Q1: is the bolt head on top or bottom at the engine yoke [tiller]? To assess if the orientation of the bolt at the engine yoke or tiller will have an effect on the binding, try changing the orientation of the bold and then testing to see if the binding improves. I have a diagram of the steering gui...

I don't have any first-hand direct experience with either your engine or the battery you propose. But I am familiar with the electrical circuits involved. From the information on the NOCO website at https://no.co/nlp20 they seem to be quite confident in endorsing their battery for engine starting, p...

As a general rule, when you make a modification to a Boston Whaler boat, such as this big change in the seating that you are planning, a good approach is to make it possible to undo the modification in the future. I mention this because at some point you may want to sell the 130 SPORT and get a bigg...

I suggest that to create a really solid base for the new teak plank, use a board of the same width as the teak plank, and create a riser from the cockpit deck level to the desired new (lower) level for the teak plank to sit on. The riser board will transfer the load of the new plank, the new seats, ...

The published performance data from Boston Whaler generally is VERY representative of actual field test results, and being able to achieve the same speeds is expected. For a variation in maximum engine speed and boat speed from published data that is as much as you are indicating, that is, the engin...

Generally the BEST way to elicit advice is to ask a question. So far in this thread there are no question. If you happen to have a questions about Boston Whaler boats and want to elicit expert information, please start a new thread and ask your questions. In the future if you happen to buy a Boston ...

Q3: What do most people do with the sump? I have no idea what other owners of a classic MONTAUK 17 might do regarding the cockpit sump drain on a MONTAUK 17 or the use of a sump pump. Since you already have a sump pump installed, I would leave it there. If I had a MONTAUK 17 I would keep the cockpi...

I hope more installments of this illustrated narrative will be forthcoming.

You do not mention what metal was used in fabrication of the new tank. If aluminum was used you should mention the alloy. Coating aluminum with a corrosion-resistant sprayed-on paint is common. The color is usually green. Zinc-chromate was often used in the past. Today to find zinc-chromate paint at...

What is wrong with the original? You can probably clean that up to look like new in ten minutes.

Q2: is the bow eye fashioned from stainless steel?

Q3: was the left rod shorter in the original rod?

Q3: I will need to apply new bottom paint? Bottom paint is only needed if the boat will be kept in the water continuously for weeks and months. See the owner’s manual for advice on bottom painting. If you don’t have a printed copy of the owner’s manual, read my copy at https://continuouswave.com/wh...

Q2: am I correct that applying new gel coat will be the hardest task in the restoration? You are correct. Applying a new gel layer to the boat would be insanely difficult. Such a “restoration” for a c.1990 boat has probably NEVER been done, and it would NEVER be attempted by someone who was not fam...

Read this thread.

Q2: what is a ladder mount?

The stencil number 3A4950 identifies the hull as a 1971 16-foot hull. See the article in REFERENCE linked below. The model name MONTAUK was not used in 1971, so your 1971 hull could not have been sold by Boston Whaler as a MONTAUK model. To deduce what your boat may be will require seeing a photogra...

Generally when a very moderate V-hull boat is operating at speeds that produce an on-plane condition the forward part of the hull is lifted out of the water. For this reason the typical distribution of fixed weight and moveable weight is kept out of the forward end of the hull. Generally when on-pla...

Q1: should I re-foam the whole boat and fix the transom? Your notion of “re-foaming” the entire sealed and inaccessible interior of a 17-foot Unibond hull is unworkable. You would have to tear apart the hull and liner, essentially destroying all structural integrity of the hull. If the transom stru...

.“Bonding” seems to have a connotation of grounding. In DC circuits the term “bonding” refers to a circuit that is not intended to ever carry any current related to DC power distribution and is designed to connect together all metallic components of a particular system, such as the fuel system, in ...

Q1: is the wire insulation color coding in which the insulation color denotes the circuit as described in the REFERENCE article as used by Boston Whaler for direct current powered branch circuits typically used by other boat boat builders? Please note that in the article in the REFERENCE section th...

Q1: under what circumstances should an electrically powered sump pump be installed in a c.1986 MONTAUK 17? Read the advice in the owner's manual regarding drain plugs. If you don’t have a printed copy, you can use my on-line manual: https://continuouswave.com/whaler/reference/manual9-17/operations....

Q2: are you absolutely certain this boat has an Armstrong Braket? A typical larger Boston Whaler boat with an engine set back bracket would have a Whaler Drive, a completely different engine set back bracket than an Armstrong Bracket. A Whaler Drive is fiberglass and has a substantial buoyancy box t...

Look for a strap with a smaller load rating; the strength and size of the hook will proportionately smaller.

For a 13-footer a winch strap does not need a 5,000- or 10,000-lbs rating.

Q2: are the two waste pump-out ports provided on the head itself?

—or—

Q3: are there two separate fittings on the hull for connecting a marina pump-out hose?

ASIDE: if a 2015 boat is “too old” to receive factory tech support, Boston Whaler is losing its “legendary” company ethos.

Is there any space near the transom below the deck to fit a livewell pump or thru hull? Read this two-part article. There are many illustrations that will help you understand better. It shows a 22-foot hull, not an 18-footer. https://continuouswave.com/whaler/reference/outrageRestore.html Exactly w...

