I installed the 47-Ohm resistor. I am glad you finally overcame your RESISTANCE to installing the RESISTOR. At this point, with the addition of the 47-Ohm resistor, the systems should be working. If I encountered this problem, my next step would be: --do a total reset on the ICON Pro RPM gauge, and...

Ratings for towing capacity are stated for an empty vehicle with only the driver in the vehicle. Any additional weight in the tow vehicle such as other people or gear must be subtracted from the rated capacity. The wheelbase length of the towing vehicle also influences the towing ride or feel, with ...

There is likely a strong correlation between the maximum power rating at 450-HP and the largest four-stroke-power-cycle engine sold by Mercury Marine being rated 225-HP in 2003.

That the SQUALL never made it back into the water is a sad twist to the long and interesting story.

The typical wiring scheme on a modern Boston Whaler boat, like a 2018 270 DAUNTLESS, will have an isolated feed from the main battery that remains on even when the main battery switch is set to the OFF position. This circuit is typically protected by a fuse or a circuit breaker, and provides power t...

Adding up the mentioned weights totals 1250 + 380 + 50 + 180 + 180 = 2040-lbs which is extraordinarily light. Adjusting the observed boat speed of 40-MPH speed over ground with favorable current of perhaps 4-MPH gives a speed through the water of 36-MPH. Using the Crouch speed prediction method, for...

Hello Jay. Welcome warmly to the forum and to all the other resources on the continuousWave website, which has been available since 1994, or for about 30-years. The website concentrates on collecting, organizing, and preserving useful information on its two principal subjects: classic era Boston Wha...

Whether the water accumulation in a cockpit sump with the sump drain left open to the sea will overflow the sump depends on the distribution of weight in the hull, and the particular hull. The speed that a pump can discharge a battery can vary with the control system. The traditional control system ...

The dealer stated “the 150 swings a considerably larger propeller, has considerably more torque, and would increase the boat speed at full throttle by 8-MPH [compared to the 140-HP engine] Any increase in power is offset by the increase in weight. Boat speed increase only with the power-to-weight r...

Leaning against an elevated base mounted on a gunwale for a down-rigger sounds extremely uncomfortable.

Q3: where can railings like those [unclear] that will fit on an [unspecified model year and now maybe 50-year-old] OUTRAGE V-20 be purchased? If you asking about a railing as illustrated in the linked reference article (above) that is an off-the-shelf exact duplicate of the aft cockpit athwartship ...

I think the model designation 48SPL—if that was the actual original model—might not have used the VRO mixing pump.

To predict speed use the Crouch Method. I have implemented the Crouch Method in a calculator, the Crouch’s Calculator. For power use 115-HP For hull factor use 180. For weight, you must add up all the weight on the boat. For a wild guess I will use 3,000-lbs. The calculated target boat speed is then...

Give me guidance on propeller selection. The propeller should be a steel three-bladed propeller of proper hub diameter to fit the engine gear case. The propeller blade diameter must fit the propeller aperture available on the engine. The propeller pitch must be a suitable load for the engine to all...

Give me guidance on engine mounting height. My own research indicates the Anti-Ventilation plate [should be even with the ] bottom of the boat. Instruct the dealer to install the engine with the engine mounting height one-hole (0.75-inches) up from lowest position. Whether or not the engine mountin...

The boat looks quite nice, but an older two-stroke-power-cycle engine with multiple carburetors that has not been used for ten years is really an unknown quantity. At best, it runs like a 33-year-old two-stroke that smokes a little and burns more fuel than a modern engine. At worst it won’t run at a...

For a quick sale, your asking price should be $10,000. If you are not in a rush, wait for Spring, have the boat available for a sea trial, and start with a much higher price. If the engine runs well and the boat shows well, it could sell for more. To facilitate a sale, set an asking price and re-pos...

Are you considering buying this boat or selling this boat?

Regarding performance, 115-HP is 115-HP, so the boat top speed should be the same. The E-TEC direct-injection two-stroke-power-cycle engine might have had a wider engine speed range at which it could produce its rated power that a typical four-stroke-power-cycle engine of the same displacement, so a...

The bank assessment is well below fair market value. Based only on your assessment of the condition as practically like new and practically no engine run time, this freshwater 2010 170 MONTAUK could fetch as much as $35,000 if the seller is able to wait for an offer that high. At the bank’s valuatio...

I’m trying to follow them but I don’t understand wiring in the resister when I’m using the Nema [sic] source not the analog source. I have already pointed you to the answer to your question. It does no use to give you pointers to the answer to your question if you do not follow the pointer to the a...

Please indicate the Southco part you will use to create the key-lock latch.

You should feel free to not follow the advice already offered to remedy the problem. I have exhausted all my ideas and attempts to explain them.

The worst of the three suggested methods is to discard the existing console and try to get a different console from Boston Whaler. First, I doubt you could just order a blank, unfinished console. Second, you’d have a Frankenstein 170 MONTAUK, with probably reduced value unless the work was done to t...

Q1: How can accumulation of rain water in the cockpit of a [unspecified model year] MONTAUK 17 be prevented while moored and unattented? See the owner’s manual for advice. If you do not have a printed copy of the owner’s manual, read my on-line HTML version at https://continuouswave.com/whaler/refe...

