Yamaha ?
 

looking for opinions , pros/cons on a 1998 Yamaha C115 v4 two stroke . Motor has undeniably been well taken care of & is in exceptionally good condition for its age . Just looking for any known inherit issues good or bad with this particular make/model.

engines remained unchanged for most of their life. solid, simple, bulletproof technology. I'm restoring an 89 20cc and i just bought a new in crate 2005 Yamaha 115 2 stroke. I was ready to pull the trigger on a Zuke 140, but this 115 came long and im stoked about it.

I think most say the performance on a 20 is adequate although not a speed demon. I don't think anyone will have any negatives to say about that engine.

No Sir!! No negatives...... pretty much "bullet proof" as you said! "New in the crate 2005" , you're killing me!!! I know someone who's looking for a new 115/130!!! I'm doing all I can do to find a "new in the crate" 90 hp two stroke Yamaha......they are getting very hard to find 'cause of the new regulations!!!

Thank You Mr. Government!!

Ditto what the other guys said. DO a compression check and if the numbers check out it sounds good.

Thanks guys, good to hear such reassuring positive feed back. BTW the motor is on a pampered well cared for turn key original 1975 seacraft 18' that has been kept sheltered all its life and is in amazingly good condition . No soft sposts, no gelcoat cracks, and a solid transom ablate its 20". May or may not deal with the low transom in the future, we'll see.

Good motor. There would be some thing's maintenence wise I would look at.
I saw a 90 2 stk down here or craigslist the other day. Thought it was brandy new, it surprised me.

Hummm.....the 90 Yamaha on my Hewes is just so damn dependable I figured I could just buy another one "new in the box" store it in the garage for a few years and do the old "plug and play", replace when mine wears out, however the one I have just keeps on going, and going, and going. The big issue/problem is the fuel usage on my carbed engine versus that on a new four stroke....against the weight difference, plus the $$$$ investment on a new four stroke, plus all the other stuff like controls, guages, etc. I thought I would "beat the system" and just go back with the old engine technology on the cheap but the government regulations make it hard to do. The old ones are not easy to find and when you do the seller knows what it's worth and asks an arm and a leg! It's hell to be poor!

Yea, I ran one of those 90's on a 15 whaler for years, great engine, but loves her fuel. Take care of it and it may outlast you!
But, you never know, keep haning in there and the new Yamaha's might surprise you, that new little 70 is kick a--, so maybe the 90 is next? :-), in either case, I don't think they plan on messing with the rigging, at least not down in the smaller engines.

I am pretty sure those C-series motors are pre-mix. That could be a pro or con depending on your views on oil injection.

Yeah, I saw an ad for the "new" 70hp, did not look at it real hard. Would be interested in the 90 for my Hewes if it comes along. At $4 plus for gas my old two stroke is killing me, HOWEVER you can buy alot of gas for $8,000, or whatever the price of a new 90hp engine is.

OK...it got the best of me, had to look it up on the Ymaha web site. The F90 is a smooth and over weight 366 lbs, however the new F70 is 257 lbs, my 1998 two stroke is 281 lbs. Hummmm....if they get the F90 in the same general weight range as the F70 they will have a winner!!!

They might, they have some things in the pipeline. Next one to pop will be a redsigned F150, then probably a new F200.
You are right though, you can buy ALOT (for your motor) of Go Go Juice for 8k.

$8000/$4.25 = 1882 gallons fuel. Say you burn 15 gallons per trip that's 125 trips. :)

Yes Sir Strick!! That's the same "Jethro" math I use. Like I tell dealers at the boat shows with the "greatest deals available" on new engines, I can buy alot of gas for that kind of money, however If I stick a rod out the side of the block, or it starts giving me trouble, we'll talk.

The $8k is for a 90hp, when you go up to the 250hp for my 'ol SeaCraft the price of poker goes crazy. Seems the 250hp Yamaha is around $2k - $3k higher than an e-Tec so that makes my decision easier. If I used it alot, like two trips a week on a regular basis, I could justify the expense before something goes wrong with what I have. Until then I'll just burn more gas.

Being poor sucks.

Seeya

I'm poor and a tight ass ! :)

I love my little 1998 Yamaha 130 saltwater series. When it dies I may get a 4 stroke but for now it pushes my 20 cc just fine. Off to try my new electronics Simrad NSS8 with structure scan!

After three days of fishing last week the gas bills on my 90 two stroke are killing me. When do you hear the new 90 Yamaha might be available. This gives me time to work on the wife.

Yup they are premix and they don't have a freshwater flush. The only way to rinse them is to use ears. Hope you're keeping her on a trailer. Bullet proof motor though, easy to maintain since there is nothing to them.
