While i agree it's common in some larger vessels (and in fact law in some commercial applications) to have a third generator and panel(can be a battery bank set up) in a different location, we are i thought talking about specifically the bow! , there are numerous regulations regarding fitting...

Would love to hear further re your comment(Even on the hook , most boats ventilate from aft to fwd.) Every boat i believe i have been on is designed to ventilate from forward to aft, hence hatch's mainly open forward, dorades open/face forward, mainly all vents are towards the rear of vessel or...

If you are a pleasure rated(non commercial passenger) use vessel then normally the rules and regulations such as ABYC/RYA/Lloydd's etc dont apply but they do offer some very good idea's and prudent points such as: Glass or plastic tube or strip-type fuel gauges must be: 1) protected against...

Could only think of one reason to place in the bow and thats space constraints! There a lot of reasons how ever not to, such as 1) Noise and fumes and exhaust outlet (if in the bow) allowing fumes to run aft 2) Long runs of main trunk wiring and fuel lines etc 3) Possible weight issues where...

Eric, Yes all correct, how ever most of the more modern engine lubricants contain better additives regarding cleaning actions,saying that: we had a serious issue with our Cat powered(C12's and C18's) large seismic air compressors mounted on the rear deck of the supply vessel it was mounted on...

Moving backwards to my original mundane post-Have you checked the throttle is moving to the full throttle stops on the injection pumps? Is there enough air getting to the engines? Just saying!!

Eric, had to go back to the supplied course notes to offer some more info on that and the below are from those pages (not my work but no reference to give credits to(Perhaps credits should be to NORIA lubrication courses) -Im saying this as I have been warned by some members not to cut and...

If you have a three blade propeller you could change to a four blade as this commonly reduces the diameter by around 6 to 8% keeping the same/similar RPM, they also tend to be smoother in most cases,(although normally found on larger vessels) You could talk to a propeller expert about reducing...

Dont use a steel wire brush, USE brass brush or SS , there are various cleaning compounds you can use as well (if being careful)

Good choise , re the white packing more than likely is a Teflon based packing, by the way be careful if are going use Graphite impregnated packing in your marine underwater applications, these Graphite packing's are generally designed for industrial applications where dissimilar metals and sea...

Above post really says it all, either love them or hate them, we have one vessel powered by four V16's (basically 2 x 8 cyl bolted together), we also run 4-71 series in the generators, all the above are from the mid seventies and still screaming along, we took the turbo's off the 16 cylinders...

Took part in a oil refresher course a few years back and believe they said most soot/carbon deposits are only around .03 microns in size(Memory recall!), how ever they can clump together to form larger particles. Individual soot particles normally pose little risk to engine parts, but clumps of...

Here you go Paul Scott below is from the manual and possibly a clear lead as to chase down re the legality QUOTE:Official Incorporator : The Executive Director office of the federal register washington, d.c.

So would I! But this was cut and pasted from my copy of ABYC as is the following reference: Based on ABYC's assessment of the state of existing technology and the problems associated with achieving the requirements of this standard, ABYC recommends compliance with this standard by August 1...

Well, therefore i stand corrected as what I have commonly seen in these forums is a high degree of confusion then regarding Galvanic corrosion issues (normally called in the boating public Electrolysis -which is wrong),as there are/have been so many posts on these issues Now when you consider...

Saw one turned into a great ice box (full of "cold beer") and the top was hinged and acted as a nice table top (complete with recesses to hold that "cold beer") Hmmmmmm

Here's A CUT AND PASTE from my manual ABYC H-33 Diesel Tanks and installations, just the high lights re venting Legally Binding Document By the Authority Vested By Part 5 of the United States Code § 552(a) and Part 1 of the Code of Regulations § 51 the attached document has been duly...

Just to note here it's not really comparing Apples with Apples how ever as the article uploaded is basically comparing wood with STEEL and IRON (NOT 316 SS or 316L). Both Steel and Iron and even Bronze have decades of recorded reactions with damp wood and yes wet wood will provide the...

Its time to check your fuel filters before doing any thing else also if still using the mechanical fuel lift pump check that as well,if it's a serviceable type they usually have a small very fine gauze inside which i have seen gummed up more than once, the injection pump requires a positive...

TO NOTE: Yanmar claims the new outboards fall well within the latest EU RCD 2 limits.

The main difference between the add on external oil filters is usually their micron size of between the usual 3 - 10 max micron, where as your standard spin on engine oil filter has a micron of usually 20, (some 10) that compared with the widely accepted theory that the majority of engine wear...

Fully agree with that, the more packing's is more for the larger shafts, the smaller shafts are happy with 3-4 rings, it can also depend on how the rings are cut (square or taper cut), These days with cheap laser temp guns it is a good idea to do a test run before tightening to much at all ...

We have been using the Yanmar diesel outboards (D27 and D36) for many years and still do, (although out of production some years back) the last units we purchased around 2010 out of Australia cost AU $ 24'790,(36 hp) These units take a beating from our third world boat crews but keep on...

The normal recommendation by numerous packing gland manufacturers is 4 to 6 rings depending on the actual stuffing box design, only three quite often means you have to compress the packing's more to create a good seal, which can lead to premature shaft wear

Before running off to get your prop's re pitched have you checked the actual RPM with a laser tach or similar (Depending on tach model and how it's driven 10% error is not out of the question) couple of following items to note as well, 1) Do you notice any black smoke when at full RPM? 2) Have...