The horsepower plays no part in my recommendation. When you buy a new engine to re-power a 36-year-old boat, the important elements to consider are: ⋅ is the dealer familiar with selling loose engines and rigging them on 36-year-old BOSTON WHALER boats? ⋅ is your boat electrical ...

From your narrative this boat has already had three engines, a 40-HP, a 50-HP, and a 90-HP.

Q3: Why do you now think that buying a new 90-HP engine would be over-powering the boat?

I need to understand this before I can offer a recommendation for a new 90-HP?

Hello Keith. You can read about you new Boston Whaler 2006 170 MONTAUK boat in the REFERENCE section of the website. Here is a link to the article on the initial version 170 MONTAUK: https://continuouswave.com/whaler/reference/170Montauk/ Another good article on the early 170 MONTAUK can be found in...

I don’t think the BX cable sheath had electrical conductors in it. There typically was a flat two-conductor zip-cord type cable that was run to the bow and concealed under the rub rail, but I don’t know for sure if really old 13-foot hulls would have that, as those hulls tended to have a one-piece w...

The propeller ventilation is probably due to too much weight shifted to the bow causing the boat trim to be unusually raised in the stern. Repeating earlier question: what was the original Boston Whaler model designation for this hull? Repeating earlier request: please describe engine mounting heigh...

Q1: what is “bully net boat design”?

Q2: what was the original model designation?

[No additional engine speed can be used without] spinning propeller.

Q3: what is meant by “spinning propeller”? The propeller must always be spinning in order to produce thrust to propel the boat.

Q2: what new engine would be a good choice? Because you will pay for the engine, not me, I recommend getting a modern four-stroke-power-cycle engine with electronic shift and throttle, the new electronic remote controls, the OEM best digital gauges, a new stainless steel propeller, and replacing al...

Q1: is 250-HP too much power for the [1984 OUTRAGE V-20] boat? Yes. Q3: what will be the change in fuel efficiency with a new engine? Typically the overall fuel consumption will decrease to about half the former consumption. Modern engines are very much more fuel efficient at idle or low power sett...

Your analysis that the source of the rust is from a metallic spiral electric cable is correct. Boston Whaler used BX-cable in the early 13-foot boats. I don’t know the precise reason for the use of the steel-sheathed cable, but I believe the spiral metal sheathing had something to do with venting ai...

Any non-metal fuel tank would typically be made in a mold, so the chances that someone has invested the enormous costs necessary (to create a mold for a particular fuel tank space on a 1981 OUTRAGE 24 in order to create non-metal replacement fuel tanks) are extraordinarily small or perhaps zero. The...

In some instances a very good method to discover the original hue and luster of the gel coat layer on an older Boston Whaler boat may exist if there is a fitting that covers a portion of the gel coat and there was a very good seal between the fitting and the hull. An example of this is seen below in...

You should get answers to those questions about what SPECTRUM is willing to do for you from SPECTRUM. My guess is that if you want SPECTRUM to create a special order of gel coat resin to match your boat, you probably will have to pay more than the $53 they charge for one of their off-the-shelf color...

Q1: what solvents can dilute and remove residue and stains created by "grip tape" from non-skid gel coat areas? If you still have the "grip tape" you should test various solvents on the tape itself, before putting them on the gel coat. You might be doing more harm to the gel coa...

ASIDE Thanks for the update on the spark and using the same tester as Jim mentioned. In my 40 years of engine work, I've never used a tester and rely on a spark plug with the metal body touching the engine block. The very significant advantage of investing in the under-$20 LISLE spark tester is that...

From the mention of CARB, I infer you are in California. You should be able to buy pure gasoline as aviation fuel. You might check with a local small airport fixed base operator to see if you could buy a few gallons of aviation fuel as a test. Your new observation that you are now able to observe th...

The first step in assessing the color of the gel coat is to restore a portion of it to its original hue and luster. Typically older gel coat finishes that have been neglected will have oxidized and lost their luster. Use very fine grit emery cloth, maybe 600 grit or higher, and lightly wet sand a po...

The fiberglass is in good shape, but the hull has some bumps in the gel coat at and below the waterline. Q1: should I refinish the hull with new gel coat? Q2: or, should I give up on the gel coat and just paint the hull? If most of the original gel coat layer on the hull is "in good shape"...

Q3: where did the yellow debris seen in Figure 3 come from? My first thought was to ask you if while you were working on the carburetor were you eating potato chips? More seriously, speculating on the source of the yellow debris (discovered in the carburetor bowl from cylinder-2 of the HONDA BF25 e...

I bought the LISLE in-line spark tester. The number-2 cylinder seemed to have strong and [continual] spark...The HONDA BF25 still ran exactly the same as before. I am inferring that what you are reporting was a test situation where after the engine temperature rose to the normal hot engine range an...

ASIDE ON NEW TOPIC OF RE-POWERING
I had a 1976 SPORT 15 with a 50-HP engine. It was very fun to drive. With 30-HP I don't think the boat would be nearly as fun to operate.
