Has anybody repowered a 424 with a saildrive and eliminated the vdrive? Is it even possible?

Anything is possible with enough money. Is it worth it? I'd say 'No!'. There isn't enough space for a saildrive inasmuch as the engine takes the space between the prop and rudder. If you didn't mind having your engine in the doorway between the aft cabin and main cabin, you could do it.

Aaron,
I'm sure it is possible, although it would certainly require a lot of fiberglass work and some serious design work. Have you talked to saildrive owners? I think you might be exchanging one set of problems for a bunch of much worse ones.
For example:- Most saildrives are aluminum and zincs are essential to preserve the unit. I have a friend who owns a Sweden Yacht 38 with a Volvo saildrive. He neglected to have the zinc collar replaced for 2 seasons. The result was a $10,000 rebuild of the lower unit. A lot of that may have been faulty wiring on our dock, but still …
- Many saildrives require a haulout to change the crankcase oil.
I would certainly be interested to hear if anyone has converted a P424 to saildrive. I am aware of a few advantages (besides losing the Walters gear).
- Prop force inline with the direction of movement (instead of down 20 deg)
- Excellent control in forward and reverse. My friend can park his S38 like he has a bow thruster.

It’s also less noise and no alignment problems which is what I liked about the idea.
Today, while searching (without success) for the mystery oil leak in my westerbeke, I found my relatively new absorbent pads were saturated with Diesel, so I’m thinking about all of this again.

Well, the oil leak can occur with a sail drive as well, and the force directly in line wouldn't be a useful thing unless you were going to plane the hull.

My boat neighbor got a brand spanking new Tartan 3400
last year. What a piece of sh**. The saildrive and the
boat. He had an oil leak in the drive. In order to
repair it they had to haul the boat, grind out a big
hunk of fibreglass fairing. After replacing the
seal(in which the lower unit had to be removed) they
spent two days refairing the hull. Progres??? I’ll
take the old stuff anyday. At least I can repair it
myself, anywhere!

I agree – Saildrives are like little underwater jewels. They're delicate, complicated, and require too much maintenance. For racing they're probably the cat's meow.
For general abuse, not so much.
If you want more control for the boat and you really want to spend huge amounts of money, get a bow thruster. For less money, widen the rudder 6″. It is my opinion the major problem with steerage is because the rudder is too small.

I considered it when I repowerd my boat. In theory, it would be possible. Some glass-work would be required, but I would guess that the work would be no less difficult than replacing an engine bed.I wouldn’t even consider a Volvo-Penta. Yanmar makes a couple of models, but their largest is only 50HP. This would probably give performance similar to the W60. They used to have a 75hp model, but I don’t see it anymore. The 50hp engine is much smaller than the Westerbeke engines. This would leave quite a lot of room in the engine compartment forward of the engine; maybe enough for a small genset. I think prop rotation would be right-hand, so the boat would behave differently.

Hehe, not yet, I’m still mulling it over.

What about replacing your engine with a generator and considering e-pods?

I’ve been thinking about this as well: http://shipsrecord.com/blogs/patrick/archive/2008/03/15/secondary-propulsion.aspx
Not much concrete in terms of facts yet.

Owners no more...
Thanks Dawn and Patrick! -
Without a doubt, it would be my preference to go diesel electric. The Epod you mentioned I think is underpowered, glacier bay, soloman and fischer-panda are (at least) $10k higher cost that a diesel repower.
I suppose I could put two of them suckers in there, but it would probably be a lot more drag sailing.
