1157.0. ""SPURS" Line, Net and Weed Cutter" by DANGER::BAUST () Tue Mar 01 1994 08:41

    Does anyone have any knowledge or experience with "SPURS" for an
    outboard motor (Yamaha 250hp).
    
    SPURS is/are a cutter which is attached to the prop shaft and to the
    prop itself designed to cut through fishing line, nets or weeds which
    become entangled in your prop or prop shaft.
    
    I saw it at the recent Boat Show.  It seems like a good idea, but I would
    like to get some opinions about its reliability, effectiveness and
    overal effect on the engine drive train.
    
    Comments, opinions, etc???

1157.1glad I have oneUNIFIX::BERENSAlan BerensTue Mar 01 1994 12:586
We have a Spurs on a small (25 hp) inboard diesel. It cut through a 3/4" 
nylon rope at half throttle with just a loud thump. It reduces our 
anxiety level considerably when sailing through the endless fields of 
lobster pot warps in Maine.

From the design, I'm not sure a Spurs would be adaptable to an outboard.
1157.2not needed...LEVERS::SWEETTue Mar 01 1994 13:005
    The need for them on an outboard is much less because if you should
    foul a line you can trim up the motor and take a knife to it
    easily.

1157.4NOT JUST YET PLEASEMR3MI1::BORZUMATOFri Mar 04 1994 16:3717
The spurs would be nice to have, on any type of boat.

With the outboard a knfie may cut the line, but i would definitely

be concerned about seal and shaft damage.  By the time you realize what

happemed the line is pretty taut on the shaft.

Nylon line will really raise hell, it also melts and is a real bit$h

to get off.

I have not seen any for an outboard, but i would call someone who 

sells them, can't believe they let this market go by.

1157.5Look at drivesaver for inboardSX4GTO::WANNOORThu May 05 1994 21:5810
    A month ago, we "ingested" a 3/4" nylon line into our propeller. It
    broke the transmissin coupling off, destroyed the transmission and I
    hope I hope did not damage my 1.5" prop shaft/cutlass bearing/engine
    etc.
    
    Spurs would have cut it free fine. Also, a "Drivesaver" flexible
    coupling would have helped by shredding before damaging the
    drivetrain...
    
    We live and learn; expensively.
1157.6Fouled PropsSALEM::GILMANTue Jul 26 1994 16:1225
    What 'actually' happens when you foul a line with an outboard is the
    following:
    
    Your running along watching for pot warps on a windy day with
    moderate seas.  THUMP, and the engine is stopped.  As you curse and
    race to the transom to tilt up the outboard and unwrap the fouled
    prop the boat is rapidly swinging stern to the seas and wind.  (After
    all the boat is now anchored by the prop). Now it becomes a race
    between boarding seas over the transom and how fast you can get the
    prop clear. If you have one of the modern outboards with the extra
    low cut transom which makes boarding people easier (also boarding
    seas) the race rapidly becomes 'interesting'.  If your not fast and/or
    lucky enough you could well wind up swamped.
    
    I consider lines fouling a prop a potential SERIOUS safety hazard.
    
    I have never been swamped in this manner, but one time I did get
    drenched thoroughly as I worked the line free from the prop. 
    Fortunately my transom is build for a long shaft so I had extra free
    board, and I needed every inch of it.
    
    The line cutting gear on the prop sounds like an important piece of
    safety equipment... expecially for an inboard.

    re .6
    
      When it is blowing like stink, sometimes you don't hear a thing until
    the engine slows/stops. About 3 seconds later debis that used to be
    the float for the lobster pots bubbles up. Before the boat completes
    swinging around, turn off the ignition, go to the aft end, and get a
    hold of the line and pull it over to a stearn side cleat. Do this quick
    before the boat loads the line. now the boat is at an angle to the
    waves and you can go about major surgery to the offending line with
    your handy super sharp knife. If need be, just cut the line. Of course
    this is for lobster traps. try such a move on someone's anchor line you
    just tripped is likely to get one into hotter water than said lobsters.
1157.8Caught LinesSALEM::GILMANThu Jul 28 1994 14:1614
    I doubt that the "Lobstermans' Association" endorses the pot line
    cutting method.......but, when its a WINDY day the seas are boarding
    there is little choice unless you can unwind it from the prop, fast.
    I  found that on one occasion that the line got so tightly wedged
    between the lower gear housing and the forward edge of the prop that
    I simply couldn't unwind it.  I cut it and retied the line, but that
    wasn't on a windy day.
    
    The idea about carrying the line to a stern cleat is a good one... you
    could take that a step further and take the line all the way to the 
    bow and then you could hang there indefinately while you worked the
    line loose.
