All my boats have had Yamaha motors. The yellowfin 54 really caught my eyes. Quad 425s are definitely underpower for that size. Anyone knows anything about Yamaha's next move? Will they have a similar like the Mercury 600hp in the next year or so?

Thanks.

Strange you should ask, I'm doing the engineering work for Yamaha now for a 625 motor.

Why have 4 when you could have 5 or 6?

Thanks for sharing. 625hp Yamaha motors will be the true game changer for 50+ Center Console. Glad to know Yamaha is working on big motors.

My current boat is a 45T with quad 425 (12 ft beam), making it very tight on the back especially when fighting a fish or getting into very tight dock slip. A 50+ CC usually have 15ft beam such as the Yellowfin 54. If hanging 5 motors on the back even for the 15ft beam it will be very tight. 4 motors for a 15ft beam would be perfect. Besides 5 motors would look awful cosmetically. I would say 2~4 outboards look fine but not 5 or 6.

Not going to happen anytime soon. Yamaha lost this fight. I hope someone lights a fire under their ass. Competition is healthy.

One of the very reasons Merc did what it did. Imagine pulling up to the New York Yacht Club with this beauty! You aren't the only one that thinks eight outboards hanging off the ass end looks a bit silly and a bit kiddy...At 54' the idea of a pair of large electric motors w/outdrives and genny for the rest of it starts looking reasonable...



so, did you ever wonder where all those used 250 hp Salt Water Series Yamahas went...And no, this isn't photoshopped or the next Compmillenia Lightspeed. It is a very focused design with a single purpose only....

I assumed an old drug smuggling boat.

How exactly will a 625 Yamaha be a “game changer”? Seems like Merc has already beat them to the punch.

sorry, game is changed. Congratsyamaha.

I’d read his post again and ask yourself how likely it is he’s a Yamaha engineer releasing info on THT vs. sarcastically making the point that you’re not going to get a straight answer on THT.


I don’t understand how a Yamaha 600ish motor changes any games? Yamaha makes a fine engine, but it hasn’t been in a class by itself for a long time. If they play follow the leader with Merc on big hp, that’s great, but they’ll still be second (or third if you count Seven) to that party.

So, if you count 7, isn't Merc playing follow the leader...producing a 600 HP engine @ $80+K, that not even the top 1% of boaters will be able to afford? Are you suggesting that there is nothing that could better the Merc 600? I'll bet 7 thought that too at one time. Funny how 7 was routinely mocked for producing an outboard that very few people could use, at an astronomical price. Now, I guess it's ok...

Rmoody79

Well and considering 7 is out of business and no longer producing engines under Volvo...........

Just got off the phone with Yamaha in Japan. My Japanese is a bit rusty but they confirmed a 700 based on the 425 with forced induction..

jcozart

I'm a yamaha fan, but can you imagine the weight of a 625hp yamaha.........Somehow they would figure out a way to make it weigh 2k lbs!

Other than the F350s Yamaha makes solid engines. It doesn't matter which company to be the first. The quality matters. Most of the 50+ center console have 7's motors hanging off the back but we all know the quality, let alone the lack of service network and the 50 hours service interval. Hope the 600hp Mercury delivers but time will tell.

I hope Yamaha is working on 600hp+ motors for 50'+ even 60'+ center consoles. The Yellowfin 54 and the Gulfstream 52 are the beauty to my eyes.

KVKV

Once Yamaha comes out with the 600hp+ outboards, along with Mercury's 600hp, the big center consoles are getting into the traditional diesel world. There'll be a possibility that we see these outboards hanging off the back of a Viking.

Yamaha has produced some real stinkers over the years. HPDI 250/300 had terrible grenading growing pains and were quickly EOLed. F200/F225/F250 had exhaust corrosion issues. F150 had the balancer issue which could take out an engine. 4.2l engines have/had the making oil issues.
