I am buing a 1990 Boston Whaler 25 Walkaround WD. I am wondering which engines suit the boat? Can you help me?

Single Suzuki 300hp.

The 1990 Whaler 25 Walkaround is rated for 550 HP. I suggest a pair of Suzuki 300s ;-)

Oh...did not see the WD(Whaler drive) in his post so I thought max 300hp. So try a pair of 250 Suzukis.

It's not the Whaler Drive, it's the Whaler 25 not Revenge 25. Angelos has a "Wide Body" model. Think Whaler 27 with two feet cut off the stern. It is a MUCH bigger boat than the Revenge/Outrage 25 models. It is also rather rare and not well known.

Angelos -

Given your location, I would opt for a 225 or higher HP version of whatever engine maker has a strong dealer network near you.

If you are considering VERADO motors, take the time to find out who in your area is a certified technician, and how many VERADO motors they have sold and serviced.

Otherwise, I'd go with the strongest dealer in your area and check with local boaters (of any brand) to find out which dealership enjoys the best reputation for after-the-sale service.

Good luck.

OK, shooting from the hip here, but doesn't Sheila (on this forum) have a 25' Walk-Around with a single 225 or 250? Might look her up and get some input.

After re-reading my post above, I realized that I self-edited important information out.

I'd be looking for TWIN 225 hp and more engines....

I don't think you'll be happy with a single engine on this boat.

Sheila has a Revenge 25 Walk Around. Angelos has a Whaler 25 Walkaround. They are two completely different models.

As I recall, the Whaler 25 Walkaround (wide body model) was only offered in the Whaler Drive configuration. This is a very big boat, and one of my favorite models. I would suggest a pair of E-TEC 225s or 250's. Power and light weight will provide good performance on this big Whaler.
macfam posted 12-14-2007 08:50 PM ET (US)     Profile for macfam  Send Email to macfam     
Tom and andygere are giving great advice.
That 25 is a monster hull. Always one of my favorites.
There is a real nice one in Tashmoo on Martha's Vineyard.
Twin 225 2-stroke Yamahas
I bet two 225-250 E-TEC's would be awesome.
Four strokes would be heavier, but I bet that isn't an issue with that hull and W-Drive.
Hondas, Yamahas, Suzukis, or even Verados.

A 350 hp Yamaha V8 may not be enough.

I have the 27WA and twin 300 HPDIs are great. But the 27 has a 600 max HP. I would try twin E-Tecs 250 or twin 250 Vmax. What is the weight limit? That is what kept me from considering 4 strokes.

Here's an example of a Whaler 25 Walkaround that's berthed in my harbor.

This one is powered by a pair of Yamaha HDPI 200's, and the skipper posts on his website that the boat can do 50 mph. The owner (Jim Fuller) is a very knowledgeable guy when it comes to boats and Whalers, and he's also a nice guy. You may try to contact him via his website and see if he can shed some more light on the boat's performance.

Interesting aside: I ran into Jim at the launch ramp some months ago, and he was hauling the big Whaler to do some maintenance. He pulled it out with a Chevy Tahoe, and the Whaler just dwarfed the tow vehicle. This is one big boat!

I have twin 225s on my 27 Whaler WD. Twin 200s would be plenty for the 25 Walkaround WD (wide body). If I were repowering a 25 Walkaround WD, I would probably go with a pair of Evinrude E-TEC 200 HOs, then Optimax 200s, then Yamaha HPDI 200.

Although this has a WD, I would still be mindful of weight on the transom and try to keep it as light as possible.

Hi to everyone. I am impressed by your fast reaction and I would like to thank you very much. You can still see some pictures of the boat in looking for Boston Whaler 25 Walkaround WD 1990 Newport RI $30.000 or at google.

I do not know the weight limit. If someone can help me here it will be great. I also contacted Jim and I am expecting a reply. In Thessaloniki in Greece we have excellent dealers of every brand which I know most of them personally so this won't be a problem.

