Q3: what actions have you taken to remedy the loss of electrical power to the helm console after you concluded the circuit fault was in the ignition key switch connections? Just your assessment that the fault must be in the ignition switch circuit connections does not explain how the problem was act...

ASIDE: When I suggested that you use finer-pitch threaded fasteners (higher number of threads-per-inch) I was going on my own intuition about those fasteners giving better attachment into thin materials. I searched for more advice on using higher TPI fasteners, and found this discussion, which seems...

I would use alcohol to wet the water and make it tend to evaporate faster. Acetone is more expensive than alcohol, and it might be harmful for the wood and foam in repeated applications.

If there are large areas of the hull with no original gel coat intact, I would use epoxy resin to seal the hull bottom and sides. Then build up the lamination of cloth and epoxy resin as necessary following the instructions from Boston Whaler. Sand and fair the entire hull, and paint it. Using epoxy...

Q1: what is the cause of the odor and apparently pressure build up in the fuel tank? The fuel tank is not properly venting; the vent mechanism may not be working as intended. Check the tightness of all the worm-gear hose clamps seen in Figure 1. Q2: are those worm-gear hose clamps part of the OEM i...

I plan to sand-off the bottom paint and yellowed gel coat, leaving the original white gel coat in place, then apply a fresh layer of fiberglass, barrier coat, and new gel coat. I do not plan to add anti-fouling paint to the bottom. Your plan will add considerable weight to the boat, and required en...

Q4: did Boston Whaler use epoxy as the "binder" for the gel coat? Q5: did Boston Whaler use polyurethane as the "binder" for the gel coat? Neither epoxy or polyurethane were used for the gel coat layer. Boston Whaler boats are laid up using a polyester laminated resin and a poly...

FAQ Q2: Where is the hull identification number?
https://continuouswave.com/whaler/reference/FAQ/#Q2

...things can always be improved by a real use-case examples, and logically, it would have been a good peace of mind to know that transom water intrusion can't compromise and affect the hull in front. In the case of these plastic through-hull fittings that exit the transom below the water line, the...

Q7: is use of 3M4200 Adhesive (as recommended by some unidentified source) to bed the KING StarBoard material to the gel coat of the Unibond hull (in order to add strength to the attachment of the extension to the hull) a good idea? There are several possible problems with this idea. The principal ...

...6 x 4-inch base plate to be attached to the bow using four 1/4 x 20 bolts.... For attachment of a machine screw to a 3/8-inch phenolic board, I would not use 1/4-20 threaded fasteners. I would use a higher thread-per-inch, possibly 10-32 fasteners of higher strength than made-in-china-hardware-s...

Q11: has the particular 2004 190 NANTUCKET boat been used in saltwater or freshwater? Wood does not tend to rot in saltwater. But, somewhat paradoxically, if the hull interior is holding saltwater, getting saltwater to evaporate and dry will be more difficult than if the foam is holding freshwater. ...

Perhaps I have not explained the construction of a Unibond hull in a sufficient manner. I will try again. The Unibond hull is made of two parts: the hull and the liner. Think of these like a shoe box: there is the big box with an open top, and there is the lid for the box. This is exactly like the t...

This does not seem like a smart design from Boston Whaler. Boston Whaler has been building their Unibond Hull construction boats this way since 1959. This construction method is used in all Boston Whaler hulls. Considering the enormous growth of the company in the last 65-years and their present li...

Q10: how can I know if water has saturated the foam? Your question is a frequently asked question. An answer to your frequently asked question is given in the answers in the Frequently Asked Questions or FAQ section. Please read at Q3: Is there water in a Unibond hull? https://continuouswave.com/wh...

islavov wrote:Q9: can...water enter the foam that is between the outer skin [the hull] and the inside skin [the liner] below the engine splash well?

Yes. The Unibond hull foam interior is one continuous open space that was filled with foam. There are no separate compartments of foam.

islavov wrote:Q8: is the bottom of transom connected with a hole with the foam between outer skin and inner skin where bilge is and fuel tank up front?

The Unibond hull foam interior is one continuous open space that was filled with foam. There are no separate compartments of foam.

As for what engine to recommend, if you want best reliability and best fuel economy, probably the SUZUKI DF115 is a good choice, and it will be less expensive than a 140-HP or 150-HP model. A good friend happens to have an OUTRAGE V-20 with a SUZUKI DF115, and it can certainly cruise at 25 to 30-MPH...

I have a 1984 OUTRAGE V-20 powered by a YAMAHA 250-HP Ox66 two-stroke-power-cycle engine. My first thought on reading that sentence is your OUTRAGE V-20 must be a rocket ship. That hull is easily driven on plane, and with that much horsepower I would worry about the stability at full throttle boat ...

