    How much chain is too much?

    One consideration is the load rating of the windlass. It should be rated three times the weight of the entire rode; line, chain, and anchor. I have 200' of chain in my 30'. At your depths you could use much less. Make sure to have at least some line so you can cut it off if needed. I...

    Volvo Penta 305 - Squeak and Rattle

    FYI. Belt dressing is intended for V-belts, plus it makes a mess when it flings the dressing off the belt.

    Troubleshooting Ignition Wiring Short

    It turned out to be one of the purple ignition wires shorting to the block at the alternator. It's been rubbing for years, but I just tightened the belt and that added a bit more pressure to the chafed wire against the block. Luckily it was a hard short so that made it easier to chase down...

    Right Hand Prop versus Left Hand Prop - OEM versus installed

    I wouldn't worry about that design difference. Both ends are supported for axial loads, just in different manners. Twin engine installations run a drive in each direction with no issues.

    Troubleshooting Ignition Wiring Short

    I have a short in my ignition circuit on my '95 joint venture (Volvo/OMC) Ford 5.0 EFI engine that I'm about to start troubleshooting. The 20A circuit breaker for the ignition system is blown. While cruising at 3000 rpm the motor just shut off, no sputter or any hesitation prior. Right at...

    Right Hand Prop versus Left Hand Prop - OEM versus installed

    The way to tell is to put the shifter in forward and try to spin the prop in the forward rotation direction. If it spins forward, but not backward, it's set up for forward. Yes, if you put a left hand prop on and switch the linkage, you'll be using the other side of the cone for forward...

    1996 Four Winns Sundowner with 5.0 Cobra engine and drive

    @Lpgc, This is unrelated to the topic above and I can't remember if this has been mentioned in this thread. One thing to watch out for on these engines is corrosion of the fuel reservoir water ports. The fuel reservoir is on the back of the engine, right under the power steering cooler. There...

    Volvo Penta overheating

    First I would backflush the cooling system and find all the missing impeller blades. They are likely clogging key parts of your cooling system. If you're raw water cooled, this would include pulling the thermostat in the flushing process.

    Zinc contact points- sand clean?

    I've read that wire brushing is not good for a sacrificial anode as it imparts some steel onto the surface reducing its effectiveness. Rough sandpaper is what I use.

    Zinc contact points- sand clean?

    I sand the small raised contact area around bolt holes to improve conductivity to the drive/transom. Yes the bolts provide most of the connection.

    Older radios typically receive GPS data via a NMEA 0183 cable (or NMEA 2000 for newer radios) with data coming from a GPS antennae. The function is to enable the distress button to transmit your coordinates.
