

Thank you, Brandon.

[@bennyblanko3]

Oh, and I love your videos!

[@oneselmo]

My son uses a gps app on his cellphone to measure his speed while testing outboard, prop, and motor trim settings.

"Alright...Hole shot time" Says the man with a six horse outboard. Actually, the wake in the last scene where you were going back to the ramp looked pretty good. I am looking for a 15hp for my 12' boat and have not had much success. In the process, I passed up a reasonably priced 6hp thinking it would not have done what I wanted. Now I see I was mistaken and the 6hp would likely have been okay.

[@ct1762]

i have a few motors... 8hp nissan (as fast as an older 9.9 OMC), a couple 6hp, and a couple 15's for sale in RI.

[@peteryeung111]

Depending on load, you'll be happier with a 9.5/9.9. Speaking from my own experience having owned more than 5 six horses. Never looked back after running some 9.5s. Of course, if you can find a great deal for the 6, why not.

RI Outboards Totally agreed.

[@WoodGuy]

Nice little motor, runs really good.

[@danield954]

I use one of those 6 hp motors for a kicker motor for trolling. That little motor can get my 16' boat up to 7MPH via GPS, you were going at least twice that. I found most boats need to go at least 15 MPH to get on plane. When doing comparisons it is good practice to use actual measureables like RPM and speed.

[@captainjerk]

I don't lnow much about boating. Seems like you are pretty comfortable in that boat. Thanx for the vid!

I just got a free 12 Foot aluminum with A '75 Evinrude 6hp. It looks in good condition, 85 psi compression in both cylinders. I'm going to put a new water pump on it before I start it. Fun little summer project.

[@therosses5]

better than my 1980 15hp evinrude! i think it needs a new thermostat and it looks like a real pain to get to! I'd gladly take 7mph. nice job as always!!! love your videos.

[@billythekid5196]

[@ct1762]

it is but not too bad. you can take the head off, and get a newer one on ebay that has the thermostat on the top.

[@therosses5]

@@ct1762 it would be nice to get it moved to the top. not sure I'm confident enough to replace the head. but Brandon has a great video for it. Thank You for the idea. much appreciated!!!!

[@therosses5]

@@billythekid5196 i think it's overheating. goes about 20mph for a minute then dies. most likely thermostat. :-)

[@ct1762]

@@therosses5 well if its overheating badly enough to shut it down, your motor is fried. does it restart after squeezing the bulb? my first thought would be bad fuel pump or dirty carb. put your hand on the head at idle until it warms up. you should be able to put your finger on the top for 3 full seconds without burning yourself (150 degrees). next time squeeze the primer bulb as you get on plane and see if it delays stalling. if it does, get a new fuel pump. if not, pull the choke. if it picks up then dies, its the carb.

[@chuckcecconi8801]

What was the last prop you ran? I just picked up a 1966 mint for $100.00 im setting it up for my kid to learn on.. i love the videos.. You, Johnyrude, old Chrysler outboard dude.. learned a lot from you gentlemen.. thanks

[@Pleipoy]

I have a couple of theere oldies. Best soundin engine. Also have the new updated from 1992 with much more power but I like the older if not in a hurry.

[@bennyblanko3]

wow! $18 to launch?!!! Did 4 girls launch it for you? And give you special gas that makes your boat fly? That seems like a lot of bread!

[@davekimbler2308]

@@joeblan9426 I think that was the public launch ! Lol

[@BrandonsGarage]

There is, the problem is the ramp is 8' from the water when its slightly low. Only really usable late in the evening without 4x4. This ramp was privately owned, but when he died the wife gave the park to the city. City put a pay booth up and have been enjoying the profits.

[@Bigtime_mcalpine]

Thanks for posting Brandon. Quick question for you on this motor: I’m looking to install a telltale and was thinking I could just drill through the exhaust cover on the tiller side of the powerhead…did same on my 9.9 with success but was wondering if you have any thoughts on whether this would work.

[@TopBananaMan]

So which prop was the best?

[@Crodgers88]

I just acquired a 14' job boat with same motor and wide open im barely getting 5.9 mph feels like it hardly getting out of its own way

[@BrandonsGarage]

Yeah, sometimes that's how they are. But with the right prop setup and weight distribution, you can get some enjoyment out of them.

[@jameswaller5568]

Someone suggested to me recently that i "Spun my Prop" Never heard of this before. The Hub i assume. It got me home. Can this be fixed? I'm pretty handy. Avoided? Lighter Shear pin? I cut 2 spares outa 3/16 Brass. Aluminum maybe? I suppose i'd better check the old one with a magnet before i Sh.t-Can it.

