Anybody else with this engine having issues? I went through 3 coil packs and finally had all of them changed out under warranty. Merc pretty much admitted there was a coil pack issue and that the new ones were better, no problems since. Fished Roosy on Sat morning and at about 1PM I come off plane and I hear a squealing sound, fished a little more and went home. Take the cowling off and start the engine and it sounds like one of the pulleys on top has a bad bearing? I'm not an outboard mechanic by any means, but damn this is getting frustrating. This engine is on an '07 BassCat, not a "boat issue", trying to avoid a boat bashing thread. Just curious how other guys have faired with the same engine?

Never had the coil problem.. I blew the air pump first. Then a powerhead on my 08 at 300hrs. No problems yet with the 09.

coils

Yes, Yes and Yes...

I have gone through 4 of the six. Finally have it resolved I believe. It was a common problem when they first came out. From what I understand, the Mercury tents at the tour level tournies had lines to fix this very problem.

I will cross my fingers that the other two don't go out and that the problem is fixed.

Other than that, best engine I have ever owned!!!

Sounds like you may have an air compressor issue.

I've had a Yammie and now have an Opti. Excellent performance from both.

It's a matter of the odds - any mechanical device can have problems. But I look around at the number of guys I know personally with Yammies, the number of guys I know with the Optimax, and the postings about both on reliable websites like BBC & it's pretty clear that the Optimax has higher risk of problems than the Yamaha.

Why did I get the Merc? Only one reason - the nearest Yamaha technician (at a place I don't completely trust) is in Phoenix & there's a certified Merc tech here at Roosevelt.

If I were doing it over again, would I make the same decision? Hard to say for sure, but I'd probably go with a Yamaha.

Wow! All of this info. on failing motors makes me sick and confused as someone in the market for a used boat. WTF? One minute, I'm hearing about troubles w/ Rudes, the next it is the mighty Merc Pro XS which was talked up as if it was sent from the heavens above! Isn't anyone interested in making a solid, reliable product without silly issues that cost the owner money and time? Doesn't any motor manufacturer get rid of the freaking bugs in their product before they hit the market? :confused: A "lemon" = no / poor quality control.

No they are just like car dealers, get the new product out and fix the gremlins as they show up. not the way i would do it, but they have to get the "new" stuff out to keep up

I wonder who the vendor is that is producing these bad coils for Mercury? Does anyone know? Are the parts made in the USA or outsourced to a third world country to save costs? The latter could reduce the quality of the parts if they are not designed/manufactured correctly and/or extensively tested. Frequently, sending work overseas = big bonus for the CEO of that company.

I'm not saying this is the case, it sometimes it feels like the conusmer is the beta-tester for some of the products we buy rather than the companies who make the parts testing them extensively before the product is released to the public.

That being said, Mercury is still responsible for the warranty costs and it would be nice if they had a recall to replace all the suspect coils, but I doubt that they will do that and pay for it.

Yamaha is the most dependable outboard made...if mine blew up tomorrow, it would still be the best...

having owned both the yamaha and mercury 300s, I would take the mercury any day. Get all the coils replaced under warranty and the rest is fine. Mercury tried to make one part perform three functions instead of three parts doing three functions and it just did not work out. They have fixed it on the new coils. My merc runs circles around the yamaha while using a fraction of the gas and oil the yammie used. plus when I need to change the fuel filter, i do not have to change three of them at $100 a piece like the yamaha. jmho

MOST OUBOARD MANUFACTURES SPEND A TON OF MONEY ON DEVELOPMENTAL AND R+D TESTING TRYING TO PUT OUT A GOOD PRODUCT--------THEN THEY PUT IT IN THE HANDS OF THE REAL WORLD TESTER LIKE ALL OF US. WHALA THIS IS WHERE THE BUGS COME OUT.

The sqealing is most likely the air compressor. Opties are notorius on them burning bearings

How much difference is there between repair and maintenance costs from the Merc to Yamaha? For example; how much are water pumps and fuel filters on the Yamaha? I'm considering both engines but I worry a little about finding parts for the Yamaha. I know there are plenty of parts out there for the Merc but I don't see that many for the Yamaha.

Thx,
NoviceDave
