We do all of our own servicing except for the 300 hr service.
As long as it's a non issue for you guys. I know it's an issue for some folks.

I look at it as a free checkup every 300 hours. I haven't had it done yet but figure I will have the shop go thru my motors on Yamaha's dime.

Absolutely correct. It took me some time, but I confirmed it with Yamaha. Aside from that, the reports from F350 owners are largely glowing (like any motor, some have had issues). I actually decided against an F350 though because I do most of my own service work, and dragging the boat to a distant dealer for a new flywheel every couple of years would be an extra obligation I didn't want (we do our boating 50 miles from everywhere, and the boat is on a lift).

I would definitely say the Verado 350's because with Yamaha, they will lose about 25 horses after about the 400 hour range. Mercury has nearly perfected the performance of their engines they will almost never lose power unless you try and go on plane with one engine.

You know, I've got the same question. Thinking about a 39YF with trip 350s, but would you go with yam or merc? I've loved my previous yams, but also really like the mercs on some other boats i've fished. The one concern i have with mercury would be over in the islands where the fuel is poorly graded. I've heard of countless merc failures over there because of fuel issues. But on the other hand, those thieves in the bahamas tend to target boats with gray motors. More time and tests will aid my decision.

No more failure prone fuel flotas on the latest generation of Verados, this was the main issue with fuel related problems. I would not personally own a V8 Yamaha, as torquey as they are, we see too many major issues. Service wise, Verados are much easier to take care of as well, don't need to spend an hour removing plastic to access things.

Where did you hear this? At the 200 hour range I guess they gain 25 hp because we can now hit 68 with 250 gallons of fuel and 6 men and 400 pounds of ice. Used to only hit 67-68 light.

They lose more than 25hp when they explode

They actually gain 350 hp if they explode in the next 5 years! 😎

A lot of good thoughts and opinions,,,, thanks for bearing with me as I posted the wrong thread title....think one thing and another dribbles out my fingers.
I await Tailin Stranges numbers and prop data.... My buddy has twin F350's on his boat and has had zero issues, with them.... So I am really looking for the fuel data/cruise/rpm best case scenario. 65 MPH vs 70 mph holds no appeal to me.... Cruisin, talkin,drinking suds and traveling in comfort. after a hard day fishing is what I really want out of my motor choice.

I just can't help thinking that if I was 100 miles offshore and my flywheel flew off, I wouldn't be so ho hum.

I would assume that if Yamaha recommends and funds flywheel replacement every 300 hours, the flywheels probably have a minimum life of 450 hours but more like 600-900 hours. But maybe Yamaha doesn't give a damn anymore about their reputation and they will fail prematurely. The F350s have now been around for 7-8 years so one would think they've worked out the kinks. The v350 is brand new so that would scare me more 100 miles offshore.
To present my case though.....if Tailin Strange's boat crushes my boat, I would strongly look at the Merc if I was buying another 34vh. Which ever motor performs better and has at least a 5 year warranty would be the smart choice.

Verados have been out since 2004. The Mercury Racing 350 Verado came out in 2008. They have been refined and improved many times over the years. Mercury even went out of their way to fix common problems like fuel floats, lower units, ignition coils. This scares you? I would be much more worried about having an engine backed by a company that can't find a simple fix for a flywheel that has the potential to wipe out your powerhead. What about when you lose a lower unit? Does Yamaha have a fix for that or do they install the same sized lower unit that you just destroyed?

BTW, the 350 Verado comes with 3 years of standard warranty, 3 years of corrosion warranty, and 4 years of available extended warranty for a total of 7 years of available warranty.

No, they have you rebuild the stupid thing, you don't even get a new one! Their technical assistance line said it's cheaper for them to replace every single part inside that gear housing than to send us a complete unit, so that's where the logic is with these guys. Mercury on the other hand, you have a bad seal and get water in the case, new one is on the way! So go figure?

I stand corrected. I thought the new v350 and 400r were completely different than the even updated Racing 350. I thought they used new super chargers and different gear cases and all kinds of new improved great stuff. If you're claiming it's even close to the same motor of 2008 thus having 7 years of testing, I would stay clear of it.

I know you are simply trying to show Mercury has been around forever and stand behind their product and are evolving (where Yamaha seems to be stagnant). I'm not arguing this. If this isn't a new line then why the hype at the Miami boat show? New products usually have some kinks in them whoever produces them that's all I was trying to say. I personally would like to see them running on someone else's boat a year or two before I bought them.

It's the same basic platform, just has a new water cooled supercharger and intake baffle system to keep the salt out of the engine and the intake temperatures lower to make more power with less stress. Few other minor tweaks such as cam profiles, programming, and fuel supply, but essentially the same reliable platform we've had for 11 years with all of the improvements that have been discovered over that time period. I definitely see Mercury as much more of a proactive company when it comes to product updates, refinement, service bulletins, etc. where as Yamaha is more reactive.

The Vrods actually produce 350 hp. The F350 closer to 320. But, that is at WOT so is only marginally relevant to actual operation.

I've heard this from other members so I went to the epa website where it seems this information is obtained. The F350 has 350 hp according to the epa. Where did your information come from?

funny to see people claim a V8 5.3L block making less then 350hp. That is a massive outboard that has no problem making it's stated HP, and can make a lot more.
