Default Yamaha Denied Warrany Claim For Cracked Cowlings!

I have twin Yamaha F300s that were brand new in October 2017. In August, each motor developed a crack on the port side of its cowling between the “M” and the “A” in Yamaha. Yamaha denied the warranty and claimed that the motors were impacted. The motors were never hit or impacted. Plus, due to the location, it’s be impossible to hit the same spot on both motors. Anyone else dealt with this... Yamaha’s warranty department stinks! Both motors, same crack location, wear on inside of both cowlings in same place from rubber spacer...

OP, I am sorry for your situation.
Couple of things to look at and understand, then lets see if we can get this figured out.
1) We have serviced literally hundreds of these through the years, and in that time, I have never seen an F300 with twins and two cracks like that, and we do singles, twins, trips, quads. I have three on my own boat, never seen the issue.
2) Those motors where painted by someone other than Yamaha, so, Yamaha COULD take the stance they have been modified. COULD. If that's the case, go to the boat manufacturer.
OK. Something made them crack, they didn't just do it on their own. Getting in the boat? From a ladder or dock? Lines across the stern? Could another boat have hit them. And yes, I know one is on the inside of the stb engine, but cowlings can get swapped.
The cowlings fit "snuggley", however, you don't "push" them down, they "fall" into place. Do these have to be pushed down?
OK, so say, they are "defective", couple of things to understand.
1) Since the Yamaha dealer has run out of options, it's up you and the boat manufacturer to prove it to Yamaha. Take good pictures, of the cowling, and where it hits on the engine, and not close ups, take some where you can see where everything is. There is no "spacer", so see where it is hitting on the engine. You can email the pictures to me. oparker@parkeryacht.com I will go out to my engines and see what is possible it's hitting.
2) IF Yamaha gives you cowlings, they will be GREY, getting them white will be on you or the boat manufacturer, along with those decals.
Where are you located, maybe I can look at them for you, if I can't, I will do what I can to assist from here.
Yamaha isn't perfect, but if you show them something and can prove it, they do come around. Knock on wood, we have never had a claim rejected, and some are FAR out of warranty, and some certainly are not Yamaha's fault, you just have to supply them with the documentation they require.

Can it hit the side of the Eurotransom when tilted?
Looks like that to me. Then again, maybe a reflection.
Are there soft covers on the motors for storage?

That’s just a reflection. Plus, have the same crack on both motors... Saw the cracks after ran back from Bimini. No covers on the motors.

The probability of one Yamaha having a defective cowling is very low.

The probability of two Yamaha's having a defective cowling is very, very low.

The probability of two Yamaha's having defective cowlings at the same time, in the same general area, is all but impossible.

A crack in a cowling due to a manufacturing or materials defect would be very small if discovered soon after the crack began. The size of the cracks as seen in the photographs would lead anyone experienced in fiberglass defects and external damage to believe the latter is the situation. Looks like an insurance claim to me.

Have you looked on the inside of the cowling? Is it cracked all the way through? Can you see where it has hit the engine?
Is it possible the primer and paint has cracked? Who painted the cowlings?

The engines were new last year but did you buy them used?

Engines are brand new. Looks like the port side spacer caused the cracks.

It would seem equally odd to me that an impact could affect each motor in THAT location at the same time. I would think the inboard side of the affected engine would be very well protected. If it was impact damage, wouldn't there be a sign of impact other than a crack? Kinda like when a rack cracks a car windshield, the rock leaves an impact mark.

You can’t crack both motors in the same place, Bc when the motors are turned, one protects the other... Plus, there’s no sign of impact... oh, and the motors were painted by/for the boat manufacturer.

I would go to the boat manufacturer or whoever serviced the engines last. That doesnt just happen

It looks like someone made a mistake.

I would call and ask to speak to the person in charge. Where did the engines come from? The dealer and if a new boat, the manufacturer should be saving you this grief.

Is that bondo around the crack - maybe the dealer cracked them and repainted them to disguise the accident.

I swear there was a thread a few months ago with a Yamaha cowling that cracked in the same exact location.

Do you store the boat at a marina were they use a fork lift? Your cracks are in the same location as mine, my marina pulled my boat back to hard and it hit the fork lift enough to crack both my cowlings.

Just a thought.
