Hello? Anyone have a single 400 with a 4 blade prop? Anyone?

Here is some information, you may already have, not sure.

I bought a 4 blade as a spare, pretty close as a spare goes I think,

Could not find a used 5 blade anywhere with these specs

I'm surprised that MS used a 1-3/4 shaft on the 400 with Yan 6LYA.
My 34HT and 6LYA has a 2" shaft.

Sorry, I should have mentioned that I had the spare bored to 2"

That makes sense and opens up more possibilities if reboring not too expensive.
