DoubleD

I recently acquired a used boat with the engine listed above. I've been doing a little PM since I don't know the history of how well it was taken care of. It does run fine, though. I've looked at all the parts schematics and read the owners manual, but I cannot find any mention of a thermostat or where it would be located on this motor. I currently don't have the service manual right now either. Does anyone know if this model has one, or where it is located?

It's a 3cylinder, 2 cycle, SN is 654****

I've been wondering about this for some time, and I would like to have your opinions. I am noticing that lately younger people have no idea how to spell or write even remotely accurate. Firts off, I have poor spelling and punctuation, and I believe that the "Spelling Police" are annoying. However, I think that with all the text messaging and writing in this new online trendy short hand has made it to where and average 16-18 year old probably wouldn't be able to pass a 5th grade English class if it was taught to the standard.
