    • 6BT 210hp RPMs increasing on their own

      This topic has 7 replies, has 3 voices, and was last updated byGary Marshall 1 year ago

      October 26, 2022 at 6:22 am Hi all, My partner Allan had his 6BT rebuilt recently and has been using it about 2 weeks now, prob put on about 100-150 hours since the rebuild. Just yesterday the rpms in idle started increasing on their own. He thought it was the cable, but disconnected the control cable and the same thing happened. He can use the idle screw to bring them back down, but then when he restarts the engine, often the rpms are too low. He is using a “newR…

      November 6, 2022 at 1:54 am Thanks. It is good to have that specific knowledge just in case he needs to get the pump done.  As mentioned, it’s Barbados, so there are not a huge lot of options in terms of shops that do this sort of thing. Don’t know too much about this particular person. Good to know that the price is fair. Labour tends to be cheaper here, relative to the US, whereas imported parts would cost quite a bit more.  He did go fishing yesterday for 10…

    • John Deere Engines Vs Cummins in commercial fishing application

      This topic has 2 replies, has 2 voices, and was last updated byGary Marshall 1 year ago

      April 3, 2022 at 4:06 am Hi Tony and all members, At some point I will look to step up in boat from my Albin 28 (w/ Yanmar 6LPA-STP) which is currently commercial fishing with 9,000 hours (Barbados) Most locally built commercial fishing boats in the 30 to 42′ range are powered by John Deere engines. These are imported from a near by dealer in Grenada, are relatively reasonable, and straightforward engines, and are good on fuel. The specific engine I was quoted for…

      April 3, 2022 at 4:46 pm There is no local dealer support for Cummins or John Deere in Barbados. However, there is a John Deere dealer in Grenada that provides John Deere’s for Barbados. Cummins is also a popular brand here, but again, no local dealer support. John Deere is probably the easier local option, but Cummins has the “Tony Athens” advantage, where I can turn to this forum for help. I am still weighing options. One option is a locally built bo…

    • New Diesel Engine owner (sorry, it's a yanmar) 1 2 6 7

      This topic has 126 replies, has 6 voices, and was last updated byGary Marshall 2 years ago

      April 29, 2017 at 5:55 am I just wanted to greet everyone. I just bought my first Diesel. An Albin 28 2005 model flush deck powered with a 315 yanmar. I wish I could have gotten a cummins B series, but that just isn’t available in the flush deck design I wanted. That said, I will be reading and researching as much as possible to keep this engine working well for as long as possible. It is the original engine, and had about 900 hours on it. It was in fresh water mos…

      March 3, 2022 at 5:34 am Hi all – Long post warning… 🙂 Just wanted to document what modifications I have done so far with my exhaust. I am a novice, and learning, so critical comments are welcome. I removed the exhaust elbows off the engine and inspected the turbo. It looked similar to my previous inspection in late 2017, with some rust present, but the flan blades and such still looked in good shape. Of more concern was the unevenness where the elbow bolts onto. I did …

    • Understanding exhaust hose & pipe dimensions, and making fiberglass tubing

      This topic has 11 replies, has 5 voices, and was last updated byGary Marshall 2 years ago

      November 3, 2021 at 4:01 am I know Tony has a nice article which mentions some of this @ “https://www.sbmar.com/featured-article/everything-you-need-to-know-about-marine-exhaust-systems/” but I am still not 100% clear. I have a 4” hose coming off my yanmar 316 6lpa mixing elbow (aftermarket cast 316 stainless, but identical to oem part in dimensions). So, this exhaust hose inside diameter is 4”. If I install a lift muffler after this hose, therefore the ou…

      November 15, 2021 at 12:37 pm Right now the exhaust exits out the side of the boat, but close to the transom. I’m not sure that having a shorter run, if it doesn’t utilize any more height, can help the backflow situation. I have a couple ideas working with, which I will share, just didn’t get chance to do any work on it this last weekend.

    • Understanding Lift Muffler Operation

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

      November 2, 2021 at 1:48 pm I have been pouring over Tony’s articles on exhausts, wanting to improve my own. I would like to understand the lift muffler operation a bit more. Designing a Marine Exhaust System When the engine is in operation, how full is the lift muffler? Does the pressure of the exhaust gases keep it practically empty, so it is only the water draining down the hose from the mixing elbow which might drain into it when the engine is shut off? As if i…

      November 3, 2021 at 2:47 am Thanks Tony. While I read all these articles a few years back, they seem a lot clearer to me now with the benefit of a bit of experience. I understand better now, so it looks like what you have labelled as the “muffler dip tube” should extend down fairly close to to the bottom of the lift muffler, say 3 or 4 inches off the bottom, and the water level would stay in line with the bottom of the muffler dip tube when engine is on. Does a…

    • Control Cable connection to ZF63A

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

      November 20, 2020 at 3:21 am Hey guys, I hauled the boat for annual maintenance and was cleaning up the transmission area, and found 2 issues I want to resolve. 1) the control cable is attached to the lever using a ball joint, just like you sell (https://www.sbmar.com/product/smx-c33-control-cable-ball-joint/) . But what I find odd, is that the control cable can very easily slip off the ball joint connection. The upper part of the cable sheath is still firmly connected, but…

      November 20, 2020 at 7:55 am Thanks Rob. I don’t post much these days, but enjoy reading your helpful responses whether on sbmar or over on the albin forum. It’s appreciated! Not being too familiar with the connector, didn’t realize it had a spring tension in it. I will email Russel for both. G.

      April 1, 2018 at 1:25 pm Firstly, apologies as i have been away from the forums for most of the year so far. The boat has been working well thanks to everyone’s help, and we have been having a great fishing season so far. i’m just taking a a break this weekend for Easter. This time of the year is both our main fishing season, and also our baiting season when we work nights as well to catch ballyhoo. I was just curious about the sbmar vacuum gauges, as the…

      June 7, 2017 at 5:43 pm When I reply to a post, the font is very light when I am typing and so I type my response in Word and then copy and paste it in here. However, often the Submit button disappears. Anyone else with this issue? I am primarily using Chrome, but had to switch to Internet Explorer in order to still see the submit button. Anyone else with this issue?
