    1995 Joint Venture Drive Compatible with Volvo Dual Prop Lower End?

    Curiosity question... I have a 1995 OMC SX joint venture outdrive (50FAPHUE) and was wondering if it's possible to install a Volvo dual prop DP lower end. Are the Volvo drives metric threads? I know I need 7/16" nuts to RnR the OMC outdrive, so I assume the entire OMC unit has SAE threads and...

    Helicoil in Transom OK?

    While replacing the anode on the transom of my OMC Cobra outdrive on my signature boat (same as Volvo Penta SX), I managed to strip the threads in the transom for the anode due to corroded threads. I plan to install regular helicoils for both bolt holes using loctite to hold in the helicoils in...

    Outdrive Water Drain Plugged

    I doing my first winterization on my signature boat (50FAPHUE) and once I finally removed the water drain plug on the port side of the outdrive, I found it fully corroded and blocked on the inside. I tried cleaning it out with an awl, but couldn't expose the internal water passage. It appears...

The provided OMC pamphlet manual talks about removing drain plugs on the block and exhaust manifold on both sides of...

    Boat Stop to Bowl Loop Distance

    We recently purchased our first boat, a 1995 Chris Craft Concept 21 with original trailer. I wanted experts' opinions on whether I should move my winch tower to get my bow stop closer to the blow loop. As the attached pictures show, I'm limited in how far I can pull the boat forward by the aft...

    Difficulty Shifting to Neutral with 1995 OMC Cobra SX

    Just purchased my first boat; 1995 Chris Craft Concept 21 with an OMC 5.0 EFI motor with Cobra SX stern drive. Overall in excellent shape. One area I'd like to improve is shifting from FWD to Neutral. When the engine is running the transition is a little stiff. Engine off the transition is...

    Trim Sendor Wiring Removal

    First post... I'm trying to remove the trim sender wiring from the transom on my '95 OMC Cobra SX. It looks like gasket sealant or something was used and I'm afraid if I pull on the wiring too hard I'll be left with just the rubber grommet in the transom passage. Yes, I removed the clip. Is...
