Lupi, while your engine is much newer than mine, has a different gear ratio and almost certainly a different torque curve, you might consider the Trophy Plus prop. I did a comparison of several props on my 160 Dauntless some years ago, see http://continuouswave.com/ubb/Forum4/HTML/004868.html , and ...

I replace my impeller every 3 years. I mostly boat on deep fresh water, and the old ones come out looking brand new. But considering the consequences of impeller failure, it seems like cheap and easy insurance. For the same reason, I buy brand-name parts. Frequent replacement also ensures that the l...

I'm sorry for what you had to go through, but the repair looks like nice work.

Eagle1499, I've now had a chance to put about 25 hours on my 160 Dauntless since installing the Lenco 4x12" trim tabs. The results are fabulous! See my writeup at http://continuouswave.com/forum/viewtopic.php?f=6&t=3860. This upgrade was well worth the cost and effort!

Every boat design is a compromise. For the 160 Dauntless, the designers gave a small boat a lot of beam, a huge 45 gallon internal fuel tank, and lots of storage space. The trade-off was that the boat is heavy for its size. Add to that the fact that the boat was designed in the waning days of 2-stro...

Hi Brian, I apologize for the long delay as I was on vacation without internet. The foil has already found a new home, sorry.

I've replaced the throttle and shift cables on my 160 Dauntless. Because they are not very flexible, I'd suggest pulling out the old cables and pulling through a messenger line, then using the messenger line to pull through the new cables. Maybe pull through another messenger line so you have one fo...

This SE Sport 200 hydrofoil has been on my 160 Dauntless for almost 15 years; now replaced by trim tabs. It is showing its age, but as best I can tell is not broken or cracked in any way. Yours for the actual cost of shipping, tell me your zip and I'll tell you the cost.

Yes, I saw the thread about the Nantucket transom , and it led me to give my through-hulls a good inspection. Both the motor well drains were loose, as was the bilge drain. One of the cockpit drain transom fittings was loose and cracked at the base (great recipe for a sinking if it wasn't a Whaler) ...

Now it's on my "almost done" list. I'll let you all know in a week or two how well they work.

Chuck at Boston Whaler [is quoted elsewhere that] the replacement part is Hi Tide Manufacturing part #2301603, and that Sue at Twin Cities Marine can procure them.

On larger boats, this is pretty typical. The bottom gets a few coats of bottom paint with the boat on stands, then when the boat's ready to launch they lift it in the TravelLift straps, slap a quick coat of paint where the stands were, and launch--often just a few minutes later. It's pretty clear wh...

I have one very much like what Phil showed from West Marine. Might even be the same thing, I don't remember where I got it from. In any event, it works great and is very easy to use.

This thread scared the hell out of me, so I went and inspected all the through-hulls on my 2003 160 Dauntless. The large cockpit drains were fine and the bilge pump outlet seems fine The large cockpit drains were definitely NOT fine. Both of the L-flange fittings at the back of the cockpit were loo...

There's not a lot of room in the rigging tunnel, so I'd go with approach (a) because the plug at the console end is smaller than the transducer.

Hi Henry! Looks like you're talking about part #9 in this drawing: Nantucket deck plate.png That's a Viking PTL-10 deck plate . Unfortunately, this kayaking site says that Viking is out of business and all parts are discontinued. I found a few parts listed online, but all showed "out of stock&q...

I recently replaced a SONAR transducer, and of course the new mounting holes did not line up with the old mounting holes. I cut a small rectangle from some leftover KING Starboard, mounted it to the hull using the old mounting holes and some 3M 4200, then drilled the Starboard for the new mounting h...

Even if the plastic through hulls are okay, I would consider removing them, coating the hole in epoxy and then re-installing the hardware with marine sealant.. Yes, that's certainly a good idea even for the "good" through-hulls. Really, the quality of these boats, while perhaps imperfect,...

I'm looking at the Mercury website, at the 115-150 four strokes , and the photo on the web page does not show a trim tab. So I pulled down the brochure linked from that page, and sure enough, most of the engines in the brochure don't show trim tabs either. Only the 25-60 hp four strokes have a trim ...

Installing Hydraulic Steering by Bob Kurtz My 2003 Boston Whaler 160 Dauntless came from the factory with Teleflex No Feedback cable steering with a tilt-helm. This system prevents the wheel from turning due to engine forces; the wheel simply stays wherever you put it. Although it had an odd dead s...

A few years ago I replaced the Teleflex no-feedback cable steering in my 2003 160 Dauntless with the Baystar hydraulic system. The installation was in fact pretty straightforward, and the results are great -- possibly the best upgrade I've made to the boat. I bought the kit with the tilt helm, which...

I've always assumed that these demo boats are chosen for this fate because they have foam voids or other QC defects that make them unsaleable. But if you're looking to return this boat to regular duty, I suspect foam voids are the least of your worries.

and while there are other brands, someone else will have to make suggestions on them But since nobody has yet done so, a little web research suggests the following possibilities: Evinrude/BRP Rogue 13.25 x 15 Yamaha Talon SS4 (can't easily find available sizes online) PowerTech NRS4 13.25 x 15 One ...

