Hydrostream Viper.. Mercury inline6

My viper ripping down the James river

[@TheSoloAsylum]

I think those Merc inline 6's were some of the best outboards ever made.

[@PLAYBOYNOCOOLANT]

I am currently rebuilding my fathers '76. God bless them.

[@D7mSupra]

They are the best ever made

[@jeffb8562]

Yes they were. And I have no idea why I ever sold mine. Had it on the back of a 22 foot invader deep V hull. Seated six people comfortably and still did 45 to 50 mph.

[@izaak997]

I have a 1985 cruise craft rouge 14ft with a 90hp mercury inline 6 2-stroke. We take it out every opportunity we get, never had a single issue. With a bit of TLC these things will last a lifetime, plus you can't beat that sound on WOT 👌

[@russb959]

Amazing motor’s probably the best of it time! Mercury was and always will be ahead of the times!

[@justinkeckhaver8199]

I grew up and fished in a 1975 Savage bass boat with my Granddad. Had the same 115 Merc. Man, there's not a better sound in the world than that old "tower of power".

[@RC-sj6zi]

There's only 3 outboards that give me chills by the sound alone and these plus the 140 johnnyrude and the 300 v8 johnnyrude.

I had a Vector with a 130 Yamaha. It ran best with a Mercury Inline prop. 26" chopper. Special props made just for that motor. I had similar performance to this boat. Mid 70s.

[@Rlip]

I have a 1962 merc 85hp straight 6 I’m restoring, awesome engines. I think the years with a regular magneto/distributor are the best engines. Don’t have to worry about the common red stator failures or a power pack. I blew a couple up and rebuilt them really easy, used a butter knife as a ring compressor, tricky with 6 pistons 😂. I’d love to have a tunnel hull with 2 or one of those 2 stroke v8 Evinrudes…. ❤

[@_CAT-lg4sr]

I remember (many moons ago) reading about Johnson outboard's prototype of a Wankel four rotor outboard. it put out something like 320+ HP and being a Wankel, it could rev to something in the neighborhood of 10,000 - 12,000 RPM. The trouble was it kept ripping the transoms right off the back of the test boats used back in the 1970's

[@312maxon]

I've watched your run a couple times to see what to expect from a 1980 Hydrostream Vector w/ a Mercury 140 inline 6. (2 more feet of hull, a bit more weight, offset by slightly more power at slightly higher RPM.) I've only been out once so far, for a measly hour before dusk, on a lake w/ a 40mph speed limit, but I'm already hooked on these beautiful and capable little monsters. Thanks for showing off your sweet black Viper & "tower of power". Dual steering cable retrofit straightforward / worthwhile?

[@D7mSupra]

I can get more out of it.. the motor was lower and I had a 250 lb passenger during this run

[@pjimmbojimmbo1990]

A 140 inline 6 is crank rated, the engine in the Video is a Prop rated 115. The is only about 2 or 3 HP difference between the 2

[@kita508]

1982 Tower of Power were awesome engines, I have one on my Procraft never had any problems with it in 20 years. Only cons is gasoline mileage. Buy Super Engines.

[@biasbilt]

A thing of beauty, especially when you trimmed up at 4.50. Nice going!

[@kevinbushey1879]

Sweet very nice rock on.

[@davidweigel2238]

Nostalgia for sure, but the new Mercury V8 4 strokes are something else. Throaty, fast and fuel efficient.

[@prevost8686]

And they will still never match the simplistic design and reliable power of a 2 - stroke. Obviously if I were running an offshore charter I’d run 4-strokes to obtain the quiet and efficient operation they offer but for my personal use , after owning one 4-stroke, I’ll keep my 2-strokes.

[@gerardpronk2163]

I had this motor on a malibu mark 2.Nothing could touch it 98 kmper hour .back in 70 s

[@pjimmbojimmbo1990]

Based on the transom bracket the engine is post 1983, the cowl wrap is from a 76 or 77, the Front and top cover are post 1980. It is either a 90 or 115

[@D7mSupra]

[@kalaharimine]

@@christopherhampson265 It is high because it looks like he's using a SS Chopper prop, ideally that's how you get less drag and max performance.

I've got a 89' 115 Mercury on a 17'5 Venture Vendetta. I went over it and installed, new everything (cosmetically speaking). Never been in the water. That boat weighs less than a half ton. Think it'll push it alright ? How fast will it push your rig and how big is your set up ? Also, I've heard that these are actually pretty descent engines. What's your opinion, are they ? Where would you rank it on a scale of 1 to 10 (btw, I mix oil in gas, took oil injection off). If I encounter a problem w/ the lower unit, I'll replace it. I like the sound of a 2-Stroke and their lighter so more power and less wait.

[@D7mSupra]

The adi 115 has higher porting than a normal 115

[@havocsquad1]

That motor is threading the limit of how high that height adjustment is placed. The motor needs to probably come down at least 1 inch with that adjustable transom plate. If you see when poor water conditions hit the boat, the anti-cavitation plate is out of the water and the prop is losing grip.

[@D7mSupra]

It has a 14.5 diameter prop stainless chopper.. it had a lwp.. I know what I'm doing

[@D7mSupra]

Set up for speed

[@quickturn66]

The setup is near perfect,there is plenty of load on the motor,he’s running a surface piercing prop,more lower unit in the water equals more drag. Jacking the motor and using more pitch is the recipe for speed.

[@byknutz]

@@D7mSupra needs more grip? HahahH. Dude you have that thin diialed! What is the pitch on the prop? So its a 4 blade? I have a fresh 1500 powered head we rebuilt a while back, im gonna start putting the whole thing together this week. I have the 650 on my boat now. Its a 73 Bayliner Mutiny 16'

[@tommywatterson5276]

Probably the most powerful outboards made for hp, torque, and speed. The inline sixes are better engines over the V models.

If I could get one to push me 90mph then I would agree.. still very well engineered.. they paved the way for the v6

Love the video , that engine is awesome, love the tower of power mercs and the prop looks vicious , just wondering though if you dropped the engine down six inches would that increase the torque ? It's been years ago but my old 90 hp six cylinder Mercury had a twin blade speed prop on it and it sat up high but when I dropped it down about five inches the torque difference was really noticable and it didn't seem to effect top speed any

Too much motor for your transom. Watch close when you hit the gas, the foot of the motor goes toward the transom, and the transom makes sounds like if you keep doing it , you’ll ruin the transom and possibly sink.

That's not the transom, it's motor mounts. Factory hydrostream transoms will run a 200+ with 6 inches of set back for years.
