Lucky Posted March 19, 2010 Share Posted March 19, 2010 Would you agree with me that the following is an impellor problem ?? My starboard engine overheats after a little time. The impellor housing is hot along with the two heavy duty pipes that run to it - unlike on the starboard engine where all is cold. (Ignore the bit about the connector) One of the pipes takes water from the broads, through the impellor and filter, then circulates this around the cooling system (the green stuff with anti-freeze) to keep it cool. I'm hoping I am correct so far - I'm very much learning !!. So, in theory, the impellor housing should not ever get hot as its taking water from the broads. Now, if I unscrew the black cap on the raw water filter and quickly start the engine, then stop it, it is obvious that the impellor is doing its job and water gushes out. Could this 'gush' out if the impellor isn't turning ? If this 'could' happen then I think this is the problem - but I presumed that the impellor is for exactly that, and if it wasn't turning there isn't anything else that would make the water gush... Any ideas ? Quote Link to comment Share on other sites More sharing options...
