overheating outboard

[jeremydotson]

I have a 1989 cabrea 85 horsepower outboard. I just had a new water pump put in and I still am having overheating problems. Thought it might me the oil injector so I started mixing my own and had 0 problems for a week, Overheat sensor came on yesterday.This only happens at higher speeds never while idleing.Any ideas???

Re: overheating outboard

get a new 1 and put it back in.they are in there for a reason. that might be your problem belive it or not but they are there to restrict and channel the water flow

Re: overheating outboard

Re: overheating outboard

here is a thought is the engine really overheating or could it be a bad temp sensor ? other then that i am all out of ideas.

Re: overheating outboard

im pretty sure its getting to hot because when it went off yeterday i looked back and the pee hole was putting out steam

Re: overheating outboard

steam ??? does it put out water at a steady stream ? was it over heating before the new water pump also

Re: overheating outboard

Water pump seems to be working fine steady stream while ideling or cruising at low speeds

Re: overheating outboard

Common causes of overheating:<br />1. Water pump<br />2. Thermostat<br />3. Cooling passage obstruction/clog<br />4. Head gasket<br />5. Bypass valves or check valves or cooling deflectors<br />6. Too much advance in ignition timing<br />7. Too lean mixture<br />8. No oil<br /><br />There are probably some others I forgot.
