Hello. Just replaced the thermostat and gasket due to engine not getting up to temperature. New thermostat didn't make a difference in operating temperature though. Just went over the whole motor carb kit, impeller, leg oil etc. Starts good, runs well but I've only ran in a barrel haven't hooked it up to a boat and run at full throttle. The one thing I'm wondering is if the stat spring was weak would othe water unseat the stat? Putting it together it seamed the spring had lots of tension. I'm at a loss and would appreciate some ideas. The stat is down low in front of the cowl latch and clearance was such an issue I ended up removing the head to remove the water plate. I'm discouraged to think of doing it again. Thank you.