[@blueback21]

That’s a lot faster than my Johnson 1968 6 hp I only got 4 1/2 miles out of it on a little inflatable, something must be wrong

[@mikeb6957]

Where are you putting that boat in? Is the Colorado river 6 hp safe! I don't know just asking?

[@BrandonsGarage]

Needles, Jack Smith Marina. On this boat, and one of similar size, the 6 HP can battle the current just fine. When you get under 4 HP, or larger loads, is when problems arise.

[@-Viceroy-]

Tachometer reading would have been interesting to know. Especially with those slipping 2 bladers. Do you know what year the power outlet/battery charging option was introduced in those motors? (i see no place for the outlet plug in that one)

[@ct1762]

i don't believe they ever made one with a charging system. the later models changed in 1980 as a 7.5hp (and in 84' same motor but 6hp at the prop) did have them, definitely for the sail version.

[@BrandonsGarage]

RI is correct, however, 77, 78, and 79 had the CD ignition, you could add a stator to it. With a stator, add a rectifier somewhere, and with that, you now have 12v.

[@-Viceroy-]

@@BrandonsGarage That's weird. I have one late 70's 6hp with a charge coil and an outlet in the side of the lower motor cover (no rectifier. I guess the rectifier comes with some sort of a charging kit/harness). Engine Model No. 69B66E

[@ct1762]

@@-Viceroy- these can get weird model wise! anything is possible , especially with motors made for the overseas market. some oddballs out there. That kit was most likely a retrofit from a later one... unless you are sure its a factory one? Brandon is spot-on: the CD ignition models use the same armature plate 4-60hp of that era, which means it would be easy to add the 5 amp power coils.

[@-Viceroy-]

I'm pretty sure it's all original. I know the previous owner who had it from the new. This one is Made in Belgium. Hard to find anything with that model No.

[@ChippyOZ]

Nice comparison Brandon. My 79 6hp has a 8.25x8 3 blade but it is stuck on the shaft and I can't remove it! Any tips on how to get it off? Don't really want to get stuck on the water with a broken shear pin and not be able to replace it and get going again... thanks.

[@davekimbler2308]

Lots of PB Blaster and a steering wheel puller on a 2 blade and a balancer puller on a 3 blade !

[@BrandonsGarage]

Agreed. Also, if it does spin and break the pin, means the prop has broken loose and will come of! More likely you'll spin the prop hub though.

[@ChippyOZ]

@@BrandonsGarage Ahh of course, didn't think of that occurring ... Time to get a puller on it and hopefully get it off. Thanks!

[@ct1762]

@@davekimbler2308 yes good tip. i've also cut into the prop and used a split bearing puller. bye bye prop but grabbed another from the pile!

[@ChippyOZ]

Found a puller but was unable to secure it to the front of the prop hub or blades. So positioned the outboard horizontally with the prop facing upwards, sprayed a rust breaker all around the prop shaft to soak in, used a propane torch to heat up the prop shaft a bit to get the juices flowing, held up the weight of the outboard by holding onto the prop and hit the end of the prop shaft dead on with a hammer. It started to move very slowly after a few strikes and then continued on carefully until it fully came off. Prop shaft had some rust and pitting and the inside of the prop hub had corrosion. Cleaned it all up and slid back together nicely with some triple guard. Not sure if it was the best way to do it but was all I could manage.

[@mrJay-hg6ep]

I have a 1971 6 hp Johnny, going to use it on 1982 harbercraft classic 12' So what is the best prop?

[@mrJay-hg6ep]

Also can you disconnect fuel line from the tank instead of motor to use up fuel in line and carb?

[@BrandonsGarage]

@@mrJay-hg6ep Doubtflu, as the hose will usually have that spring loaded valve to shut off flow when its not plugged in; thus it wont be able to suck anything out.

[@smithantiqueoutboards]

@@mrJay-hg6ep Really late, I know, but what I do to drain the line is hook the motor end up to the tank and just squeeze the fuel back into the tank.

Sadly its rather hard to find. eBay is your only real option. Which sucks too, as I think its the best prop for these little 6's. (I already knew this going into the video)

[@outboardfun3353]

How about raising motor

[@rrrttt1112]

add some shims under the motor on top of the transsom to get the cavitation plate higher in the water, to increase RPM and speed.

I have an old 1969 Sears 12 foot. I use a 3 Evinrude or 6 Johnson depending. I always want to put a Bimini top on it. I probably could but it would be for a calm day anchored. Running with the wrong gust it would roll the boat over.
