I've just fired up the 77 70hp Evinrude that came on a 68 Currituck but don't see a '[vulgar language deleted]' stream coming out? Not even an outlet that I can find.

Water is mixed w/the exhaust at the prop and up higher at the dual exhaust outlet.

I need reassurance!! (and advice)

A friend of mine has a 1978 Evinrude 70 HP...

His tell tale stream outlet is located on the lower right side of the cowling in the rear. Take off your upper cowling and look to see if there is a Black hose attached to a plastic outlet in the location above..

Many times the hose or the outlet gets clogged up. You can take the hose loose on the engine end and see if you can blow through it. If not, run an air compressor or small wire through the hose and/or the outlet fitting to clear it...

My 1985 Evinrude 70 HP is setup exactly the same way...

My 88 Evi 90hp has the outlet there. The manual also shows that point as an outlet for the 70 too, but absolutely NO outlet! No hoses. Weird!

I get a strong spit of water if I rev a bit coming from the rear dual exhaust but it's sporadic.

I guess I can't help you...

The 1977 series, or your particular engine, does not seem to have the tell tale stream in the same location as later models or??

Someone else here should be able to tell you.

Good Luck

I think that the 1977 model year was the first year for the telltale. If that 77 70hp Evinrude was made early in the production run, it may not have one. My 1977 35hp Evinrude had a telltale that was directed straight down because the engine pan was an early 1977 production run before they modified it to angle the telltale stream.

Also, are you sure it is a 1977?

Maybe it's a very early production 77.

Anyone have info on a 'pre-tell tale' model?

Oddly enough, the guy I bought the boat from included a new impeller? Maybe he had diagnosed it and then forgot to let on that it needed replacing?

At any rate, I need to know if I'm gonna see it [vulgar language deleted] when it's running!

My father has an Evinrude 70 of right about the same vintage that does not have a telltale. Hate it in the Louisiana mud. It's really a pain to walk to the transom and put your had in front of the exhaust to make sure cooling water is getting through. He ended up putting a temp guage on it. I believe his mechanic convinced him this was the only reasonbly priced option. By the way, that engine will not die. I think its outlived one non whaler already.

Good Luck

Thanks for the confirmation! I'll probably go ahead and replace the impeller anyway AND add a temp gauge. It has a warning light installed next to the key now, but unsure if it works. Also, has the overheat buzzer.

I've heard that these 3 cyl. Evis are bullet proof!
