    Hello all!

    I am happy to announce the successful maiden voyage of the "Floatsam" on
    Sunday, July 30 in the Charles River at the Watertown boat ramp (just
    west of Boston). We spent about 1 hour in the water and took on about 1
    cup of water. :)

    So much for the executive summary. Here's the dirt:

    As luck would have it, the Amphi had arrived on the one week that my
    friend Rainer was visiting me. Rainer is a Genuine German Mechanical
    Engineer and a fellow motorcycle/car lover (we have also discovered that
    he lives only 20 minutes from Hans Trippel himself!). On Saturday
    Rainer and I went off to get a grease gun to stick some nice new Amsoil
    into the little beastie's bearings. Part of the trip was via freeway
    (Rte 128 for you locals) and we learned two important things: 1) we
    gradually overheated at 65 MPH, but we were OK at 60 and below. Is this
    normal? 2) I lost some steering authority at high speeds. We expected
    this because of the hull shape.

    Upon our return, armed with oils, filters and grease gun, we finally
    bothered to check all the fluids and mechanicals (I know - we should
    have done that straight away, but you know how it is when you get a new
    toy). We learned that the oil was OK, but a touch low. Ditto for the
    coolant. We located 13 grease nipples - 3 under each front wheel, one
    under the hood (trunk? Anyway, the front), one under each rear wheel,
    one in front of each propeller and one inboard at the other end of each
    propeller shaft. ALL of the bearings were low or dry! We used up the
    whole cartridge, so I have 4 more in order. I still haven't done the
    propellers. We also discovered that one of the transmission mounts was
    completely smashed. As soon as I get a Gordon's catalog, I'll get a
    replacement. Question for the list: Should I replace the transmission
    mounts as a pair, or just the broken one? Also, the gearbox was about
    half-full of lubricant - certainly enough to keep the gears covered when
    operating. Is this the normal amount?

    The next day was cold and drizzly, but as Rainer is leaving in two days
    we decided not to wait. All the way to the ramp I was apprehensive
    while Rainer tried to think of everything we hadn't checked yet (a lack
    of documentation was rougher on my poor German than it was on me). :)
    Still, upon arrival we donned our spiffy new life jackets (just in
    case), offloaded the family and lined up with the ramp. Up to this
    point, our Amphi experience consisted of what we had read off of other
    people's web pages. Still, it was supposed to be easy, right? We were
    cheered on by about 18 onlookers, mostly a rugby game that stopped to
    watch the spectacle. Success! It went right in with barely a splash.
    No leaks detected and the bilge pumps (the prior owner installed 2
    backups) had nothing to eject. After 15 minutes we docked with a
    floating dock to test the navigational properties. By now the
    wife/mermaid had decided that we weren't sinking, so the handed my son
    Kevin (age 2) to us to take out. The biggest problem all day was
    explaining to Kevin when it was time to share the life vest. :) I then
    took our friends Chris, Helen and Erin (also age 2), who were kind
    enough to video the expedition) out for a little swim. Their pics and
    video to follow. We ran the bilge pump a couple of times and managed to
    get it to spit water once. Upon finishing the cruise, we opened the
    bilge plug. Less than a cup came out. :)

    Next steps are to replace the broken mounts and hook up the heater again
    (it's been totally disconnected). Also, the generator can't keep up
    with the load when the headlights are on. Is this normal?

    More as things develop, and a huge thanks to everyone who's contacted me
    with advice.

    -Drew

    Drew:

    Congratz on your maiden voyage! I'm still shaking off the voyage back from
    the Celina spawning grounds, but have injected my comments below.

    Depending on ambient temperature, rate of speed and incline...Sure, it'll
    warm up a bit. On an 80 degree day going interstate my temperature gauge
    will edge right up to but

    2) I lost some steering authority at high speeds. We expected
