Seven Marine vs Verado
Anyone done the comparison research between the 400r and the 557? I get that the 557 is nearly 400 lbs heavier which could greatly affect the cg of a high performance cat. I also get that they have not exactly been marketed towards the high perf cat sector but what I don't get is why? What is the opinion of the OSO brain trust as far as hanging a couple of these on the back of say a 28 or 29 cat? Anybody know the difference in price?
|
If I'm not mistaking the last blurb I read said the seine stuff started around 60-70a piece. They are pricy.
|
I understood they are around 185k a pair with rigging.
|
A 400r and a 627 have the same power to weight ratio. If the horsepower adds up to roughly thr same the verados are faster I think due to the verados higher RPM range.
Cost would push you to 400s everytime, you've got to want the seven and pay a big premium. I do prefer the look of twins and fewer outboards. Most boats sporting 4-5 verados don't look great imo. |
The Seven's would sink at 28 foot cat! 300's on a 28 Skater is max.
|
Surprised they didn't catch on in the performance world myself......But after the 450 and 500 Verardo come out they really dont stand a chance!

What are the true reliability numbers for the 557? IMO (strictly an opinion here & just an observation)The 557's are a novelty. I live in south Florida and 99% of everything is an outboard now. That being said, I have seen 557's once up here in Delray and twice in Miami. Every time I have seen them they were on a midnight express and I think the guy in Manalapan has them on a Mystic CC.
That being said most of the hardcore guys with Invincible, Yellowfin, Everglades & Intrepid, etc with nice 36-42 CC's around here rave about Yamahas for the multiple weekly trip to Bahamas with second place going to Verado 300 & 350's. Those guys swap outboards like underwear every 2-3 years. |

Don't these things run like a million hours and never need any maintenance and gold nuggets falls out of the exhaust? |

Because they have 800-1000 hours on them in a year and a half. We dont have winter, we run all year around and a lot of these guys fish 3-4 days a week. Its not a hobby down here guys, its a lifestyle. My neighbor has a 34 Yellowfin and goes to the Bahamas literally every Saturday at 5am and comes back Sunday at 5pm. |
I live on the west coast. I know how Florida works.

Heck, Dave, the Yellowfin guy does a new Yellowfin every 4-5 years. And they are not ragged but have a couple thousand hours on them. FWIW a good friend of mine has 800 on his Invincible with trip 300's and its 3 years old. Isnt that normal? |
Everyone says they like the reliability of a outboard.
The seven is still a car motor. |
I just have a hard time wrapping my brain around putting that much weight and torque on a transom and having it stay in one piece,,,,
|
I don't know that seven marine had a gearcase that would work in a surfacing application. I don't know how durable their midsection would be as well since it would take a pretty good beating.

mikebrls is at my marina. Dude, you might know them, two of the guys I am taking about are 1/4 mile away from Gateway. One is Coquina cove in the Yellowfin and one is at Two Georges (light grey Intrepid). Both Yammy guys & both change out in around 2 years.

Folks, you have to go back to why the "7" was developed. Their ultimate goal was to reduce the number of actual outboards required to perform. Those bigger motors are not going to like 'free spinning' and 'hooking' on the back of a cat or something that's going to leave the water often.
Hence, they have been designed and marketed toward the bigger fishing boats and center consoles. http://midnightboats.com/site/wp-con..._Customize.jpg http://www.powerandmotoryacht.com/si...oards-600w.jpg |
The value of center consoles has made ordering new every few years viable. The used engines retain pretty good value in the 500-1000hr range if they are 250-300 yamahas, any verado or a suzuki. The new power can be financed affordably too.
I saw an intrepid 475 with black hullsides with red boot stripes and 4 white 627s, holy **** it was amazing. One of my favorite powerboats I've ever seen. I haven't been able to find pics of it online. |
Didn't I read somewhere that the 7 motors had some weird reliability issues ? Something about vibration or resonance caused by mounting multiple engines ? Seems like it was only on the outside engines and not the center or maybe the other way 'round?
I wish I could remember where I heard or read about it. It's been a while and I'm sure they've got it sorted out by now. |

Bummer! Still had over 1000hp to get home on though!:evilb:

From a guy who has had them for a bit.
Thanks rocksandblues. I'm the guy and I’ve owned Seven’s engines for 4 years now and couldn’t be more impressed or happier with their product. I repowered my 2010 34Regulator in 2013/14 with a pair of 557’s and put more than +200 hours on them. Not one issue whatsoever. I then upgraded to the 627’s last year and have almost 100 hours on them. They are engineering beauties and I only had 1 minor issue; the port engine throttle-body injector malfunctioned. Seven over-nighted, that very same day, 2!! new throttle bodies; one to replace the malfunctioning unit on the port engine and one to replace the starboard unit that was running fine but they did so JUST as a precautionary measure, ALL under warranty. The repair was made within 11 hours of the diagnosis and I did not miss one minute on the water. Their customer service is exceptional. (It is important to note the throttle body unit that malfunctioned had nothing to do with Seven marine or their technology. It was a GM issue which could have easily affected any of the 200,000 Cadillac CTS V’s that share the same engine.) |
200 hours is nothing.

He talks about their customer service and a warranty fix that seemed to be above and beyond what Merc offers. |
Also 200hrs isn't exactly not using a boat. I owned the Sonic for 3 years and never put that many hrs on it.

Sometimes though, bad things happen to good stuff; no matter who puts it together: http://i29.photobucket.com/albums/c299/RRGOO7/3.jpg |
I know of that incident personally and that was not a Mercury failure.

But it illustrates the point of why the Seven Marine motors we developed. Comparable power/performance with less infrastructure. Sometimes 20% less. Sometimes 33% less. |

I look forward to the day when someone is bored with their Verado powered Cigarette CC, and clamps on some 627s.

Not sure if you all remember but Nortech ran a 390 w triple 557's some time ago. Boat ran 88mph or so. At the time everyone was stoked. Now price out 3 motors at 60k each. 180k.
Nortech builds a 390 with quad 400's. Similar hp. Motors around 30k each. 120k total. Seems like easy decision for me. By the way boat ran 100mph. I have seatrialed many Intrepid's with 7 power. They are also louder than the 400r also. However there seems to be the cool factor of owing a boat with them as not everybody has them. |

Also, did the Triple 557 boat have the T-Top on it for those speeds? The Quad 400 boat did not have T-Top when it they set that speed record. |
The quad 400r boat that broke 100 did have the top on. The first quad 400r boat did not have the top on when it ran 97 or so.
