Just as a disclaimer (I am not making accusations against any location) Just asking a question to see if there may be something to my issue.

On December 20th me and a buddy hit Lake Fork for some fishing. We gassed up and launched at the Minnow Bucket. Almost immediately when idling away from the ramp both me and my buddy noticed a sound coming from the rear of the boat (rattling / knocking) but it was undiscernible and I chalked it up to my Talon vibrating and making noise. I did not notice any performance issues initially so I brushed it off. We ran to Little Caney and fished for a few hours then headed to Glade. On the way to Glade I noticed my RPM’s dipping a bit but again brushed it off since overall the boat seemed fine.

After a couple of hours in Glade I go to leave and while idling out to the boat lane the (knocking / rattling) returned but louder. I placed the motor in neutral and it seemed to quite when not under load so I again assumed it was the Talon bracket vibrating. I jump on pad and make it all of about half a mile and the RPM’s spike, then dip, then spike again and the boat dies. Power head blown. Piston on cylinder #1 came apart and knocked a hole in the block.

This was quite shocking and disappointing being that my 2011 Skeeter ZX225 with a Yamaha HPDI VMAX Series 2 225HP only has 365 hours on it and has been very well maintained. What made it even worse was the warranty expired in June on the power head so I was 6 months past the warranty period.

I reached out to Yamaha to see if I could get some good will assistance since I was only 6 months past the warranty and I have all the maintenance records. The repair shop pulled all the info from the computer and took pictures of the damage. Injectors and all mechanical pumps cleared as operating as designed. Yamaha determined that one of 2 things caused the failure.
1. Bad gas
2. Overheating
I’m 100% certain it wasn’t an overheat as the motor was pumping water out just as it always has and had only been running for 3 – 4 minutes before failure. Plus, I had just had the lower unit serviced a month prior with new impeller installed and the boat had been out several times since with no issue.

Being that the boat had been on the water the day prior with zero issues and the fact that me and my buddy both noticed the strange noise immediately after gassing up and pulling away from the ramp. I have to wonder did I get a load of bad gas? The boat had been ran twice on the previous top off with no issues.

Wondering if anyone had anything similar or heard of anyone having issues with gas from the Minnow Bucket around that time? We have pulled a sample from the tank and have sent off to be tested so I will know for sure in a couple of weeks.

Again, not accusing them just looking to see if anyone else had an issue. May have been just my bad luck or Karma coming around to pay me back for something.

What are you saying was the "bad" with the gas???


Did you have the gas tested in your tank???

Engine overheat will show up on diagnostic report. That will eliminate it down to only one thing left. I've never heard of this happening, but with the way these engines blow, I wouldn't put anything past 'em. Keeping my fingers crossed every day.

So sorry to hear of the problem......hope some good will comes your way.

HPDIs are known to blow cylinder #2 even with good gas.....no way to blame this on gas

Not sure how to put a snip it in but if you read above it states "a sample has been pulled and sent for testing".

Again, I am not saying it WAS definitely bad gas. I am simply looking for feed back to see if anyone else had an issue. If there was bad gas I am sure more people than just me would have been effected. The diagnostic from the engine showed no overheat. Yamaha may have just thrown bad gas out there as a way of shining me off and hoping I would drop my request for good will. That's why I had the sample pulled and sent for testing to either eliminate that or confirm it.

That is actually similar to the experience I had when my Yammy 250 SHO threw two rods and cut the power head in half. Mine ended up being covered under warranty, but like yours they couldn't figure out what caused the failure. The only difference was mine went faster than yours. I ran from Eisenhower to the 377 bridge, fished some, moved up to Buncombe. Everything was fine until I was about to the Preston Peninsula. I lost RPMS, and overheated. Killed it, restarted to check water pressure and the knocking began...

I get gas at the minnow bucket (pump on the water) often and bought gas from there the same week. I ran it through to empty and filled up there 1-2 times since. So far no issues.

If you heard knocking and your RPM’S was going up and down it sounds like a bearing was going out, I had one that did that.

I've gassed up at Minnow Bucket and fished out of there for years and never had a problem with the gas.

Regards,

Bart

What hour mark did you have the high pressure fuel pump replaced or rebuilt?

What hour mark were the Fuel filters replaced all 7 of them

Also common misconception is that if your motor is peeing it’s getting proper water pressure. just because you see it peeing does not mean the proper water pressure is being made, example being you can still have good water pressure and not See it peeing if the Little port is blocked because that port is just a T off the waterline so just because you see it peeing does not mean you have sufficient water pressure

I would think that it would take a couple of miles for the new gas to even have gotten into the motor?

The high pressure fuel pump was replaced at 260 hours and tested at regular intervals since. I had a full service done on the motor at 320 hours (has 365 on it now) which included ALL the filters, new plugs, a compression test, and a fuel pressure test. The boat is equipped with a water pressure gauge and there was no drop off or change in performance there. The engine has been disassembled and there are no issues with any bearings (initially I was thinking the same thing when it locked up). The #1 cylinder's piston came apart at the top and knocked a hole in the block.

This came out of the blue and I am really struggling with what happened. There was nothing on the diagnostic that led to the cause and Yamaha made their call based on the condition of the piston that came apart. Being that it was out of warranty they were not liable to help me anyway but it would have been nice.

What would be even better... would be if I knew that the $7K on a remanded power head I have to shell out was going to be money well spent. And that that I knew 1 year down the road just past warranty period it wouldn't happen again with no explanation as to why.

I just went through the same thing last year. First day on falcon, 600 miles from home. mad I sold the blown motor to a guy on bbc for 3200 then bought a new 4 stroke.


It’s always something with a boat.

Take it from me. Take your boat to Fun n Sun with the blown motor. Trade it in on a new one. They’ll make you a fair offer on your boat with the blown motor.

It’s a blown motor this year, lower unit next, ect.
