 if I didn't turn you off with my posting about outboards-the main advantage of which, when they stop working ,one can just unbolt them and let them sink to the bottom- i have a Nissan 9.8 four stroke,4 blade prop electric starter and 25 inch foot with 60 hrs of use- I'll even throw in an adjustable hanger- but I don't recommend it unless you are absolutely convinced that this is the way to go.
 Boulet lemelin can make you a sail drive from an outboard and Johansen will sell you a Honda powered sail drive- $5000.00 or so

with all due respect and after having owned a few boats with outboards- the plywood panel should be epoxied to the transom. These new 4 stroke motors generate a lot of torque and can twist that hanger right around. If you are planning to put a small 2 stroke on the boat it will work but only if there is a slight breeze and no waves. To power a laser 28 you need a motor with an extra long foot and the last time I looked these were  8 hp and up.- try holding on to the motor and you will get an idea of the twisting force that can be generated.
 If the diesel can be repaired why bother?

I get my parts thru the Canadian Distributor Keith Strutt in Kingston Ontario 613-634-8100, He has most parts in stock and pricing is same as you will get from Denmark.

There isn't any more info on that Farr 25 than can be found on google, but eventually I suspect their method and equipment will become available thru someone

The Farr 25 idea is awesome. Do you know if the bracket is a custom item? I would be willing to try the idea.

when I fully restored my engine last year, I had the chance to have the "help" of Erik Jørgensen of LSM-Diesel [info@lsm-diesel.dk] parts were priced good (Danish Crown vs Can$ helps I think). Shipping form DK was also very fast (took about 6 days to Canada). No shortage of parts there...

I'll add my reply here as well just for all to see:

I think you will be fine if you use large backup brackets on both sides (particularly on the inside) One note of interest, is when we did this here in Montreal, the fellow left his saildrive in place and he still won races with the outboard on the transom. It doesn't appear to affect the performance of the boat any and its the easiest/fastest/ least expensive solution to keeping your boat powered. I'm currently rebuilding 2 Bukh engines now. Parts are indeed getting harder to get.

I really like the motor setup on the new Farr 25.

An alternative method for engine replacement, the downside is the glass work involved.

Cheers Bill

Yes we did this last year to a boat here in montreal. We put a 3/4" piece of plywood inside the transom (18" x 18") as a backup plate. and on the outside we put another 3/4" piece of plywood painted white (a little bigger in dimension than the motor mount flange) and then thru bolted the engine bracket thru it all and it worked very well while the old Bukh was getting rebuilt. FYI we used a 6hp 2 stroke Yamaha 2005 model regular shaft with the regular prop and it pushed the boat to hull speed easily. Hope this helps

Good morning all:

The 30-year-old 8 hp Buhk is being removed from Andiamo! - sacrilege I know. I am putting an outboard motor mount on the stern, and would like to know if anyone has done this before, and if they have any particular advice.

My concern is that the stern is relatively light structurally, and if the constant flexing as a result of the outboard hanging out there will be an issue. Should I reinforce the stern?

To mollify all those who would never think of such a thing, I will have the engine rebuilt and replaced, and the offending engine removed from the stern next year. When we do race we use PHRF, not class rules, so no issue there. As well, we are planning to ocean sail this summer in Passamaquoddy Bay (tidal range 7.5 m) and like the idea of more power...
