Default Doubts between the Yamaha or the new Suzuki 350?

Maybe this video may help with the most important differences between the two...


...anyway it's a difficult choice.

Did I see the price right!!! 26 for Yamaha and 31 for Suzuki. The Yamaha seems to be a little slower turning higher displacment motor witch I like. But I am a Suzuki guy threw and threw I have two of them now and both of them have been flawless

For me, a very easy decision.

Zero sales/service, for Suzuki ( and, Honda, for that matter)...this is Merc and Yamaha country, and, "if you didn't buy it from us, maybe we could look at it around Christmas"...even under warranty.

Both Honda and Suzuki would be my first choices, but impractical where I own waterfront property, and I don't even own a trailer, or a truck to haul it with. There are two mobile mechanics locally, but neither are certified for warranty reimbursement work. Typical in a lot of remote areas, with low populations. In my case, a truck/trailer would be impractical anyhow, due to to a seawall...I still need a tow to closest marina, 1/4 mile away, the only reason I'm their customer, and having bought Yamaha from them, go to top of list for service.

Oddly, I have a Suzuki SX-4 car, now "orphaned" in US...150 HP, and I think the same block used in their outboard motors. Flawless. Due to retirement, I seldom get out of 2nd gear, and mileage around town is about 13mpg...when commuting to work, was close to 30mpg, in 6th gear. Great car, BTW, especially in heavy snow areas...locking differential , traction-control defeat, etc. Only time stuck: after snowplow pass, leaving me "high-centered" with all 4 wheels off the ground.

The video seems to imply that if you have a Yamaha you only need 1 or 2 engines but if a Suzuki you need at least 2, maybe 3 or 4. Am i misinterpreting it?

Yamaha 350 has a severe design defect. There's a harmonic vibration that occurs in cruising RPMs that causes the flywheel to break after about 100 hours at the problematic RPM. After denying any problems for a long time, Yamaha finally stepped up and now will replace the flywheels free for the life of the engine and calls this a regular service interval. It now provides a sensor which tells you when the flywheel needs to be replaced.

My son knows a delivery captain who runs boats to and from the Bahamas all the time. He carries a stack of flywheels because he has them breaking all the time on his runs.

For the normal owner with twin or triple 350s, think of the PIA factor of having to get the flywheels regularly replaced -- taking the boat to the dealer, leaving the boat, downtime til it gets fixed. I don't know how Yamaha can even go about selling the 350s. They haven't been able to solve the problem in the second generation engines, showing that it is an elemental design flaw.

Try the Suzukis or the Mercs.

Turbine wheels and spacers on some of the latest gas turbines (think Boeing 787 and Airbus A380 airliners, F22 and F35 fighters) have to be replaced at X hours or Y cycles. Are you saying that these engines have elemental design flaws? Have you thought about taking an engineering position at Pratt and Whitney or GE so as to be able to tell them how to design and built their products correctly?

Thats probably common maintenance on jet engines. Name one other Outboard in history that needs its flywheel replaced after 80 hours or it will blow up.

I worked at P&W in East Hartford for 5 summers while in college and grad school...was basically a gopher/helper on JT8D final assembly line. Everything was over-kill, as contracts were mostly cost-plus, and we were under constant FAA and DoD inspections. If your torque wrench was 3 days past calibration date, engine got red-tagged, just an example. Not a pleasant job, but paid 6x minimum wage...covered tuition. My father was in engineering there, the summer jobs all went to employee's kids enrolled in college.

Really now? His flywheels "break" all the time, and all he has to do is replace them on the fly and off he goes? I highly doubt it....replacing a flywheel might only take 20 minutes, but a flywheel/harmonic balancer failure on an F350 usually has much more catastrophic consequences.....

But I do see that this is another THT "I know a guy who knows a guy........"

What engines require turbine components to be replaced during normal maintenance intervals?

I don't know what the msrp is on the zukes, but I can tell you that's at least $10K more than you would actually pay for the motor, before rigging.

This is no where near the truth. I personally have 2 x F350s on a 36 yellowfin and have never had a problem with the flywheels. We cross to the bahamas 10 times a year and no issues. The new CPUs let you know when you have run 300 hours in the 3300 to 4300 RPM range. I have 2 other friends with trip 350s and the issues they have had have nothing to do with the dreaded "flywheel". They have blown the outside engines running hard in rough seas in tournaments which will happen with Mercs running them the same way. The outside engines dont get enough water as they are barking all day.

If the F350 had the power to weight of the F 119 ( F 22 fighter engine ) it would put out over 6000 HP.
3900 lbs / 35,000 lbs thrust - all ballpark bs internet #'s.

I'm in the same boat "literally ". 36YF twin F350's. It is a really nice combo of power and efficiency. I cross to the Bahamas about a dozen or more times a year and do not take flywheels with me. That's ridiculous.

The computer logs the hours in the RPM zone and tells you when you need to be replaced. It took me 335 hours to set off flywheel notice for the logged 80 hrs in the zone. I pick up the phone and call my Yamaha mechanic and he comes and replaces both on my lift in 30 min at no charge. The hard part is dialing the number to have it done. Such a non issue it's silly to hear non owners bitch about something that really isn't an issue.

Just hit 1200hrs and just normal maintenance. I've owned many outboards merc, suz, evinrude that never went 1200 without even a minor hiccup. Mine are the 2015 models. I fully comprehend the issues on the ealier edition F350's.
