Look what stopped my Yanmar

[MarkJ]

One of the worst sounds to hear is when there is no sound when the engine was making a nice sound but no more, suddenly.

My ultra reliable was charging the batteries when it died. Sounded like fuel, but it restarted immedietly and ran fine but I did a filter change next day after it died briefly again, and there was fuel in the Racor and final filter, hard to blead, though. Started again fine and did 2 hours up to 2,500rpm then went for a 5 nm run where it died again.

Racor half full, so ripped out the fuel intake pipe from the tank and look what I dug out of it!
Previous owner must have had a sender problem and replaced it and lost the whole gasket into the tank!!!!!!!!!!!!! Ive had it for 5 years so its been swiming around in the tank for a loooong time.

The gasket still looks new.






Stuffed if I know how it could have fitted right up the pipe.

Don't you just love POs and some of the wonderful things they do to boats. There are some exceptions but so far I have found very few.

Looks like the "O" ring that seats the fuel filler cap. Have you checked that?

[colemj]

Looks like rtv silicon to me.

you and me both brother. If our PO ever showed up at our boat again, I'd have to race the wife to see who gets the privilege to strangle him first.

These days, if I find something on the boat that says WalMart or Harbor Freight on it, I pretty much rip it out and order the right part whether it's still working or not.

And I do try to remember that I am someone's PO...someday...and the answer is to do it right the first time, and to fix the temporary fixes at the next opportunity. It's scary how often temporary fixes become someone's idea of a permanent solution.

Mark,

I had a similar problem. My engine would run fine, but wouldn't go above 2600 rpm.

The problem turned out to be an obstruction in the pickup tube in the diesel tank. Some material from the plastic fittings in the top of the tank had fallen into the tank. It looked like they had cross-threaded the fittings, and some curls of plastic had been stripped off. Once I dislodged the plastic pieces by ramming a piece of wire through the pickup tube, everything was fine again.

Isn't every owner eventually a PO?

This S.S. nut found its way into my Westerbeke, causing the piston to crack...you can see where it was found 'welded' to the cracked aluminum piston...so where do it come from? Westerbeke used a piece of threaded rod to attach the air cleaner, I can only suspect it came off the inboard end of that rod...on several occasions the air cleaner has vibrated off and was found lying beside the engine...

In defense of POs, that thing could have been there since the boat was built.

I remember bringing a new 77' sled back from a race down to Manzanillo MX when it started to suffer from fuel starvation and would not rev up very high. After a couple of hours of motoring slowly I went down to mess with the system. I squeezed the rubber hose just before the filter and felt a crunch then the engine reved up fine. It was a piece of fiberglass in the fuel tank. Doing the Baja bash at 3knts and no wind would have been horrible. It went well until the 110hp yanmar stripped the gears in the 50hp saildrive but that is another story.

Yeah, checked it. But it could have been from an earlier installation/problem etc

Yeah, there was a bit of that at in the threads that I cleaned off. People like to wind a bolt down TIGHT. A plastic thread into which a metal bolt is going can not be wound down tight. But its hard to tell how much preassure to apply and its not much at all on a thread such as these which doesnt need to be air tight anyway.

More and more stuff these days is plastic, my whole dinghy outboard is plastic except for the bill....


And stainless steel aint SS anymore, either lol.

As zeehag says, glad it didnt happen in some dire spot, and glad its gone now.

Boats are funny... You never know what trick they will try next.

Good one, Mark!

I've noticed that when our boat starts acting hinky the best results come from working on her feminine aspects. You know, buy her a bit of bling (new sails work well), or polish up her shiny bits. Do that enough and she's smiling again, motor purring, wake clean, all well in the world.

OF course, cleaning the crap out of her tanks helps, too!

Cheers,

Jim
