Default Questions for those that OWN a boat with twin OB's

Please don't turn this into a "Twins v. Single" thread. There are many already, and I have read them.

For those guys with monohulls and twins, and who troll (the fishing kind not the internet kind), do you troll with one motor running, or both? If running one, do you have maneuverability/steering issues at trolling speeds? (I suppose the answer might be different if you are running a cat, so I direct the question to the mono guys). Trolling speed for me would be ~3 mph for stripers, and ~5 mph for spanish mack.

I assume that if you are running twins, you probably had a single before that (yes, I am aware of the dangers of a-s-s-uming anything). Aside from synching the motors at speed and of course the docking differences, what day-to-day operational differences do you see, if any, with twins? (I know all about the double maintenance costs, etc; that is not the basis for my question; also not interested in "advantages".....just "differences" that would/could effect the day to day operation of the boat). For those running new-ish Yamaha digital twins, do they have a synching feature? Any other electronic aids for twins?

This question is directed to those who actually own and run twins...not those who think they know what they would do if they had twins. Also not interested in opinions on the single v. twin debate.

Thanks in advance, and of course Happy New Year to all.

My boat came with that old giant two stroke Johnson 300 they used to make. ( 25 foot Hydra Sport) I ran the boat for a few years with that motor. I repowered with twin Suzuki DF 140's. I also added a floatation bracket for the twins. This is a heavy boat for its size and with the single I had to be on the throttles quite a bit in a sea to stay at a comfortable, steady speed. With twins it is pretty much set it and forget it on the throttles. I think this is because of the two props in the water advantage at slow to medium speeds. (my top speed remained pretty close, with the single being a few mph faster) Fuel use was cut almost in half. Overall, the boat handled much better after the repower, but some of that is probably attributable to the bracket.

Regarding trolling, I have tried both methods (troll on one or troll on two) a lot and can't see much difference in handling, number of bites, or fuel use. I usually troll on both since I am one of those who rarely turns a motor off when offshore.

I have a mono hull with twin 300's. I will troll with both or single depending upon how I'm feeling, the current, the wind, and if I remember to turn one off. A good bit of the time I will only use a single motor so that I don't run up the hours on both motors. I do have an auto-pilot and I will usually plot out a path where I want to go before I get out there. If I find the fishing is not what I'm expecting, I'll go manual. There is no right or wrong answer to whether you troll with single or multiple motors - it's really about the conditions, your comfort and skill level, and the kind of fishing you're doing.

Century 2600w/twin F225's- always troll on one, occasionally switching motors. Both motors trimmed down, no maneuverability issues.

I troll at 3 mph with one engine for 8 hours at a time, no probs. I don’t know about the syncing but i just match my rpm’s from the throttle manually and have no issues. Twins are awesome. Always better than a single!

I have twin F200s and troll for stripers with one motor all the time. No problem what so ever. I normally switch motors when I make a move (run port vs starboard) to keep the number of hours equal between the two motors.

Twin 300’s here. For rockfish we troll with one engine usually to keep around 3mph. Autopilot keeps us straight. I do tend to switch which motor is in gear at random times. Both motors are always on

All of the above are very helpful; these are just the answers I was looking for. Thanks.

Cheers.

I always troll with both motors on and in gear, to keep the engine hours close. If you go to sell your boat and one motor has different hours than the other it opens the door for all kinds of questions as to why the motors have different hours and can
turn buyers off

This is just wasting gas??? Run one for 4 hours and the other for 4 hours. Problem solved and more money in your pocket for next trip

I thought most people wanted to troll around 6kts. What are you going for where only one engine is needed?

I troll on motor to keep the hours down on the motors as long as we are trolling up to 8 knots or so but if we are high-speed trolling I don't have that option. Over about 8 knots the engine sounds like it is laboring and I will go to 2.

Troll on one engine for slow, slow (stripers). Troll with two if faster or depending on conditions. Had a slip in a protected area in Boston and had to use one engine all the time because running two moved the boat too fast in that dead calm. Nice to have twins and have more options (docking, etc). Less draft, better sea handling, etc. Added cost not a factor to me, so it’s all upside.

Both motors, most of our trolling is 8-15mph depending on what we are going after. Both work better for many reasons compared to running just one. Also use tabs to level boat out and make a better wake, will bury them at times, do not care about the cost when it might take 100+ mile run one way to get to to trolling grounds. In the greater scheme of life, spend 100s of $1000s on boat, gear, gas, etc... to get where I want to troll/fish. Not going to cheap out because of hours on engine or a few gallons of gas.

I troll with both motors running.....the etecs use hardly any gas at all trolling, so it's a non issue for us.
On a heavy boat like a Grady with alot of wind exposure, it handles much better with both props turning....I prefer the sound of twins sync'd up and I like to keep the hours close...both are within .5 hours of each other...the biggest deal is if you get a decent hook up, you can turn on a dime if necessary.....

I troll with only one motor running. There is nothing to be gained from running both motors except more fuel consumption and noise.

I will switch motors throughout the morning to keep the engine hours balanced.

There is no loss of steering control at these speeds.

I troll with both running, except when I’m bump trolling live bait.

Run twin 300 Verados. Never shut the engines down when I am offshore.
