Hi there,<br /><br />after two years of heat soak problems and at least 7 trips to dealers the heat soak problems may be fixed but a cause not found as yet.<br /><br />the dealer had this motor for the last three days. Re-tuned everything and ran in gear for hours at a time. noticed water from pee-hole hotter than other Hondas. <br /><br />Took out thermostat and ran motor without one and instantly the motor ran much better. No cough or miss at idle.<br />He replaced plugs with equivalent iridium plugs as well.<br /><br />i picked boat up and took out for a run. This is the first time since new that there was not one miss / cough or splutter throughout the rev range. After letting a heat soak to occur I turned motor on and it went straight into a smooth idle. All fixed on this occasion.<br /><br />I know the proof with be in the next couple of months as we approach summer.<br /><br />Is there any damage caused by not having a thermostat.???<br /><br />Thanks everyone, espescially Skinnywater and Hondon
