I just checked a NOAA chart, and it looks to me like you are wintering over at 44° 59.4' N.

Go to the FAQ section and most info is there. Please give the URL to the FAQ section that has additional information. On the webpage at the URL mentioned above, I did not see any information provided on the topics I asked about. A URL to the answers would be much appreciated by me and perhaps other...

After you purchase the $150 module, what else to you need to connect the module to the engine? Does the module just plug into a connector already on all Mercury engines? Does the module sit under the engine cowling? Is there a space provided for it on all engines under the cowling? Do you need to ha...

Your decision to buy an older 13-foot Boston Whaler for use as an open skiff on protected water is a good choice. Powering with 20 to 25-HP is also a good plan. Your inquiry has too many questions for a cohesive discussion. If you need advice on a particular topic, you should post separate inquiries...

I was hoping there was a combination usb plug and voltmeter with some type of an auto off feature. Re having an "auto off" feature: this would be best implemented by using a mechanical relay to completely disconnect the USB circuit from the battery. The relay coil would be controlled by a...

RICH--you've got a nice boat there with the ribside model--a very unique Boston Whaler. I don't know for certain exactly where on a c.1971 OUTRAGE 21 you''d find the stencil number, but I would carefully look in any forward lockers. I assume you're hoping to perhaps reveal it, so I understand you'd ...

PAUL--your kind comments are much appreciated.

The most common method of providing a 12-Volt power distribution on a boat--even on a 13-foot boat--is to have a MASTER BATTERY ON-OFF switch. When the boat is not in use, the master battery switch is set to off. This disconnects all loads, with the exception of special loads that are desired to rem...

If a device with a constant quiescent or parasitic current of 0.015-Amperes is connected to a storage battery, we can calculate how long the battery will hold a charge and how long it will take for the parasitic current to dissipate that stored charge. At a rate of 0.015-Amperes, the device will con...

The selling price must be some fraction of the present replacement cost. Check with a Boston Whaler dealer to see what a 170 MONTAUK sells for in 2019. Then apply an appropriate markdown to make your boat attractively priced. If the boat is in like-new condition, a discount of 20-percent or more fro...

Regarding having a voltmeter associated with a USB outlet: Does the voltmeter monitor the 5.0-Volts of the USB outlet? Or does it monitor whatever the supply voltage to the USB outlet that is to be converted to 5.0-Volts? It seems a bit confusing to me to associate a voltmeter with a USB outlet if t...

None of the recent suggestions overcome the initial objection to having a digital Voltmeter display that is always on, thus always drawing current. The suggestion of using a switch to control the branch circuit has been rejected by the OP. I could add a switch to the circuit or run it through the ma...

To find an inexpensive source of thin and somewhat flexible sheet metal, visit a big box store and look in the kitchen accessories department for a baking sheet. Use that metal. Cut with a metal shear or tin-snips. Use a piece of wood as a metal forming brake. Visit a local vocational high school an...

Bend thin sheet metal to a U-shape that straddles the transom in the area where the auxiliary engine will mount.

A 20-year-old non-running 100-HP engine is probably not worth a complete overhaul and repair. Its other parts may have some value as used parts, particularly if new parts for the engine are no longer available. The value cannot be known without seeing the engine, as the actual condition of the engin...

Re the speed potential for an OUTRAGE 25 with 500-HP, I would think 50-nautical-miles-per-hour or 57.5-MPH would be in reach without much trouble, as long as the total weight was not excessive. But you probably wouldn't like the ride in any sort of open water at that speed. Since you have one standa...

If your recollection of only 4,400-RPM engine speed at full-throttle is accurate, the engines are about 1,000-RPM below where you should be aiming. Figuring a 2-inch change in pitch will give about 400 to 500-RPM change in engine speed, an old rule of thumb, then you ought to reduce pitch by 4-inche...

JTC--thank you for the very interesting narrative regarding how ingress of seawater eventually caused significant delamination of the bond between the outer hull laminate and the cured internal filler material of your Boston Whaler Unibond hull. I would hypothesize that because of the nature of wate...

Yes, I have the same experience. When I use an open-cell material to soak up water--a sponge--it gets heavier because the water flows into the many connected open passages in the sponge. I cannot imagine that anyone has ever tried to make a boat using a material that acts like a sponge to fill the s...

BOBBY--I see that no one has responded in a week. Let me then offer a few comments. I do not infer that the boat being a BASS BOAT model and having the characteristic of being "rare" is necessarily something that adds value. The BASS BOAT model was not sold in large numbers, which probably...

What an experience! Not many could say that. Yes, it was amazing that I was aboard the actual AC winner, and even cooler that I got a turn at the helm. There is a small fleet, about four or five, retired 12-Meter boats in the harbor at Sint Maartin, and you can go "racing" on them for a m...

We were briefly north of Latitude 45-degrees-North last weekend. When we arrived the shoreline of Grand Traverse Bay was beginning to creep outward with ice cover, and there were some impressive icebergs floating around in the open water offshore. The overnight low-temperature was about 0-degrees-F ...

Archie--your situation reminds me of the old humorous saying: Q: How many psychoanalysts does it take to change a lightbulb? A: It only takes one, but the lightbulb has to really want to change. Applying this to your situation, you can get that T-Top removed, but you are going to have to REALLY WANT...

I want to make three important disclosures regarding my relationship with Australia: --I have never been to Australia; --I read "The Thorn Birds" back in the 1970's; --I stayed up to 3 a.m. every night for a week in January 1987 to watch the live broadcast of the America's Cup race from Pe...

Bob--thanks for the cite to Wikipedia. As I mentioned earlier, Boston Whaler Unibond hulls are filled with foam, not with sponges. I don't know where the notion arose that Boston Whaler uses sponges in their Unibond hulls, but apparently this misinformation is out there somewhere. I can't believe th...

