    Bravo 3 stern drive Exhaust Bellows and Trim fluid question

    Posting for a buddy - he has a 1997 Bravo 3 DP on his Jubillee deck boat. The power trim fluid is low and he doesn't know what kind of fluid is in there now (I told him to get a turkey baster and glass jar and see what color it is.) Assuming it's not ATF, he's going to put in Quicksilver Power...

    Where online to find outdrive manual for SX-M?

    The link in the stickies (and other posts) to the boat.info site no longer works. I also found a link to Scribd but am hoping not to pay for a manual. I'm trying to get the workshop manual for an SX-M outdrive. Anybody got a good link?

    General question about Volvo outdrives

    After I pulled my sterndrive to replace the bellows (first time I had ever done this) - it got me to thinking - can water get in to the u-joint bellows while the boat is in the water? There is no gasket that holds the stern drive to the pivot joint; just the 6 bolts and then an o-ring around...

    Grease for the prop shaft? Does it matter?

    2004 SX-M single prop. Been using the volvo grease the manual calls for but the stuff is super expensive. I have some Quicksilver Extreme Grease (used on the drive shaft splines) and it's the same cost but I get about 10 times as much. Is this ok to put on the prop splines? Also debated just...

    Help with trim sending unit adjustment

    2004 SX-M. After replacing the bellows today I went for a lake test and my trim gauge is not working correctly. Once the drive is fully trimmed down, the needle on the gauge shoots past "up". Other than that, the gauge seems to be working. I've read the sticky no less than a dozen times and...

    OEM Volvo Oil Filter numbers interpretation

    Changed the oil on my 4.3 this weekend. First time I've done it myself. The filter I pulled off had numbers on the bottom, and I was trying to figure out what they meant. Seems it may be the manufacture date, but can't be sure. And, if it is the manufacture date, looks like the filter was 8...

    Moly grease substitute?

    Getting ready to replace the bellows on my 2004 SX-M. In the shop manual, it says when replacing the sterndrive, to "lubricate the driveshaft splines with Molybdenum Trioxide (Moly) grease. I have the volvo grease for the splines on the prop, but can't really find molybdenum trioxide grease...

    LED Strip basics?

    Looking at some of the LED strip lighting available now and thinking about running some in my boat under the side cushions, but I don't know a lot about the wiring. Best I can tell, you can buy a roll of lights - multi color (being told to go with 50/50), cut them in certain spots, solder 18/4...

    Random question - are the u-joint bellows a sealed system?

    Out of curiosity - are the u-joint bellows designed so that NO water at all gets in? Specifically, I have a SX-M and am was wondering if they outdrive is designed for no water to get in. Only reason I was thinking about it was because the gimbal bearing calls for the same grease as the trailer...

    Replacing anodes on a SX-M

    2004 Hurricane with a 4.3 volvo and SX-M outdrive. Friend replaced his anodes on his mercruiser and that got me thinking about mine. Are they even external? I found one site with a schematic but can't tell. Do I have to pull the lower unit to replace them? Boat has never been in salt water...

    Cutting fiberglass for a speaker - will it affect the structural integrity of boat?

    So the wife wants to be able to hear her music (better than currently) while lounging in the water behind the boat. I'm exploring some mounts for the bimini but it most likely won't work. Other option is to cut a hole on the back portion of my boat and add a 5th speaker (via an amp). It would...
