Default 2007 Yamaha F250 Exhaust Issue

Hi All,

looking at a a boat this weekend with twin 2007 F250’s.

two questions:

1. Did the 2007 F250’s have the exhaust issue?

2. without having the engines scoped, is there any way to examine for exhaust corrosion issues? Someone had said something to me about inspection plates. And

3. anything else I should Be on the lookout for with this year engine?

thanks!

yes they can have the exhaust issue
Scoping will give you some indication but pulling the powerhead is the only way to get a good verification

Following. I have the same pair of motors. From my research i have found that in fact they do have an occasional corrosion issue but not as often as the earlier 225s. However, I love mine and they run great. IMO some of the best engines yamaha has ever made

The 2007 F250 isn't a likely candidate for dry exhaust corrosion.

Can it happen? Sure it can. Just like a meteor can fall from the sky and hit you in the head while you sleep in your bedroom. (I exaggerate a bit ..... but you get the idea)

Yamaha had fixed their metal problems by early 2005.

spot on with my research. Call Yamaha with the serial numbers and they will tell you if they have the updated metallurgy.

i guess my 05 F250 didn’t get that memo.

An 05 F250 is not necessarily an early 2005 F250.

Some 2005 F250's were first built in 2004.

The OP asked about an 2007 motor. He is most certainly "in-the-clear" from the bad metal problems associated with the 2000-early 2005 F225's and some F200/F250's

Your 2005 is a different case with different circumstances and not part of the original question.

”Yamaha had fixed their metal problems by early 2005.”

I was referring to this post.

I scoped my early 2007‘s and didn’t see any corrosion just pull the foot and stick a camera up the exhaust and take a look. You should see pitting and I didn’t see anything . There was dry salt and that’s about it. I say this because it’s not hard to check, but just because mine are good doesn’t mean your in the clear.

My oil pan rotted and you can’t see that from a scope. The only true way to check is removing the powerhead.

I have a pair of 2007 Yamaha F250's on my boat with close to 1500 hours on them. At about 1250 hours, One had issues one did not. Both looked good from the bottom. I had the occasional low idle overheat issue. I dropped the lower unit and connected a hose to the pick up tube. A stream of water came out of the dry exhaust section. The complete repair was $1700 which I don't feel was that bad. It runs like a champ and couldn't be happier with them.
I would not be scared about buying another pair either. I would just be aware at the possibility and expense of getting it repaired. They are great motors.

You can NOT rule out the presence of exhaust corrosion without removing the powerhead.

You CAN confirm that an engine has exhaust corrosion by removing the lower unit and looking up the leg.

If it looks excellent with a naked eye view up the leg using a flashlight then you may or may not have exhaust corrosion.

If it looks anything less then excellent when you look up the leg with the naked eye using a flashlight then you can guarantee that the engine DOES have exhaust corrosion going on....

The point of my post is people shouldn’t be under the assumption that a scope tells the whole story.

I have a pair with 1900 hours and they have been bullet proof so far.

Flounder,

I COPIED AND PASTED BELOW, MY RESPONSE TO THIS SAME QUESTION BACK IN NOVEMBER. BASED ON MY EXPERIENCE I WOULD MAYBE BUDGET $2000 REPAIRS JUST IN CASE? BOAT HAS SINCE SOLD I FELT VERY CONFIDENT THERE WERE NO ISSUES WITH CORROSION




I have been dealing with this issue over a period of (2) years and have been wanting to take time to get my story on here somewhere. It's kinda of long but I am laid up with a bad knee for the weekend so maybe it will help you make your decision?

