Hey Ralph - I don't know what's causing the problem with your motors and won't guess, but I know someone who can figure it out for you. If you're willing to spend the 'dime' call Craig on Oahu at 551-2139. He's a registered Honda technician and takes good care of lotsa guys' Honda outboards, including mine. On Oahu he'll come service your motor at your house. If worse comes to worst for you, maybe you can get him to go over to the Big Island. Good luck. here
just a suggestion you might try different fuel we have had some problems like yours in the shop reciently we drained the carbs and switched over to our tanks and the problems cleared up the fuel in the there tanks looked great but there was somthing wrong with it good luck here
The synergy between the 4-2-1 Performance Tuned Exhaust and the ECU programming on the new 75/90/115A four-strokes provides strong acceleration when needed in order to get the boat on plane quicker and allowing the operator to reach top end speed faster. These new outboards feature a unique SOHC/four-valve design where the spark plugs are strategically placed in the center of the each combustion chamber for the most efficient combustion with optimal heat conduction, which results in strong running and fuel efficiency. Equipped with standard features such as the Variable Idle System; a micro-computer controlled ignition system for quick starts and instant throttle response; electronic fuel injection; a low gear ratio (2.08:1) that provides increased low end torque; a fresh-water flushing system designed to make routine flushing easier and a high output 41-amp alternator, the trio are a perfect match for small-to-midsized boats. Other notable features on the Tohatsu 75-90-115A four-strokes include a new gear case with wider splash and anti-ventilation plates; adjustable steering friction and trim tab for reduced steering effort; an oil tray catch pan set underneath the filter for cleaner oil changes; an easily accessible and removable fuel filter; and a stainless steel water pump housing for increased durability. All three are offered with an optional multi-function tiller handle with grip end PTT (power tilt and trim) switch and are backed by a five year limited warranty.

With the introduction of their new MFS 75-90-115A four stroke models for the 2021 model year, Tohatsu now designs and manufactures all of its portable and mid-range four-strokes from 2.5-to-115 HP in-house at its Japan-based facility. Their four high-power outboards (150-200-225-250) are actually made by Honda Marine and adorned with the Tohatsu decals, logos and color schemes. [links]
Suzuki’s new DF115BG and DF140BG four strokes are going to shake up the mid-sized class of competitive outboards, offering new features not found before in this power bandwidth. Last season, Suzuki did a “reset” of its older DF115 and DF140 outboards, upgrading them to the DF115A and DF140A models, both of which share a larger 2.0 liter powerhead. According to my recent conversations with the Suzuki PR team, these new “BG” series four-strokes continue the evolutionary path to newer, better and bigger things, all while staying within the same lightweight footprint. These newbies are the first in their class to offer all the advantages of drive-by-wire technology. By bringing its proven drive-by-wire technology to its 115HP and 140HP in-line four-cylinder models, Suzuki is providing simplified rigging for a wide range of boat builders, along with silky smooth shifting, instant throttle response, enhanced performance and superior fuel efficiency. An upgraded compression ratio of 10.6:1 helps these new 2.0-liter displacement outboards achieve better top speed and acceleration by improving thermal efficiency. Fuel is delivered via a throttle body digital EFI system and fuel efficiency has been increased as compared to Suzuki’s existing DF115/DF140A models. Factory tests have demonstrated five to seven percent better fuel efficiency for these new engines at cruising speed. Other improvements include a 40-amp alternator on both models that delivers improved output and battery charging performance at low idle speeds, which is ideal for today’s power-hungry fishing boats that spend a lot of time trolling. The engines’ exterior features a sporty, streamlined exterior design and are available in both 20-inch (L) and 25-inch (X) shaft lengths. Both new outboards boast new graphics and are available in Suzuki’s Pearl Nebular Black and Cool White color schemes. The redesigned cowl also incorporates a new air intake structure with improved water separation and a silencer/resonator system to attenuate engine noise and provide a pleasant boating experience at all engine speeds/RPM. To make routine maintenance easier, Suzuki made it possible to replace the oil filter simply by removing the upper engine cover. A new Oil Spill Catcher surrounding the oil filter mount allows for changing the filter without making a mess. Suzuki also added an easy access Water Detection Fuel Filter to help protect the engine against contaminated fuel. For more information, visit www.suzukimarine.com.
