New to me 2011 Sho250

[Hawglife]

Hey all I am looking at purchasing a Sho250 from someone and wanted to see if there was anything in particular to look for on these models.
Compression check is really all I know. It's already on a stand so won't really be able to run it.
It has 463 hours and all anodes have been replaced and whatever other maintenance is required has been done to it.
Motor physically looks clean and I've heard and seen it running on the stand.

Anything else?

The cooling system. Hard to test that on a stand. They can pee water at idle from a hose or a bucket but under load, they can over heat if not up to par. They tend to have a weak water stream (by design supposedly) so the only way to really know that the cooling system is ok (that I know of) is to run it hard and watch the temps and/or pressures. The temps will climb to the hot side on the yami gauge in about 5-10 minutes of high rpm's (48-52000 rpms or more) if there's a problem.

Another thing that's hard to test on a stand: They can leak oil internally. Try this after a a good hard run. Shut down the motor. Tilt the motor all the way down (tucked in) and let it sit for a 3-5 minutes then start it up. If it smokes (like a 2 stroke...or worse), it may leaking oil internally.

Check the steering components and the trim/tilt pivot point areas closely for rust. (https://mbgforum.com/topic/1392-yama...tube-corroded/)

I'm not a mechanic, but from past experience, I would only buy a motor after a real world test run on a boat in the water and an inspection by a mechanic or a written guarantee of some sort.

The 250 sho is a great motor when it's been cared for properly. But like any motor, can be a money pit if not. If you can find a reputable mechanic to look it over, that would be optimal.

Not trying to bash or steer you away, but you asked for things to look out for. Good luck.
