SMX Seaview Alarm – Water In Fuel Indicator
This topic has 2 replies, has 2 voices, and was last updated by
6 months ago September 21, 2022 at 3:24 pm I received the attached Water In Fuel Indicator warning when I turned the ignition key on. Ā It remained on a few seconds then went off. Ā I then started the engine and let it run a few minutes and the warning indicator remained off. Ā I did this cycle 3 times and it was the same. Ā I checked the Racor filter and saw no water through the glass. Ā I replaced the Racor as well as the engine fuel filter. Ā I let the engine idle for about 15 minutes. Ā Shu…

2 RepliesOctober 3, 2023 at 4:55 pm Sirs, I recently got this same alarm about two months ago. Ā I replaced both the racor and engine fuel filters and alarm stopped. Ā Have run the boat several times since (at least 15 times, at least 2-4 hours each session). Ā Today the alarm popped up again. Ā Again, my racor shows no water in the bowl and the engine is running fine. Ā Is there something I can check before changing filters again? Per Tonyās info requests back on 9/27/22: Had the boat…Last Post by:

Seawater Pump Belt – Bolt Torque ?
This topic has 4 replies, has 3 voices, and was last updated by
1 year ago August 10, 2022 at 2:11 pm I have a 2008 QSB 5.9 425hp. Ā This morning the seawater pump belt shredded. I found the tension pulley bolt lying in the bilge. Ā Iām assuming the bolt came out, pulley wheel wobbled and belt shredded.Ā Is there a specified torque for this bolt or just get it good and tight? Thank You Gentlemen, Steve

4 RepliesAugust 13, 2022 at 9:58 am The Idler Pulley bearing is obsolete per Cummins so I just bought a new pulley from Seaboard. Ā It appears to be an easy swap but before I start something I didnāt bring tools for, is this as easy as it looks or will I need a puller to remove the old puller? Ā Thank YouLast Post by:

Error 2265 Prine Pump – High Error
This topic has 6 replies, has 4 voices, and was last updated by
4 years ago January 4, 2019 at 4:44 pm Sirs, I received this error after starting up our qsb 5.9. I shut down the engine then re started with no error. The same sequence occurred the next day. The Diesel View manual says 2265 is high signal voltage at the electric supply/lift pump circuit. So what does this mean and how do I fix it? Thank You, Steve

TRANSMISSION FLUID WEEP
This topic has 8 replies, has 2 voices, and was last updated by
4 years ago March 6, 2020 at 2:56 pm Sirs, I have a QSB 5.9 to ZF 85A with an ATF weep. It looks to becoming from a join under the port mounting bracket. It runs down the seam to the bottom of the transmission. Not yet enough to require adding fluid but I want to address it asap. All bolts are as tight as I can get them with a standard wrench. Is this a gasket replacement job or much more involved? Can this be resolved in the slip? Thank You

Tensioner Pulley Noise
This topic has 5 replies, has 4 voices, and was last updated by
4 years ago February 24, 2020 at 3:06 pm We have a QSB 5.9 425hp. I was doing a fresh water flush when I heard a wine coming from the tensioner pulley. The belt tension looked fine so I sprayed some T-9 into the pulley and the noise went away. Is this a legit solution or should I be ordering a new belt tensioner because mine is on the way out? Thank You, Steve I attempted to upload a photo of the tensioner pulley but can’t seem to get it through.

Temp Creep
This topic has 9 replies, has 4 voices, and was last updated by
5 years ago March 18, 2019 at 5:28 pm Sirs, We’ve had our boat for two years now. Single Cummins QSB 5.9 425 hp. The heat exchanger, and coolers were all serviced immediately after purchase. In fact the aftercooler was replaced due to pitting. We fresh water flush fairly regularly and just completed this year’s annual service (but haven’t done the aftercooler yet). In the two years we’ve owned her, the temp has never broke 176 at cruise (2400 rpm) nor 179-1…

9 RepliesMarch 22, 2019 at 10:50 am Sirs, I replaced the thermostat. After a number of test runs she never broke 176 bringing her to 2400rpm cruise and settled at 174-176. WOT never broke 178 and settled at 177 (staying at 2940-2950rpm). whew….itās about time I get an easy fix. Iāll keep a watchful eye on my seawater pump and the aftercooler is scheduled for removal/service in early April. Thank You for all your input. Much Appreciated.Last Post by:

Coolant Loss
This topic has 11 replies, has 5 voices, and was last updated by
6 years ago September 27, 2017 at 1:08 pm Gentlemen, We have a single 2008 Cummins QSB 5.9 425hp on a Back Cove 33. It was serviced in May 2017 (740 hours) which included coolant replacement and heat exchanger removal/servicing. After about 40 hours, I noticed the coolant level had gone down around 2 inches in the reservoir. I figured it was burping after the coolant/heat exchanger replacement so I added coolant to the reservoir. I marked it to monitor and it is continuing to go do…

11 RepliesApril 30, 2018 at 10:02 am You’re right re: the heat exchanger/coolant…same with our QSB. My typing was in gear but my mind was in neutral…sorry Anyhow If I remember right, I’d guess it took us about 5 trips out about 2-3 hours each time before it settled. I just added to the expansion tank after the engine cooled. It was always full at the engine cap. Haven’t touched it since. SteveLast Post by:

Lower Aftercooler Zinc All Gone
This topic has 5 replies, has 3 voices, and was last updated by
6 years ago March 23, 2018 at 9:37 pm Did an annual service today which included replacing the three zincs in our qsb 5.9 425hp. The top zinc of the aftercooler and the heat exchanger zinc looked fine. Attached is a picture of the zinc on the bottom of the aftercoler. This is after 11 months. About 140 hours worth. What is going on here? Thanks Steve

Exhaust Riser Doomed to Fail
This topic has 11 replies, has 6 voices, and was last updated by
6 years ago October 30, 2017 at 6:14 pm Sirs, From reading prior posts and articles, it looks like we have an exhaust riser that is “doomed to fail.” It’s the factory set up for our 2008 Back Cove 33 with QSB5.9 425hp. We have about 850 hours on it. What are my options here? Can the elbow be rotated, is this a custom fab job or is there another possible solution? (Sorry about the last photo, I couldn’t figure how to rotate it) Thank You, Steve
