To run or not to run…
This topic has 1 reply, has 2 voices, and was last updated by

April 15, 2021 at 10:05 am Curious what the pros say about a laid up boat in winter, whether or not to run engines frequently or just leave them be if the boat will not be moving. I’ve heard that unless a diesel engine is under load there is no point in warming them up just to shut down again. Thanks
1 ReplyApril 15, 2021 at 10:32 am Hey todd FWIW I have VP D6 w/ IPS and if nothing else the manual recommends starting every two weeks just to circulate the water in the exchangers. I think this has to do with minimizing the corrosion potential.Last Post by:

O-ring with FS1000 filter
This topic has 1 reply, has 2 voices, and was last updated by
3 years ago April 3, 2021 at 10:21 am I bought the Double Muti Filter kit and the FS1000 came with a small O-ring, but the other filters did not. I’m assuming this small ring goes on the threads of the filter head before you screw on the filter. Someone explain the difference to me please. What exactly is the small ring for?

Fuel lines
This topic has 1 reply, has 2 voices, and was last updated by
3 years ago April 1, 2021 at 2:06 pm Picture enclosed shows my fuel line to my fuel cooler.Not sure if the cracking on the rubber is crucial for these fuel lines.Not sure how these fuel lines are constructed.If it was a regular hose I would replace it.If the fuel line should be replaced I would think about removing the fuel cooler as I think the fuel lines are expensive.Any input appreciated. Bill
1 ReplyApril 1, 2021 at 6:39 pm Lose the cooler and the fuel block and you will have eliminated several potential leak points and hoses. Itās a fairly simple project. I have done this a year ago on one engine and and spent following season monitoring and comparing the engine with cooler vs engine w/o cooler. Fuel on non cooled side runs only 4-5 degrees higher. And that is after 6+ hours running. Not to mention easier impeller changes. I will be removing the other side. Back t…Last Post by:

Hydraulic Steering

March 30, 2021 at 6:24 am Hi, looking for advise on our hydraulic system. We have purchased a 1984 Hudson Force 50 Ketch – 25tons – with a Dual Helm Hynautic Steering system MS-1150/1175/1200 Helm unit H41, Cylinder no. K-3. We have a long run keel and a very heavy full length rudder. All is ok under engine and the helm is reasonably light, however under sail, and especially when there is some weather helm it is a different story. The steering becomes so d…
1 ReplyMarch 30, 2021 at 7:39 am As a long-time sailor I can say that the correct way to fix the hard steering with “some weather helm” is to correct the weather helm. Basic sail trim. I had a similar noise problem on my current boat with hydraulic steering, dual station, when I bought it. The solution was a very thorough purge of air in the system. I don’t have any special bypass valves or the like, so I just kept adding fluid to the upper helm as needed and …Last Post by:

3 years ago December 21, 2020 at 7:58 am I have twin 6bta’s Cummins Diesel 370HP about 700 hours on each. My current max rpm is 2850 and I have read on this forum that the ideal rpm should be 3150 at WOT. What would be the benefit of getting my props properly pitched?
12 RepliesMarch 30, 2021 at 3:29 am Harry, yes a percentage delta vs. a fixed delta can be expected. Easy enough to verify at the dock with a fully warmed up engine.Last Post by:

6 RepliesMarch 24, 2021 at 11:43 am We just put in an offer on a boat and it was accepted. Survey is Tuesday of this coming week. This boat was #7 on our list. The boats in the Great Lakes are not on the market for very long. We have missed out on a few so we had to get aggressive on this one. There was a boat 50 miles from us…… But it was in Canada so we had to pass since we could not cross to inspect in person. I am still waiting on the service records for th…Last Post by:

Fresh water flush while on mooring, issue with this exhaust?
This topic has 3 replies, has 3 voices, and was last updated by

