Hi Gents 
)<br /><br />I have just bought a 4-stroke 50 hp merc from '99<br />When the engine runs I only see very little<br />water from peehole.<br />I haven't had the engine going for more than 10 minnutes in a row...<br />Is this normal on this model due to a thermostat or something? or could the cooling system be blocked with dirt, or maybe defect impeller?<br /><br />what do you guys suggest I do?<br /><br />thanx
