Petrol cost $1.05 a litre and diesel $1.30 a litre.I would need to use the rib alot before I broke even with a diesel.
I thought for the same weight you can get more HP from a petrol than diesel.
With a sterndrive you can have a swim deck at the stern which may compesate for the room lost in the rib compared to an outboard. and the weight is futher forward and lower with the sterndrive.
If I was to use an outboard,I would possilbly have two motors so the weight would be the same as the diesel sterndrive and the same price aswell.( a couple of 140hp $32000).The petrol sterndrive seem to be the cheapest option except for one 200 to 250hp outboard which is the same price as the petrol sterndrive.
Or is my thinking not quite right?
So thats why I was asking the orginal question about petrol sterndrives.
thanks for the replies
