The USCG Local Notice to Mariners (LNM) was just sent today. It announced many more conversions to Synthetic AIS AtoNs or Virtual AIS AtoNs, including many aids in my local area, the Detroit River, Lake St. Clair, and Lake Erie. Here is an excerpt from the LNM: ATON DECOMMISSIONING Lake Erie - Toled...

Have you read the REFERENCE section article on the Boston Whaler 15-foot hull ? Have you read the section of that article under the subheadings "Dimensions and History" and "Description" ? That article first appeared in 1999. I don't know that I have any other information on the ...

The voltage drop in a conductor that feeds a secondary power distribution panel from a primary power distribution source will typically not be affected by outboard engine starting currents because typically those currents do not flow through that conductor. In the problem being analyzed in this thre...

The use of AIS synthetic or virtual aids to navigation is not restricted to the Great Lakes, and, in fact, that is probably the opposite. AIS ATON devices have been in the process of being deployed at many coastal areas, and the are just now coming to the Great Lakes. The use of an AIS ATON at the M...

The capsized boat was the LEVIATHAN II, a 65-foot vessel. The tour operator's website gives some details:

Yes, but the whole point is to know if your display shows targets other than VESSELS.

For example, does your display show AIS BASE STATIONS? Does it show AIS Aids to Navigation?

FURUNO has announced a rebate program that offers a $200 rebate on the purchase of: --GP1870F 7-inch Chart Plotter and Fish Finder with Internal GPS/WAAS receiver --GP1760F 5.7-inch Chart Plotter and Fish Finder with Internal GPS/WAAS receiver The MSRP of these products are: --GP1870 = $995 --GP1670...

My concern is for the chart plotter display of AIS data from an Aid to Navigation (AIS ATON). Most of the chart plotters out today are really intended to show other VESSELS on their AIS display. I suspect they may not be ready to show AIS AtoN targets. I would like to get some reports from users of ...

The best solution to the very common problem of electronic devices on small boats being re-set or rebooted when the outboard engine is started is as follows: --install a separate battery for use with the electronic devices on the boat --isolate all electronic loads to the separate electronics batter...

I believe that the KEVLOK battery hold-down straps used on classic Boston Whaler boats were custom assemblies made from components manufactured by AGM CONTAINERS. AGM CONTAINERS has a website that shows their custom assemblies: http://www.agmcontainer.com/tie_downs/customassemblies Can you give the ...

No one can know how your boat is wired from your description of the behavior of your chart plotter. What is evident: the battery voltage is sagging too much during engine cranking. The remedy: reduce the voltage sag in the engine cranking battery during engine starting. To reduce the voltage sag in ...

A repeat of my earlier question: Does your chart plotter display synthetic or virtual ATONs created by AIS transmissions?

Regarding how to handle the plugs for the through-hull drains, see the owner's manual:

The gel coat layer in a Boston Whaler hull built to workboat specifications (or a red dot hull) is not likely to be particularly thicker than in a regular hull. The portion of a hull built to workboat specification that is thicker are the layers underlying the gel coat layer. A thick layer of gel co...

The NTSB report explains the cause of the capsize and deficiencies in the ballast, the launching method, and the trailer.

Based on a drawing contained in the owner's manual on the folio marked Page 10-4, the four switches on the dashboard of a Boston Whaler SL 16 boat were for --Navigation lamps --Instrument illumination lamps --Bilge pump --Accessory circuit Those four switch functions are the same as my earlier specu...

Thanks for that great link to an index of old Boston Whaler owner's manuals that are available on-line. I added that information to the REFERENCE section. It appears that the owner's manual for a c.1990 Boston Whaler SL 16 is found at http://media.channelblade.com/EProWebsiteMedia/2904/Owner's%20Man...

This discussion is a bit tangential to the usual strictly boat oriented topics, but I would like to solicit advice from the cadre of wood-working experts that read this forum. I would like to have a power saw of some sort in my home workshop in order to do some basic carpentry work. I envision that ...

Considering the EPA regulations that prohibit the tampering with any part of a regulated engine that can affect exhaust gas emission, it seems possible that you might not even be able to buy an ECM without demonstrating that you had the appropriate model engine for its use. The easiest way to increa...

Considering the following factors: --the present engine is if good condition, runs well, and exhibits good performance, --the cost of a new replacement modern engine is staggering, --the present value of the present engine if sold off will only offset a portion of the new engine cost, and --the pres...

DOUG--you were probably using a link that was not working any more. I made a new custom 404-NOT FOUND error page to help people who keep trying old links that are dead now.

The Marine Equipment Trade Show ( or METS) is held annually in Europe and is said to be the world's largest marine trade show--although perhaps the Miami International Boat Show might argue about that. The 2015 METS will be held in Amsterdam on November 17, 18, and 19. During the show various Design...

Hey guys--thank you for coming back to the new forum and re-registering. It gives me a lot of pleasure to see so many old hands returning. Your kind words about the website's return and the new forum are great to hear. It took a lot of work--computer and internet work--to get this accomplished. Ther...

Regarding modern outboard engines and their sound signatures, the increasing use of four-cycle engines has resulted in an interesting change in the sound signature. The four-cycle-power-stroke engine only has a combustion cycle on every other revolution. A two-cycle-power-stroke engine has a combust...

I have not experimented with adding sound deadening material to an outboard engine. I do have some experience in trying to control transmission of sound from my work in designing and constructing professional audio mixing control rooms. The sound of an outboard engine at half-throttle to full-thrott...

It is possible your boat electrical system could have a stray load on the boat battery even when all four dashboard switches are in the OFF position. There is no guarantee that someone hasn't wired an electrical load directly to the battery. I recommend you make a detailed sketch of the electrical w...

