You will need to be careful when trying to drive out the tilt tube. When you do succeed, the engine will need to be in a stabilized position so it does not suddenly shift position. Your situation reminds me of an old joke: Q: How many therapists does it take to change a lightbulb? A: It only takes o...

Q1: What could cause the appearance of fuel in the below deck areas of a 2013 315 CONQUEST? Any element of the fuel system that is leaking fuel could cause the appearance of fuel in the below deck areas of any Boston Whaler boat with an internal, below-deck fuel tank. ASIDE: there are no bilge spac...

Because your existing engine is a 90-HP, and I suspect that engine was a V4, I would anticipate you will want to re-power with another 90-HP engine. I believe the specification weight for the V4 90-HP engine was 301-lbs. That weight would be a good number to keep in mind when looking at more modern ...

Regarding how the data in the REFERENCE articles that show information about the rated maximum horsepower was obtained, those data were always taken from published material by Boston Whaler. The concept that data about maximum horsepower rating would be collected by personally inspection the capacit...

I believe the damaged 17-foot hull has found a buyer.

FNO's comment is just about identical to what I was going to say.

There is an old saying:

Q: How do you wind up with a million dollars after being in the boat business for one year?

A: Start with two million dollars.

Q2: why did Boston Whaler change the maximum power rating? I doubt there is any way to know the motivation for changing the maximum power rating of the 15-foot hull to be 70-HP as shown in the 1984 catalogue from what appears to be a 75-HP rating on a capacity sticker for a boat said to be a 1976 m...

Maverick wrote:Perhaps the boat came from the factory with the 75HP rating sticker and Whaler changed the 1984 published rating to 70 HP.

That is exactly my inference.

Perhaps you are trying to say that when adding fuel to the 2004 DAUNTLESS 16 you get fuel splashing back at the fuel filler inlet fitting or you observe fuel splashing out at the fuel tank vent fitting. You then interpret this behavior as indicative of the fuel tank level being at FULL. Then when re...

Q1: what manufacturer makes high quality Yamaha-style fuel connectors (preferably made in the USA) that will not fail? Yamaha certainly must sell the appropriate fuel connector and it would be expected to be of suitable quality for use with a Yamaha engine, generally regarded as the highest quality...

The water line suggested location is shown in the owner's manual for most Boston Whaler boats In the owner's manual, read the MAINTENANCE section. Read under the heading BOTTOM PAINT. If you do not have a physical copy of the owner's manual, you can use my HTML copy that I published in the REFERENCE...

The data in the REFERENCE article notes it is from the 1984 catalogue. An excerpt from the 1984 catalogue is shown below in Figure 2. The rated capacity for the 15-foot hulls is 70-HP for the models that employ remote wheel steering. catalog1984SpecPage.png For Boston Whaler to change the capacity r...

The notion of buy low and sell high after some minor input of labor is not a particularly great approach. The first problem is to buy low. Q7: Have you looked at the prices for older Boston Whaler boats? Older Boston Whalers are probably about the most expensive "old" boats you can find fo...

Added third image ( see Figure 3 above) showing close-up of damage to the hull bottom. Figure 3 shows just how thin the hull laminate layer actually is. What is being seen is that a Boston Whaler boat is really a foam boat with a rather thin layer of laminates moulded around it. Once there is any se...

I've chosen to buy a Suzuki 25-HP... After you get the new engine installed and dialed-in with the proper propeller, let readers know the new top boat speed with the 25-HP. According to the Crouch Speed prediction formula, a decrease in power to 25-HP from 40-HP should cause the top boat speed to d...

Q4: would a 1983 Evinrude 40-HP short-shaft outboard engine that appears to be seized have any value for someone needing a short-shaft 40-HP and willing to rebuild it? My local Evinrude dealer--selling Evinrude engines for over 100-years--has a back room full of old engines that have some critical ...

Boston Whaler boats use the Unibond hull construction process, so they generally do not have stringers, at least not in the usual sense of that work in boat building.

Give me advice on how to assess used Evinrude FICHT 250-HP engines before buying them. The corporate owners of Evinrude have abandoned the outboard engine market. The FICHT engines have not been made in about two decades. The reliability of the FICHT engines varied with the production epoch. The la...

