Hi All, Thanks to this forum we have been learning all about maintenance of our boat, what to look for and to expect and how to handle maintenance. Ours was a well maintained boat but like all boats, maintenance is ongoing due to preventative maintenance playing a huge part in overall maintenance.

We wanted to let anyone new to maintenance know that at 250 hours we had to change out our 30 HP Yanmar exhaust elbow due to excessive carbon buildup. It's not good to have such buildup because it could allow water to get back into the engine which can throw a rod- Not something you want happening in a watery wilderness, especially if a small craft advisory hits. Fortunately I have a husband who likes to stay on top of things mechanically and so he checked this out after advice given on this and other sites- Thank you!
 
Hi Shangie,
is the carbon buildup not cleanable on this elbow? what does a new one cost?

Cost of Exhaust Elbow, joint for elbow (I damaged during removal) gasket and shipping was about $250 , had the old one cleaned at radiator shop and kept for spare.
Hope this is the information you were looking for. Bob
 
Just as an FYI I just bought the SS setup from HDI Marine for $308 + shipping (don'T have exact cost in front of me).
Had the CI one crack on me on my R21 and did not want to repeat that on my R21ec, piece of cake to change. The kit came with all 3 parts and gasket. Smart idea to have old parts cleaned for spare.
 
Oh, thanks guy,s, looks like a spare is needed for long rang travel.
Thanks
