Default i need help and advice pretty quickly. Yamaha F150 balacer has shredded.

2007 Angler 2600 with twin 2006 Yamaha F150's

I just got the call from the mechanic letting me know that my balancer is gone, and the fiber material is all through my motor. The motor is not blown as i had it out this weekend and noticed that one of the motor's was running very low oil pressure. He called YAMAHA and they said the the motor would have to be 100% disassembled to make sure that every piece of the material is cleaned from the engine. I will need a new balancer and a new oil pump. 3000.00 dollars worth of work at least.

Here is the other part of the issue. We are supposed to leave for the keys in 10 days for our keys vacation. The mechanic says he is just to busy to do the work and my motor is totally taken apart and has to be taken apart even more. Should i see if another local mechanic can get it done before my vacation? or just face the fact that after 6 months of anticipation my big dolphin fishing trip to the keys and snorkeling for the kids is shot. Money is an issue as it will be tough just paying to fix the motor after spending so much getting the boat and trailer whipped into shape after what seemed like a few years of not being taken care of.

Should i ask him to box up my motor and look for a mechanic who can do the work before the 6th?

Has anyone been through this? Is there a way to flush the system without complete dissasembly? Can this be done another way besides disassembling the entire motor?

The only way to be sure that all debris is removed from the motor is to complete dismantled the block and heads. Even then there is the possibility of not being able to find and remove all of the debris.

If this is not done and debris remains, it can cause a catastrophic value of the motor. Think of the debris being a blood clot in your leg. If the debris stays out of the blood/oil flow system maybe no harm no foul. If the debris breaks loose and blocks a passageway you and/or the motor can be killed.

Been through this one. You will need to remove the power head and also pull apart the mid section to get the sump clean. It is not overly complicated to do and I don't remember needing any special tools. The hard part is that even with the power head off you can't get the oil pickup properly clean without stripping the mid section. Again, not overly hard, but takes extra time. In ours the mesh filter on the pickup was distorted by the excess suction, and a replacement was not available in the time we had so we made a modification to fix it.
We stripped ours down and cleaned all the balancer shredded bits out of the sump and oil pickup. Checked the oil pump but it was still OK. The next item after the oil pump is the oil filter so you would have to get very unlucky to have any debris in the oil passages. We had none in ours between the oil pump and filter, but there was debris in the filter. New filter fixed that. Stripped the balancer and cleaned the last of the teeth off the fibre gear so the balancer won't run anymore. Whole job cost maybe $150 or so for some new gaskets, filter, oil etc and took around 6 hours for two of us I think. Might of been 8 hours, but I seem to remember it was less than a days work. You can't tell the difference between the engine with the balancer and the one without when they are running (twins), and as far as I have heard there is no guarantee that Yamaha's replacement balancer won't fail, so I feel better with it gone. New balancers aren't super expensive though if you fell better with it. Changing the balancer is only an hour or so of work. Done another 100 or so hours since doing the fix and oil pressure is same as it's twin and engine runs perfectly again.

I think this is you best bet, we rented a 23' angler last year with outriggers for 1750 for a week.

Talked with the mechanic, he said he has changed out probably 100 balancers but has never seen one go bad. "im just lucky i guess". Yamaha told him that the engine should be torn down to the last bolt to make sure that all of the fiber gearing is removed. the told me he was just to busy to do this before we leave for the keys in a week. I was pretty heart broken.

He called me back about 2 hours later and said that the motor itself is as clean as a whistle and that if I sign off on it he will clean the sump, and the screen, change the oil pump and put in the new balancer. This will save 10 hours of labor and it will be done in time for our vacation. I know this is a little risky but from what i have read online this is what most people have done in the same situation with good results. Hoping and praying for the best. He already has the motor torn down to the midsection, just waiting on the parts to put it back together.

P.S. Shame on Yamaha for such a bad design. im a big fan of their's, and always have been . We have 2 Yamaha MX bikes at the house and a yamaha golf cart. Love there products but they plain and simple failed there customers and did not do a recall this bad design.

Didn't you have a previous thread about worrying about low oil pressure before this vaca?


Did you keep pushing motor?