Q1: Is there enough room between the deck plate and fuel tank to run more hoses? Q2: is there enough room (in the bilge [under the cockpit deck] of a 1988 OUTRAGE 18] to fit in a live well pump and shutoff valve? The OUTRAGE 18 hull has no bilge. The space between the hull molded part and the hull ...

Repair the damage to the bow towing eye and to the transom lifting eyes before inverting the boat hull. You will need to fix those three fittings eventually, so do that job first.

Before attempting to invert the hull, you should consider removing the railings, the center console, and the engine. Employ several strong men to assist you. An overhead beam and ratchet lifts can be used to raise the hull. The bow eye and transom eyes can be used as points of attachment, if those f...

Note: if the embedded reinforcement by Boston Whaler is phenolic board, that material can be tapped, and machine screws can be used as the fasteners instead of self-tapping screws. I suggest you consult with the factory to confirm their preference.

Apparently the technicians at the marina either cannot read, are dyslexic, or never got your instructions. If you are not satisfied, you should work out a remedy with the marina. Without knowing how the retainer fasteners have been secured into the hull laminate in this installation, the integrity o...

The workmanship is excellent. To realize the most value you must find a buyer who wants exactly this sort of jazzed-up 13-footer. The typical buyer of a 1967 SPORT 13 won’t be willing to pay a big premium for all the additions. Most 13-footers are more basic, and are used by younger boaters, or as t...

The vacuum pump is also able to run automatically. It is powered by circuit 520-8, which also runs from the Starboard battery. A 10-Ampere circuit breaker (on Sheet 8) at the HEAD PANEL should shut off that pump via circuit 524-14 (Sheet 3) which runs into the holding tank area. On the drawing a rel...

The foam injected into the hull by Boston Whaler is NOT green. The foam is usually initially white and yellows with age. The laminating polyester resin or perhaps the fiberglass strands have a green hue.

Generally by 2010 and certainly in the case for larger boats like a 25-footer, the electrical wiring and control system was sufficiently extensive and complex that Boston Whaler would provide a detailed schematic diagram that reveals the exact wiring of all the electrical components, controls, circu...

The best view of the damage is seen in Figures 3 and 4. Here is a good close-up view: https://i.postimg.cc/gmgM0xgC/IMG-20250426-WA0004.jpg The damage goes past the gel coat layer, past the blue-green lamination layer, past the foam, and all the way to what looks like the woven mat layer of (the oth...

Q3: should this damage be repaired before any further use of the boat? Q4: does this damage require immediate repair? Damage of this type--keel rash--must be repaired. If you must continue to use the boat before making any repair, you should apply a high-quality high-adhesive-strength waterproof du...

Q2: [using the four types of damage as defined in the Boston Whaler factory repair instructions] what type of repair is needed for the keel damage as seen in Figure 1? Judging the damage to the hull from the photograph in Figure 1 is difficult due to the small image size, poor lighting, soft focus,...

Q1: how is damage to a Unibond hull repaired, such as seen in Figure 1 below? For advice on making repairs to the Unibond hull of your Boston Whaler boat, please read the article that is pinned at the top of the REPAIRS and MODIFICATIONS forum (i.e., this forum) at Advice on Repair of Unibond Hulls...

An accurate assessment will require seeing how the modification to become a center console was accomplished. The details and aesthetics will influence the boat value. Good photographs are needed. The SPORT 15 is a very popular model, and there should be very strong interest. The TOHATSU engine is an...

Q2: [in the manufacture of 13-foot hull by Boston Whaler] are there any bad years to avoid [due to defects in manufacturing] The only really notable problem in manufacturing of the Unibond hulls occurred in some larger models in which the hull sides tended to develop some waviness in what should ha...

Q1: other than a blue gel coat interior, what are the design difference between 13-foot hulls made prior to 1980 and those made after 1980? In the non-forum areas of the continuousWave website, particularly the WHALER section and its REFERENCE section, there are several articles on the 13-foot hull...

We are not sure how these boats are constructed. The essential feature of a Boston Whaler boat is its Unibond hull construction. This excerpt from the FAQ Q3 explains the method concisely: The construction of a Boston Whaler boat is based on the UniBond technique where two relatively thin uncured l...

Q3: what is your opinion on keeping the 1998 Anniversary Edition Super Sport [13] as original as possible? To keep the boat in its original condition is the best decision you could have made. But as seen in Figure 1, there are some parts missing from your boat: side console, railings, original anch...

I do not recall that Boston Whaler ever provided a center console version of the 13-foot hull. I suspect that might be because the beam of the hull was not sufficient to have a center console and still afford room to get around the center console. If you must have a center console, it would probably...

Q1: where is embedded wood reinforcement located in a 1991 13-foot hull into which wood screws could fasten a center console? For information about the location of embedded wood reinforcement in a c.1991 13-foot hull, please visit the WHALER section of the website, and then visit the REFERENCE sect...

Q2: can you identify ANY classic MONTAUK hull in which its original through hull drain was using plastic parts?