Q1: what other elements of a used Boston Whaler boat should be considered before purchase of the boat other than the several I already have mentioned? The most important element to assess prior to purchasing a used Boston Whaler boat is the hull integrity. Also, I have never heard of a buyer callin...

For six out of six stainless steel screws to "snap" seems very odd. There are only a few possible situations I can see in which this could happen. ⋅ the screws were of poor quality steel, had low corrosion resistance and low tensile strength; ⋅ the screws were over-tigh...

The forum is not the only portion of the website that has information about boats or about marine electronics. The section of the continousWave website that deals with Boston Whaler boats is located at https://continuouswave.com/whaler/ The section of the Boston Whaler boat area that contains long-f...

From what is shown in Figure 1 there appears to have been a proper grinding and tapering of the original laminate at the joint-line of the repair when the repair was made back in c.2008. You see this in the bluish area that is several inches wide on the perimeter of the repaired area. The almost rec...

Your explanation of how the de-lamination of a large section of the Unibond hull of your 17-foot Boston Whaler occurred sounds very plausible. Once the bond between the laminate and the embedded foam is broken, the hull strength is compromised. The flexing would certain tend to break down the bond o...

Your narrative is very surprising. Your 2018 boat is still covered by a ten-year hull warranty. You need to contact Boston Whaler customer service, and explain the problem to them, and also explain what appears to be no offer of help from the local Boston Whaler dealers. I don't think you should pro...

ASIDE: To hear you’ve been keeping that 1986 OUTRAGE 25 going is very good news. That hull is a really great design, the big-dog of trailerable classic-era Boston Whaler center consoles (and REVENGE models). The next step up in classic-era hulls was the 27-footer, which is much bigger, heavier, need...

To assess a gel coat color, the surface must be clean, must have oxidation removed, must be polished, and must be viewed in sunlight at midday. Having a sample of a pure titanium white color will provide a good reference for making a facile comparison between the hue of Desert Tan and a pure white.

I guess that using new gel coat to top-coat old gel coat meets the criterion that the product should not be AWLGRIP nor TotalBoat Wet Edge Topside Paint. However, I would expect that getting a perfectly uniform, defect free, and high-gloss finish with spraying new gel coat over the entire hull will ...

Fuel economy peaks at 4.1-MPG at 24-MPH. Your fuel economy data is very impressive. With 140-gallons of fuel tank capacity, your range at cruising speed would be about 550-miles. Even at 24-MPH that is underway for almost 23-hours, a very impressive endurance. That 140-gallon fuel tank was likely i...

I do not have any actual data that I myself have compiled about an OUTRAGE 25 with 250-HP or 300-HP, but I can make a prediction on the speed increase that will occur if your boat is re-powered with a 300-HP engine from its speeds with its current 250-HP engine. My prediction is based on the work of...

Seeing a photograph of the hull damage after the large section separated would be very interesting.

Q1: where was the damaged area located?

When the engine is operating and creating forward propulsion, water will be forced into the pitot tube. If the outlet of the pitot tube—usually a hose connection—is not sealed or is not connected to the pressure input port of a speedometer gauge, then the water is pushed upward and will be spilling ...

Those railings need the upper supports to be useful.

The fuel fill and vent hoses are usually on the Port side. The normal static trim of a Boston Whaler boat is to be with a slight list to Starboard. Rainwater on the deck should not be draining to Port and flowing into the fuel tank cavity in the channel where the fuel filler hose and the fuel tank v...

As I believe you are already aware, the modern, large Tohatsu engine manufacturing plant in Komagane, Nagano Prefecture, in Japan makes the engine Mercury sells. My recollection of the smaller four-stroke-power-cycle Tohatsu engines is that they have some sort of throttle body fuel injection and the...

Q1: having been used to a 40-HP engine on my 1973 13-footer, will re-powering with a 25-HP or a 30-HP engine make me happy? Assuming that the new 30-HP engine weighs as much as the original 40-HP engine, the effect will be reduced boat speed by a factor of about 0.86. This is based on the general t...

I infer that if you remove the Whaler Drive you want to put it back on. For a moment I thought otherwise. I can't offer any first-hand account of what might be encountered in trying to remove a Whaler Drive from the transom of a REVENGE 22 W-T Whaler Drive. At first glance, it looks to me to be a ra...
