Some, if not all Homelite - Bearcat outboards used Crosley engines. The long history of how Powell Crosley's 1940's engine became the 1970's Fisher-Pierce BEARCAT engine is described in rather good detail in the article already mentioned and linked above, which has been available for the past 23-ye...

Hey Jim, why don't you just kick me off your site, the way you have done in the past with others who disagree with your crap- You have made two errors in your question to me. FIrst, in the 30-years that I have been providing this website, I have only "kicked off" perhaps one or two people...

In 2001 I wrote an article on the BEARCAT engines. See https://continuouswave.com/whaler/reference/history/bearcat.html At the time I wrote that article, a fellow named Ed Ewing in California was refurbishing and selling BEARCAT engines, and he had hundreds of them. But he was already 80-years-old. ...

The above linked thread where Blackduck gives his anecdotal observations about the DF140 engine is actually quite strange, as it contains the admission of participant "Blackduck" that he joins any discussion about the DF140 engine to report how little actual horsepower he thinks it makes. ...

The support pole for the white all-round navigation lamp is intended to be installed and removed as needed. If the pole seems reluctant to come out of the socket, try spraying some WD40 as a lubricant around the bottom of the pole and let it drip into the socket. WD40 is safe to use on electrical co...

Hi Frank--this sounds like a nice project. The resources that participants here have access to for fabricating parts are always quite amazing to me.

As mentioned earlier in this thread, the best indicator of fuel efficiency for an internal combustion engine is the brake specific fuel consumption (BSFC). The best operating point for lowest BSFC is highly dependent on the engine design, the engine speed, and the load on the engine. There is no sim...

Note that this thread was discussing the strength of the transom on an older MONTAUK boat. There has been a new topic introduced regarding the fuel efficiency of two SUZUKI engines. That topic has been moved to its own thread in the PERFORMANCE forum. Please see Fuel Efficiency of Two Suzuki Engines...

115hp burned 3.6gph at 3500rpm 24.1mph 6.69mpg, range 133.. Top speed 47.8 90hp burned 2.1gph at 3500rpm 17.6mph 8.38mpg, range 166.. Top speed 41.9. That you have now provided some data to compare the 90-HP and 115-HP engine allows for an actual comparison to be made between these two Suzuki engin...

Q3: is the ONLY option to run electrical wiring to the engine splash well, then running wire to the port side? In the REFERENCE section article on the OUTRAGE V-20 , there is a good illustration that shows the rigging tunnel path, which I show below in Figure 1. https://continuouswave.com/whaler/re...

A corollary question: Q1: are you getting NMEA-2000 engine data on the ICON Pro RPM gauge, like engine speed and engine temperature?

The [140] engine is also shy of the claimed 140-HP. Top [boat speed] will be less than 40-MPH. A good 140-HP engine should push that boat to 44-MPH. Assuming the reported speeds are correct, we can then estimate the power of the Suzuki DF140 as something less than 140-HP based on its ability to onl...

Regarding renting a truck and then using it for towing a boat, my experience agrees with JEFECINCO's comments: most truck rental policies forbid using the rented truck to tow anything. ASIDE: when I bought a larger boat and did not have a tow vehicle that could tow it, I resorted to an age-old metho...

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 ...

Barbender wrote:I think the 2003 275 CONQUEST maximum power is specified as 450-HP.

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...

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...

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?
