    eBay wants $24 used. Boats.net wants $24 new. Hmm.... What should I do? 😊

    Stuck Steering

    Yep, I gave up. It was just way too corroded. The thing is still stuck solid in there.

    1978 Mercury 70hp Worth Messing With?

    Sorry, yes, I should have known that. It's similar to my Johnson 90 having the same ci as the 115.

    1978 Mercury 70hp Worth Messing With?

    I will be putting in a new impeller. I was only mentioning it's softness as possible evidence someone had been in there in the recent past. But yes, it needs replacing.

    1978 Mercury 70hp Worth Messing With?

    Also, I watched a video where a guy said this really is just a 50hp with carburetion and timing advanced (RPM) to get 70hp. . Interesting, Shop Manual shows the same Cubic Inch from 50hp to 70hp.

    1978 Mercury 70hp Worth Messing With?

    Yes, they are pretty scary looking. However, they are just really significant scrapes. Scraping of the metal itself. Fortunately they haven't deformed the housing itself. . I attempted a vacuum leak down test on the lower unit after work today. I couldn't get it to develop any vacuum resistance...

    Sierra Marine Warranty

    I see people post often to go with Sierra Marine because they have a "Lifetime Warranty". . Has anyone ever had to do a warranty return on their Sierra Marine part? . Sierra Marine says to return it to the seller, and the seller applies for the return authorization. . I can imagine how that...

    1978 Mercury 70hp Worth Messing With?

    The way the wires are crumbling as I remove them, including the wires coming from the stator, I plan on rebuilding the whole harness - all wiring - every wire and connection.

    Stuck Steering

    I'll get a picture tomorrow, but I've got it out about 2 inches so far, and it's really corroded - black rusty crap. I'll leave it be for now, but I'll be watching marketplace for a good used replacement.

    Thanks, I bought a physical service/shop manual.

    1978 Mercury 70hp Worth Messing With?

    Yeah, I was only mentioning the impeller's softness for verification that someone had been in there not too long ago.

    1978 Mercury 70hp Worth Messing With?

    I'm reading the motor is actually only a little over 60hp at the prop. But yeah, I just took it off. It's a little light one. :) . It's on a 1978 15 foot Britton BeachCraft Trihull. . I think it being as light as it is - the whole motor being around 190, I think it'll be an advantage for me...

    Thanks, I'll check for mushrooms, and if, I'll grind the mushroom down.

    Ignition Troubleshooting - 1978 700

    Would I have better chances of success with Sierra Marine? I'm thinking they at least have a lifetime warranty.

    Ignition Troubleshooting - 1978 700

    Okay, switching green wires around from a known good circuit/switch on the switchbox, I get spark with all three coils. And alternating the Violet, White, and Brown Trigger Wires, connecting them to a known good circuit/switch on the SwitchBox, I get spark with any of those three Trigger...

    I got it to pull out about an inch. I'm going to let it soak a couple days.

    Stuck Steering

    Just an idea. Maybe others had thought of something similar. In my searching the forums, I hadn't seen this as a suggested fix for a stuck steering shaft - the shaft that the steering rod passes through - properly known as the steering tilt tube. . I wrapped them with clear tubing so the PB...
