I knew it was normal, but I had never paid any attention to how high the temperature got when I shut the engine down with the 142 degree stat. When I used the 160 degree stat and had the problem restarting, I noticed that the temperature had gotten up to 175. I guess at about 30 degrees above normal operating temperature it won't allow it to restart.

Update... The boat is at Flash Marina and they have recreated the problem, run it on the computer and they have no new information for me except that they are calling for technical support :-( Hoping to hear more today so that I can spend some time on the water before the snow flies!

Normal operating temp for the LT1 is 160 degrees. (same as the temp rating as the top t-stat)
If you are normally running 20 degrees warmer than your thermostat....you have a cooling system problem. Check, raw water pump flow, look for leaks from the circulation pump, and make sure that you have the correct t-stats and that they are installed correctly and are operating correctly...search for blockages in the cooling passages. Note the top t-stat needs to be a 160 degree one, with a by-pass hole drilled in it. Make sure to get the mastercraft one...there are many automotive ones that won't work.

Thought I would put some closure to this for my problem, since we never heard back from Sammy! 95 Prostar with LT-1. After eliminating fuel problems, The folks at Flash Marina ran it on the computer, checked all codes, found lots of fun stuff relating to running way to hot. They cleaned out old impeller bits (previous owner replaced the impeller, but didn't wonder where the parts went), checked for other obstructions, and looked at the thermostats. The previous owners installed an automotive 180 degree thermostat in the upper. So the boat was running at 180 and heat soaking above that.
I REALLY wanted to put the right thermostat in and test the boat this weekend, so up to CT for the closest thermostat available (apparently I could have bought an automotive and drilled it, but I wanted to do this right). Installed the thermostat today and spent a little over an hour tolling around Lake Hopatcong, starting, stopping, idling, shutting down and restarting, etc. Temp statyed aroudn 160 - 165 with a bit of heat soak, but nothing alarming. Boat ran GREAT!!! Very excited to put this behind me, and that I have learned ALOT about this boat and basic repair and troubleshooting! Thanks to all who provided insight and ideas - Much appreciated! See you on the water! |
