Couch motor mounts in SJ- How?

[ItsRixter]

Hi guys, I heard many of you run couch motor mounts in a SJ because they are beefier than stock mounts. I tried one and the bolts holes are larger. How do you make the bolts hold the mounts in place?

My bolts have a lock washer then a appropriately sized flat washer below the head
Ace hardware has SS flat washers

The mounts dont slide around since the two bolt holes are larger than the bolts going into the hull?

No they don’t, those mounts are taller and you have to push the mounts outwards to get the engjne lower and or drill the holes even larger if needed... the mounts stay put and usually are against the bolt anyways

When the bed plate is bolted to the mounts it will in a sense hold them in place.

Exactly all of this...
SJ mounts no longer exist to me in my mind after seeing how much longer couch mounts last.

Yes any year waveraider or any yamaha that came with a 701 or 760. Not sure on the 1100 mounts.

Tig weld washers to the mount to center the bolt hole
