    Johnson 200 Ocean Pro

    Hi. I'm looking at a boat for my oyster farm. It's powered by Johnson Ocean Pro 200. I'm not yet sure what the year is, but it's gray in colour, if that helps. I'd like to get an idea of the fuel consumption at WOT (and oil consumption, as well) so that I can figure out what it's going to cost...

    Dyed fuel getting into oil?

    I have a 2003 BF200. When I check the oil, the volume seems to have increased. Our local outboard tech tells me that it's because I'm using dyed marine gas and that the dye is getting into the oil. I also note that the oil itself seems to be developing a reddish tinge, so maybe it's true...

    BF200 Propeller Size

    Gentlemen: I have a 2002 BF200 (bought new in 2014, but that's another story) powering my 23' workboat. It currently wears a 14x19 4-blade aluminum wheel. With a clean bottom and the boat running light, WOT only produces 4500RPM. I would prefer to stick with the 4-blade wheel, and don't want...

    Walter RV-40 V-Drive

    I have a pair of Walter RV-40 V-drives that need new (rebuilt??) CV joints. Walter says that they not available any more, but that they'll happily sell me a new set of V-drives for $8,000. The gears, bearings and everything else in these units are showing almost no wear, and I just can't justify...

    B-W 73C 'Whirring' Noise
