Sorry for your kablooey Gene. That blown motor is worth a lot more than you think if you have the patience to part it out or find the right buyer that wants to either rebuild or use for parts. L/U, Cowl, Pan, prop, controls, starter, flywheel, ECU...all valuable.

That said...the yammy 2 strokes have a very good reputation. The trouble is, on a 10 year old motor, I'm not sure it would have an ECU so you could get actual hours off of it and will be relying on the seller to be honest and accurate. You might be looking at a 10 year old motor with 25 hours on it or 2500. Big difference and both might look brand new. With any used motor, get a good mechanic to do a visual inspection and a compression test. You can also ask for a cylinder leak down test which is supposed to be an even better indication of compression. Assuming it all checks out, I wouldn't be scared of it if the price is right.

Here's some random links with some engine pricing:

C&O Marine/ Engines

Jaco's Marine - Boats , Mercury , Fishing Boats, Team Jaco

The second dealer - Jacos buys "blowed up" motors at wholesale prices....that's always an option.
