"Wondering if someone can help
"Wondering if someone can help with a problem that I am unable to resolve with my port KAD300 Diesel engine. The fault is when accelerating out of the water, both engines both reach 2800 rpm and the superchargers kick out as they are meant to. The port engine then drops back in revs that causes the supercharger to kick back in. The starboard engine eventualy drags the port engine over the fault. Both engines then power to 3800 rpm. However, in sloppy water I find that there is definately a power problem and sometimes cant even reach 3400rpm.
I have replaced primary and secondary filters, swaped suction fuel lines to illimate fuel tank blockages. I have even hooked up a seperate fuel tank to put to rest blockages. I have inspected for fuel leaks non apparent. Air filters clean, checked the inlet manifold which is free. After consulting with Volvo and spending $1000 I removed both computers and sent them back for a firmware upgrade that would apparently fix the problem according. Guess what, it made no difference.
I know of another boat identical to mine with the same engines that also has the same problem.
Has anyone else experianced this fault?
Can anyone help?
Thanks
Rob"