On May 27, 2020, BRP announced that it had re-oriented its marine business by focusing on the growth of its boat brands with new technology and innovative marine products. According to a BRP press release, president Jose Boisjoli stated, “We will discontinue production of Evinrude E-TEC and E-TEC G2 outboard engines. Our Sturtevant, WI, facility will be repurposed for new projects to pursue our plan to provide consumers with an unparalleled experience on the water. We remain committed to our Buy, Build, Transform Marine strategy which has been underway since 2018 with the acquisition of Alumacraft and Manitou boat companies in the U.S., followed by the acquisition of Australian boat manufacturer Telwater in 2019.”
The 3.4L V6 and 4.6L V8 outboard engine models are available in five family configurations (FourStroke, Pro XS, Verado, Racing and SeaPro commercial). Most of these (the 450R is supercharged) are naturally aspirated and feature large displacement powerheads that have been designed to shed bulk and are incredibly lightweight. The XL versions of each engine weigh only 485 (V6) and 539 pounds (V8), so they should prove to be an excellent choice for boaters retrofitting older tired two-strokes with weight limitations on the transom. The V6 and V8 models offer class-leading displacement and a performance-inspired dual overhead cam design that delivers instant throttle response and immediate power. A single throttle body and long performance-tuned intake runners pack more air into the cylinders to boost torque. Yet another feature is Transient Spark Technology, which optimizes spark timing to produce more torque during hole shots. Advanced Range Optimization improves cruise-speed fuel efficiency by automatically adjusting fuel delivery so seamlessly, the operator won’t feel or hear it. Patented closed-loop fuel control uses a wide-range oxygen sensor to optimize the air-to-fuel ratio during all operating conditions. The unique Adaptive Speed Control allows these new Merc V6 and V8 outboards to maintain a desired rpm regardless of changes in load or conditions (such as rough water, tight turns, lower planning speeds, etc.). This translates to fewer adjustments to the throttle lever position – just set it and forget it. A convenient top cowl service door is another industry-exclusive and simplifies routine maintenance with easy oil checks and oil fills without removing the cowl. It also houses the latch release and a carrying handle just in case you need to take the cowl off the motor. Unlike some competitor’s high output four-strokes that require premium fuel to operate, the new Mercury V6 and V8 outboards deliver peak performance and reliability on less expensive 87-octane fuel.
Tohatsu’s new MFS75/90/115A four stroke outboards are a natural evolution of their best-selling MFS40/50/60 models and essentially feature a super-scaled design in a larger footprint. The legacy of their top performing and most reliable engines has been passed on to these next-generation yearlings, which include a host of industry-first innovative features and characteristics. One of the most interesting of these new enhancements is the ground-breaking 4-2-1 Performance Tuned Exhaust, which provides steady torque throughout the RPM range. The more torque you have on take-off, the faster/better the hole shot, in addition to having a realistic “passing gear” when you hit the throttle during lower cruising speeds. In engineering terms, the “isometric aggregated exhaust manifold” 4-2-1 maximizes torque and acceleration performance. This unique design is an industry-first and currently is a Tohatsu exclusive. By engineering each exhaust passage to be equal in length, the merging of exhaust of each cylinder creates extra suction that helps pull the exhaust from the engine. This completely eliminates the possibility of exhaust interference and drastically improves the performance.
That's a puff piece that magazines do to stroke their advertisers. He was just quoting back Yamaha advertising copy. I'll see if anyone here remembers what the issue(s) were and if they were solved. more
