"I picked up the risers yesterday. Thank you. They look absolutely fantastic and I’m sure my client will be thrilled. Thanks for supplying the heat resistant pads. That’s saved me from having them made up. I have another client with a turbo’d Hino that will require a replacement riser. As soon as I get his green light I’ll give you a call."

"I have just installed Stainless, which I got from Greenwater Exhaust. They were ceramic coated on the inside. I don’t think I will ever have to change these again. I have only just put them on and haven’t had a chance to use the boat yet, but I must have lost about 100 pounds in weight from my engines. These were less than half the price of the standard riser and that included freight to Sydney Australia."

"I replaced my risers with the stainless steel ones from Green Water Heat Exchangers about 2 1/2 years ago and I am quite pleased with them. One mechanic who worked on my engines before I had them replaced recommended the cast iron risers given the problems he has seen in the past with some of the SS risers. However, after installing these he commented that if he were to design his own it would be like these, so he was pretty impressed. I also felt they were very responsive when I ordered them plus they were reasonably priced."

"I installed two in my 3416 220 Hinos and used them for one season, with great success, cool temps and great performance. I operate out of Seward Alaska and am pleased with the ceramic coated SS risers."

"Greenwater Exhaust has completed my new system which is now installed and operational. I am posting this review, not because there are any other Ocean Alexander’s with Detroit Diesels here, but for those facing upcoming (and inevitable) exhaust decisions on their Cummins and/or Hinos so you can see what one vendor, active here on BOC, can supply in a very competitive market. While I am sure that other companies manufacture excellent products, I made the decision to use Greenwater primarily based on his aggressive package pricing."

Stuart, LaConner, WA

 

"I did a BOC search on “risers”, and up popped a number of threads on the subject with a lot of interest and activity. And a name new to me was Dave Dooling from Greenwater Exhaust. In a series of e-mails and phone calls, Dave got my attention, sent me pictures that conformed to the design philosophy Tony Athens had introduced me to, and made me a deal that was attractive and complete. His proposal beat out three other companies  for replacement of the cans, with a design that I believe frees me from ever worrying again about water incursion into the turbos or engines."