March 19, 2021 at 7:27 pm Have read many articles here about fresh water flushing, but most require a water supply. I’m on a mooring, so the only water available is what I have remaining in my water tank. Have twin 5.9 380 QSBs, 1000 hours (only 20 hours in salt from my use late 2020). 100% ocean water going forward. I came across a post from last July by Robert Vetrano (vessel Knot Flying) where he adds a 1/4 NPT barb fitted to the pressure side of his water …
3 RepliesMarch 20, 2021 at 6:30 pm Thanks for the confirmation on exhaust for engine off water flushing, and secondly for guidance for penetrating oil on the turbo flange bolts. Wasn’t sure if there may be anything else regarding those bolts to be concerned about, but sounds straight forward. I have plenty of Kroil penetrating oil left over from my SB aftercooler kit. I serviced my aftercoolers just weeks ago, and they came apart without trouble (and are now properly lub…Last Post by:

In-the-water packing break-in
This topic has 2 replies, has 2 voices, and was last updated by
3 years ago
March 17, 2021 at 5:06 am Just a general question, more or less to compare notes and get an idea how others do things. How do you run-in new shaft packing in the water? I generally set them relatively gently with a light trickle of water and find that they slow down over several hours of running and then can be “fine-tuned”. It’s ideal when I have access to the boat and can go make the adjustments myself. I have a customer that disagreed and opted t…
2 RepliesMarch 19, 2021 at 3:42 am Thanks for the reply, Tony. I actually had looked at all your articles on shaft packing. Eventually I plan to add a lathe to the shop, but never thought about using it to break in packing. That’s a great idea. I basically pack all mine the same way, but will consider adding the grease fitting from now on. When I repack a stuffing box off the boat, I push a tapered end of a shaft through the packing to “open it up” before t…Last Post by:

How to remove then prevent Vertigris on my Groco seawater strainers

2 RepliesMarch 15, 2021 at 6:37 am Using 10:1 mix with common HCL ( pool acid) & water does wonders.. Then scrub wash with soap & water– Keep all “wet” with WD 40 down the road..

January 11, 2021 at 10:13 am I have a fresh rebuilt 6BTA in a boat I have been restoring for a couple years. I am getting to the final stages and did a test run in the driveway yesterday with an issue that has me at a stop. My issue is after starting the engine, it runs for a few seconds then shuts down. If I hold the fuel shutoff open it will continue to run. If I disconnect the alternator input to my smart combiner the issue goes away. I do not have a diode wired in at t…
7 RepliesMarch 1, 2021 at 7:28 pm Thought I had this under control but the issue came back. Went to do final runs today before I move her to a slip this weekend and it went back to shutdowns. This time the issue was pretty intermittent, sometimes run for only a second, sometimes 20 or 30 seconds before shutdown. So I went back to the drawing board, made sure everything was matching my diagram and started metering for drops. No voltage drops noted, just immediate shutdowns. So I…Last Post by:

No Seawater strainer?

February 23, 2021 at 7:35 pm 2001 QSM11’s on a 42 convertible and I noticed today (pre-purchase) that there are no sea water strainers on the raw water system. This “feels” like a bad design, but i’d like to believe there was good rationale by the boat builder when built. Should I move adding strainers to the top of my must-do list if survey is successful? Picture on next post.

Extra gauge space
This topic has 3 replies, has 4 voices, and was last updated by
February 21, 2021 at 6:44 pm I’m installing a hart tank tender system in my boat this spring and eliminating the unreliable electric gauges . If you had two free gauge openings at each helm, what would you add for gauges? Exhaust temp, water pressure, boost pressure? Engines are 6BT mechanicals with standard oil pressure, water temp, volts, hours and tach. No transmission gauges. Thanks.
3 RepliesFebruary 25, 2021 at 9:20 am EGT & BOOST. Can be combined in the Turbocator. If this is a planing boat and I assume it is then these are two of the most important guages to have. There are lots of choices but those two can warn of overloading the engine far earlier than other means. After than then maybe a GOOD alarm system incorporating raw water flow loss, coolant over temp, gear overtemp and so on. These can be done with temperature sensitive switches chosen …Last Post by:

Yanmar motor mounts (isolaters)

5 RepliesFebruary 24, 2021 at 9:35 am Sorry it has taken so long to get back to you. I’ve been “on the road”, so to speak. I was able to find the original, old fashioned style mounts. So I can not really say anything about which R&D mount to use. Although, I just remembered that a friend of mine just purchased some R&D mounts. I will check with him and find out which ones he got and how they work. He also has 4LHA-STEs. Standby. BillLast Post by:
