As an additional information, at least initially, the new Volvo Penta IPS will only be delivered as a twin package. Included is the electronic shift/throttle and the electronic steering, making this a dream pack for the shipyards. One hole in the bottom for the steerable drive including water intake and exhausts. Only a set of wires to connect to the bridge/flybridge!
As an illustration I have put the package with IPS 500 into my 40 feet design which I believe would be an ideal combination for a cruising speed near 40 knots.
