I just purchased a used 2 stroke 4hp Yamaha outboard. It has very few hrs. I think it is a mid-nineties model.<br /><br />I took it out for a test today and it runs great - however, when it gets warmed up, the water indicator stream slowly starts to reduce and eventually turns to steam. When I let it cool down, the stream starts up again fine - only to dissapear in a few minutes.<br /><br />Is this a symptom of a failing waterpump? <br /><br />I went to drop the lower unit (removed two bolts under the cavitation plate) and discovered that there is something attached that prevents me from removing it. Gear shift?<br /><br />HELP! I don't want to spend another $200 at the Yamaha dealer.