Cruising at 30-MPH and only burning 4.25-GPH suggests a fuel economy of 7-MPG, which seems very, very good. I believe the Suzuki DF140A is the most popular engine in the Suzuki line. It is really their high-output 115-HP engine, a high-performance version of their standard 115-HP model, and both are...

I really like the method Don used to raise the transom height of a classic 13-footer to accommodate outboard engines with 20-inch shaft length. Adding the flat transom insert is a really good idea. Boston Whaler did that themselves on the 15-foot hull's transom, which is otherwise quite curvy. They ...

At the moment the only Synthetic or Virtual AIS ATONs I can find are the four marking the center passage under the Mackinac Bridge. For recreational boats those AIS ATONs have very little utility. Most of us can find the center span of the enormous suspension bridge and navigate between the two towe...

Several years ago I changed to an E-TEC 225-HP engine from an Evinrude carburetor 225-HP engine. The reduction in fuel consumption has been significant. I reported some data on reduced fuel consumption with the E-TEC in these threads from The Old Forum: E-TEC Improves Fuel Economy 67-Percent http://...

The segregation of discussion of Boston Whaler boats made after the epoch of c.1990 into its own isolated forum ended years ago. The "Post-Classic" designation was always a bit controversial in itself. Heck, now some of those 1990's boat are looking more like classics when you compare them...

Performance is always related to weight and horsepower. If the hulls of a CONQUEST 23 and OUTRAGE 23 were the same, it is very likely the CONQUEST would weigh more. This would reduce the performance, that is, more horsepower would be needed to achieve the same boat speed with a CONQUEST version than...

Remove the stains again, using your preferred method. Then polish the gel coat in the stained area. This should reduce the porosity of the gel coat in that area. Then apply several coats of a good boat hull paste wax. Collinite Fleet Wax is a good choice. This will create a waterproof barrier in the...

Contact Boston Whaler customer service to inquire about the availability of their literature in PDF format. Boston Whaler customer service is extremely helpful and will go the extra mile to assist you. If they have the literature available in a digital format, they will be pleased to email a copy to...

My wild guess about your boat's MPG at a moderate cruising speed of 28-MPH is 2.7-MPG. I advise you to contact Boston Whaler. They usually have records of extensive boat tests for all of their more recent boats, and those boat tests include reports of fuel economy at various speeds. They usually pub...

Describe the switches. Are they bat-handle toggle switches? Are they rocker switches? If the switches are bat-handle toggle switches, they are usually oriented vertically and the usual convention is to have the ON position occur when the toggle is pointing upwards. If the switches are rocker switche...

Many people consider the Great Lakes region the best area to hunt for older models of Boston Whaler boats that are still in excellent condition. The colder freshwater of the Great Lakes and the seasonal boating contribute to increased longevity for boats used there. But even the oldest Boston Whaler...

I believe Evinrude offers the remote filler spout and cap as an accessory item. You can browse for it on http://SHOP.EVINRUDE.COM under the PARTS tab. Look in the category OB ACCESSORIES then select just about any model year (2010 works). Then subcategory FUEL/OIL. You'll find REMOTE OIL FILL KIT PN...

Evinrude uses the same size remote oil tanks with the E-TEC engines that were used previously: 1.8-gallon and 3-gallon. I think the fuel tank on an 1992 OUTRAGE 19 II (which I believe is the boat being discussed here) has a 76-gallons capacity. If you use a 1.8-gallon oil reservoir tank and get a no...

PETER--your explanation makes perfect sense. Thanks.

I am certainly in favor of taking advantage of substantial discounts on new outboard engines. If you can get an E-TEC 135 H.O. at a significant savings compared to an E-TEC 150, I think you should take advantage of that savings. I do not think you will be missing very much performance by choosing th...

I don't have any first-hand experience with the Evinrude E-TEC 135 H.O. engine. In fact, I had to look up the specifications to see exactly what model it was. I see it's the 2.6-liter V6 60-degree engine, which is used for the 150-HP and 175-HP E-TEC models. I don't know exactly what the difference ...

Epoxy is an excellent adhesive for making repairs to fiberglass composite structures. Be cautious with the method you propose to "pour [an] epoxy resin into the void". Curing epoxy is an exothermic chemical reaction, and a large volume of epoxy resin will generate a very significant amount...

I believe that most of the AIS ATON signals are intended to supplement the physical ATON buoys during the winter shipping season. Not too many recreational boaters are underway after December 1 in the St. Marys River and Straits of Mackinac. Not only will you need an AIS receiver to see the AIS ATON...

Many years ago (c.2003) we were cruising the Inside Passage behind Vancouver Island in the Pacific northwest. We were spending a night at a resort's dock and across from us was a 90-foot expedition yacht. About 3 a.m. I was awakened when the yacht fired up its big diesel engine and got underway. At ...

It will be interesting to see how various recreational chart plotters will react to these AIS transmissions from Aids to Navigation. Until recently, most AIS transmissions originated from vessels, and most recreational chart plotters were capable of displaying these AIS targets. AIS transmissions fr...

In February 2014 the United States Coast Guard (USCG) announced that it would begin to employ AIS Aid-to-Navigation (ATON) technology as a supplement to using actual physical aids to navigation such as buoys. (For more on the announcement see an earlier discussion in The Old Forum .) In recent LOCAL...

A corollary incident, problems with stability of a large vessel, was described in a prior article in The Old Forum. See Maritime Casualty: HOEGH OSAKA . A prudent master put the vessel aground on a sand bar before the list progressed into a complete capsize. That incident is still being investigated...
