Does anyone know what model year Honda first installed the modified exhaust manifolds to prevent backwash from coming into the upper exhaust manifolds and pistons? Is there a retro fit for earlier models?

Rick - thanks. Yesterday I managed to get my hands on a complete printed copy of Service Bulletin #56. I'll scan it and send to anyone who wants a copy. I found their analysis of how water could be drawn into the combustion chamber very interesting - it's on page 7 of the Bulletin. I also find it more than a bit disconcerting that it took Honda about five years to adequately address the problem.

"WDN, ive tried several times to email you for the Service Bulletin #56, but it seems the address supplied dosnt work. Do you have an alternative addy i could try? I would very much like a copy of the TSB, as the Honda Tech. hotline here is unaware of it.
Cheers. Jon."

"What kind of exhaust problem? If you want some help, provide more detail."

water backflows into exhaust end up replacing o2 sensor yearly. I know its a common problem in Honda because exhaust ports have nothing to keep water from back flowing into them

"Aristakat,

That problem can actually destroy your engine if not taken care of. See earlier message from Ricksterpr, above. If your SN falls within those ranges, then Honda needs to modify your exhaust system. That is covered in Honda Service Bulletin # 56. Send an e-mail to me at wdneal@sdrnet.com ("") and I will e-mail you back the service bulletin in .pdf format."

"This is what the exhaust looked like before the Service Bulleting #56. Pictures taken by my tech so thanks man if you're reading this...http://www.marineengine.com/discus/messages/12482/287241.jpgExhaust

Ricksterpr - WOW - that's nasty! Did Honda cover the repairs under warranty?

They gave me a little of the old round about but yes they did agree to do so under warranty. Engine hours are 248. The say two more hours and I would have to foot the bill. However last year the engine had the sensor and spark replaced and they failed to apply BS #56 so that was a point on my favor...

"Roger that. It's their design flaw, so they should cover it, regardless of time or hours. In the auto industry, a design flaw like that would have spawned a class action lawsuit in a New York second. Of course, only the lawyers benefit from those. What bugs the heck out of me is that it took them over five years to admit they had a serious problem with the exhaust port design. Seems like they generally make good on fixing it, which is the good news. I just wonder what other design problems are lurking under the cowling of these V-6's."

anyone got a contact number to get ahold of a district manager for this problem ? I live in south Florida and seems like everytime I needed warranty issues it took forever to get resolved or to for them to get ahold of a rep for area.

Agree - besides the exhaust manifolds, both are serious design flaws in my opinion. One particular issue that ticked me off to no end is that until recently they did not provide and NMEA 2000 electronic outputs in order to monitor engine performance in real time. Instead, you had to purchase those funky, hard to read, digital gauges for an outlandish price - the two gauges were over $1600.It seems that Honda's small engine tradition and experience allowed them to make excellent smaller outboards. But when they decided to "marineize" their large auto engines, they made some serious design mistakes, like those already mentioned. Underneath it all, the 200's and 225's are Honda J35 (A3 or A4) engines. Those are real work horses. But all the modifications needed to make it into an outboard seemed to have stumped Honda's normally outstanding design folks.

If it was a warranty repair, Honda will have a record. I think Hondadude has access to their Intranet. If he doesn't chime in, call customer service in Atlanta, and ask them. Have your engine serial number ready.
