If there was a risk of buggering the transom through towing with the engine up I'd be really worried the transom wouldn't be strong enough in general, the extra load created by having the motor up towing can't be any worse than bouncing around in a big sea.

Especially not with all the horsies neighing as well - I'd rather find out it was due to fall off on land...

The Etec has a trailering support which is about half way up so that's what I use.

With the motor up bouncing down the road is putting forward and aft forces on the transom trying to bend it. Over time, if you try to bend something backwards and forwards it is more likely to fatigue.

With the motor down the forces are more up and down which in my opinion is less likely to fatigue the transom. There isn't the continual leverage trying to bend the transom backward and forward unless you are wave jumping.

When we check for a wrotten transom, we tend to have the motor up and rock it back and forth to see the flex. It doesn't work so well with the motor down. When up it acts as a large lever.

Of course having it down only works if you have enough clearance to the road.

When the motor is in use (ie trimmed down) the strain is on the mounts etc. When trimmed up most of its weight is then balanced like a sea-saw across the transom. Leverage does the damage.

I guess you go with what you've been told. If Ribcraft tell you that, I assume they will cover any damage caused to the transom too likewise with Yam etc.

Trimmed down with a block of wood the risk is taken away altogether and I like that option.

Snap. It took me longer to type out though!

Suzuki hand book

I have just read Suzuki handbook it says engine down if enough clearance or part down with support of a transom saver bar or similar, I have 5 year warranty with Ribcraft so I will need to Re-check with them again.

On a new build I'd say your fine either way. On a 5 or 10 year old hull is where the debate would be of any real significance.

I do agree and I will change how I tow from now on but would still like to think my transom is strong enough to cope however I tow it.

My Yamaha manual says "The motor should be trailered in the normal running position. If there is insufficient road clearance in this position, then trailer the motor in the tilt position using a motor support device such as a transom save bar"
