340.0. "Boat Maintenance Questions" by RGB::PAN () Tue Apr 18 1989 12:28


   Hello fellow boaters,

       Well, I finally bought a boat.  It's a metalic blue and white
   Glastron GT160 with a 85 Hp Mercury engine.  I fell in love with
   it as soon as I saw it.  It is the bigger brother of the boat that
   James Bond used to jump over the road in "Live and Let Die" (it was
   a GT150).
	Mike Smith and I took the boat out yesterday on lake
   Quinsigamond.  It as much fun as I imagined, though I doubt I'll
   be jumping over any roads in the near future.  I can't wait to
   go out again.
	I've decided I like boating enough to fix up some of the
   rough spots on the boat.   A few questions:  Is marine carpeting
   the same as indoor/outdoor  carpeting?  If not, can anyone tell me
   where I can buy "real" marine carpeting?  Has anyone ever installed
   Teleflex "Red International" series tachometer and/or speedometers?
   Are they any good?  How easy are they to install?

							Thanks,

 INDOOR/OUTDOOR CARPET IS THE SAME AS MARINE CARPET,MAKE SURE YOU USE
    A GOOD OUT DOOR GLUE TO HOLD IT DOWN.. NICE BOAT, I HAVE A FRIEND
    HERE ON LAKE CHAMPLAIN WITH THE EXACT SAME BOAT HIS IS ORANGE/
    WHITE WITH A 100 EVINRUIDE.
340.2Small Corrision bubbles on Lower UnitFSBMS::BSERVEYBill ServeyWed Apr 19 1989 12:4012
    I brought the boat home from storage last weekend, and now I'm getting
    set to do the usual spring tune up stuff... wax, clean the canvas, new
    plugs, check the lower unit EP fluid level, etc... 
    
    When I looked at my lower unit, there are a few little corrosion
    bubbles starting to show around the "keel" (aka fin?). It looks like
    these are being caused by the little bit of paint I've lost on the keel
    edges. (My doo-hicky plate is fine, thank you.) 
    
    Should I spend the effort to brillo these bubbles out? (There are so
    few and they are so small.) And if so, is there a spray paint that is
    reccomended for the touch-up afterward?

    RE.0
    
    Suggest yoy stay away from the water pressure type speedometers.
    They simply are not accurate. Get one with a small impeller that
    turns as the boat goes through the water. They usually have a digital
    LCD readout and are accurate to a tenth of a MPH. Any of the better
    marine supply catalogues will have them.
    
    Goooooo Fast!

re .3:

Ah, the old confusion between accuracy and precision. Digital 
speedometers/knotmeters do precisely display speed to the nearest 0.1
mph/knot. They are not that accurate, however. The waterflow past the
impeller depends on the shape of the hull and the location of the
impeller. The speedometer/knotmeter must be calibrated for each boat.
Without calibration they're probably accurate to plus/minus a few
mph/knots. Even with calibration the accuracy will probably not be 0.1 
mph/knot due to variations in waterflow with speed, tidal and wind 
currents, grass and slime on the impeller, etc.
