    Hello,
    I try to find the best propulsion system for a high speed planning boat,its a trimaran with these characteristics

    Length=10m
    Beam=5m
    Maximum speed=60 knots
    Cruise speed=50 Knots
    Weight=4.5 ton

    but i have problem to decide between stern drive and outboard propulsion systems.
    Also i want to know how many propulsion systems is more proper for this situation(i.e. 2 or 3)?
    Thank you.

    Outboard is easier to install and remove if not to your liking.... How about a longtail or surface drive :D:D:D:D There have been images of 6 or so 250hp outboards around - wanna go for a record? 10 units?
