I could understand the C32, but sticking 35xx engines in a fast powerboat is totally unheard of. There's much more than power alone to consider, in fact. Leaving aside the 3512 which is a 59 liters monster, also for the 3508 there is no place in any fast pleasure boat. Just by heart, and without bothering to check the specs sheets, I'm pretty sure that it's MUCH heavier, taller and wider than the C32. Not to mention the narrower rpm range. I'd rather have one in a tug than in a Baia, Magnum, Itama and the likes!
