Bolting an engine to the transom

Please can someone advise me on the above?

Do the bolts go thru the front of the transom with the nuts on the outboard bracket ( my preference) or vice versa, or does it not matter?

The inside of the transom would be neater with just the bolt heads showing, but I am wondering if there is some other reason for doing it the other way round. I would like to put a bolt lock on the 5th bolt which I guess needs to be on the nut side.

Hope that makes sense.


Many thanks.

There was a thread some time ago discussing the pro's and con's of which way to put the bolts.

It was the thread about the chap who lost and engine in the US and then dived down to get it.

Someone with a better recollection than I will point you in the right direction.

I can email you the Suzuki DF25 - DF250 rigging manual. It will answer your question. Just let me know your email address.

Most motor Ownwer's Manual recommends to install the bolt's nuts inside the transom with washers on both sides. If the nuts become loose with time will be able to see them from inside the transom. Nuts should be checked periodically. Like bolting my motors with double nuts, just in case...

Happy Boating

Most if not all my past and present boats had the nuts inside the transom

Bottom bolts, nuts inside boat. Top bolts, nuts outside if hydraulic steering fitted as ram may touch the ends of the threads when engine is on full tilt and full lock.
