985.0. "Trolling Plate Input needed." by BOOTES::KEYES () Wed Feb 15 1989 14:45

    
    I need some questions answered on the use of a trolling plate 
    for large engines from those that use one or have used one.
    I recently purchased a trolling place and did not realize that you
    had to drill a couple of holes in the lower part of the motor 
    itself to mount it. I ws under the assumption is clamped on?
    However, before I deside to return it, maybe I can get some
    feedback from those who have or have used them.
            
    o Do they really work and how good do they?
    
    o Secondly, what effect would something like this have on the 
      engine performance. Thanks in advance for your assistance.

    What's "a large engine"?
    
    Out here, the "Happy Troller" is pretty much the OSF standard
    trolling plate.  You can get em at Costco for 60 bucks or
    you can get em from bass pro and those places for around 80
    bucks.
    
    On Lake Washington, there is no way you can catch sockeye
    without them unless you have a kicker that you can troll real slow with.
    
    The other method is to drag about 3 five gallon buckets behind the
    boat.  Also, I saw an add for a net recently that works on the same
    drag idea.

    Brett,
    
    The engine size is a Merc I/O 165hp and what I am assuming you are
    saying is that they do indeed work good. Also what impact would
    the happy troller have on the engine's performance when I want to
    open it up say to ski with without taking the plate off?
985.3Out of my leagueDECWET::HELSELI'm the NRAWed Feb 15 1989 19:3611
    Yup, I'd call that a big engine.
    
    Although I don't have one on my boat (small 80 horse merc),
    I think they are supposed to flip up and work okay when not
    in troll mode.  I share your anxiety about water skiing with it
    on, though.  It seems that you'd want to take it off for high speeds
    and un-mounting a bolted on unit is a hassle.
    
    Sorry, can't help too much.
    
    Brett.
985.4Slowing Down+++SALEM::JUNGWed Feb 15 1989 20:1938
    I think I can help you out on this one. I own a 14.5 ft. GRUMMAN
    w/ 25 h.p. Mercury motor. I bought the 25 instead of something
    smaller for the simple reason that I don't want to take all day
     to get across a lake. While the 25 does idle right down, after
    a while the engine starts to build up (carbon), and needs to be
    reved up a bit when she starts to idle rough. This rough idleing
    generally happens on rainy or humid weather. Anyway....I bought
    my trolling plate from Cabellas (sp) for about 75 dollars. The 
    mounting part wasn't bad at all. Get yourself 2 good c-clamps.
    Mount the trolling plate in position and clamp it to the anti-
    cavitation plate. I mounted mine on the bottom of the plate,
    it just fit better there than on top. Make sure that the plate
    is square (not crooked) to the motor. Since the anti-cavitation
    plate is aluminum the holes are real easy to drill. After the first
    hole is drilled, put in a bolt and nut, do this for each hole...
    PRESTO your trolling plate is installed (no problem, right?)
         I was impressed the first time out. Before I installed
    the plate, getting the boat on plane was a little wild. With
    just me in the boat the front end would come up quite high
    before plaining off. The plate, besides slowing me down to almost
    a dead crawl was now acting like a whales-tail. Now when I jump
    on the throttle Team Grumman jumps up on plane...fast. I can't
    think of anything bad at all to say about my Happy Troller.
    It's black like my motor and actually looks like it is part of it.
    In the spring time when the fish are hitting good at just about
    any speed the trolling plate isn't really necessary unless you
    feel like toy-ing around, but come late summer when your a little
    deeper- maybe using your Dave Davis's or maybe doing some down-
    rigging this unit will shine. Now you can pick ANY trolling speed
    you like -- right down to almost a dead stop. Any other questions
    feel free to contact me. Good Luck this year!

985.5You will never take it offSALEM::JUNGWed Feb 15 1989 20:397
    While the previous note is about a smaller motor than your 
    inquiring about I know of other bigger boat owners that agree
    it is an absolute MUST if your into serious trolling. As far as
    skiing and basic hauling ass goes your boat will jump up on 
    plane faster and in my case eliminate porposing just about
    totally. Like I said, can't say anything negative about my
    Happy Troller.
985.6SEA ANCHORSMTADMS::CURAVOOWed Feb 15 1989 21:2016
    I have a 22' cuddy with a 175 mercruiser and ran a trolling plate on
    it but changed to Sea Anchors. The trolling plate worked fine but
    I found I had more control and the boat was far more stable when
    fishing  in chop. Ease of use and maintainance was great. Throw
    them overboard, when done pull them back in. Thats it no holes in
    your motor, just tie them off on your cleats. I bought them through
    Sears for around twenty dollars a piece. I hang one over each side
    and the boat will troll down to almost a total stand still when at
    idle. To bring it up to about 2 to 2.5 mph I bring the RPM up
    accordingly and it doesn't seem to carbon up as readily as it did
    with the trolling plate. The best selling point though is how much
    it stablizes the boat in the chop. You don't seem to bounce around
    as much especially trolling parallel to the waves.

Re: .5 - What is meant by porpoising?

