Hi Carter,
The general guideline is 1kW of motor for each ton of displacement. You can use much less in fair weather but for general safety, the 1 kW per ton is a good compromise. With 15kW, you should be able to hit 90-95% of hull speed at full throttle.
It's your boat and you can put in whatever you want, but our guidelines come from the combined experience of many installations.
I don't know where you sail, but if you're underpowered, you might run into problems if you need to motor against a current and a headwind when heading into a harbor.
A 12" prop sounds pretty small for a 45 boat, my 30', 5 ton ketch was running a 13" prop on the 12hp Yanmar diesel. I went up to 13.5 when I switched to electric.
Fair winds,
Eric
BTW, I think that a $6000 discount seems pretty generous. I wonder what a 40hp diesel installation costs...> ________________________________
