Have you checked the water strainer? I had the same identical situation, and it ended up being that the water strainer was clogged with algae... (Thanks again David)... it could actually be that simple.

Most water strainer at least for diesels - are very small and under sized resulting the symptoms occurring more heavily. The reason why it is not happening at the dock is that you are not putting any load on the engine and therefore it draws less water...When motoring it draws more and the water strainer when clogged will more readily restrict the flow that is required.... so it may not be the heat exchanger after-all....(I am assuming this was something not looked at)....

Also (maybe this needs to be another post) there is no raw water screen between the thru hull and raw water impeller. Shouldn't there be one to catch debris coming in? Thanks for all the help!
Yes, there definitely should be. Mine's in the bilge, near the thru hull valve.

Here's a good photo I just yoinked from Google Images, but I'm guessing it's from a power boat. (look at all that space!)

All the previous suggestions sound right on. Last year I was having hot engine issues, did everything suggested, plus flushed the fresh water cooling system, replaced thermostat, impeller, & several hoses. Then ran a product called Barnacle Buster Concentrate from Trac Ecological through the system. I let it sit overnight and flushed it out, no more worries. I plan to do this probably every other year now.

This is the link I was looking for. Great stuff, worked well for me.

I had a dream, I was sailing, I was happy, I was even smiling. Then I looked down and saw that I was on a multi-hull and woke up suddenly in a cold sweat.

Perhaps you have a problem with the shaft alignment? Even if you ran the engine at the dock on forward I don't think you did it in full power did you? In which case it would overheat only on water when in cruise speeds...
