Lost rpm
Had a problem with port engine not keeping up with starboard and same engine unable to go over 1800 rpm. These are 250 B cummins diesels. Problem turned out to be fuel shut off. Brackett holding shut off had nearly fallen off engine, Two of three bolts missing and third holding by a thread. Also, fuel pump backet on good engine had cracked and one of the injectors was leaking. Please note that Cummins will warrantee fuel injectors on cc28. Has anyone else had this problem?

i had the same problem with the bracket on my starboard engine , it cracked and bolts broke off , it cracked on the weld . i was bringing my boat back from cape hatteras to virginia in 3-4 ' seas and everytime i took a hard swell the engine would shut down , the plunger on the stop seloniod would shut down . the bracket is not expensive . i have learned with these engines that you have to check things constantly due to the vibration . everyone keeps telling me they will run for ever , but my experience is they are expensive to maintain because little repairs like this turn into big repairs . i keep thinking i push the boat to hard but it seems others have the same problems.28 Classic - Brown Eyed Girls -
Have you also had to repalce injectors? Factory is sending me lubricating fuel filters at no charge to help prevent this problem from happening again. In four years, I've had little out of pocket expense for engine repairs. PaulComment

can you explain more about the lubricating fuel filters?? we have replaced our injectors 8 times now. I need to know what to ask them.
also, most of the 4b's had problems with the brackets breaking. I think there was an updated bracket that was a little beefier to handle the vibrationComment

AS soon as I get the filter, I'll post the part number. Paul
PS did you replace 8 injectors at once or all 8 eight times?Comment

8 sets of injectors...all under warranty so no real complaints...just a hassle
would like to try the fuel filter as long as it is a fleetguard part...Comment

Some people are also using Howe's "Meaner Power Cleaner" additive. Apparently it increases fuel lubricity and helps ease some of the injector related issues in the 4Bs.Comment
