Mine are KAD43's
I was tempted to go for KAD44's but was worried about 'over' electronics on the boat and maybe reliability problems. As it happens I think there have been very few problems so fears unfounded.

AsI understand it the KAD42's don't have silencers fitted on the superchargers whereas the KAD43's do. The supercharger's on the 42's are very noisy and I have had silencers fitted - you can't hear the supercharger's with silencers.
OK finally found V&^*o price list, Diesel Aquamatics on legs are K if supercharged etc. as someone has said, with no M so therefore KAD43P etc, the inboard equivalent on shafts would be KAMD43P, I'd assume M being marine gearbox or something similar.
I thought T was turbocharged but although the inboard uses a T designation the same engine on a leg doesn't, eg. TAMD31P is Turbo, marine gearbox, AD31P is same engine on a leg, so I'm a tad confused.
A friend of ours is Svedish so I'll ask her whether M is gearbox or whatever in Swedish.
OK update, just spoken to Swedish friend, gearbox in Swedish would be Viksundorfer(sp) so M don't mean gearbox in this context, her comment was could be Marine as Swedish Marine is Marina.
