Hello, new to the forum , glad to be here ,have a posible problem on a 2006 Honda outboard engine (2006 BF200A6 LA ) had this engine for 4- 5 months and everything is running fine ,have been out 3-4 times 30 miles out everytime , last week coming back from fishing while flushing engine at home heard a knocking sound out of the mid section not at the engine but just below the engine , next day took the covers out and started the motor , it was a very low sound at first then as time went on say 4-5 minutes it started to be a bit louder . took a metal rod and went on on different parts listening to as where it was louder and it is at the mid section right below the engine , any ideas as what it could be ? what 's in that section just below the engine ? ,is there a transmission in this units ? thanks in advance any thoughts is greately appreciated this is a video of the engine running
 
It is the drive shaft support bushing. Bellow is a picture of where it would go.

thanks for your prompt responce docksidemarines , I took the lower unit out last week and inspected the inside and I saw a bushing kind of a rubber b ushing being hold up by a snap ring is that the one you are talking about ? looks to me in your pic is farther to the back . almost on the back part of the lower unit , is it something easy to fix or is it something a pro have to do ? thanks in advance
 
It is simple to fix. You need a good set of snap ring pliers. It is in the front of the exhaust housing. Pull the ring and the washer and you can pry it out. The bronze bushing is in-cased in rubber. A little PB blaster will help.
 
Exellent , will order tonight and i'll report back later on the week , now just for learning , can you please tell us how can that support bushing without turning on the spot at all make this noise ? it also increases as the engine revs up shaft not turning and the noise increases .please tell us . thanks
 
Chris - that's some ugly damage in those pictures! Question for you - are you seeing more problems with the 30" shaft setups, or doesn't the shaft length seem to make a difference?

Based on other posts on this forum, it seems like the only permanent fix for this issue is to install a newer cover that has larger water posts to lubricate the bushing better, as Jamie described in some posts a while ago. Do you agree, or are there other methods for a permanent fix?

Bottom line, in you opinion why does this happen with some of the 200/225 engines, and apparently not other?

Guys,

FWIW, I never heard that type of sound when mine let go, but looking back, every once in a while I would hear a random "screech", which sounded like a belt slipping. Must have been that rubber bushing binding up.

Chris,

I have about 100 hours on the new Mid-Section. do you think the new design fixed the problem? We will be dropping the lower unit later this Spring, and I'll post pics if things aren't looking right

I don't think shaft length has much to do with this. I think it has to do more with the quality of the casting. As for the new design helping, only time will tell.
 
Chris - thanks. At 1500 hours on my 2007 225, I try to stay alert to potential issues. My goal is to get at least 4000 hours out of this engine if the Good Lord allows me to stay around that long.
 
Well ,sorry it took me some time to get it installed , changed the bushing , there is no dought it needed to be changed ,however the noise still there ,has not changed at all , checked it carefully and sounds right at the bushing location not higher or lower than the bushing area . question : could it have something to do with the impeller or water pump assembly all together ? thanks in advance

think it has to be somewhere along the water pump because it makes the noise right at above the water pump , more to the low bushing area ,now the noise as you can see in the video is a low noise that increses and decreses with rps ,can be echoing in that general area and be actualy in the lower unit , it was good that i changed the bushing it was bad regardless , also let me mention that i bought this boat few months back, being out on it at least 10 times 30 or 40 miles out every time , no problem . did changed the lower unit oil and it was clear and good , no remanents or shavings or nothing pure good oil . the water pee however i think when in iddle has decresed a bit ,not as powerfull as before . no overheating at all engine seems fine with water temperature .
