Owners with the classic 15 Super Sport with a Mercury 60 FourStroke with the 1.83 lower unit, the recommended prop includes:

13 3/8 x 12 Vengeance

The engine should be mounted 1 hole up meaning the top engine bolts are in the second hole down from the top.

Phil T

Ed--welcome back. Here is a simple answer for the propeller: For the Montauk 17 with the classic Yamaha 115 2-stroke the ideal prop is the 13x19 Yamaha Painted Stainless Steel. For mounting, you want to make sure the anti-ventilation plate-- just above the propeller--is 1-1/2 to 2-inches above the b...

Phil T

Please correct the model name.

There is no such model as a 28 Whaler.

Phil T

I take it you are outside the US, possibly in the Netherlands based on the registration? Given how rare a Outrage 25 is, consider asking the dealer to remove one engine, remount and remove the bottom paint on the transom. You could do it yourself but research what selling the extra motor would get y...

Phil T

It would help to know the name of the dealer for others to be aware of. That is shameful. Most likely he is deflecting from the news there is a several month wait for a motor as demand has outstripped production of many models across the brands. https://yamahaoutboards.com/en-us/find-a-dealer

Phil T

While there are a few companies that will insure a boat with horsepower above the capacity plate, this candidate is excessive.

Is the boat for sale by an owner or broker-dealer?

Have you seen it in person?

Are there photos?

Are we sure it is not an Boston Whaler Guardian 27?

Phil T

Irrespective of whether or not it has a re-enforced transom, there is no practical reason to have this much weight on the transom. The factory will not install engines that exceed the capacity plate. A Guardian 25 could come with a "reinforced" transom. I would be highly concerned of the l...

Welcome to CW. I would contact the Whaler Parts Guru, Sue Lodel, Parts Manager at Twin Cities Marine. http://www.beacontcm.com to see if she can get you just the pole. If no joy, I would contact Raymond Martin at http://www.martinmarinedesign.com and ask him to fabricate the pole for you. He does Wh...

The part # have changed over the years.

From the thread -

"The Whaler part# for the blank panel with switches is 1848341".

Phil T

In looking around, I see Jay Heiii's 2007 Montauk 170 has the same exact panel.

See: http://continuouswave.com/forum/viewtopic.php?f=6&t=3981&p=22558

Phil T

While not exactly what you are thinking, consider this. You can use the existing panel and cover it with 3M Vinyl. Replace the switch "covers" with labels. Several owners have "refreshed" their panel without spending the $$. New Wire Marine sells switches and covers at reasonable...

I did a little research on Whaler's Resources page of their website. For 2005, Montauk 170 there are two instrument panels shown: Screen Shot 2021-04-11 at 1.35.23 PM.jpg There are parts # 09 and #63, described as: partListTableExerpt.png Note: There have been many Montauk owners who have ordered ne...

It is not integral and can be removed.

Phil T

Ice out was early this year. Good for you.

Phil T

I would reach out to Ken or Dan.

Phil T

It is clear you are not on the right path.

Also, the engine should be mounted two- or three-holes up, top bolt in the third or fourth hole down from the top. This is why you are porpoising.

I recommend you go back and read my prior post.

Phil T

Instead of a two step hoist I described above, consider going with a spreader bar type setup. From each hoist would be two straps/wire cable to a spreader bar the legnth necessary to span the beam of the boat. From the each spreader bar a strap (with small weights) would fall from the end, down and ...

Phil T

Tony--my suggestion comes from watching the RNLI in the UK. They retrieve their Severn/Trent class rescue boats (14'm LOA, 28 tonne) by winching them up a long steep ramp via cable, then change to an industrial strap harness for the distance into a boat house. The strap is what keeps them secure.

I reached out to Don offline and he provided the factory instructions.

While it is a .pdf I saved it as a jpeg so it can be uploaded here.

Phil T

When I ran the numbers I got 18" of pitch. This is based on WOT of 6200, Target speed of 56, slip of 5% and gear ratio of 1.83

I presume Scott is trimming the engine out.

