Thanks for the information. The 4000 rpm was without prop engaged. We have
yet to test out boat speed v. rpm. Volvo mixing elbow cost here in Maryland was a bit over $600. _____ From: amelyachtowners@yahoogroups.com [mailto:amelyachtowners@yahoogroups.com] On Behalf Of asm283 Sent: Friday, March 24, 2006 12:56 AM To: amelyachtowners@yahoogroups.com Subject: [Amel Yacht Owners] Re: Volvo TMD22 heat exchanger Hi Mike As I write this my cooling system is apart for serice. Same sort of issues, blocked tubes with growth and calcium deposits. The miximg elbow was corroded and needs replacement. I did find what looked like weeds. I cant believe that these got trough the strainer then made it past the impeller and then into the tubes. It must be some kind of growth. I have spent quite a bit of time in the tropics and strange things grow out here. This is the first time I have done this on my 6 year old boat. As far as the carbon built up in the turbo. This is a trait of this engine. It seems that everyone has this problem. Just put it on your maintenane list. I have had it cleaned and serviced twice in the past year. I have done a lot of low RPM motoring in the past year (600 hours) wich will cause the carbon built up. You will find that you will run at low RPMs in order to get better fuel economy. Important for long passages. Also, check your muffler for corrosion. When you say that you got the engine up to 4,000 rpm is with the prop engaged. What was your speed. Good luck with your SM. Sevice her and she will treat you right. I crossed from Guadaloupe to New Zealand this year and not a thing went wrong with the boat. People with much more expensive and newer boats had many more problems that I did. There is a maintenance list written by Mr. Selo of Amel floating around this site. Follow his recomendations and the boat will work well. Maybe someone who is closer to you can send it to you.

Perhaps it was the restricted flow that resulted in extra highpushing back from the injection elbow into the turbo which wassignificantly carboned up. After a thorough cleaning of both the heat exchangerlook- see would be appropriate at least every 500 hours. _____ YAHOO!