I bought a boat in September of 2017 with a pair of F250s that were manufactured 11/06 and had 430 hours on both engines. Before buying the boat the only checking it I did was test run it maybe an hour and took it to the GW Dealer to check compression, check the lower unit grease and scope for corrosion on both engines. Engines ran great and got a clean bill of health(no corrosion).The owner offered no maintenance records other than his word that the engines had been great and he had them serviced as recommended. I did not know when they where last serviced so I trusted his word and ran the boat until the "100 hundred hour" service notification came up on the gauge at 480 hours. I took the boat to a non Yamaha authorized mechanic that had serviced my stuff in the past and I trust him. Had him complete all the Yamaha recommended service for 500 hours and 10 years old(this was in March 2018) and cost about $2400 and he advised me at that time that the starboard engine had exhaust turner corrosion, needed to be replaced and he would do it for $1800 to $2000. He called me to look at the exhaust so he could show me the corrosion he was seeing. I drove two hours to look at it and he did not even have a bore scope. He shined a flashlight up into it and tried to explain what he was concerned about. To my untrained eye I could not see anything that looked like any of the pictures I had seen online as I researched it. So I could not see it and his response was that I should not take a chance because it could eat into the powerhead and be a much bigger problem and the only way to be SURE it is to pull the powerhead.

So I left the lower unit off and carried back to the GW dealer and asked them to give both engines a second look(six months after they originally inspected it). They stuck by their originally diagnosis and said BOTH engines have no corrosion issues and "as a matter of fact they look exceptional". So being a little skeptical still I said leave the starboard lower unit off(the bad engine). They did not charge me anything, sent me a video of the scope and offered to tow the boat to my house there in town and they did. Now you would think they had convinced me I was good but the boat is sitting in the driveway with the lower unit off so I call another Yamaha certified service/dealer there in town that has a great reputation and tell them that I have pulled my lower units and BELIEVE that I may have a corroded exhaust tuner on my starboard engine and ask how much to run by there and scope it? They say $100,great please do it at your convenience; Two days later they call and say I got good news and bad news, good news is there is no corrosion, bad news is you paid me $100 for nothing, which to me was amusing at this point!

I put the lower unit on and ran the boat until I hit the next 100 hour service at 580 hours in October 2018(7 months later). I have the boat serviced by my GW dealer and roll on with it. June of 2019 I have a person interested in buying the boat and we agree on the price and he wants to have the engines checked out. Just so happens he chooses to take it to the service center that I had give me a third opinion back in March of 2018(15 months prior) when they gave the starboard engine a clean inspection. They start the inspections for the buyer and call him to report corrosion in BOTH engines so he stops them and calls me. I called the shop doing the work to get the scoop and they inform me that both engines need exhaust turners and the starboard is worst than the port! So now I am really perplexed??? I remind them that they scoped the starboard a little over a year prior and the guy recalls scoping the engine and he does then seem to back peddle a little and states something like "well they are not going to go out on you tomorrow but the starboard needs replacing now and port can just be inspected every year". I had them put the engines back together and took the boat back to the GW dealer and told them to replace both tuners. They said it would be about two weeks before they could start the work. About two weeks later they call and advise that they have pulled the starboard powerhead and there is no tuner corrosion at all! I leave work and drive to go see for myself and there is absolutely no corrosion and this is the bad engine. They said "we do not want to waste your money so we can put it back together and you will be $350 to $400 into it or we can complete with the new tuner kit for $1800 to $2000". I had them go ahead with the new one just to say it is done and had them scope the port side again just for reassurance!

Long story I know but the point is trust who you are working with and I would get another quote. I am in NC and the going rate now is $2K give or take.

based on what I am reading you have a pair of 2003 f225s and you know that one of the two has had the turner kit installed. If the engines are in otherwise good shape it may be worth a couple thousand to repair but not if you are going to repower anyway?

Lots of things to consider though and you would really have to know the complete history of the engines to make a sound financial decision and even then it is a crap shoot because fixing a Yamaha outboard is expensive!

Do you know if the timing belts and tensioners have been change?

Again, if all the recommended maintenance has been completed these engines are good for thousands of hours and outside of the corroding exhaust tuners have a great reputation

Mine ran bullet proof too till the day I turned the key and discovered my oil pan rotted. There was no warning or sign
