Is 1998 [through] 2001 Conquest [21?] and current 210 Ventura same hull design? The rear cockpit and rear folding bench seat are identical.

What is the maximum transom weight for 1998 through 2001 Conquest that supports twin 150 HP engines? The current [235 CONQUEST] only supports single engine and has poor rear seat design.

The 235 CONQUEST and its transom configuration which does not permit twin engine powering is reflective of a general trend in outboard boat powering in which the twin 150-HP set up has been falling from favor. This topic was discussed in a prior discussion. See

Twin 150-HP: A Thing of the Past

Also affecting the design of Boston Whaler boats is their commitment to using only the Verado FOURSTROKE motor. Twin Verado 150-HP motors will weigh well over 1,000-lbs. That is an enormous amount of weight to hang on the transom of a 23-foot boat.

Feel free to pursue the dual engine set-up. As the owner of a Conquest 235 I feel that the single engine provides better fuel economy,lower maintenance costs and a substantially lower purchase price. The Verados are proving to be a very reliable motor. The generation II Verado offers lower fuel burn rate in the upper third of the power band. I am a Great Lakes salmon troller primarliy. Having a quiet, fume free propulsion system that allows normal conversation to proceed over the hours spent tending rods and playing and landing fish is a true, bonified benefit!

My wife love the rear seat set-up. I love the cockpit space the fold down option provides.

I spent seven years working in fisheries research on the Great Lakes, spending hundreds of hours in three classic BW hulls(two Outrages,one Montauk) during nearly every sea condition imaginable. I also own a 1995 Outrage 21'. The Conquest 235 is flat-out a better rideing boat, with lines very pleasing to the eye as well.

If you go with the older Conquest 21, take a test ride in a head sea. I think you will get your answer on why the hull redisign occured. Also, take the boat out ina following sea and get up on the crest of a wave-throttle up a little, and surf down the face of wave into the trough.
Note how the boat resonds. Get a two-hand grip on the wheel before you hit the trough with the bow!

I think the rear seat design in the 235 CONQUEST is patented, and I believe it might have won some sort of design innovation award.

I have a 235 and have to agree with Thirsty Whaler on the fuel economy and maintenance costs. I fish with a number of guys that own boats and they are amazed at how little fuel we use. For example, when I troll at 3.5 mph I only use 0.7 gph. When we split expenses I am known as a cheap date.

Because we trailer our boat, often long distances, yet we enjoy sleeping aboard overnight, the 235 CONQUEST is the perfect solution. The other CONQUEST boats are too big to easily trailer, and due to their width could be difficult to legally tow on most state roads.

Back to Steve's original owner of a 1999 Conquest 21, I can confirm it is the same hull as the current 210 Ventura.

The rear seating arrangements are different however. The folding rear bench seat is not on the Conquest 21. It has two stern quarter seats. I believe the Conquest 23 had a folding rear bench seat option, with the extra two feet of aft cockpit space.

The Conquest 21 was designed for single engine, up to 250HP. Most commonly equipped with 200 or 225HP. The Conquest 23 was rated for twin 135s.

These transoms can handle the extra weight of a Verado 225HP, which makes them attractive for repower in a few more years. Based on Seabob's latest DTS/Smartcraft post, I think I will wait a few more years for Mercury to work the bugs out of the software.

Mambo can get the Honda now and you will be getting the better engine with no bugs. I just put a new 225 on my 21 Conquest with fuel flow and all the other extras. Hondas (I've had five over the years) are as bullet proof as you can get.
