I would think you would need to disclose the type of boat and engine combination before you could get an informed opinion.

would go for the ad41 , i think the twin 150hp would be a bit under powered.

No brainer AD41's with duoprops, there is no downside to having duoprops and they give better handling and performance. I've got two AD31's and whilst reliable they are not smooth in a twin screw boat, the AD41 sixes are much better. The 32's are very powerfull but you have the extra maintenance of the supercharger.

Extra maintenance of the Supercharger?
One extra belt, plus check the oil level a couple of times a year. Not a biggie.

the 32's give you more more space in engine bay, much quicker acceleration due to torque curve, weight saving and probably fuel saving. against the 32's is yes extra belt, and probably touch noiser due to be 4 cyclinder. power to weight much same, as 32's in reality are nearer to 190hp than 170 the paperwork says.

If the Sealine 310 you are looking at does have the bigger engines, make sure its checked for stress cracks, is easy to drive them too hard.