As I understood japanese morors seem to be more reliable. I am thinking of putting two four-strokes engines. I found a pair of 225 Verado of 2005 (new) and a pair of 250 Verado 2006 (new) in Florida at very good prices. My consideration is if it's better to go for twin 175 Suzuki four-strokes or twin 200 new L4 Mercury Verado? What do you think?

Perry posted 12-15-2007 12:03 PM ET (US)     Profile for Perry  Send Email to Perry     
I think that with a minimum HP rating of 300 HP, twin 175's would be a bit underpowered. The 200 Verado might be better, but it still is only a 4 cylinder motor. Since you are set on 4 stroke motors, why not get twin V6 Suzuki, Yamaha or Honda motors? The big Verado's might be a little heavy.
Peter posted 12-15-2007 12:28 PM ET (US)     Profile for Peter  Send Email to Peter     
Angelos -- That boat has a pair of Johnson 150s each of which weigh 400 lbs for a total of 800 lbs on the transom. A pair of 6 cylinder 225 or 250 Verados would weigh over 1,300 lbs, which is likely to be too much weight. I would be fearful that 1,300 lbs on the WD transom would cause the motors and the Whaler Drive to be buried underwater anytime the boat is stationary with the transom to a rolling sea of say 3 feet or so.

I would not go with the I4 200 Verado either simply because I think it would be greatly stressed running at cruise.

Ideally, this boat would do best with a pair of DFI 2-strokes. If it were mine, I would consider a pair of E-TEC 200 HOs or Optimax 200s simply because they provide the most natural displacement at the 200 HP level while keeping the weight increase over the 150s to a reasonable level.

Perry posted 12-15-2007 02:12 PM ET (US)     Profile for Perry  Send Email to Perry     
The boat currently has twin 150 Johnsons and the minimum HP and weight on the transom. Why worry about putting more weight than the miniimum it was designed for? This boat was designed to handle up to 550 HP.

I have not been on a Whaler 25 WD but I often fish on an Outrage 25 WD that has twin 225 Yamaha 4 strokes. It handles the weight just fine.

Captain Billy posted 12-16-2007 10:14 AM ET (US)     Profile for Captain Billy  Send Email to Captain Billy     
The weight limit is 1100 lbs for the 27WA. (per Whaler)
I think the problem with to much weight on the stern is the putting the scuppers under water.
JayR posted 12-16-2007 10:37 AM ET (US)     Profile for JayR  Send Email to JayR     
I think it would handle a couple hundred pounds over just fine.
If you are absolutely certain you will only consider 4 strokes, I think twin Verados would be very nice.

Being the happy owner of an E-TEC I would be remiss for not mentioning them. Weight would not be an issue and they are much nicer in color ;-)

I understood he was not here.
Suzuki, Honda and Yamaha would all be imports as well. The Veardos he is considering are in Florida.

Why would he not see a better return on his money buying a made in the USA product considering how weak the dollar is?

They are all going to be imported into Greece are they not?

We have Euros in Greece and US products are a bargain these days. Yes, I am also considering E-TECs. I have a 60hp E-TEC on a classic boston whaler of 1986 which I did a great and total unique job with mahon wood. I should send some pictures as the boat is one of a kind.

For the ease of docking and maneuvering I would sure want digital throttle and shift to go with my "twins"! My choice would be Gen II 225 Optimax DTS models!

Depends...what is import Duty in Greece? In Barbados it is almost 100% from the US. Not sure about importing from Japan. I was talking to a guy who bought a new OR 320 and it was about $275k delivered.

