outboard fixing bolts question

hi guys, is there a good reason why the fixing bolts have the nut go on the outside, majority of outboards i have come across have the bolt going through the transom from the inside and nut on the outside, any reason for this
im just curious if someone was going to steel your outboard doesn't this make it easier

Nuts on inside are securer from theft. However access can cause issues for either way round. Don’t reckon it matters unless your fitting a lock.

re bolts

i guess just personal preference then, unless fitting a lock, but i guess theres nothing wrong with fitting that on the inside ether

When fitting front mount hydraulic cylinder the nuts to the outside as the excess thread on the bolt may touch ram on full tilt and full lock either way.

Yep.My Opti fouls that way round, so nuts are outside.

I worked at Yamaha dealer for nearly 20 years. I never once fitted an outboard with the nuts on the inside - they look so much neater with them on the outside.

If it was a nice boat I would trim the bolt down as well to have 10mm protruding and refinish the cut ends on my Myford.

i guess at the end of the day, if some is determined to have your outboard don't think it would make much difference whether the bolts are on the inside or outside.
