I bought this motor more or less sight unseen a couple of weeks ago. $500 with a beautiful rolling,really well balaced, narrow width square tubing stand. The tilt trim needed an o-ring on the manual release which with a good flush of the system now works like new. I also flushed the lower unit oil which had no trace of water to begin with.This motor shifts sweetly. I.When I started it, the water flow wasn't strong and it got too hot to keep my hand on the cylinder banks. I removed the cylinder head covers to find salt and silt packed into the thermostats, though the water passages had no blockage. After installing new thermostats and a new water pump, I ran it again. The port bank ran cool, but the starboard was still running too warm. Before I got the new valve for the thermostat housing, I ran the engine without the housings for a good amount of time. A good deal more gook flushed out of the system. I observed better water flow on the port side, but the starboard seems adequate. With the housings in place, but no thermostats, both sides stayed approximately even temperature. I have the new thermostat kit, but I had a complete hip replacement 3 days ago, so switching 400+ lb motors on the boat, in the water,with my dock mounted hoist, seems to be frowned on by my surgeon, wife, etc.My boss on the other hand wants me to come back and deliver heating oil and diesel to boats. I turned 68 3 weeks ago, so I would like to get a couple of fluke, but I guess it'll have to wait.If the engine turns out to be a honey, i will use it until I fix my 94 225 Evinrude. Then I will put the 235 on my old 21' Proline cuddy, and sell it to some lucky person for $2500 or so.
