    Water when pulling stern drive

    I have no idea if mine is the old style or not. I’ll be able to look at it this Friday. Thanks!

    Water when pulling stern drive

    Rick, When you mentioned a leak in the shifter pocket, which parts are you referring to? Are you thinking parts 7, 8, and 9? (23-814308, 26-45587, 23-805041A2)

    1973 Mercruiser 165hp and MR drive factory parts manual?

    Hi guys, A couple of years back, somebody gave me a link for those 2 manuals. I lost the links. Anybody have the links for those so I can save them in my new computer? Thanks

    Water when pulling stern drive

    Lou, it came out looking dirty but not rust colored. It was about 10 drops of water that squeezed out ahead of the grease in each ujoint. About the same amount of water squeezed out of the gimbal bearing when I hit it with the grease gun. The joints externally have a nice patina to...

    Water when pulling stern drive

    Rick, Some water droplets squeezed out of the joints when I hooked up my grease gun. I do have a drive jack (now) but I have never glued the big o ring. I will do that this spring when I reinstall the drive. Think I need new u joints and gimbal bearing? In my Mercruiser manual...

    Water when pulling stern drive

    Rick, it was not a lot of water that came out. A few ounces. There was water in the main bellows that I soaked up with a towel. It streamed out lightly the moment I broke the bell housing gasket. Since I have never experienced this issue before, I am unsure as to whether the bellows...

    Water when pulling stern drive

    So I winterized my boat and as I was pulling the stern drive, water immediately poured out after I cracked the seal. The bellows look good (I did them a few years ago). The thing that caught my eye was the large round rubber O ring that goes over the ujoint. Assuming the leak was...

    MC-1 Back Together, Temp 175 Fahrenheit?

    Dave, that impeller looks like it was run dry. Did you apply liberal amounts of marine grease inside the housing before installing the impeller?

    MC-1 Back Together, Temp 175 Fahrenheit?

    Dave, did you buy a pair of the Quicksilver muffs yet? if not, it is a relatively cheap way to rule out the muffs as the reason you are overheating. My boat with the MC-1 drive had overheated. Some of the plastics were visibly melted like candle wax and others distorted yet the water...

    MC-1 Back Together, Temp 175 Fahrenheit?

    Are you using Quicksilver muffs? If not, try them first or as somebody else suggested, run the boat in the lake. With those rectangular muffs, my boat ran hot in the driveway. The Quicksilver muffs are expensive but the boat ran at normal temp indefinitely with them. What...

    MC2 what will replace it

    Why not just buy a used pressure tested MC-1 drive? They are available.

    Recommended fuel for 1973 inline 6

    The boat is running like brand new but one thing has always bothered me since I got it a few years ago (for free…😂. Yeah, right…😩). There is a placard that states “Leaded fuel required. Minimum 93 octane research method”. The engine is a 1973 Mercruiser 250 ci inline 6. All I...

    Mercruiser 165 I6 Exhaust flapper removal?

    The gasket is very affordable. I think I got a 2 pack for $10. You ordered the correct part number. The gasket for the elbow is Mercruiser 27-52076. If the water shutter is original, it will likely be riveted in. I used a hammer and chisel to get the rivets out and then I replaced...

    Mercruiser 165 I6 Exhaust flapper removal?

    What part number did you order? Yes, the area it sits in is round. You insert it partially collapsed so that water back pressure forces it shut. The easiest way I have found to replace the water shutter is to remove the upper exhaust bellows and the exhaust elbow. The rubber of the...

    1973 Mercruiser Sterndrive hinge pin question

    Turn the steering wheel. If that isn’t your issue, just get a sharp tool to raise the nail head off the housing and then you will be able to get a pry bar or hammer on it.

    Which rear nav light position do I use?

    So I did some more investigation. It looks like my boat was outfitted with the old school style lighting as it has a stern light on the back of the hull. The bulb was burned out and I simply did not realize that that was supposed to light up. I figured it was a swim platform light...

    Pre-Alpha Visual Identification Resources

    I bought just the upper gear case for $170 shipped. The gimbal housing cost me $120 shipped. Both of those were from ebay but the salvage yard listing those items was in Wisconsin. The reputable salvage yards all have online reviews. The eBay listings from the salvage yards...

    Pre-Alpha Visual Identification Resources

    I bought a pressure tested MC-1 for about $250 shipped. $850 is insane. Use a search engine and type in “MC-1 sterndrive for sale”. Lots of boat salvage yards will pop up with variants of that search. Also, check Facebook marketplace. My drive came out of a boat salvage yard in...

    Which rear nav light position do I use?

    https://www.uscgboating.org/images/420.PDF I didn’t realize boating was covered under CFR just like flying. Both of my licensed neighbors were correct. One just happened to have a large boat. Thanks for the info!
