carlos- not sure how much help this will be but suggest you consider that turborchargers are sometimes made by a company other than the engine manufacturer, who may merely install them on the engines. you might try to i.d. the actual manufacturer of the turbocharger and talk to their people. if there is no mfg i.d. found on the turbochargers themselves, the engine mfg should be able to tell you where they can from. too be honest with you, i haven't had all that many turbochargers, especially with so little running time. the 2-3 i did have like that went out due to improper lubrication/oil bath problems due to questionable maintenance more than anything else.

We need your help regarding this case we are attending.

The case deals with a Bayliner 3388 yacht built on 1997. At the beginning it worked with two engines Cummins model 4BT 3.9 lts, series 45377536 and 45379245, both, according to specifications, were 155 HP, seawater cooling and 3.5/ 1 reduction.

In 1999 both turbos broke down after 400 hours working altogether. According to the manufacturer representative, in Peru, they broke down because the air temperature entering the engines was too high and blamed this on a deficiency of ventilation of the engine room. Due to negligence damage worsen as the cylinder heads crack etc.

From what we have read in the report the supplier that sold the yacht replaced both engines with new ones, also installing an air-cooling system for the engines. This system was tested and said to be the correct one so the air entering the engines be in the temperature specified by the engine manufacturer.

Recently, January 2001, both turbochargers failed again after 400 hours working altogether cracking apparently due to overheating.

After reviewing the literature I found that the yacht manufacturer offers engine-installing services as for 155 or 250 HP diesel engines is referred.

I would like to know if any of you have ever had a similar experience with these yachts and how the problem was sorted out so it did not happen again.
