Tuna trolling with 4 stroke

[isurus22]

Has anyone noticed a difference trolling with 4 strokes vs. whatever they had before. They are great for skittish fish because they are so quite but I haven't managed to troll up a tuna since I got it. If you catch tuna with your 4-stroke let me know because it least I will know it is just me.

Have fished a Galcier Bay with Hondas on the back last few times, almost hesitant to go back to the Able because of the number of fish this boat has raised - most on multiple hook-ups. Every engine puts a different frequency on the water though. Wouldn't come right out and say it's you, but definitely not 4 strokes.

I have only had My boat offshore a few times this year but have caught tuna three out of four times. Single 225 on a 23 foot boat.
Never a multiple hook-up on tuna but I'm still learning! [grin]

Was out on my pops boat a lot in June and July. Caught plenty of small bluefins. He has twin yammy 150 four strokes. Multiple hookups were mostly bluefish.

I run a single Honda 225 and have caught many tuna this year, back in early August I caught my limit of YFT with multiple hook-ups, I have caught tunas in Hatteras, VA, and Palm Beach. Here's another thing, I also will troll a 15hp Honda kicker on slick calm days and have caught Tunas on it aswell. I still think its more a matter of being where the hungry fish are and less on the sound freq. of the engines.

I'm running 4 strokes and have raised/caught/broken off a good number of tuna this year. I haven't tried the same fishing with 2 stroke so have nothing to compare with.

[OUTCAST1]

I have read accounts of people running sportfishermen who run their watermaker while trolling, claiming the hum the pumps emit raise more fish! Superstition? Who knows? I think it's pretty well accepted that fish DO respond to different vibrations and frequencies.

Just a couple of observations here: The "quiteness" of 4 stroke OB's is the reduced mechanical noise heard from the powerhead. The exhaust noise, below the water and through the hub is still there for the 4 strokes. In this regard, I think the 4 strokes may have a deeper (lower pitch) exhaust sound than 2 stoke OB's. Given the well accepted theory that the low pitch of large diesels attract fish, it would stand to reason that the lower pitch of the 4 strokes may be more "fish friendly" than 2 bangers.
In any event, I've seen many a 4 stroke outboard out fish my 2 strokes, many times--- but then again, a kayak could probably out fish me on many days.
It's a good excuse though.

I'm with GAW... Have noticed this, If we are fishing by ourselves(no other boats around) and you hit fish they will strike no matter what, But if you ever go out in the canyon and the big boys are around with there nice low hum of a diesel than i think it comes into play.. Just my 2 cents..

Amen - when in an outboard around 600rpm diesels, best to find our own fish away from them! (for more resons than one...)
