Re: 150 optimax water pressure low
The two most likely canidates for your low pressure at idle problem are: a)poppet valve<br />b)waterpump<br /><br />a.) Even though you had this replaced, this would be my frist guess. When you replaced the poppet valve did replace the diaphragm, grommet, carrier, spring, etc. as well. If the poppet isn't seated properly or the grommet wasn't installed correctly water will empty the block through the exhaust before it can fill the block up with water. At higher RPM's this isn't a problem because you have so much more water flowing and this isn't an issue.<br /><br />b.) Same idea, if it wasn't installed properly you are not getting enough water. When it was replaced what was the condition of the old impeller, if it had broken vanes you need to make sure they aren't clogging anything. Have you checked the new impellers condition. When the water tube is inserted into the water pump, sometimes the water tube folds over the grommet/ring inside the sleeve.<br /><br />Do you have good water pressure at higher RPMs? While your at it replace the tstats. And with the tstat housing off stick a hose down there and flush it out, maybe there is a clog. <br /><br />Good luck and lets us know

Oh yeah, good point Tim. <br /><br />codn-<br />Did you mean 5 psi or .5 psi. 5 psi at idle is fine, but the .5 psi is bad.
There are lots of good features and specs of it. But I have seen lots of people complaining about the outboard motor’s issues.
It is kind of similar to the previous one. But the diagnosis and the solution of the problem are a lot different. more
In some cases, running the motor at higher RPM cools it down. [links]
Yes, that will be the correct one needed.
When I ordered the parts the discription wasn;t detailed enough on the web site and I ended up ordering extra parts that were not listed in the kit. If you need a pump kit for a 470 don't order anything else it is all there in the kit.