ASIDE:

Q7: what is the purpose of the many machine screw fasteners with large washers on the transom of your boat as seen in Figure 3?

Q5: could [seawater] have leaked into the foam of the hull? Yes, see my reply above to Q4. Q6: should I worry about water intrusion past the transom and into the hull foam? Yes. There is ALWAYS a proper concern for any water--seawater or freshwater or rainwater--to be allowed to enter the internal ...

Q4: is the transom a separate closed compartment [from the rest of the interior of a Unibond hull]? No. The transom wood reinformacemnt is placed into the hull mold during the lay-up of the hull. The hull liner is created in a second mold, in a similar manner. Then, ostensibly while the polyester r...

The presence of a brownish liquid with some odor associated that comes out of an empty fastener hole from the interior of a Unibond hull is most likely the result of some uncured laminating resin, probably polyester resin, mixing with water.

I have not watched any of the 13-minutes of your recorded presentations, as I felt your narrative and photographs gave me a good understanding of the problem. This problem seems to be a common occurrence with that particular Boston Whaler boat model and age. Some other threads have discussed this pr...

...I’ve seen engines with anywhere from 400-hours. to 1,300 hours. I’m not sure how that equates with miles on a car engine in terms of how to think of the value and risk of need to replace. Propulsion engines on boats that operate at planing speeds are much different than automobile engines. The o...

I am familiar with the 23 WALKAROUND boat, from cruising with two friends who own (or owned) one, and reading of the experience of a third friend who also had one. The original Whaler Drive configuration was quite a complicated structure, and the unusual rigging tubes with their below the water line...

Q6: what amount of engine running hours is normal for the engines on boats that are 20-years-old? Most 20-year-old boats will not have their original engines. An outboard engine made in c.2000 might not be running in 2024 or not on the same boat, particularly if the boat was used in saltwater, and ...

I will check out a VANTAGE; I'm not familiar with it. I don't think there is much point in looking at a 210 VANTAGE. The 2025 (latest model) 210 VANTAGE retails at $156,000. The chances that you will find a 210 VANTAGE used for under $40,000 are zero. A used 210 VENTURA (which was the boat suggeste...

Unless there are obvious mechanical fasteners that retain the front cap of the console to the main console, the most reasonable method of attachment that does not involve mechanical fasteners would be the two laminated parts at attached with a very strong adhesive.

To go 20-miles out into the ocean for whale watching or angling with eight or more people you will need a lot more boat than a 210 MONTAUK. I don't think you can find too many really nice used 210 MONTAUK boats with a good trailer for $40,000. In a simple cursory search I see 210 MONTAUK used boats ...

Initial threads that ask many questions on many topics are generally very bad ways to elicit information. If you asks multiple questions the replies become all mixed together. It is much better to ask a single question or a series of two or three that are all closely related, rather than ask multipl...

There are some incongruities in your observations. First, if a 25-HP four-stroke-power-cycle appears to have the same power as a 40-HP two-stroke-power-cycle engine, the only reasonable explanation was the 40-HP was not running properly, may have been running on with one dead cylinder, or in some wa...

Q1: should I be concerned about a broken through-hull below the water line and under the swim platform on my 2004 190 NANTUCKET boat? Yes. If the through-hull fitting is below the water line and is not intact and completely sealed against penetration by water, there is risk of water getting into th...

There are many manufacturers of this style of breaker. Quality counts. PHIL T makes a good point. Buying the no-brand cheapest stuff may not pay off in the long run. A good vendor to use for marine surface mount circuit breakers is Blue Sea Systems and their 285-series, which sell for about $40 on ...

At the least, I think you should go to the dealer who sold you this new 2024 230 OUTRAGE boat, and show the dealer the drawing or other information in the owner's manual you mention, and inform the dealer that you have made a careful search of the boat in all possible compartments and locations, and...

Because boats are operated on the water and often have wet or very humid places in which electrical wiring and electrical connections are located, those electrical connections are prone to forming oxidation between the two metals of the electrical contacts.

Thanks for the update. To discover that in a 12-Volt power distribution wiring there is a connection that looks good but is actually not good is quite common, particularly on boats where water and oxidation are always likely to infiltrate a connection.

Also, [before committing to drilling the lower engine holes in the transom], I will also compare [the engine mounting height] to Tohatsu’s recommendation, which says the A-V plate for this engine should be 10-30 mm [sentence not completed, perhaps means 10 to 30-mm above the boat keel].

Q1: will raising the engine mounting height [from lowest possible to one-hole-up or two-holes up] improve the top speed performance of the boat? Yes, up to the point that raising the engine any farther causes reduction in cooling water flow or pressure and also creates a tendency for the propeller ...
