    Anyone have a good exhaust manifold for sale?

    Would prefer a fresh water one.

    Thanks!

    Even the new ones are not good. Honda needs to improve their casting process.

    Too bad we can't find someone that can repair these, I'm going to take my old manifold apart and see if I can figure out where it's leaking. Best thing would be to get a company to make a casting for one and stamp out about 100 of these but make it slightly thicker. Might be worth while to look at the H20 Extreme stainless steel exhaust.

    Dale [from AU] and I talked quite a bit about the manifold problem [while he was visiting the US recently] and he had investigated what was causing the failures. He found the thin passages were very porous and could hold salt in the pits. The next one I have go bad, I hope to send my in new 1080P endoscope/borescope into it to see the leakage.

    I am not sure that H20 Extreme is still in business. I was also told their SS headers were not for rec riding since they would overheat.

    I do not see how Honda can continue to sell a very expensive part that is clearly defective. Maybe that is why they are on national backorder, to prevent someone from sending the lawyers to visit them.

    Honda is definitely not the company they used to be, from the car's VCM engine failures to the weak valve springs on the Aquatrax.

    Re: Anyone have a good exhaust manifold for sale?

    Can't wait to get mine running and sell it. Pretty disgusted about spending $800 on a part that rotted out, that's clearly in a spot that should be designed not to.

    If I'm thinking correctly, the manifold cracks/rots and lets exhaust into the water jacket. Also cracks/rots and lets water escape from the water jacket into the hull. So it's actually 2 problems, the exhaust into the water jacket, and then the water jacket leaking. I'm thinking of essentially a typical exhaust header completely surrounded by a water jacket to control heat.

    If this is correct, I wonder how many Honda's have the initial crack with water getting into the exhaust without the external leak to the hull. This would explain many skis having less than optimal performance as there is also water going through the turbo exhaust wheel/housing.

    I can guarantee mine will never see water again with me being the owner. I'm so sour on Honda now I can't wait to sell it. I know there is no perfect ski, but I'm not going to deal with national backorders again.

    Rant off.
