Re: Powering PDQ 44

This fuel consumption is quite close to what we get with our Volvo MD2030 (29hp, 3600rpm) on a Manta 40. The speeds are a bit low for us by half a knot.

Re: Powering PDQ 44

The data were for one engine only. It just peters out before hull speed. Maybe the prop is too small (it goes right up to rpm limit).

Re: Powering PDQ 44

You need to get up into the other hemisphere. Up there, the typical cruising cat is probably 8:1 or less.
