    Add telltale pee hole to 1965 Johnson 75 HP

    It's not going to happen on the cheap. Achieving a failsafe design with no single point faults puts the application into the realm of personnel safety circuits with monitoring, diversity, and pre-emptive fault detection. To get something at least plausibly unlikely to fail simultaneously that...

    I hadn't noticed. 🙄 Thanks...I guess. I would have used a 12V marine warning buzzer. In fact, I did. No lectures about control logic, please; I'm an electrical engineer. If there's a fault in the incandescent light, i.e. an open circuit, there's nothing to detect it in the quiescent state...

    Yeah, I'm a EE so I'm well aware of the cheap piezo peepers, but I wanted to find something high-quality and plausibly OEM. This device enclosure is rated IP50, which still isn't water resistant (another reason to put it under the dash), but at least it is a dedicated-purpose piece of marine...

    Following up. Rather than adding a telltale, as suggested I'm adding an audible alarm. I found a nice 12V stainless steel marine buzzer with an 18mm round body. Rather than drill a hole through the boat's vintage dash, I bought an stainless steel 18mm industrial proximity sensor bracket. I'll...

    1964 Cherokee boat decals does know how to find them

    That's hilarious! Couldn't do that again if you tried, lol. Looks like pop art. Maybe try again, but cover it with another sheet of clear adhesive film that's 1/4" larger in all dimensions.

    1958 to 1968 V4 Special Tools

    Excellent tips, thank you! You’re right, maybe it will come right out! It’s just an O-ring and maybe it’s not even very tight anymore. Appreciate your insights.

    1958 to 1968 V4 Special Tools

    I have the 1965 Johnson Outboard Service Manual, P/N 312468. I believe it's a 1990s reprint from Helm, Inc. The manual says that Special Tools are listed in Section 15, but the book stops at Section 14. My engine is a 75HP electric shift. Here's the last page of Section 14. Looks like there's...

    Oh, sorry 'flipped" as in sold it quickly! The old runabouts are a little scary sometimes when the water gets rough. My dad took us out into the Chesapeake Bay one time to the New Point Comfort lighthouse. It was fine on the way out but on the way back we had two-foot seas and it was pretty...

    Flipping a boat sounds like a very bad day! Great styling on the Johnsons and Evinrudes of those years! I remember thinking as a kid that the Evinrudes were the futuristic Space Age and the Johnsons were the "white hats" compared to the Mercury "black hats". I ran across an NOS front emblem...

    Love these! I have not seen those ads! The old ads really were so happy & upbeat, weren't they? Thanks for sharing! I have a 90 HP Golden Meteor in pieces that I bought for spares probably around 2000; cosmetically rough. I never used any spares from it, so might make a nice project to put...

    Oh, that's great news about the NOS lower unit oil! It's fully sealed in the plastic tubes that you cut off and squirt up into the lower fill hole. Thanks! It's OK, I'm a veteran of many varieties of enthusiast forums since the days of internet bulletin boards. Every forum has a culture; some...

    Not boasting about it really, just stating what is. I said it’s been living on borrowed time & I’m preparing to address it. Thank you for the info about the availability of new temp switches & correct electric shift gear oil. I bought a case of the correct type 25 years ago when it looked like...

    Nobody asked for an iPhone or broadband internet back in 1968 either, but now it’s 2023! 😃

    Add telltale pee hole to 1965 Johnson 75 HP

    Your veiled insult to my mechanical knowledge notwithstanding, most people never heard of a telltale back before they were installed on new motors, so your point is a non-point. Someone made the comment that a telltale out the back is useless because you can’t see it from the helm (although I...

    @Crosbyman Appreciate your observation! I moved the winch strap pylon 1-1/2” sternward from its original location to get the whole transom on the rollers. The starboard side has a little more aft overhang than the port side. Boat is centered and the rollers aren’t adjustable fore-aft, so perhaps...

    It was delivered from the Glasspar factory in Petersburg, Virginia like that, so I’d say yes. Thanks for the insights, everyone.

    Yes, I saw that mentioned in the old post as OMC's original approach...not optimal, since that location was before the head or block and being down low, where air could be introduced. I'm thinking that the vestigial hot water choke port would make more sense being that it's in the block and at...

    That line of reasoning begs the question of why OMC added them to later models of the same basic engine.
