250 SHO yamaha on a 23 SF

[FAS]

I am on the verge of repowering my 23 SF I have a deal on a few 250 yamahas, new 4.2 only...love my current 250 ox66, but its been giving me problems.checking weights on yamaha vs suzuki. looks like the yamis sho is 505 lbs and throws 271 hp at the prop.my boat is a 30" transom, so ....modifications to the lower are needed to make it work for me, thats OK.not a huge deal.. I am not concerned about fuel consumption at what RPMs....what does a 250 zuke weigh and HP at the prop?lets hear what it is, hope some one knows ,VS a 4.2 yams,250,standard or a SHO....