I would rent a boat and let the mech do it right

yes, i started that thread after i saw the low pressure on the guages but i did not know the reason for the low pressure at that time. I started this thread after getting the confirmation that it was the harmonic balancer. I have looked through some old threads and it looks like most people have done what we are doing. Even the Yamaha mechanic thinks that YAMAHA is going a little overkill with taking down every bolt on the motor. I hope it doesnt bite me in the butt! We not going to spend 2k to rent a boat in the keys when we spent 25k buying one and another 10k getting it up to par for a keys trip. WE WILL keep a close eye on the oil pressure on that motor though.

Your lucky. We had one go out and tear through the engine with no warning with only 19 hours on a brand new motor. We were running one day and all of a sudden lost the engine. No overheat, nothing. Took it to the dealer and they couldn't see anything wrong by the computer either. Torn into it and balancer shredded. They had to tear out and replace everything but the lower unit. I wanted a brand new engine but either the dealer never pushed or Yamaha wouldn't go for it. So next best thing is what they say they did. We now have 600 hours and has been flawless every since.

Its just one of those things. It happens every so often and not enough to warrant a major redesign

Good luck with it, if I were you, I would swap out the other balancer before the trip.

I'm no lawyer, and not even a litigious person, but it sounds like a class action situation to me.;? BTW, my last 4 engines have been Yamahas, but no 4 strokes.

Put yourself in Yamaha's position. They say to do only what your mechanic is apparently now going to do. A less than perfect repair if you will. Customer has a single powered boat that he takes 100 miles out in the Bering sea. Motor fails. Customer dies. Customer's family then sues Yamaha for not adequately specifying how the motor should have been repaired. Yamaha settles out of court to avoid a costly long drawn out law suit. We all then get to pay for the costs of that suit in the form of higher motor prices.

Oh, how about a gas turbine failure on a twin engine powered long range air liner that flies over the Pacific. Is it acceptable to just patch up a motor with maybe a marginal fix or should the motor be gone through with a fine tooth comb to make sure that the probability of a future failure is nil? The air liner probably has a better chance of getting home on one motor than will the single F150 driver out in the Bering sea.

I called my cousin who bought a hurricane last year with an 08 Yamaha F150. I asked him if he had heard about the issue with the harmonic balance on his motor and he of course said "what harmonic balancer issue". This is a lot of the problem.

Where can you buy a hurricane? Texas needs one, sometimes, but not right now!:D

It might have been updated but still and issue. We were told they expect 1 in every x amount to fail.

As for what the mechanic wants to do. You need to see if he plans to stand behind his work in the event that the motor fails again with the issue due to him not abiding by yamahas recommendation. If he will then let him fix it, if not I suggest you get it done by the book

I just replaced the balancer on my 150 after reading THT, and before any damage occurred. What I discovered about Yamaha notices... you must take your engine data to a licensed dealer and have them transfer the engine data to your name. This was my case after owning the boat for over 5 years. I bought the boat from the original owner who did not forward any notices to me. I never thought to transfer the engine data. This cost me for the replacement, don't make the same mistake.

I wouldn't panic about a full tear down unless you ran the engine a lot after getting the oil pressure alarm. The first thing after the oil pump is the oil filter, so you would have to tear up the filter before getting any debris into the oil galleries, bearings etc. We cut our filter open and you could see the shredded plastic as minute little pieces, but they had been pounded into tiny specs by the oil pump so I can't even see how they would cut the filter fabric to get through it. If you ran it long enough I guess you might clog the filter enough to 'blow through it' with oil pressure, but I think that would be unlikely. Do what your mechanic is doing and I think you will be good to go.

Hey BigFish,

Same thing happened to me last September. I had an oil pressure alarm coming back into Mayport from being offshore all day. I instantly shut the motor off thinking it was over temp . restarted and no alarm, idled to the ramp, flushed at home. still no alarm, checked the dipstick & drained the oil. Pulled the balancer from the front of the motor & saw half of one of the gears wiped.

Gregg over at Dell Marine said it would be bit of a gamble, but had done it before with a majority of success. He pulled the powerhead, took apart the mid . Labor was more than parts, but still less than another motor. I brought the boat over to him on a Thursday and picked it up on a Tuesday. I have always worked on everything I own, but I was working so much I just wrote it off as I needing to work alittle more OT.

That was almost a year and probably 45 hours ago.. no problems
