Another one bites the dust - Suzuki Corrosion

I a honda bf90a on my flounder barge. It is a 2000 model and now has well over 5,000 hours. I depend on it to get me and my crew back each night. Not one problem with it, ever. I use it only in salt water and i've never flushed it, not even once. If it ever does stop working, which i doubt, I will have it bronzed. If you want the best outboard motor, car, generator, etc go with a honda.

I took my covers off today and with the help of some pics off the web I found I was looking in the wrong place and my motor does have the plug. It came out pretty easy. Just the end had started to corrode. I ordered the aluminum plug and will install it after Lake Powell. Looking at all of the pictures I think all of the manufacturers have had corrosion problems at one time or another. I don't get why Suzuki didn't just replace the plug when the problem started. Mine looks very minor right now but my boat spends most of its time in fresh water that must be the difference. I'm at 767 hours right now.
 
Hi Jody,

I have the 2005 Johnson 90 (same as suzuki) but I could not get the plug out. The allen just stripped. The plug was covered with the original paint which did not help.

Do you have any pictures?

I use an allen wrench and a combination wrench and put some pressure on it and snap it came right out. Threads still look good and I could feel around inside the hole didn't seen to be any corrosion in there. Plug looked like this.

I pulled 2 of the anodes and they looked clean. I didn't pull the other 2 anodes because they had gaskets and I didn't want to ruin one right before the Powell trip so I'll wait till I get back.

You might try taking a die grinder and cut a slot in the plug so you can put a piece of flat bar in it and turn it like a screw driver but the slot sould be across the whole top of the plug. I know others have welded a nut or a bolt onto the plug and turned it that way. Search google images for Suzuki corrosion problems and you'll find them.
 
Thanks Jody, Those are good suggestions and good pictures.

I am curious about the anodes shown. Where are they on your motor?

I replaced the two that sounds like to other ones you mentioned. They have two bolts on the fitting that holds them and are on the side above where the oil dip stick is. These two were very corroded on my motor.

If there are two more I may have missed them.

Thanks,
Steve
 
They were on the same side of the motor to the right of the plug and up higher towards the top of the motor. Sounds like the other 2 were where you found them.

I'm glad you located the plug Jody and were able to get it off. I removed my plug back in March 2014 and I too used an Allen wrench attached to a ratchet to get my plug off. I inspected it and it didn't seem too corroded. Sorry it's a blurry picture but I believe the inside of my plug was very similar to yours if not better.

I was hoping 2 1/2 years ago that I had stemmed the tide. However as we now know, the corrosion still occurred but below the aluminum plug I replaced. If you look at the first picture on page 1 of this thread, you will see the corrosion was on the oil plan below, not at the aluminum plug which remained intact and no apparent corrosion on the engine holder. I hope you fare better than I did and don't suffer the same fate. Fingers crossed for you.
