Onan Generator fuel leak
This topic has 1 reply, has 2 voices, and was last updated by
1 year ago March 13, 2023 at 11:30 am I have an Onan 17MDKBP generator that has developed a small fuel leak. I’m trying to determine what needs to be replaced or repaired. I have traced it to the valve in the photo – you can see a ring of diesel around the shaft. The valve operates – when you turn it, fuel comes out of the opening – but when it’s closed, fuel slowly drips out.Ā I’ve looked through the diagrams and parts manual, but do not see this…

QSB 5.9 with Zeus pods – where is gear lube cooler?

August 9, 2021 at 7:24 am Good morning all, My 2012 Sea Ray is powered by twin QSB5.9 480 HP mated with Zeus 3000 pods. Just recently replaced transmission oil and steering fluid coolers due to their age, two per pod. The QSB maintenance manual calls for the gear lube cooler flush, but I can’t seem to locate one. Is it possible that the pods don’t have one? Many thanks, Yury

Zeus Pod hydraulic pump surface corrosion
This topic has 3 replies, has 3 voices, and was last updated by
3 years ago January 17, 2021 at 12:36 pm I have a 2017 boat I purchased last year with twin Zeus pods. I’m in fresh water, and the previous owner was also fresh water. The pods work great, but on both pods the Parker hydraulic pumps have some pretty nasty looking surface corrosion (see pictures). The rest of the pods surface seem fine. Wondering what could be going on here. Thanks, Scott

6 RepliesNovember 3, 2020 at 3:50 pm I presume the QSB has similar diagnostic capabilities as QSC and if so I would get a Cummins Engineer down to the boat and have him plug in his laptop and bring up the Duty Cycle Monitor. This will show exactly where your engine is running with respect to torque % over the full RPM range. This information in addition to the theoretical (and corrected) fuel curve will help in your decision on whether to keep adjusting propeller pitch.Last Post by:

After restarting the boat 4-5 times, the port side caught up/corrected itself and now matches the starboard and they are both showing 237 hours. Any idea what could cause this? Thanks!!…