Lippert Components Inc., the company that acquired Taylor Made and other marine-upholstery businesses in the past few years, has recently filed a lawsuit against its former president, Scott Mereness, charging that using confidential information Mereness made personal investments for his own benefit ...

Other factors can affect the range of Class-A and Class-B AIS signals, but those factors are not inherent in the limitations of the devices. For example, the antenna on a ship with a Class-A AIS may be more than 100-feet above the water, while the antenna on a recreational boat with a Class-B AIS ma...

Regarding Class-B AIS devices, there are now two categories of these devices on the market. The older or traditional Class-B devices used a carrier sense time division multiple access technique (Class B "CS" or CSDTMA) to know when it was polite to transmit, that is, they listened for a fe...

It is hard to predict in the future when the current engine needs replacement, how much a Yamaha 70-HP four-stroke-power-cycle engine will weigh. Those engines have been getting steadily lighter in weight. If you want to use 253-lbs as the benchmark weight for a new outboard that in the future you m...

Most important: before you disassemble the wiring to the switch in the console at present, take a good digital image of the switch and wiring, make a sketch of the wiring, and mark all wires with temporary labels. This will allow you to re-connect the new (or old) switch without having to deduce the...

Another form of notation describing two power levels is to calculate the GAIN necessary to increase one power level to the other. For example, if P2 is increase by gain G, the result is P1: P1 = P2 times G This is easily restated to be G = P1/P2 We can say that a dB is related to gain G by dB =10 × ...

BOB--the two articles you wrote are both excellent sources of information and very nicely supported with illustrations. They are great additions to the website, and thanks, again, for your contributions.

I would look to draft behind a slower moving Semi. When towing my boat on the interstate highway, I often fall in behind a large truck that is maintaining about 60-MPH. I figure the truck has a professional driver who knows what he's doing. I don't try to get so close as to draft, but I try to keep...

Does this Guardian have a heavier layup [than some other unspecified boat]? If the boat you plan to buy that we are discussing was made as a commercial or government hull, the laminate schedule would typically have been thicker, stronger, and thus heavier than a boat molded as a recreational hull, ...

If you hate the T-Top, you would be farther ahead to sell the boat and buy another one like it without the T-Top. The T-Top will have significant value to another buyer. The cost of that T-Top was probably $10,000. It is worth more on the boat than off the boat, with your trying to sell it.

When I look at the reference site it shows the 21 [OUTRAGE] only having 9-inch draft... Read the REFERENCE section more carefully to find the years of production for a particular model. You have made an error in your thinking by associating at boat made in 1970 with a boat you think was made in 198...

The stern eyes appear to be solidly installed. I think the location they are in now is probably better for use as a tie-down to the trailer. For a towing bridle, I would get a metal ring about 2-inch diameter. Splice two lengths of rope onto the ring. Make the length of those two ropes just long eno...

I don’t recommend using advice based on older two-stroke-power-cycle engine experience as the basis for what should be done to a modern Mercury FOURSTROKE engine. Check the Mercury owner’s manual for advice. Since the engine is reported to run well, I wouldn’t start looking for problems that aren’t ...

The 21 Outrage made in 1970 has a 9-inch draft and has no relevance to a 21Justice.

It is not the original poster who has new tricks, but his local repair man. I doubt there are any really new tricks for getting large amounts of entrapped water from the interior of a Boston Whaler Unibond hull. There has been no change in the characteristics of the hull, the foam, or the water in t...

PHIL's advice regarding highway speed is cogent. I have towed my 24-foot boat perhaps 75,000 highway miles, and seldom exceed 62-MPH. It is common on a long interstate highway drive that the total number of cars I pass is zero. Slower speed at towing helps keep everything working longer, cooler, and...

\The Garmin is displaying 50-percent more fuel usage then what I’m actually using. In other words when I get back to the fuel dock and it displays 30-gallons used it will top off with approximately 15 gallons. The GARMIN is showing 100-percent more fuel used. If you only really use 15-gallons and i...

Any outboard engine made in c.2010 will be fine running on fuel of ethanol-gasoline blending at a 1:9 ratio. If you can easily find gasoline without ethanol, that is a reasonable choice, as long as that gasoline is fresh and from a source that has uncontaminated fuel. I'd rather get fresh, pure high...

I read all these articles about never buying engines with low, low, hours. Should I be concerned? I think you are past the stage of being concerned--you already bought the engine. I would not have any anguish about the low-hour running time on the engine based on something you read. From your own a...

Is there any maintenance I should do? Eight or nine years on the water pump is probably a bit too long, particularly for a Mercury engine, as I believe Mercury recommends water pump service at much more frequent intervals. I wouldn't stretch the water pump service interval too far past the factory ...

DUANE--I don't own any devices with a USB 3.0 port, so I have not experienced a problem like you are having. If the GARMIN device is as popular as you suspect, I would think someone must have figured out how to interface it to a USB 3.0 port. I can't offer any advice, except what you have already tr...

The vendor linked below may stock CONTURA switches with actuator covers with common legends (such as HORN): New Wre Marine https://newwiremarine.com/marine-grade-switches/contura-ii/ I like their switch for HORN because it has a distinctive red cover, making it easy to find on the panel: HORN Switch...

You can see th...

The OP has indicated that his local repair shop has expert knowledge of the cause of the appearance of a puddle of water under the middle of his boat in storage and also has expert knowledge on how to repair it with "new tricks" learned. I don't think further advice is going to sway the OP...

BC55--You are confused about switch nomenclature. A "toggle" switch does not mean the switch has a momentary action. Generally the term "toggle switch" refers to the type of actuator used on the switch. A toggle switch typically has a bat handle actuator. The term rocker-switch g...
