So am I the only one surprised that Whaler made a diesel powered boat?
David Pendleton posted 07-28-2003 06:36 PM ET (US)
No. I've seen at least two of them on yachtworld.
I thought it was cool, too. I wonder about that engine, though. I don't know of any other boat that used it, Whaler or otherwise. I don't think Mercury even offers it anymore.
When I first saw one, I immediately thought of that awful gas-to-diesel conversion GM did with their 6-cyl engine back in the 80's. I think Oldsmobile was the only one to use it. Pure junk.
If I could replace the 5.7L in my Conquest with, say, a Cummins diesel, that would be perfect.

These MerCruiser Diesel Sterndrives are 4.2 liter Isuzu diesel engines marinized by Mercury; turbocharged and aftercooled, producing 225 hp @ 3800 rpm at the prop.
So few of these Conquests were made with this engine power option they should all be considered prototypes.
Still, at 39 large, it seems a bargain for someone looking for a safe, long range pocket cruiser.

I for one thinks its cool--never aware that BW did that. Wonder what type of performance, crusing speed et al. 100 gallons tank may be a little light, depnds on cruise speed.
Sure wish they had more photos though. Its a straight inboard ?

It exsist, I own one: 23 walkaround 1992 powered with Volvo - Penta AQAD 41 duoprop turbo diesel .- top speed about 355-35 knots
you can se photos of the boat at this link:

Fuel consumption is less than 35 liters of diesel per houer at 30 knots ,,,

Beautiful boat there petter5 and welcome to the forum!
I have seen similar larger Whalers in Holland also with Diesel engines.

Here's a 23-foot Conquest with a 4.2L 250-hp Mercruiser Diesel.
-Go to this link:
http://www.ewdriessen.nl/
-Then go to the "Occasions" menu and scroll down until you see the 23-foot Conquest with diesel engine. The specs and pictures are there.
I think you will find many Whalers with diesels in Europe just as you will find many more cars with diesels compared to the States.

Hi Merc_Fan !
You is wrong about the 4,2 liter mercruiser. It's not based on a Isuzu diesel. The engine is a Italian produced VM - diesel engine see:

It's a shame that they don't make this boat anymore, at least not for us Americans. With the price of gas these days, a diesel makes perfect sense, especially on a boat that size or larger. I'd be the first in line to buy a new 23' diesel powered, Boston Whaler Conquest.

That 23 Conquest in MA was for sale for about 3 years before they finally dropped the price so low that someone jumped on it.
I am sure we will see more diesel powered recreational boats on the water. I really like the new 300 HP Cummins Mercruiser diesel sterndrive:

Turbo diesel engines in boats abowe 22 feet is the future.
I recently replaced my old volvo penta 310 hp v-8 with a new mercruicer 4,2 liter turbo diesel ( bravo I ) and the boat was just like new. Top speed is excact the same, but owerall performance is mutch better. The best thing is the lov dieselfuel consumption. I don't have to spend so mutch time at the marina filling up with gasoline anymore, and I dont have to bring the same amount of fuel to go where I want. Where i before needed 100 galleons of gas to go, it's enough with 60 galleons of diesel,,,, :-)