Finally, I decided to buy 2x175 Suzuki fourstrokes (2007) engines. Jim from California who has the same boat with hardtop and he was very helpful, told me that with 2 Yamaha 200 HPDI (2000) the boat was very fast (I esimate around 50 miles per hour) and he never missed a race back to port. He also mention that he wouldn't think to put an extra pount on the transom as with 3 people fishing in one of the corners of the boat, after a few seconds, around 2 inches of water is gathering in the back corner of the deck. The suzuki engenes are a little bit lighter than the yamaha ones (around 5 kgrs each). I bought them in Newport at a very good price and they are going to be put on the boat in US. The import tax from the US to Greece is 27%. I would like to thank you all for your comments. I will keep you inform of the results through summer. Happy New Year.

There is HUGE performance difference between a 4 cylinder 175 4-stroke non-supercharged, and a V-6 200 HPDI. I think the pair of Suzukis will be a costly mistake.

1. Whaler drive boats need a LOT more HP to perform satisfactorily, which is why BW gave them higher ratings.
Any WD boat will run 5 MPH slower than a notched transom model with same HP. They should be powered to close to max rating.

2. This boat is rated for 550 2-stroke HP, not 350 4-stroke HP. It may be a performance slug with anything but the lightest fuel and passenger load.

3. Never under power with non-supercharged 4-strokes, as acceleration and ability to plane under heavier loads will
suffer considerably. Go for full HP. The rec for twin 250 or 300 Suzukis was correct.

4. Most of the advice given here is correct, and apparently ignored, regardless of brand. It appears this Jim Fuller doesn't completely understand outboards in total, and unwittlingly mislead. The 175's may be cheap, but you get what you pay for.

5. My choice: a pair of 275 Verados, or a pair of DTS 250 Optimax! As said, that's one BIG boat.

Merry Christmas!

PSSS he said the same thing about me putting a 115 on my revenge and I LOVE it!

Don't get me wrong Larry but not everyone is interested in speed. In Greece gas is Gold so if he can run the way he wants..let him. I would love a 150/175 Suzuki on my 19 but honestly the way I would make very little difference exept when I put the hammer down and the cost is the key. How fast is your latest twin 70hp?...why not put twin 200's on it?

Angelos66 posted 07-27-2008 10:45 AM ET (US)     Profile for Angelos66  Send Email to Angelos66     
My first reactions so far. First, i have put a hardtop on the boat. The boat with the two Suzukis 175 4-stroke has a maximum spead of 42 mph with 4 people, a lot of year and 3/4 of gas. It goes to plane very fast without the use of flaps. The consuption with 4 people and gear is 2.2 litres per mile. It can go even less than 2.0 litres with less gas and gear. The cruising speed is from 27 to 31 mph. It cannot plane with a single engine. I have no problem at all with water coming inside the boat in any circumstances. I have the impression that someone can put havier engines without any major problem. I will come back with more info and pfotos.

djahncke that sounds like a great re-power. Maybe you can have your own thread for the re-power with some pictures.

Hey djahncke
I'm buying one in the next week hopefully, and most of them I've looked at could do with a re-power, hence my question (just getting my ducks in a row).
As far as propping it goes, what are you thinking for your E-tec 250? Would it change for a pair of Verado 225's or 250's?
I've had a fabulous last six years on a Verado 225, so I'm inclined to consider those based on my experience, regardless of the weight penalty, but I don't want to mess up either.
I've heard nothing but great things about the E-Tec's reliability.
martyn1075 posted 05-10-2014 11:49 AM ET (US)     Profile for martyn1075  Send Email to martyn1075     
Verado 200's would work and likely fit but any of the larger models you will need to modify the transom to accommodate the engines tilting up and out of the water. There is a large but attractive trim bumper that goes around the entire hull and it would need to be cut or removed. I'm not sure if that would even be enough I never bothered to try.

As noted, this thread began seven years ago.

Don's re-power must have its own thread. It will be completely distinct from and entirely different that what is being discussed here.

I do find suggestions based completely on speculation to always be interesting, not so much for what they might actually produce if someone followed the advice, but more as an indicator of the particular orthodoxy being used to give the advice.
