This previous summer time, my cousin spent 13 hours at anchor within the water off Panama Metropolis, Florida, in a center-console with no T-top. When a part-time information’s single outboard gave out throughout a half-day crimson snapper journey, my cousin and two different anglers aboard ran out of beer ready on a tow service. Fortunately they’d loads of sunscreen.
Therein lies the enduring argument for twin outboards, particularly for the risk-averse. Even with elevated dependability and the multitude of single-engine boats often returning safely from offshore journeys, there stays a slim probability of being stranded with no backup. That threat will increase for boaters who’re lower than diligent with upkeep, which I think could have been true on this the case.
Past the security advantages of a redundant system, there are different concerns which may outweigh the slight threat of getting to get a tow when making the choice between one versus two outboards. The flexibility and offshore capabilities of monohulls within the 23- to 26-foot vary has made them a number of the hottest saltwater fishing vessels in the marketplace, which implies there are plenty of boating anglers who should make a alternative.
“It is a boat class for which many patrons want to take a look at the pluses and minuses of a single outboard versus twin outboards,” says Dave Greenwood of Suzuki Marine. “Neither alternative is a foul one, however there are concerns that may affect your resolution by some means.”
Listed below are some elements to consider when attempting to determine easy methods to energy or repower your boat.
Value Comparability
Two outboards are going to value extra, probably twice as a lot as a single. This contains the acquisition value in addition to the price of rigging and labor throughout set up. On high of that, you’ll need to pay for the often scheduled upkeep of two outboards as an alternative of 1.
Gap Shot
Typically, twin outboards rise up and out faster. Acceleration varies extensively resulting from a bunch of things, however two are often higher than one on the subject of a fast gap shot. With equal horsepower, twins have extra blade space to punch out of the opening, which drives higher acceleration. Sure, weight and drag are each elevated with twins, however the added punch typically outweighs these elements throughout acceleration.
Boatspeed
Theoretically a single outboard ought to be quicker than twins, all issues being equal. However that isn’t all the time the case. Efficiency bulletins often give the top-speed nod to a single outboard when horsepower and hull weight are equal. That is defined by the elevated weight of two outboards in comparison with one, in addition to the elevated drag on two decrease items.
Nonetheless, this isn’t all the time the case. There are cases when—all issues being equal—twins put up increased high speeds than single outboards. This could possibly be resulting from setup elements equivalent to propping and engine top.
Additionally, boaters usually enhance their horsepower after they determine on a twin setup. There’s added expense, however there isn’t a lot added weight when contemplating twin 150s versus twin 200s. Compared with a single 300, you get a 100 hp enhance, which makes for a giant top-speed benefit.
Gas Effectivity
The only outboard comes out on high when you’re wanting to save cash on the pump. A single is lighter weight and produces much less drag than twins, all issues equal. This leads to higher gas effectivity.
Once more, this generality is topic to quite a few variables, however side-by-side assessments give a slight benefit to the one at cruising speeds, with the gas effectivity of the one performing even higher compared at decrease speeds. Take into account whether or not you’ll principally be working from spot to identify or when you’ll be doing plenty of trolling at 6 knots or slower if gas consumption is a vital consideration to you.

There’s a clear-cut benefit to twin outboards when maneuvering in tight areas. When you’re a boater who docks at a busy marina or must jockey the boat round at a crowded launch ramp so much, the power to make use of opposing thrust to assist steer is a profit price contemplating.
With follow, it’s not too troublesome to make a twin-engine boat spin on an axis, flip sharply with out swinging the strict, and crab-walk sideways as much as the dock. In terms of negotiating tight quarters with present and visitors, elevated maneuverability is peace of thoughts.
Some twin-engine outboards and steering techniques additionally permit for joystick management, which makes piloting the boat at gradual speeds thought-free and straightforward. These similar joystick techniques may present superior digital anchoring when related to GPS positioning, just like the anchor perform of a GPS-enabled trolling motor. That stated, some single outboards supply a joystick choice, however there may be much less performance with a single versus twins.
At velocity, the added weight of dual engines on the transom may negatively have an effect on the stability and trip of the boat, however that is extra of a difficulty when repowering a ship initially outfitted with two-strokes and never designed for the considerably heavier fashionable four-strokes. Nonetheless, many four-strokes now weigh about the identical as older two-stroke variations.
Ease of Use
There was a time when working two or extra outboards added to the trouble of sailing. At this time, because of technological developments, a twin-engine setup is as straightforward to function as a single outboard.
Even synchronization of revolutions per minute and trim angles is simple because of advances in digital engine controls. All twin engines include twin throttle/shift levers, however new techniques permit management of revolutions per minute and trim for each motors with only one lever and trim change whereas underway. Some power-steering techniques allow you to show a number of outboards with a finger.
There isn’t any one-size-fits-all within the twin-versus-single-engine debate. When you’re out there for a brand new saltwater fishing boat within the mid-20-foot vary or if it’s time for a repower, contemplate the varieties of fishing and boating you do, and make your resolution accordingly.