Also, would someone take 2 minutes and explain what a trolling plate is and
how it works?  I think I've gathered the fact that it assists you in trolling
slowly with a fast gas engine.

Not ignorant, just boatless,

985.8quick and dirtyRAINBO::MACINTYRETerminal AnglerThu Feb 16 1989 17:488
    porpoising (sp?) is when the boat's nose bounces up and down
    while on plane.
    
    a trolling plate is a piece if metal that drops down behind the
    propeller greatly reducing the propulsion and thereby reducing the
    boat speed allowing motors to go slower for trolling....

985.10BOOTES::KEYESFri Feb 17 1989 12:386
    Thanks for all of your input on the trolling plate. I will be 
    mounting it and drilling holes since it won't effect the performance,
    infact possibly make it better since it will help the boat to plan
    out faster. As for mounting it, I'm going to drill, use lock washers
    and wing nuts, so when I want to take it off it will make it that
    easier. Again, thanks everyone for your assistance.
985.11Question on Sea AnchorsDECWET::HELSELI'm the NRAFri Feb 17 1989 15:228
    I want to ask .6 about "Sea Anchors".  Are these the net like
    objects you drag behind the boat?
    
    If so, I've always wondered something that you may be able to help
    me with.  How far behind the boat do they drag and how come fish
    don't get tangled up in them?
    
    Brett.

    A "sea anchor" is a canvas bucket, dat come to a point on de bottom,
    sorta lak a fonnel. It has three lines holdin the front an one line
    frum de point ob de fonnel. Chew drag it behin de boat to slow it
    don an wen chew won to bring it in, chew pull it in wit de line
    connected to de point. Dey don take op space wen stored an kin be
    damn handy wen needed!

    Another cheap "Sea Anchor" is a good old five gallon "Spackling
    Bucket". I tie mine off the front cleats with about 6' of 1/4" line
    so they are along side the boat when in the water. (out of the way
    for fishing) If they bump the boat, so what? They are plastic and
    don't make a scratch. With a 120 I/O I get down to .5 mph at idle.
    Since they are along side, I simply reach down ad pull them in by
    grabbing the end of the bucket. (making it spill out as I pull up)
    The Coonas "Professional" models are really good but, mine serve
    as a bailer if I ever need them.

985.14THRUST REDUCER INFO. WANTEDKAOA01::COUTTSThu Feb 21 1991 19:1714
    Hi,
    
    I'm looking for information on outboard "thrust reducers" (for lack of 
    better description).  The ones I've seen bolt onto the lower unit and
    flip down to partially reduce the prop thrust.
    
    Does anyone have any experience with them?  How effective are they?  Is
    there a better alternative?
    
    My boat is a 15'6" Cadorette with a 70 Evinrude.
    
    Thanks in advance for any replies!

985.15less mph_higher RPM_less foulingSALEM::JUNGFri Feb 22 1991 11:0316
    It's called a trolling plate. Yes, they do work well. 
    
    There is a note in here discussing this item but I'm
    not sure where it is. They cost about $70-$80, easy
    to install and act similar to a "dole fin" or a 
    "whale tale" when in the up position. When flipped
    in the down position it's hard to get more than a 
    couple of mph. I'm not sure about bigger boats but
    on the Grumman I had the steering was greatly reduced...
    Only a problem on windy days. With the trolling plate
    in the down position I could troll so slow, a floating 
    Rapala would just be dragged across the surface. The
    motor was a 25 horse.

985.19Do Sea Anchors really work for Large HP Engines?BUFFER::KEYESFri Feb 22 1991 14:2617
    o I have a 20 foot Wellcraft with a 165Hp merc, that when I attempt 
      to bring it down to a speed to troll it carbons up. I know about
      trolling plates but I don't wanna drill any holes in my motor.
      So, the next best thing is to look at either a sea anchor, or
      5 gallon buckets. There is some talk in the notes file that 
      buckets work with a 120hp, but dosn't answer the question on
      the motor size I have. I like the idea od sea anckors since they
      store rea easy. I also like the idea of 5 gallon buckets since
      I can get them for free, and as mentioned in a previous note,
      more than likely they won'y hurt the boat. However!, will they 
      really work? Will it take you down to the speed required to 
      work lure's for fishing such fish as Laker's, Samon?, and the
      most important question, will my engine Cardon up??? To much
      of this can hurt it!!
    
      Thanks in advance for your input... Stan
    
985.20Better than a bucketSALEM::JUNGSat Feb 23 1991 10:2713
    With buckets, you are at the lowest rpm you can get, with the buckets
    holding you back to your desired speed. With a trolling plate, the 
    rpm's can be raised to help curb the fouling and still maintain
    your desired speed. My boat was a 14 ft alum that with a 25hp would do
    close to 30 mph. With the trolling plate down it wouldn't do anymore
    than 4-5 mph at any rpm. As far as mounting, you clamp the unit on with 
    2 c-clamps, drill a hole using the hole in the trolling plate for a
    drill guide, put a bolt in but do not tighten. Do this 4 times, remove
    the c-clamps, tighten the 4 bolts...you're done.
