Yeah, much looked good before I started touching things and the insulation started crumbling off the green corroded wires. 😁 . I'll definitely be going through all the wiring and making repairs before I attempt to start it. Same with the whole fuel system. .

I have a 1978 Mercury 700. 130+/- compression. I have spark on 1 and 3. I have no spark on cylinder 2. . I'm sure there are several methods of process of elimination. . Here's what I'm thinking. Let me know if this sounds right Test 1 If there is Spark on 1 and No Spark on 2, swap the two...

Using Google Translate: . Usando el Traductor de Google. . No deberías intentar superar las 5750 rpm. Podrías arruinar el motor.

Lower unit oil must have been typical gear oil and not marine gear oil, because about a half a teaspoon of clear water came out when I removed the plug. Oil was black. The plug has a magnetic tip, but I didn't find any metal shavings on it or in the oil. . I haven't started working on it yet. I...

Yeah, we go to a place in Astoria called Buoy 10. It's a blast of a fishing opportunity, but need at least 12 gallons a day if we want to always be where the fish are at any given time of the tide cycle. I want around a 20 gallon.

I'm just posting an update. I've been enjoying my StarCraft. Perfect beater for my interests. The Suzuki I had on it went out in around June and I shopped for a used replacement. Knowing how hard it's been finding parts for the 84 Suzuki, I did some research. I asked myself, why isn't there a...

Much of those pieces fell off when I had to break the blocks in half to get them out of the 30" hole I cut. The larger styrofoam blocks are solid. But yes, a project down the road would be to pull it all up and replace it. .

I'm learning. 😊

Yeah, it just seems easier to temporarily move one wire than to move the coils. I'd put things back of course. But if when I do that, and #2 then has spark, I know it's not a bad coil.

Rather than taking the coils out to swap them, I could just temporarily move the green wire from #1 to #2 to verify if #2 coil is good, correct?

I have two on my v4. But that makes math sense. 😊

Yeah, my research is telling me this same lower unit is used all the way down to a 30hp. And the 70hp was the biggest motor they used this lower unit on. It does look really small. . Google keeps giving me different answers for this motors weight. Sometimes it says 250 or so, sometimes it says...

Yeah, I keep my boat out of the weather. The floor is sturdy and dry. Surprisingly, (knock on aluminum) I haven't found any leaking revits. After I rebuilt the transom 4 or 5 years ago, every time I took it out, not even a drop of water in the bilge. This last four day trip was in semi rough...

Yeah, but it needs 1.21 gigawatts to work.

Yes, I took lots of pictures as I removed things. It screwed into the bottom of the cover that was over the carbs.

I bought this: ...

Thanks, I'll look further into it this winter. I need to get back to more pressing projects. I mainly wanted to verify the motor had good compression to know if I should just part it out or not. But I'll give it a chance to live again. 😊

Some stinky old fuel in the carbs. And the hoses look original. I'll need to clean up some corroded wiring and clean the carbs, and run all new fuel lines. But like I said, I'll make it a winter project. But at least I know it's worth getting it running.

139, 137, 135. Spark jumps a 1/2 inch gap on 1 & 3. No spark on #2. No spark even at coil of #2. . Really funky build for getting to the carburetors, but I guess it's worth getting it to run. . I'll be putting it away for now and perhaps make it a winter project.

When I go to Crowley Marine or Boats dot net, I see a lot more parts availability for Johnson/Evinrude 70's 70hp, than for this Mercury.
