Help - starboard won't start

[Adrian @ JB Solutions]

Was out for almost 10 hours on Sunday and no issues. the Starboard seemed to run a few 100 RPMs less than the port. Not sure how normal that is - but everything seemed fine otherwise.

@adrianp89, could your dealer determine if was salt water or condensation? I'm wondering if you may have had a head gasket breach due to an engine overheat.

 

[Adrian @ JB Solutions]

No they could not - they think it may have been from when I was returning back to the boat landing, since I was going about 12mph back. I know better now.

@adrianp89 glad to see that you're up and running again. I'm confused on what the original issue might have been though. Any explaination on why the engine initially shut down, or wouldn't start?

 

[Adrian @ JB Solutions]

They could not find anything wrong - no codes stayed in the computer history. I am clueless as well.... but it runs now and it is documented.

 

[Adrian @ JB Solutions]

Well the issue happened again. I had to take up for the 10 hour service anyway, so I took it up on Monday. He said something is too "tight" inside the engine and they are waiting to hear back from Yamaha. He said they want to just put in a whole new motor but have to wait to hear back from them first. Any thoughts guys? Kinda sucks on a new boat - but I guess it is what it is.

first let me agree - it stinks when you have something new not work right
second - it really stinks when you have something simple like a broken or intermittent connection cause a no start situation and it gets compounded by running back in on one engine and getting water/moisture in you cylinders, now confusing the problem even more,

Is it still cranking fine and just not getting ignition?

I have to wonder about your mechanic, the answer sounds like so much BS we here from dealerships, I hope that he realized your ignorance on engines and was just trying to dumb it down for you and there is a very viable explanation that he is confident about.

That being said, I can't think of how something "tight" in your engine would cause this problem and it's very curious that they are going to put a whole new engine in for you under warranty, you're a lucky man.

 

[Adrian @ JB Solutions]

Correct - cranking fine but no ignition. These guys are supposedly the largest Yamaha Jet Dealer in the country, so I hope they know what they are doing lol. I will call Tuesday to see if there is a status update and to get a better idea of the issue. I'm no engine expert but I would say I also know a lot more than joe schmo - if they explained the issue I would understand. I hope to speak to the other guy that typically works there, the guy I spoke to has a pretty heavy accent so I just let it be. In my opinion it sounds like an issue getting spark.

If I had a dollar for every time I have heard " We are the largest......." LOL.

This is a TR-1 motor, right? In skis, there were some reports of TR-1s corroding wiring harnesses, ECU problems, solenoid problems - but no issues with the engines themselves.

[Adrian @ JB Solutions]

Correct - it is a TR-1. Would these issues occur a motor with only a handful of hours?

 

[Beachbummer]

It is very rare. Also, I suspect nobody here believes the dealer line. As a fake mind reader I can guess most folks think it's an electrical problem from the description of symptoms.

 

[Beachbummer]

Although, The dealer did have access to the boat to check it out, so one would think they have a better chance at figuring it out.

 

[swatski]

Correct - it is a TR-1. Would these issues occur a motor with only a handful of hours?

Actually, possibly - yes. That's why I decided to mention that - people have had some wiring/harness issues related to corrosion in salt water with TR-1s, with relatively very few hours.

Keeping it short - the cylinders are loosing compression and leaking. (Or something of that nature). They needed my authorization to do a tear down. I told them I want a new motor as this point. Do you guys have an idea what could cause that?

I just saw this and honestly it sounds pretty weird however I personally have had engines refuse to start because the throttle positioning sensor was not working properly so I tried moving the throttle back and forth and that would reset it, also the kill switch could be malfunctioning, But the dealer needs to represent your interests and get Yamaha to fix the issue. limping back in at 12 mph could have put water in the engine but not always it depends on the position of the impeller but having it fail to start was the original issue and if you drove it back that is not your fault unless there is a warning sticker telling you otherwise , you are not a mechanic and have no reasonable expectation of knowing these things , a reasonable person would do exactly the same thing tow it in or run on one engine . that is expected. It is a new boat and it should operate like one.

 

[Beachbummer]

From something too tight to losing compression...

Any chance the is another dealer in the area that could take a look before they start breaking down the engine? Maybe they are good and just explain things suspiciously?

It does sound fishy to me.

 

[Scottintexas]

without the wording the mechanic used it's probably to many possibilities or impossible to know what he's thinking,

I would think if it won't start at all that would mean all the cylinders don't have compression, if only one or two were bad it would run just very rough,
What would make all the cylinders loose compression??? that would lead me down Jeff's path posted above,

Also, I've not dealt with warranty work before but if it's covered by warranty why do they need your approval to tear down?
I would triple confirm you're not going to be on the hook for the charges,

I think you would be incredibly lucky for Yamaha to approve a new engine

 

[Cobra Jet Steering LLC]

Yamaha won't replace the engine unless it costs less than repairing yours it seems like your original issue was probably a simple one and it eluded the person who looked at it but you took it to a dealer and it continued to occur so tell the dealer he has your permission to do whatever Yamaha authorizes him to do under warranty. But you want to be in the loop and be informed.

 

[Ancient canoe]

I don't know what tear down an engine ensues, but seeing as they have no clue at this point, I would guess by the time the dealer invoices Yamaha for labor you'd be getting pretty close to the cost of a new engine.
