Question 1995 Pro205 Engine re-start problem

My 1995 Pro205 starts then shuts off but usually re-start it the engine is cold. It runs good but after it runs a while and I shut it off for 20 - 30 minutes it will not re-start. It appears to be overheating. If I open the engine cover and let it cool down it will re-start. It is getting fuel and is firing properly, just won't start. I have replaced the thermostat and the water temperature sensor but it didn't solve the problem. Any suggestions?

I am running a 143 degree thermostat. Yes, I replaced the thermostat and the ECT sensor.

Couple other things... in order of simplicity how many hours on boat?

trans cooler clear of debris?
impeller new? even if not damaged or deteriorated it can fail to move water properly.
remove t-stat and test
remove ect and test
Remove risers and check for obstruction
check exhaust hose for obstruction.

With the new 143 degree thermostat it is running at approx. 143. When I shut it off it soaks up to around 160. There are 660 hours on the boat, I have not checked the impelled. I will check it and the other things in your suggestion. Thanks,

I bet the ECT is bad - it's located at the starboard side of engine. the ect looks like this...

you can get at NAPA...

Even though the impeller looks good it may have a set - pull it out and drop in hot water .. the fins will spring back.. but get a new one... I replace every season regardless of hours...

When you have the hard start problem take the spark arrestor off... and see if your not getting a good spray of fuel..

what may help is pull the trans button and move throttle forward a bit... see if that will help hard start.

There is a very good spray of fuel. Removing the thermostat made a large improvement but didn't completely Also, raising the engine cover after shut down help re-start but I would really like to fine the root cause of the problem and correct it. Thanks.
