Default A Friends 25` Shamrock /Trolls 2 Fast!

A friend of mine re-powered this past summer with a new 5.7 EFI engine...Great
job done by the installer, but,!!!! This boat trolls way toooooo fast to be effective
on strippers(no Tide 4 to 4.5 knts) and wirelinning for flounder is totally out of the
question. Does anyone have any ideas on how to slow this rig down to 3 knts or even slower..He hasn`t got it yet that his boat trolls too fast and unless the bite
is a frenzy he only scores 1 or 2 fish tops, when the majority of the fleet limits out.
Shifting trany in/out of gear is not an option! Too much wear and tear. So ok people what ideas have u got? Boat is 25` Samhrock w/9` beam cuddy cabin.
All help will be appreciated.

I have heard that some owners will attach a set of buckets or sea anchors to bow cleats to slow the boat. You clearly must use a short piece of rope so not to entangle the setup in the prop. You may want to visit Fish The Classic.com for more info.

Trolling bags. In the great lakes we seem to troll much slower ( 1.0 to 3.5 mph) than you guys in the oceans . We use trolling bags to slow us down. These are much heavier duty than sea anchors, I use Beefy bags from Amish outfitters. Once you get the line lengths set properly they are real easy to use. I run them from the midship cleat to the stern cleat. They also help to stabilize the boat in waves. run one off each side or you will go in circles.

First check that the idling RPM isn't too high, then perhaps take a look at whether prop pitch is correct. Something seems to be out of whack for just idling in gear.

Agree 100%. Sounds like something isn't quite right. re-powered my boat last year and came back with the same issue. Turned out to be simple timing and idle adjustments.

I thought strippers liked it fast?

He was told that the engine is an EFI( electronic Fuel Injection) the idle setting
is set by the ing.system and the Fuel Injection metering, therefore system is non-adjustable. Should have added this to my orig. post.

Mine does the same thing and here is an easy, cheap and very effective solution for getting down to 2.5 knots.

Take two buckets and drill two holes in the side near the top, one on each side.
Get a 60 foot piece of rope and slide through the holes in the bucket.
Tie one end of the rope to the stern cleat port side, the other end to the stern cleat starboard side

Boom. Done. You know are trolling with a bridle of buckets across the stern and will be down to desired speed. Still too fast? Add another bucket.

Works perfectly and is super cheap.

True to a certain point and then not true. If the idle rpm is high then something is not working right even on an "electronic" engine. I would suggest you find out what the idle rpm should be and verify if it is correct or not. I agree that if everything is fine then throw a bucket out but I would like to know my engine; that I just spent a lot of money on, is set up the way it should be.

go to fishtheclassic.net not .com. It is a Shamrock owners site and this is a common topic. Buckets is the quick cheap effective fix. You can spend $$ for small sea anchors, which do the same thing, or you can spend big $$ and get a trolling valve installed. Good luck

used buckets for years on Lake E--I use a hole saw and make 4" in center keep this big washer and made another--- now put a tow harness( a piece of rope) from the inside out through the 4" cut outs (instead of the bails) -- buckets can be attached with another rope with a quick connect--- may the harness long enoungh so the buckets will store inside on each-- I put on center cleat and then are out of the way

This is a common complaint on Shamrocks. Even with the idle at 500rpm mine is still a little too fast for stripers (but I got a couple of Spanish Macs). The simplest answer is to drag a 5 gallon bucket. BTW, It is pretty laughable to a shamrock owner for outboard guys to say a bucket might get in the way of fishing. Remember, we don't have an engine or outdrive back there. Trust me, there is still plenty of room to get big fish on board with a drywall bucket a couple of feet behind the boat. The cool thing about a Shamrock is with a keel and bronze shoe over the prop, even the nastiest fish can't find anything to tangle the line on.

I have the same problem with my boat and I believe you are at the right idle speed. I have basically the same engine, a 350 (5.7 liter) Indmar EFI and my idle is somewhere between 600-800 RPMs (not exactly sure, I've had the boat for less than a year and haven't been on her since October) and speed is about 4mph to 4.5mph according to the GPS. Putting the trim tabs all way down will help help out some but probably not enough for Striper, usually gets me down to 3.8mph or so.

I'm planning on purchasing one or two of the Amish Outfitters trolling bags, that someone mentioned above, for next fall's Striper season. The best way I've heard to set them up is to tie a line to the bow cleat and then to the front of the bag and pull the bag amidships, then attach another small line to back of the bag and secure it to the amidships cleat. This line is used to quickly pull the bag out of the water without having to stop the boat. I'm hoping this will work without being too cumbersome.

While the buckets might be a cost effective way of solving this problem, I'd just prefer not to put anything off the stern. One of the main advadtages of having a Shamrock is the clean unobstructed transom. I'd like to keep it that way.

Also, check out this online article for what is probably a better explanation of what I just gave: http://www.floridasportsman.com/boating/050958/

Other than the trolling prob; how does your friend like the Shamrock? I love mine!

My pal loves his Shammy, and I have fished with him alot and If I was in the market for a boat I would be looking that way, I repowered my rig in late 04
with a new 4.3 MPI/EFI (v-6) I don`t have the trolling speed problem, I guess
because iy`s a 6. But, I do like my results with the new power plant..I to was
concened with the possible trolling speed before I had it done,but I don`t have
that problem, as a matter of fact, knock on wood, I haven`t had a minutes problem since the job was completed. I will say that Shamrock is one fine and
seaworthy craft, would recommend them to anyone.

Drift bag - trolling bag will come with a good harness, are weighted properly. I think I paid $70.00 for the large.

The drift sokcs are ok it you don't fish that much, but there are lesss cumbersome solutions for the everyday angler that fishes more.

You can tilt the motor up to slow yourself, but this is usually not too effective.

You can buy a metal flap that is hinged behind the cavitation plate. It has an actuator that will push it down to your hearts desire, directing the water from ther prop down at an angle, instead of straight back, partially blocking it, etc.
