Hopefully this will help someone in the future. When I purchased my boat, a 2009 Ranger 25, 3 years ago we never expected the problems we were going to have with the Mercruiser / Cummins marriage and subsequent divorce. Last fall after watching this forum I read several comments about going 20 kts with their boats. If I tried to go faster then 12 kts the engine would overheat. I took it to my mechanic in Northern Michigan and he cleaned both upper and lower coolers, (so he said). He decided we should check out the turbocharger which he sent to a company in Grand Rapids, MI. They said they couldn't do anything with it. I then did some research on line and found Comp Turbo in CA who said, after I sent them some pictures, that they could rebuild it. By the time I got it back it was to late in the season to install it. My wife and I are on our 3rd year doing the loop. During a warm spell in January we headed south with the boat on our trailer and found a marina in Wilmington NC who installed the turbocharger. Because of heavy fog we couldn't do an adequate sea trial but the mechanic was confident everything was ok. We got 30 miles before the turbocharger failed. We wound up in Holden Beach Marina, NC where we have been for 11 weeks. Comp Turbo has a 12 month warranty on their repairs. I sent the turbo back to them and they claimed they couldn't fix it. So much for the warranty. I asked if they could get me a new one since I couldn't find anything on line. They found one after about a week in Japan they claimed, for $1200.00. They had it shipped to them so they could do a dyno test on it prior to sending it to me. After at least 15 phone calls all made by me since they didn't return one of them we found the turbo in New York shipped from Germany not Japan. After another week they received it in CA and then after another week it was sent to me. I then had to order 5 gaskets and you guessed it, one was on back order so we waited another week. When they sent me the new turbo they didn't strip all the parts off of it. when I called to find out about the oil tube that was on the turbo they said they would check on it and get back to me. This never happened nor have they returned any follow up phone calls. I might mention the marina I'm in is a mercruiser dealer but they only work on outboards. They are still very helpful with parts. They also recommended a mechanic who could put the new one on. While he was installing the turbo he removed the after cooler and found it full of sludge. He said there was no way my Michigan marina had removed that part and cleaned it since it couldn't possibly get that filthy in 30 miles. I tried to order a new oil drain pipe from the marina I'm in but they said it would be a least 2 weeks because Mercruiser didn't have them in inventory. I did find one on line from a company in New York. The tracking shows the item was received by the Roc Way New York post office and they told me they had received it and sent it on but they don't have any additional info. I am now in week two waiting for this part. I'm only writing this so anyone with the same engine I have and the same problem find somebody who can help you with the whole process. I cannot, with my vocabulary, explain the frustration we have gone through.