I wouldn't say that the seller "pulled a fast one", but the boat is certainly under-powered. Plugging my data into the speed calculator at http://www.go-fast.com/boat_speed_predictions.htm (2600 pounds, 115 hp, 42 mph, getting a hull constant of 200) and then substituting your engine at 75...

GoldenDaze

I don't mean to sound too negative, but I have serious doubts that you will ever get adequate performance out of a 75 HP engine on that boat. You are right in all respects, the 160 Dauntless is a heavy boat for its size, and it is somewhat stern-heavy. Even with my 115 4-stroke, my 160 Dauntless (20...

I have a 2003 model with a Mercury 115 4-stroke. I added a foil a long time ago, and it certainly helped a lot. But I've never been completely happy with it, since trimming the engine all the way down induces a lot of steering torque (that is, the wheel is easy to turn one way but hard to turn the o...

Letters on my 160 Dauntless are 5" high. If I had to do it over again, I'd have used a different font. But at least I didn't use Comic Sans.

From the Washington Post: "The Navy built a ‘fast, agile’ warship for $440M. It’s been stuck in ice since Christmas Eve."

As Jim said, knowing what the propeller is will tell us a lot. My 2003 160 Dauntless with its Mercury 115 4-stroke will run at 43 mph with a 4-blade 17" Trophy Plus prop, but when I put on a 13" 3-blade aluminum Black Max I get a maximum speed right about 35 mph. It's great for pulling up ...

That makes for sad reading.

14 years later, the Mills cover for my 160 Dauntless is still going strong. And I seem to recall that I paid a little under $1000 THEN, so this seems like the deal of the century.

Every 15 years I replace my electronics, whether they need it or not. ;-) My Garmin FishFinder 90 has been swapped out for something newer, but it's still fully-functional (for what it is, of course) and willing to work well into its retirement years.

Hi Ralph, your speeds look about 2-3 MPH lower than mine across the whole RPM range. To me, that suggests that your prop pitch is a little low, and indeed it is a bit lower than mine. I'm a little surprised that you aren't hitting more than 6100 RPM at wide open throttle. That said, overall your per...

Earlier you asked about engine mounting height. My boat was delivered with the engine mounted all the way down on the transom [lowest possible position]. I first raised the engine by two holes [to two-holes-up], but found that while life was great in a straight line, the propeller would ventilate in...

The 170 Dauntless is a really nice boat. Everything I like about my 160 Dauntless, they kept or made better. The few things I don't like about my 160, they fixed. What's not to love? That said, the 190 Nantucket-Outrage is more boat in every respect: performance with a 150 will be excellent; the boa...

Just to verify, there are under-deck reinforcement panels (#42, 5"x12"x3/8") that might be suitable for the forward legs of a T-top, but no suitable deck reinforcement for the aft legs. They would have to attach to the console or use the toggle-bolt approach mentioned above. 160DA rei...

Hang in there a while longer and maybe I'll have a deal for you. Trying to build spousal support for a bigger boat. :-)

GoldenDaze

I'd have to agree. While the 160 has a little more space on either side of the center console than a classic Montauk 17, I think a t-top mount would be a tight fit and would be hard to get around. As for weight, I was out yesterday on the Chesapeake running down and across 2' whitecaps and would not...

I went back through your prior posts, but I can't find anywhere where you've said whether you have the 90 2-stroke or the 90 4-stroke (or specifically what propeller you have). In 2001 the 90 4-stroke was a carburetor-fed engine, and a little searching (particularly in the old forum) will turn up a ...

I agree that your top speed seems unusually low. My 2003 Dauntless 160 will make about 42-43 mph with its original Mercury 115 4-stroke using a 4-blade 17" Trophy Plus. Top speed with the original prop, a 16" 3-blade Vengeance, was about 2 mph higher but its acceleration was relatively poo...

I realize that yours is a pretty small boat, but you might consider replacing the whole steering system with a BayStar hydraulic system. I made the switch two years ago on my 160 Dauntless and it has really been very nice.

I could go on and on about the Dauntless 16, having just finished up my 13th season with mine. Although it is only a foot longer than the Dauntless 15, if you look at them side-by-side the 16 is huge in comparison. It is extremely capable for a 16 footer, and I've had mine out in as much as 4-5 foot...

Great description of how conditions vary. If the wave crests are below the gunwale on my 160 Dauntless, that's less than two feet. Three feet is when the crests look about chest high when I'm in a trough. At five feet the crests are pushing up to the horizon. I've had that happen once on the Chesape...

Oh, and since I know this is a new boat for you, let me share that the best change I ever made to my boat was to add a lower unit hydrofoil (though if I were to do it again I think I'd bite the bullet and put on the 4" Lenco trim tabs instead). The second best change was to change from the orig...
