    • 6BTA 330hp fuel cooler removal

      This topic has 1 reply, has 2 voices, and was last updated bywlsnow100 3 years ago

      November 1, 2020 at 9:07 pm Hi all Probably a stupid question but as i am looking into removing my fuel coolers mainly for easier access to the raw water pumps (as i remove them to change impellers) my question is with the seaboard kit comes the required fittings they look like standard barb style fittings do these need to be machine crimped or will hose clamp suffice as I believe this would be low pressure being the fuel return line ? thanks

      November 3, 2020 at 2:15 am Hi Wayne, I am planning on using a clamp and standard supply hose to make up the lines. If it works great. I do not see the need to use crimps..

    • Fuel Cooler Removal Kit

      This topic has 2 replies, has 2 voices, and was last updated bywlsnow100 3 years ago

      November 2, 2020 at 6:49 pm I have a couple of 6BTA’s (370) hp. I bought the fuel cooler removal kits but there were no instructions. How do I reconnect the fuel lines to the barbs. The video does not show what to do?? There were no instruction included.

      November 3, 2020 at 1:46 am Hi Wayne, After posting I listened closely to the video. The narrator clearly states “the return and the supply line”. The supply line is 1/2″ and the return is 3/8″. The recipient of the kit clearly needs to make up the supply and the return lines from the tank or filter whichever the case to the inlet of the supply and the return lines as necessary. I will go but some line today and make them up with clamps as necessar…

    • My fresh water flush

      This topic has 17 replies, has 9 voices, and was last updated bywayne 3 years ago

      May 15, 2017 at 3:12 pm Just installed 2 new aftercoolers and at the same time took the opportunity to install fresh water flushing. I do NOT have a water lift muffler and I have a good exhaust design which allowed me to design and install an engine OFF flush system. I had a stainless bung welded into the stainless water pipe between the sea water pump and gear/fuel cooler.Ā  This is the initial install and I will plumb to a manifold so I hook the hose up once and can s…

    • Fuel filter choice 1 2

      This topic has 29 replies, has 5 voices, and was last updated byStephen Oliver 3 years ago

      May 14, 2020 at 8:46 am Following on from my fuel line questions I have purchased locally the only fuel filter heads I can find, the have a 1″ -14 thread bosses on them. I’m proposing to use a FS1218 primary and an FS1000 secondary. As they share the same thread the same heads can be used. Is this an acceptable combo for a 6bta 330.i have clean tanks, do about 70 ish hours a year so assume my filter change intervals may be quite long? Current setup is a si…

      June 16, 2020 at 6:52 pm Well I spent the day yesterday ripping out the piping, hoses etc.. it was a close call whether I carried on pulling them out or drilled a hole in the bottom of the hull! It turned out that they had used copper flare fittings and no adaptors to the tanks – and then epoxied the flare fittings to the valves… at the bottom of the tank which is aluminium.. lots of heat, cursing and skinned knuckles.. I finally got all 6 out! As for the p…

    • 160 deg thermostat 1 2

      This topic has 22 replies, has 6 voices, and was last updated byJohn 3 years ago

      February 2, 2020 at 9:35 am Hi guys simple question I hope… I have read Tony’s tips searched the forum etc but hoping for a straight forward answer Is there any reason NOT to install 160 degrees thermostats? Tony’s tips suggest it should be done as all Cummins latest are.. many have changed, and over here with 40degC days I can’t see any harm in a bit of headroom with engine temps. I also plan on adding redundant alarms too eventually getting rid …

      June 8, 2020 at 6:58 am My average seasonal (April – November) fuel burn includes running 5 knot channel/no wake zones, cruising at about 10 knots, some higher runs for weather/sea conditions, drift fishing, running at high idle to top house batteries when anchored out on cloudy/rainy days (I have an 8 amp, 16.5 volt, 130 watt solar panel). For 15 years, my seasonal average is 2 GPH.

      April 22, 2020 at 8:16 am There are a few things I can tell and a few things I cant tell from that pic. What I can tell is that you have proper insulated dry riser to a shower head style mixer on the down slope. That is good. Looks like most of the available height is being used and that is good. It looks like someone put a decent quality insulating wrap on and that is also good. The raw water is coming in at a good angle near the top and somewhat tangent to the OD so…

      March 29, 2020 at 7:00 pm Think “misting” if that helps —— What’s done is done, so move past this and do better down the road. Tony

      March 24, 2020 at 5:13 am Hi Guys My boat is currently stuffed full of piping going everywhere (water and fuel) and also runs some very undersized racors (which have done the job for years admittedly for the 6bta330’s) Fuel pipes are a combo of 12mm copper (which is looking worse for wear after 22 years) and made hoses (ie properly made with crimped ends like hydraulic hoses) To make things tidier and simpler I want to repipe and filter (probably a double filter se…

      March 27, 2020 at 4:02 pm at a whopping 5’6 and 72kg it is a bit easier to move around in there (the only benifit of being a short ass, had to be one ) . I can sit next to the engines on both sides of them bugger all room in front of them and access above them if needed means pulling up more floor , good to know you can use the flexi hose and clamps for the low presure side . my parts came from seaboard yesterday great service faster than coming from eastern st…

      March 13, 2020 at 12:01 am HI Wayne They dont have to be.. but I think its recommended as they hold tight and are generally well made – I have used them where I want to make sure they hold and i use them in pairs, generally. Make sure you get the 316 Stainless ones! Oh just checked and hosemart dont carry them (was asking about some other hose) EPE in Bibra lake or online then.. Steve
