any reason not to use stainless head bolts in outboards?

Poor CRAP cake, he has to make stuff up as he goes.

Yes , stainless fasteners are fine. Matter of fact all new marine engines come with them.

I don’t need any, anymore.

My take on the situation as of now is:
-for rod bolts? Proper high strength bolts. No homebrew hacks, not negotiable.
-for outboard heads? High strength bolts not called for. In fact, the kind of torques required to achieve preload on a high strength bolts might be very hard on aluminium threads. There is room here for homebrew hacks… As long as you have valid data as to what torque to use to achieve proper preload… Or else are an experienced marine mechanic and you know what works from, well, experience. I have book smarts, (engineering degree), but I am not an experienced marine mechanic, which is why I’m here to sponge information off of you lot.

That about sum it up?

Yes Peter, that about sums it up. You school boy's design and make it.

Us ole country bumpkins, show ya how ta use it, fix it, make it better ...

Just use good clean oem bolts and make sure all the threads are clean. Refer to merc manual for lube and torque spec guidance. Done

I read it as wanting to swap from stock to aftermarket stainless which i would never do, ever. As for steel bolts not stretching in aluminum blocks? Better not run and LS/LT motors. Those head bolts are torque to yield and stretch right out.
