[Are twin engines needed for a CONQUEST 255 to run properly?] Thanks

Well my 23 sure could have used them. Single 225 was ok. But that's it on performance. Given the 25 is even heavier, I would think even a single 300 hpdi would be marginal. So IMO, yes you need the biggest twins you can afford.

I think any Whaler, 18 Outrage and up, should be running twins, if offshore duty is involved! NO, you do not need twins for a 255 Conquest to run properly. Boston Whaler does not sell boats that do not run properly. Others may, but not Whaler.

As Mr. lhg stated, Whaler would not sell a boat that does not run 'properly'.
However properly is subject to differing points of view. From a performance standpoint and the fact that I travel offshore Twins are a neccesity. Sure a single can push the 255 but consider it is going to be lackluster. With the 2OO YAMAHAS, the 255 loaded with fuel,water & hardtop will do 45-49 mph. Thats moving almost 9000 lbs. Whaler will probvide you the performance specs on all the motors available, call customer service. You can judge for yourself.
If youre just gonna cruise inland than a single may ft your needs and I have seen a few VERY resonably priced on Trader.

I have run the boat with alot of different loading conditions with a lot of different power options. In my opinion, the perfect power package for the 255 is twin 135 Opti's. However, if you don't plan to run with extra heavy loads, the single 225 is a good package. Very fuel efficient.... nice cruise.

Boat dry=4900lbs.
hardtop=500 lbs.
fuel=1000 lbs.
water=120 lbs.
equipment=500 lbs.
motors=800/1000 lbs.
3 people @ 150/200= 500/600 lbs.
I'd want the max hp that the boat is rated for.
