    Mercruiser MC-1 Hydraulic Ram Hose Leaking

    Hello, I have a pretty major leak on my pre-alpha (MC-1) tilt ram hose. Ram works fine, but I'm concerned about this hose. Normally I'd just replace the hose, but I can't quite figure out how the hose attaches to the ram. One of the hoses just screws in like normal, but the other one looks like...

    Received a Ray Jefferson 5000M Marine Radio, but don't know how to use it?

    Thanks, all! @dwco5051 That VHF basics article was exactly what I was looking for. @dingbat yes, it looks and feels old :) It seems to spin through ~85 (give or take, I forget exactly how many) channels, but seeing as how I'm wanting it for safety reasons, I'm concerned that it doesn't have a...

    Received a Ray Jefferson 5000M Marine Radio, but don't know how to use it?

    Hello all, I recently received a Ray Jefferson 5000M Marine Radio. I have never had a radio in the past (I'm mostly in a lake or a small bay), but I feel like it would be really good to have and know how to use. I got it hooked up to my battery and it turns on and everything, but I just don't...

    switching out lower unit on Mercruiser MC-1 - what to look for?

    ok, I see, thanks. Any downside to testing with the prop I have now (just like 30 seconds at WOT) to see where I'm at? Or is even 30 seconds at WOT damaging? It would be ~5 min at slow speed to get out of the harbor, then ~1 min at medium speed to get out a bit, and then 30 seconds at WOT...

    switching out lower unit on Mercruiser MC-1 - what to look for?

    Thanks for all the info! Just a quick beginner question. When you say that shifting issues are almost never due to a drive problem, what are they due to? I kind of thought that the shifting on these was pretty simple... you have a cable that goes from your shifter, to a linkage at the engine...

    switching out lower unit on Mercruiser MC-1 - what to look for?

    thanks. So just a few absolute basic questions here: 1) just confirming, this is true if I'm switching out the whole outdrive, right? Not just the lower unit as my post erroneously stated? 2) what does the 1.65 and 1.98 mean? Not sure what those numbers refer to. Old is 1.65... what? Is...

    switching out lower unit on Mercruiser MC-1 - what to look for?

    Not 100% sure, something is up with the shifting. Figured I'd buy another so I can still boat around while I'm digging into this one... I'll likely rebuild the whole outdrive. Important note: I have no idea why I typed "lower unit," I think I was looking at lower units while I was typing and...

    switching out lower unit on Mercruiser MC-1 - what to look for?

    Hello, I have an old but decent MC-1 on a GM inline 6 / 165hp. Swapping out the lower unit and a friend has an MC-1 lower unit in good shape. Problem is, it say on there it's for 120/140 mercruisers. What's the difference between the lower unit on a 120/140 and a 165? Could I use this lower...

    Anyone know anything about Corvair(?) or maybe Traveler boats?

    Hello, I recently picked up an old (1960s) aluminum dinghy-type boat. Title says "Traveler" and the side says "Corvair" (see image: https://ibb.co/sKWNkVv). Not such which of these would be the manufacturer, or one might be the model or something? Couldn't find anything on the internet or in...

    Any way to definitively tell between a johnson 9.9 and johnson 15 hp outboard?

    Ah yeah that's really helpful, thanks. If/when I need to get down to the carb I'll use that as a comparison. Thanks

    Any way to definitively tell between a johnson 9.9 and johnson 15 hp outboard?

    Thanks. I may have to dig deeper to get to the carb and measure the throat or needle, but maybe these photos will help: https://ibb.co/zsKCr1x https://ibb.co/rvr40RY plate says that the model number is: J15RESR Thanks

    Any way to definitively tell between a johnson 9.9 and johnson 15 hp outboard?

    Hello, I bought a used johnson outboard. The cowl cover says 9.9, and the manual it came with is from a 9.9, but the model number on the nameplate lists it as a 15. And, the nameplate looks way newer than the rest of the engine. Just curious—is there any way to absolutely differentiate between...

    what are these trailer bunk brackets called?

    Hello, I am in the process of fixing my trailer. It's kind of a bizarre trailer... it's missing basic stuff like cross members, etc. Part of why it's so odd is that it has the bunk brackets mounted right to the frame, instead of on the cross members. Some of the brackets are rusty, so I'd...

    Testing and maybe Reviving dead/low Deep Cycle Marine Battery?

    Hello, My trailer has been having issues, which means I haven't used my boat in like a year.... just tried to give it a start to make sure everything is still all good and I think (both) batteries are dead or low. Light, blower, trim, etc all work, but when I try to crank the motor, the...

    basic beginner questions about boat trailers (specifically with aluminum boats)

    OK, first photo... here's the current setup. Hard to see, but the bunks go from about 2" behind the transom (need to lengthen the bunks) to about where the red line is: As you can see, the front of the boat is totally unsupported. So my plan is to add in two (one on each side) 8-foot 2x6s...

    basic beginner questions about boat trailers (specifically with aluminum boats)

    hello all, I am realizing that I need to start thinking about replacing some parts of my trailer, and I've never really thought about my trailer too much until now. So I have some basic questions, hopefully someone can get me pointed in the right direction! 1) just a general question about...

    Avon Valves—what kind? Need an adapter

    Hello all, I recently bought an Avon Supersport S4-60 inflatable. It has a few valves on it, but I can't for the life of me figure out what kind of valves they are. I've bought 2 different foot pumps, and they both came with adapters that said that they fit Avons and neither of them seem to...

    new to inboards—a few questions!

    Hello, I recently bought my first boat (1970 starcraft islander, i believe the motor is a pre-alpha mercruiser 165) and I have two questions about I/O engines. (okay, not super recently, but I've been fixing other stuff and haven't had it in the water yet :/) I've really only had outboards up...

    Mercruiser MC-1 (pre-alpha): new shift cable? DIY job?

    Hello, I have a mercruiser 165 with a MC-1 (pre alpha) outdrive. I had a mechanic change the bellows, which he did, but then he needed to get a new shift cable. Now he says that the old shift cable was a slightly different style, and he needs to "drill and tap out" part of the outdrive to...
