Hi Martin,
I recently completed my replacement of the old SBE12 with a 5.5kW drive from Propulsion Marine in my 1964 Cheoy Lee Bermuda 30. With the Yanmar, full throttle delivered about 5.5kts with a 12x10 prop in the aperture. With the electric drive, I can hit 6kts with a 13x15.5 prop. More power on tap, but a little more prop walk in reverse. If you search the Yahoo group site, you can find some posts from ealier this year descibing my boat's observed performance.
If you're looking to convert quickly,buying a complete drive system with proven results should save you a considerable amount of time.
Fair winds,
Eric
Marina del Rey, CA

So that is a "cheaper" way to go if your own time isn't worth much and your skillset for such things is good (mine isn't particularly, but I enjoy it and it's cheaper than golf). But you may lose the season to typical DIY issues. You only "save" about 2K or less going that route.
