It has been just about a decade since Brunswick introduced their Mercury Marine VERADO outboard engine, and I have been waiting to see one used as a repower on a classic Boston Whaler boat. Thanks to the ingenuity of Miles T. from Lafayette, Louisianna, we have our first look at a Boston Whaler classic OUTRAGE 25 re-powered with a 300-HP VERADO. Miles, who is a professional engineer and a ship consultant, designed the set back bracket. The bracket is a 12-inch set back and (I think) adds three inches of height relative to the transom. Using a 15.25 x 19 RAMPAGE propeller, initial testing produced a boat speed of 49-MPH. Miles said the hull had a bit of wobble at that speed.

Miles has seen some transom flexing, perhaps not unexpected with the long set back bracket and the significant weight of the VERADO. Once the engine mounting height is dialed in, he plans to add reinforcement to the transom. He is looking for ideas on adding strength to the transom, and what it could be tied into on the hull. The transom notch will also be closed off to keep water from shipping aboard and perhaps also add strength

The white VERADO, which I think looks just great on the OUTRAGE, was a low-hour engine off a go-fast demonstrator boat with quad engines. In a bit of a mix-up, Miles ended up with a counter-rotating engine. The used engine, only 360-hours, was quite attractively priced, too.

Enjoy the pictures:

Splash well and bracket.

Rear view. The cowling top appears to be the tallest part of the boat.

How did he get a white Verado? I think it looks better than the standard Mercury black.

As I understand it, the boat builder of the demo boat had the quad VERADO engines custom painted white. I've seen several (pictures) of white VERADO engines. Last year there was a boat on the North arm of Lake Charlevoix, a monster center console--probably a 35-footer--with white VERADO engines. Yes, I think the white engine looks very nice, too.

Does that Verado have a 30 inch leg? White is not a slimming color but the advantage is it does not get hot in the Summer Sun.

Regarding custom painting of outboard motors:

Three years ago while anchored near Newport, RI on a sailboat cruise, I saw a go fast boat with triple Verados. The boat and the motors were painted a light mint green, similar to mint chocolate chip ice cream, or maybe Key Lime Pie.

That rig would have looked more at home in Florida. In fact it probably wintered there, along with its owner.

I was a bit surprised how natural the side view looks and how it sits in the water. It does not appear to be as heavy as I thought it might look. Saying that the rear view, well it doesn't look as natural anymore. That engine is huge.

The white looks nice, a bit weird to see a white mercury actually given the decades of jet black.

With that much power from a single engine on a relatively narrow beam boat, I wonder...does it list at WOT due to the twisting action of the prop? One of the benefits of Twin engines in a max hp configuration is the ability to negate that effect with counter-rotating propellers.

Just curious. I think this is actually the second Classic Whaler I've seen with a Verado repower. The first is Tom Birdsey's 18' Outrage up on Lake Champlain.

That engine is huge, but it doesn't appear to make the boat "squat" too much at rest.

Tom's OUTRAGE 18 has the four-cylinder VERADO. Miles's boat has the rather taller six-cylinder.

I agree with Martyn; the view in the first image gives a favorable perspective to the boat and engine. That classic 25-foot hull looks very low and long in that shot.

Jim it is interesting to see the engine raised up on the bracket. Seems to be as high as you could possibly get it as well. Does this mean if the engine was mounted on the original transom it would not work properly or at all? It it appears maybe at least 3inches if not 4 to 5? I'm more curious to find out why it's on a mount. If the owner is an engineer I'm sure there was perfectly good reason for it.

Reminds me of a sport 15 with a 90hp or even the one that had the 130hp v4 on his 15

That motor is a 30" shaft length model and the Outrage 25 takes a single 25" shaft length motor, hence the extreme high mounting.

Gotta say, the Verado looks a lot less goofy and massive in white.

It would look a lot better if it had the proper 25" engine instead of the that goofy 30".

I agree the hull handles the weight with no problem at all.

Overall I think the hull should be able to do more than 49mph, there was a 25 in the marketplace in Texas last year with a 300 Optimax and it was reported to do close to 55mph.

I agree. Given the engine height and propeller choice, I am sure some top speed has been left on the table.

This motor could easily be converted from a 30" XXL shaft length to a 25" XL shaft length by removing the Driveshaft Extension and swapping out the Driveshaft.

The Driveshaft is a $300 to $350 part and, presumably, the XXL Driveshaft and extension would have some value on the used market so some of the expenditure could be recouped.

The Boston Whaler OUTRAGE 25 can handle twin V6 outboard engines on its transom. The weight of older V6 engines would have been about 450-lbs each, so the total transom weight would have been at least 900-lbs. Since this single six-cylinder VERADO engine probably weighs about 750- to 800-lbs, it should not cause too much of a problem for the transom weight and for weight distribution. The static trim does not seem to be much affected, if at all. Of course, this is a single engine, and we are comparing to twin engines of old.

At the time the Outrage 25 was designed, a pair of 150 HP outboards put about 750 to 800 lbs on the transom. While it is difficult to ascertain with a great degree of precision, my observation is that the static trim looks about the same with the Verado 300 mounted on the short bracket as it would be with a pair of 150 HP 2-stroke outboards mounted directly to the transom.

Could always fab a wider bracket between transom and motor. It would relieve the force if its really a problem, mount with eight bolts. My Wahoo! 2600 had similar issue, when the new owner went from twin 200 mariners to a single F350 V8. A year + later no stress cracks. (He's my neighbor)

A 2 month old-news, but it seems Mecury will now offer two tone of white Verados right from the factory, available in spring 2014. Look like their "Warm Fusion" color could be a great match for the classic "Desert Tan"... mercury-introduces-white-300hp-verado-outboards/

Saumon--Many thanks for that news about the Mercury VERADO now being available in white, and in two shades of white to boot! I believe that Mercury will be joining Suzuki who recently introduced a white alternative color for their engines, and both will join Evinrude, who has been offering white or dark blue engines for some time. Evinrude also introduced a third color paint scheme, with gray tones recently.
