I'll buy that. Although the manifolds/risers NEED to be replaced if for no other reason due to age. When my manifold/riser went no traces of water was found in oil pan, even running as hard and hot as it got and with allthe compression on the compression stroke. But I can see if the rings are worn that seepage could occur. I find it hard to believe that a water molecule being large will seep past the rings (with a oil film) just sitting for a short time, but will take your word as you have experienced it. Experience, however bad:banghead is the best teacher.

ok, first off, thanks to everyone who has helped trying figure this problem out. after reading this you guys probaly wont wanna talk to me again. first let me answer the questions. i replaced the water pump with a pump kit cause i had a water flow problem. it never got hot. i had the foot dipped in the water enough to make sure it was flowing before lowering the boat in the water, just as i always do, this time i saw no flow. so after doing simple trouble shooting, being an automotive tech mind you, not much experience with boats,i decieded it was the water pump. well, i finally changed it, was about to started it up but then decieded to change engine oil first since it was about due. water came out with engine oil. pulled spark plugs to see no rust or water on plugs. drained out oil, put new in and still now flow of water while running, unless i hook up the hose. well one problem was that the tub i used only came up to a few of the inlet ports on the foot. hooked up hose, boat fired off great, idled good. checked the oil and found a slight mix, no extra oil on dipstick, which would tell me that at this time no more water come into oil. talked to someof you guys last night and found out about the whole manifold/riser thing, in how they needed to be changed, guess i was blindly riding a thin linewith that one. now....woke up this morning and completly forgot about on key thing. when i first gotit to my house we had one of those weeks of rain. about the third day i was leaving for workand it hit me, i forgot to take the plug out of the boat!!!! ran out there and saw a little less them a foot of water on the deck!!!! which means it more then likely got in the motor that way, seeing how the motor is lower then the deck. honestly i forgot about this otherwise i wouldnt of been wasteing everyones time. of course its not comfired yet but im pretty sure that solves the watery oil andgood looking spark plugs. as for the water flow imsurethe manifold and riser are the problem, it will be my first step of action besides flushing the oil.

Thanks for coming clean. Just kidding. Hope that is all it was. You aren't the first one to leave a plug in.

Been there, done that, have the T-Shirt. Leave the plug in and water stays in. Leave the plug out and water comes in. Both have happend to me. If the water was on the deck, then that probably is all it was.

Drain in bilge and let it flow out boat drain? Pump out of dipstick tube? What I'm really asking is how you know the water really came out of the oil pan? When at what point did you change the oil, before the water was found in the boat or after the boat was drained. <P class=MsoNormal style="MARGIN: 5pt 0in; mso-pagination: none; mso-layout-grid-align: none">How do you know you have a water flow problem (since it never got hot) to the engine driven water pump. Exhaust water expels from the engine through the flow through prop. TestFoot waterpump test). A set of cups will force water through the engine with bad water pumps. Remove the hose from the out drive that goes to the engine driven water pump at the engine pump. Start while foot is in the water (don't use cups). Foot impeller should pump water through it at a rate of about 5-7 psi (I have a water pressure gage on my 350/IO WOT 5-7#). Next if you have flow replace hose to engine water pump and remove hose going to riser (engine water pump test) and repeat test. I cant see (even tho you are going to replace them) where the manifolds/risers would inhibit water flow unless they are stooped up like a stooped up radiator in a car, which I can't see how it could happen.<SPAN style="FONT-SIZE: 12pt; FONT-FAMILY: 'Times New Roman'; mso-fareast-font-family: 'Times New Roman'; mso-ansi-language: EN-US; mso-fareast-language: EN-US; mso-bidi-language: AR-SA">When you replaced the impeller did you make sure it was correct...install the drive shaft moon key in the impeller sleeve

again, thanks guys for all your help and patience. ok, i change the oil bye the drain plug, i have a really then oil bucket we use at work that just fits. as soon as i pulled the drain plug i saw water coming out. enough to suspect a problem. the rain was way before even changing the sea water pump. so the water in the oil happened before the boat was started. in fact, i didnt even start the boat before changing the engine oil and finding water. it came to me yesterday when trying to figure out how water was in the oil that i had left the plug in the boat and it filled partly up with water. which i know for sure now was the problem. the question about the water pump (engine). when doing just some quick troubleshooting before changing the seawater pump, i pulled the engine waterpump off to check the impellers ( a real problem with automotive, no leaks but no impellers on water pump.) everything was fine, so i suspected the seawater pump.

i was also wondernig how the manifolds could cause a water flow problem unless clogged up, well when i hook the water hose up it flows just fine, because of the pressure, which also would mean no clogs. now that the seawater pump was changed, sunday i started the boat but like i said before, the tub i used wasnt high enough to fill all the ports on the foot. today i got a tub large enough to fill the ports and the engine flow perfectly, just as it should. i know that the manifold and riser should still be changed but it turns out the main problems were: originally a bad seawater pump, then a tub that wasnt large enough to cover water pick up ports. the water in the oil was caused by me (the bonehead) not taking the plug out and rain water entering the engine. the next actions will be flushing the oil and changing the manifold and riser out of good measure.

Cost you time, but glad you got out cheap. I know the manifold/risers will cost bucks, but believe me it will be well worth changing them out now then down the road while you rebuild the engine due to water intrusion from them.

You guys are just awsome ! :grouphug

i agree with that, you guys are great. thanks again for all the help. hope to see yall on the water very soon.
