Yamaha 90 hp - what year?

[Fregata]

Hi, I have the opportunity to buy a Yamaha 90 hp for our boat, a Shakespeare Clubman 14ft....got a Mercury 60 hp from 1995 on it today.

Can anybody help me to find the right man.year for this Yamaha?
( s.nr. 6H1L 351205 90 AEZ )

P.S. Would the Mercury`s "Tower of power" 115 hp from 1984 be an overkill for this boat?

Re: Yamaha 90 hp - what year?

Here in Norway the Yamaha 90hp got a very good reputation for beeing a fast motor. It may got less torque because of the small cubic inches compared to f.ex the Mercury 90hp, but I thougt the mid and top perfomance would be great...isn`t that so? We got a Mercury 60hp (100kg) today and the Yamaha 90hp (120kg) is 20kg up, so I think that`s acceptable for the extra 30hp. But if we go for the Mercury inline 6 90/115hp (150kg) the weight will increase a good 50kg and I`m not to happy for gaining my little boat (14 ft and 250kg) all that extra weight. Please correct me if my assumptions are wrong...!

Back to the Yamaha 90hp; I spoke to my local boatdealer this morning and he contacted Yamaha here in Norway to run a check on the serial number, and they replied that the motor was not to be found in their system. So this motor wasn`t sold new in Norway and had never been serviced by a Yamaha dealer. I have contacted the owner of the motor by sms with this information and will be waiting for his reply. The Yamaha motor is in a very good condition, but the price should reflect the modelyear, if you know what I mean.

My Shakespeare Clubman is in a very good condititon and I would like for my new motor to be the same, with a known history. The owner of the Yamaha claims that the motor is a 1998 mod. but by the pictures of the motor it looks to be 10 years older. If you look at the cowling and the color of the motor...is this really a 1998? I`ve posted a similar thread on Screamandfly - mcyama indicate that the motor could be a 2001 mod (Z), then I`m even more confused (maybe it`s a Frankenstein...or stolen!).

Anyone out there got a clue...? Serial nr. 6H1L 351205 90 AEZ

Take a look at the pictures and you`ll see why I`m confused about what year the Yamaha 90hp really is.



These three motors are all 1989 models First cowling: 1985-1993 Second cowling: 1994-2000

Can you post a close up pic of the id plate? There is a single letter in the corner of the plate. That letter denotes year of manufacture.

Sorry, but this Yamaha motor is located in a town 255 km from where I`m living so the only information I`ve got is this serialnumber the guy who is selling the motor sendt me.

But I`ve got a respond here i Norway about the serialnumber 6H1L 351205 90 AEZ, and this person claimes that this motor is a 1986 model. After doing a little researced on the internet, I think that is correct as Yamaha apperently made the Yamaha outboard motors in this color and dekal combination in 1985-86 and 87.

I called of the deal on the Yamaha motor today. Now I`m looking for one of the last Mercury 115hp inline 6 instead! (1982-88) Wish me luck...!
