6BTA to Digital Gauges

2 years ago March 17, 2022 at 10:27 am A year and a half ago I posted about having some issues with my instrumentation (WIF alarm, hourmeters not progressing) and mentioned I was planning to move to a Chetco SeaGauge but I purchased the replacement panel from SBMAR and got the WIF turned off. I just got around to installing it and I have it working with my N2K network with Raymarine Axioms and i70s (see attached pic). I have the stock harness with this helpful wiring diagram from thi…

Wiring for 6BTA tach hour meters?
This topic has 5 replies, has 4 voices, and was last updated by
3 years ago June 9, 2020 at 11:09 am I have the new board to fix the WIF alarm (https://www.sbmar.com/community/topic/yet-another-wif-sensor-problem/) and before replacing it I wanted a quick check – does this board have anything to do with the hour meter on the stock Cummins tach? I’ve had my boat for 2 years, neither hour meter has changed since the sea trial, and I was thinking it was a disconnected wire running from the key to the tach…but the tach has a bunch…

5 RepliesJune 12, 2020 at 6:56 pm Searching on a related topic I ended up with the diagram that shows the wiring connection to the tach: https://www.sbmar.com/wp-content/uploads/2015/11/B-C-Panel-wiring.pdf That other thread also mentioned that it’s not just the key power, but there’s something in the tach having an RPM reading that turns on the hour meter. Anyway, I ordered the Chetco interface today so I won’t be bothering to fix this.Last Post by:

Yet another WIF Sensor Problem
This topic has 7 replies, has 4 voices, and was last updated by
3 years ago May 18, 2020 at 6:53 pm I’m in over my head here – I’ve tried the forum resources and I’ve failed, what am I missing? My port WIF sensor has deteriorated in the 2 years I’ve owned by 1999 vessel (starboard works fine). It periodically started going off last season – a few button pushes and it was quiet. This season…I’ve only been out for a couple of quick trips but it doesn’t stop. Engine is Cummins 45728072, 5.9 6B…

7 RepliesMay 19, 2020 at 11:56 am Thank you for the pointer Corey. I carefully compared your board with mine and can see all of the connections and mounting points match up. Would you suggest swapping out both boards? I’m not sure how to evaluate those changed alarm points. Are there any other improvements?Last Post by:

Longevity Tradeoff 6BTA
This topic has 2 replies, has 2 voices, and was last updated by
5 years ago September 16, 2018 at 7:53 am I didn’t get a response to this question in my other thread, so starting a new one: I have a recently acquired Little Harbor WhisperJet 36 with twin 315/330 6BTAs driving Hamilton 273s. 1999 boat, about 600 hours, service history relatively unknown but I just had a complete service by Hatton Marine in Seattle. Impellers were in good shape (though a bitch to change, will do Tony’s kits next time) and there was a slight swelling in the…

2 RepliesSeptember 17, 2018 at 6:52 am Thank you @Tony for the detailed response! It’s going to take me a while to study those charts, but I’d like to explore your “during a 8 hours day”. What if that “day” is just Saturday and Sunday 10 times a year? I just ran across a mention of M1 through M5 (continuous duty to weekend and day trips) and believe these are M3 engines. And your fuel burn…I said that the consumption is relatively flat for a…Last Post by:

Help Identify these 5.9 6BTAs
This topic has 8 replies, has 4 voices, and was last updated by
5 years ago July 10, 2018 at 6:58 am Greetings – first post here, any input appreciated. I am closing on a Little Harbor WhisperJet 36 with two B5.9-M330: 45692569 (19 May 1998), 45728072 (21 Jul 1998) each driving a Hamilton Waterjet 273. Both have about 580 hours total, the boat was lift kept until the owner became ill, maintenance history is unknown other than the oil & oil filters were changed in April (about 2 engines hour ago, no details on what oil was used). Durin…

8 RepliesSeptember 1, 2018 at 7:21 am @billd – thank you for your reply. I’ve read Tony’s article on “Continuous Duty” https://www.sbmar.com/articles/continuous-duty-a-different-perspective/ and – if I understand correctly – would yield 55.9 hp/liter for my engines, and if I do get the 1nmpg expected at WOT would mean about 2.54 gal/liter of fuel (per engine). So…running at WOT I might get that 2500 hours, subtracting my 500 hours and …Last Post by:
