I have my 'new' 240 in the water finally and noticed last weekend that the temp was up around 165 - 169. My last boat ran around 140. the temp in the DA is steady and I read that this temp is normal for a closed water cooling system. Does anyone know if it is a fresh water or closed system? the motor is a 305 merc (alpha I)
