On E-Bay boat parts, under "detroit Diesel", a set of tune up tools is available at http://cgi.ebay.com/ebaymotors/DETROIT-DIESEL-Tune-Up-tools-Deutz-tools_W0QQitemZ4629149778QQcategoryZ50441QQrdZ1QQcmdZViewItem I don't know enough to know which engines these are for nor whether it's a...

A mechanic I know and trust recommended RYDLYME (rydlyme.com) to descale (clean) the salt water side of engine cooling systems. He suggested it as a preventive procedure. Anybody have firsthand experience or knowledge of this product? According to him, there is little need to disassemble...

When is a good run time interval to tune up DD turbos? Different for naturals? Over the past six years since my port engine was rebuilt (and tuned) I've noticed my starboard 8V71TI has begun to be just a bit slower to start when cold during last season. It may also be smoking just a tad more...

Seems like a premade (completely assembled) oil change pump and manifold cost about $400 from the few I have seen. Maybe more now. Any recommendations for low cost products?? For do it yourselfers, you can buy a $100 reversible vane pump and make your own manifold for an oil change system. I...

When is it necessary to have turbo blankets changed for new ones? My current understanding is that they are OK unless contaminated with oil or fuel or both in which case they are a potential fire hazard. When the snap buttons fail, the blankets can be fastened with loops of external bare...

A current thread on "Window fuzz/trim" reminded me of a closely related issue which may be of interest. I removed an entire salon window frame to rebed it since it oozed water inside in one corner some rain storms. After removing external fastening screws, I hammered a putty knife between the...

Diesel fuel was listed in a Fox News review of LUNG CANCER this morning (2/8/06). I checked the Fox News Health website but found no details. Does anyone know the link between diesel fuel and lung cancer? Is there anything we need to do to avoid unnecessary risk aboard.

I'm wondering the best way to clarify discussion issues which arise during posting to a thread here. For example in the GFO thread on this page Banshee posted that GFO ruined a shaft..so I posted "How did that happen?" But I don't know if Banshee will return....It seems like those who posted...

In another thread (Following Seas) I posted the following website for reference on waves, http://boatsafe.com/nauticalknowhow/waves.htm I found one section particularly interesting: ".. Therefore, in order to classify wave height we determine the significant wave height, which is the...

Salt water residue on decks and windows drives me nuts. Can any Hatts run over 15 knots or so without spray getting on board?? Does greater forward flare on newer boats keep more spray off?? The major reason I began cruising at 10 or 11 knots instead of 16 or so was absence of spray onboard. I...

I'd appreciate feedback on the following issue. I've changed views over the last 7 years to that expressed below. Again I just read "turbos don't last as long as naturals" in the "52 53 refit" thread and that's also what Pascoe suggests via the "8V71TI and M 20 weak points" thread here. I...

Passcoe at http://www.yachtsurvey.com/boatreviews/Hatteras53.htm says: "...The primary weak point is the 8V71TI engines which have a poor turbocharger/intercooler system. The two part AirResearch turbos are held together with acorn clamps that frequently crack and leak. And the intercoolers are...

What's the interior wood on 1970's boats called? Are there different types of teak used? The owner of my YF told me AFORMOSA was the interior wood and when converting an aft double berth to queen, he was able to order matching wood from Hatteras for his carpenter..around 1980. ZEBRA teak also...

Someone said there is a prior thread on the above subject. Is it a "General Discussion" item? Anybody know what page to find it?? Thanks.

Has anyone had experience with periodic preventive cleaning or flushing of engine cooling systems. Does Detroit Diesel recommend anything in particular? Salt water or fresh water side? If fresh water coolant mix is kept up to snuff on the fresh water side and engine temp is ok, is periodic...

Low sulfur diesel fuel has caused significant problems in some diesel engines in Canada, including Cummins and Catepillars, for example , I believe. It's coming to the US..either this year or next. Various components have failed in some engine models among some brands in Canada. Last I saw...

About five years ago I put two cameras (mounted on a 2 inch square circuit board) in my engine room and a five inch or so security monitor, very compact, aboard on my flyrbidge. Parts from Radio Shack. I discovered two problems which kept me from using it much, but the system does work. In the...

:rolleyes: Are these the only clear materials for soft enclosures? What are the pros and cons of what's available?? Relative costs? Do most use 40 mil thickness? I upgraded with Strataglass and it's sure clearer than plain old vinyl, but I never got a clear understanding of how it compares to...

I stumbled across an August 1976 DD publication, "DETROIT DIESEL ENGINES for marine pleasure craft models" . Here a few excerpts of interest: "...No effort is spared to make a Detroit Diesel one of the smoothest engines you can install in your boat. There is, first, the inherent smoothness of...

Does anyone know if 1972 YF came with a 15KW genny as the brochure says? The original Hatteras paperwork does show a 15KW Onan for my specific boat, but I found out the hard way (from the genny specification plate on the genny) it's really a 12.5KW Onan. Thinking it was a 15 KW ONAN, I had the...