Phil T

Here are the pages from the manual. Screen Shot 2021-04-07 at 9.31.50 PM.jpeg Personally I would lift the boat with wire cables then position wide lifting straps slightly forward of the transom and a second aft of the bow and support the hull that way. The straps would be set at a fixed height and t...

The CGP or BCPD boat market is challenging, even in good times. The Frontier, based on the Outrage 25 hull is smaller, lighter than the Challenger or Guardian 27. As for navigating between Miami to Nassau, Bahamas, the distance is 185-miles. For any boat, it is a matter of sea conditions, engines, a...

Phil T

I think you have the wrong version.

The flat annode is for twins or engines with hydraulic steering.

Call Andy at SIM Yamaha. They will get you sorted.

If you can't get in the boat, even take it for a sea trial (weather is now nice). FORGET IT.

Would you spend $24,00 on a car you can't see in-person, get in and go for a test drive?

Phil T

Having done an inspection of two Challenger 27 boat, I am very smitten. Then again, it depends how you are going to use the boat. For cruising year round in the upper NW, Alaska or DownEast --> Challenger. For fishing, diving, freight, etc ---> Frontier. Demand is through the roof, the prices are ri...

Phil T

Scott--with the Enertia, the engine is 400-RPM under WOT 6200-RPM. I would say drop pitch by 2-inches. You may gain you another 2 to 3-MPH. Then again... Can the engine mounting go up a hole? Typically Mercury engine can go up one-hole higher than typical due to their midsection (per LHG), and hhenc...

Phil T

Propeller performance is not all about size. You need to take into account the make and the model of the propeller. From experience, a Montauk 17 with a 115-HP engine running light and mounted three-holes-up should be able to reach 49-MPH. What model year is the Mercury 115 Pro XS? The early version...

One should not compare a 2011 Montauk 170 II (taller console version) to a Montauk 170 III (completely redesigned hull, interior fuel tank etc). Comparing apples to bulldozers.

If you are concerned about the prop, just buy a cage.

Keel Guard or similar products are added to the keel only rather than the chines. Most installations go five to six feet aft of the bow eye. Typically this is all that is necessary to beach a boat. When beaching my boat on the precast concrete planks covered in barnacles at the local boat ramp with ...

Look for these sizes

13.25x15 PowerTech SCP
13.25x15 Yamaha Performance Series
13.25x15 Turbo 1
13x17 Yamaha Painted Stainless Steel

This is the results from the prop size calculator.

Jack--sorry to surprise you but this is one of the worst times to repower. Due to COVID, demand for boats and new engines is off the charts. Boat production is already sold out for this year and part of next. Many owners expecting to just walk in and buy a new engine to re-power are waiting until fa...

All the marinas I have visited in New England use floats of varying construction. They support boats in size from 15' to 250' super yachts (have a helicopter on the upper deck and/or tender inside the fantail). As for decking, if boards are required, composite materials. Other materials include stam...

Phil T

I find it highly surprising the new docks are fixed rather than floating. Given the variable level of the lake, it would, to me, be prudent to take this into account in the design. A future period of higher water levels will result in repeating the same damage as before. Steel piles and concrete flo...

Phil T

Please STOP confusing the hole location with the actual position of the motor. The motor position should NOT be taken into account. Get a measuring tape and MEASURE the holes. Look at the DIAGRAM with the distances and then measure to the locate the lower hole location. Mark it, then drill. If it is...

Phil T

You don't drill the holes to a fixed height. You drill the holes so that the engine can be adjusted in the future. Look at the diagram in the reference section. You are over thinking this. We recommend mounting the engine (not drilling) 2 holes up (bottom bolts in the slots), top bolt in the 3rd hol...

You can simulate the change of engine weight by adding bags of gravel or sand to the splashwell. As for performance, you will probably have to change props with the engine change. Before I spend any money I would review your boat's current engine setup and rigging. I have a sense there are adjustmen...

Phil T

You may want to wipe down the rubrail insert with Acetone to see if it will come back.

Splash boards should have two rectangular openings with hinged flap that only swings toward the stern.

Rough dimensions for an appropriate opening would be 4" high x 11" wide.
