Suzuki owners - question

Localboy. I also noticed that the external anodes carrode at a much slower rate than the internals. My internals were 50% gone at 360 hrs. The externals simply need a yearly brushing to remove the fuzz but I was amazed to see the condition of the internals. My official Suzuki motor manual says absolutely nothing about the existence of the internals. Good thing I have the Brats to raise the question or I would have never had a clue! Thank you kids!!
 
Now to the question of why these anodes are needed. Obviously the motors are made of low grade non marine aluminum-try to find any anodes or corrosion problems on vintage USA outboards, and they never got flushed after saltwater use, either. If I follow the advice from Suzuki, I should keep my motor in climate controlled conditions and never use it.

(It was my Suzuki that exploded, Suzuki is very difficult to deal with, it took more effort than I can even explain to settle for a 1/2 price motor and mine was under warranty. Anyhow the new 90A has 500 trouble free super babied hrs. on it)
 
The anodes I have replaced have disintegrated, not totally, but noticeably. We pretty much only used the boat in Puget Sound etc.

What I could observe inside was just remnants of the aluminum, but we flush our engine religiously. In fact, when I pull it into the driveway after each & every trip, I use "Salt-A-Way" to flush the engine.
 
Two new 2016 Suzuki DF50 engines on Sealife, new white color. Looks great.
When the shop installed them, they took it upon themselves to raise them two notches higher. My original engines were installed at the old C-Dory factory, and I'm wondering if they had them lower from experience? My WOT is right where it should be, but it seems to ride with a higher bow, and requires more trim. Anyone have experience with this?
 
Mike: your post begs the question of how you arrived at 2 new Suzuki's? Did your previous dealer and/or Suzuki make an accommodation for the previously mentioned issue? Anti-cavitation plate flush with hull bottom at transom is a typical motor height target unless you have an OB bracket. Good luck with the new twin motors! Mike
 
Here's the story:
Overheat light would come on. First dealer checked pump and said it not that so it has to be a water restriction in the power head. Tore down the power head and still had the problem. Dealer could not figure out the problem, suggested running without thermostat to increase water flow. I didn't like that solution so took the boat to another dealer who I knew was the best in the area. He questioned me as to what had been done so far and determined the first dealer had not checked the mid unit, only the power head. He was fairly certain that's where the problem was so I authorized another tear down. In the process, he discovered internal anodes that were completely disintegrated and plugged water passages at the anodes. Cleaned them out and restored full flow, however shortly after, the engine quit with water in the oil, indicating a perforation due to corosion. End of that engine.

Turns out in 2005 (year of my engines) Suzuki added internal anodes, adding a small one line addendum to the service manual, and requiring all dealers to attend a seminar where the changes were discussed. However, no mention of internal anodes, or maintenance of them was included in the owner's manual, Suzuki relying on its dealers to relay that information. In the 11 years in which the same dealer serviced my engines, they never checked the anodes, so for years I ran without this corosion protection. Due to their negligence, I am taking them to court to recover damages.

P.S. New engines Owners Manual lists internal anodes and a frequent inspection schedule.
 
As I said in my last post, I was taking the dealer to court. I filed in small claims court for all my repair costs, and the value of both damaged engines. His insurance company made one ridiculous offer to settle, which I refused, and weeks later settled with me for what I wanted. Lesson.....when you know you are right, go for it.

The upshot is they were clearly negligent in not checking the internal anodes, not even when they tore down the power head. I had a witness in the second dealer who did a forensic tear down, and photographed the corroded anodes.

I have two new (white) Suzuki engines, 6 year warranties, $200 rebates, and a super purchase price. I'm a happy camper.
 
Down the road 20 hour maintenance. New engines run great. Fuel economy is even better than previous engines. Unhappy with engines raised a notch. Bow high, hard to see over it, and slight vibration. Had them lower to previous engine notch, and big difference. Rides just like previous engines....I can see better, fuel economy still great, vibration gone. Super quiet too.

Received my Suzuki rebate checks of $200 per engine, and six year warranty. Still own the two old engines, one bad, one good. Am posting the good engine on E-Bay, but if a Brat needs a 50hp, I'll make him a good deal.
 
End of a long story. Sold the good, old engine for $1800. Am getting 1.9 gph combined on the new engines, compared to about 2.3gph on the old one. Two new AGM batteries....like a new boat. Sure happy with the canvas I designed too. Because it covers all the dark blue hull color, the finish still looks new. Ready for another year of CGAUX patrol work.

Awesome! So maybe going forward Friday the 13th will be a lucky day for you. Lol
 
If one searches "Suzuki outboard motor parts" on line, there are illustrated parts breakdowns of all of their engines. I found my 90hp, 6hp, and 2.5hp and the anodes in each engine. Sorry I lost the address. I ordered spares for all engines.
 
Thanks to this group I checked the internal anodes on my 2007 150hp 425 hours and there was some left but not much to each of the 6 internal anodes. I could find no mention in the owners manual. I downloaded a shop manual online and it had a very basic but no details mention of internal anodes. Brownspoint was the only place I could find a detailed diagram.

I asked the service manager at, in my opinion, an expensive marina in Destin that services the boat for us as well as for a very contentious previous owner why they didn't know about the internal anodes. I was told that they did know about them but I would need to ask them to replace them. It's not something they would bring up. I'm embarrassed to tell you guys what they charge for a 100 hour service. For what they charge it should come with a fancy dinner OR AT A MINIMUM the required service. I started looking for another Marina over Christmas.

I am really glad I saw this on the website. Thanks!
