I would expect the various twisting moments to be minimised by having the engine down, but with the heaviest part being so close to the axis it rotates about, I'm not convinced it makes a great deal of difference from a structural point of view.

The leg will exert various twisting moments, but assuming it weighs much less than the engine block and guessing that its centre of mass is between a quarter and a third of the way up, is it going to make much difference? I suspect not enough to worry about it.

If the whole engine was of a uniform density, the answer would clearly be to tow with it down, but they're not, so it isn't (necessarily).

I suspect more practical concerns are more important: if the engine's down, it might be too close to the road, if it's up it might be resting on a tilt lock that might not be quite strong enough, or a piece of wood that's not always that reliable (one of our old, unassisted manual-tilt 40hp two-strokes chewed through a chock a couple of years ago, and that was just crossing the road on a trolley).

I towed over 550 miles last week with a 40HP 2S supported in the raised position with a piece of 2 x 2 wood. Perhaps I was taking a big risk doing that

I use the bit of wood to save the tilt mechanism but probably will fabricate something to brace the leg direct from the trailer this year to save the transom from flexing on longer journeys. Some of the potholes are getting HUGE but at home we're getting the bike race next year & they've already made a start filling all the ones on the route....

Do they not make "transom savers" in the UK?

Over here we use braces like this. http://cdn.stripersonline.com/a/ab/a...ttach39898.jpg

BTW there is some debate over the utlity of things like this, particularly for adequately built fiberglass transoms.

I've Tow'd All over the Place,and continue to do so..Somerset to Scotland is a Slaap,and Carnarfon last weekend is a Good Trial too.. I definately recomend (after trying different options) Rams in 'Down' on to Block of woood with engine turned to right,and Strapped/Supported in possision (I use small Ratchet straps around Leg to Trailer) in position to stop Latteral movement.
I would say I think the Bigger (Heavier) the engine the more important it is to support it as much as Poss.
With the Roads as they are these days...I also Check All the Fixings!... Often.

Scotland and Wales?!! Wow, that really is a slaap.
Mind you, if I lived anywhere near Taunton, I'd also wanna get the feck out.

I have looked at these on ebay and they all seem to come from Australia and the U.S. are they any good ?

I have one. It supports my Yam F60 independent of the little locking lever and doesn't come loose. So it seems to work, but I have never cracked a transom either so I am not sure how I'd tell if it "wasn't working"?

The mercury manual shows these outboard trailer bars with a v for the gear case to rest in but I haven't found where to buy one in the uk. Seems like a good idea to stop the engine bouncing when towed. In fact the manual states you should not rely on the small tilt lock and rams when towing.

Who sells them in the uk I wonder??
