This brought back some good memories. My first boat had a 1986 Evinrude 70 on it. It was very reliable to say the least and we never had trouble pulling a skier. Even slalom skiing was possible, since the boat was very lightweight.
I love these old 2 stroke outboard motors from omc they're awesome and last forever these motors are bullet proof I always wonder what they would have done they never went out of business they're really doing some awesome things in there last year's engine blocks with v4 v6 and v8 seem alot easier to work on and modified
So strange, we have a 1989, 60 hp OMC/Johnson (i.e. you'd think they would be very similar) yet yours sounds nothing like ours at all! Your power up at 23 seconds is truly spectacular whereas ours sounds kind of boring and flat.
i have a 16 alumacraft with a 50hp. i can easily do 38mph on a calm day by myself. Average around 35mph. i want to throw a 70-75 on mine too. i bet it will go up at least another 10-15mph.
These were some of the best engines built by any manufacturer, they did everything well. Good on fuel, amazingly powerful, simple, rugged and reliable
Excellent work if that’s a rebuild, probably the most user friendly 2 stroke outboard I’ve seen😊

What an awesome video. You really got that Evinrude singing. Great job👍👍👍
Glad you liked it!
I have a 1982 Evinrude 70hp in about the same shape. Lovely motor.
top speed?
@danielbennet8863 about 35mph with a 15ft fiberglass tri-hull (1984 MFB Gypsy)
Nice work Con, controlled it perfectly and she sounded awesome from start to finish
Glad you enjoyed it

As a outboard mechanic on new stuff, old is better than new dont but new Outboards.
What a motor!
i have an 87 70 evinrude what a beast but sometimes there is a bit of steam coming from the rear relief ports.. for the rest solid motor
So cool
Great motors I owned one for a few years.
They start every time.
Even the cover looks brand New
Indeed, it has been looked after
lol... god damn, watch that thing crank to starboard when you hit it and that starboard cable going slack. 🤣

Check cylinder compression
super job super motor
She runs like a charm.,
70HP Evinrude was a 3-cyl engine made by Triumph (motorcycles)?
Not made by triumph, made by OMC/Evinrude/Johnson. Triumph was just the model name
What was your top speed with this set up? I have a 16 foot river boat I was thinking about throwing a 70 on. I bet it would haul ass.

Nice! Could she handle a bit more prop pitch?
no. if anything a smidge less pitch. these really need to be at 6000rpm at wide open with a light load.
Have an 82 evinrude 15hp starts right up
Goes very fast but needs a turbo haha
hang on to that, a new 70 is 9-10k and virtually unserviceable by anyone without specialized tools.
Oh yeah!
920 cc or 849cc..??
