Mr Willk I'm sure you know but take care not to be driven by max power rather than drivability and reliability. Reliability is obviously essential to peace of mind wherever you are on the ocean and especially on your own boat rather than a borrowed one, you really don't want to be fekkin about with something you don't have confidence in. Aside from the hassle of repairing, down time and cost. It must never fail you as sea. Never is probably not certain but you need freedom from that worry. 10 miles offshore in twisty turny difficult water, the very time the drive line is stressed, you want the certainty that you can clip in and out of gear, steer freely and throttle without concern. You'll need that at Cushendall too...be embarrassing to get yourself grounded on those rocks while turning.
Which leads on to drivability, plenty of low down power and freedom from turbo lag is much more important than a few knots higher top speed. Having both is good, obviously, but if there's a choice it has to be a sacrifice of top end.
Imho as usual, of course. Just bringing you back down to reality from that talk of maximum horse power and drives that may or may not fail.
