Are you having a problem or just wanting a manual. Those manuals can be tough to understand how to use, but if your having a problem we can probably help you find the section you need, and maybe some advice.

Don thanks for the reply. My father-in-law and I need to change the water pump leg and the thermostat and he wants to get the manual just for reference at this point. But I know I will be back to the forum about this engine as it has been running hot. We are just starting with the parts above to see if it helps the issue.

Here are a couple of files I put together from the manual that just puts the manual sections in one spot for a couple of the more common jobs.
You really should pull the complete drive to change the impeller, there is also maintenance (like greasing the coupler splines) that can keep you from having to pull the engine to replace the coupler.

Might also want to visit the stickies at the top of this forum. I'm sure there is information you want for engine and drive in them.
