Bass,
When you hauled it did you drain the line. Is it possible you had water in the line which froze up?

Try a small wire up the pee hole while running. Quickly! Don't block the flow for long. Just enough to check for a blockage. Sand is a big culprit with this issue or calcified salt can build up too. My thermostats were white at the end of last year.
Good luck.

The Poppit Valve is a very common issue with outboards. Like a thermostat, it regulates the water flow coming out the pisser to keep the engine at the proper running temps. It closes and restricts water if the engine is too cold or opens up when the engine gets hot. It could cause the issue you are having if it's clogged and could make your engine run hot as well....
A typical symptom of a bad Poppit Valve is the engine running hot at lower RPMs and fine at higher RPMS
I would check and clear the lines first as mentioned above and if that does not resolve your issue I would look at the Poppit Valve.

thanks guys , was checking to see if maybe something i didn't think of , but all of you came to same conculsions i did , when running i did try a small wire through the pee hole....didn't see nothing or feel anything ...no help on water flow , i did pull the thermostats and they looked good. but replaced with new as i figured it was time anyway ....the poppet valve i had parts on order to rebuild that , which just came in yestarday ...that will be getting done tomorrow , i haven't started since the thermos have been put it , i figured ill replace the poppet and then check it , it was over heating thus causing the alarm to sound be cause it wasn't getting enough water !!
with all this being said , the only other thing i was wondering the connector piece from the copper water pipe to the water impellar housing has o rings in there how much of a big deal is it if those are not seated properly , i mean i should just replace but just wondering if it make a big deal losing water pressure!

Look ok to me. Right back in! :rolleyes: :D
To be honest mine probably looks exactly the same way. I didn't change mine last year and can't find the chapter in the Seloc manual. Nothing on youtube either that covers my engine (1993 yamaha 200hp). Will keep digging.
Hope the valve replacement does the trick!

Try the wire first. Had a Suski that always had to be poked.

This is what I found this weekend when finishing the impeller... Time to pull the powerhead: the copper water tube going through the shaft wasn't sealed all that well and wore a hole through it... $27 part- :mad:

That sux!! What year engine?
Found this link for instructions on where and how to replace the Poppet valve on a OX66 Yamaha. Figuring (hoping) my 93 is similar. Will find out in a couple weeks I guess.

if you are referring to me , on the year for my engine its a 1996 merc efi , it wasnt bad at all to replace. had to remove half the mid cowl and it was right there! if the bolt wasnt so long wouldnt of even had to remove the cowl. but its done now and i just need to start to see if it fixed the problem.
as for d-fish , i cant believe the copper pipe wore out like that ! my pipe looks ok but the o-rings in the coupling are pretty bad i might replace those also just to get them done
i went on ebay and bought a repair manual for my engine ! its great and very detailed on how to repair assemble /disassemble but it doesnt tell you how to diagnose lol ! i just suspect or ask what it could be then refer back to manual to repair , even if it doesnt need repair but looks to be in need of repair soon i just do it and get it done anyway !!!
good luck fin you might find its not to bad !!!

i forgot to mention how much money i saved doing most of my own stuff! when i first bought a boat it was an 83 renkin i was fixing up and the engine needed some work, it was an i/o so i called a mechanic, after 3 hours and saying this and that nothing was fixed and he wanted three hours pay ! i got pissed off gave him his money and told him never to come back. so i sold the boat and said the hell with that. went an bought my proline ...i was on the delaware river and my alt went on me. called seatow to haul me back ...got to my marina and started calling people to come look at it (not knowing it was my alt)after calling so many people and having them tell me its like 90-105 an hour but couldnt tell me how many hours it would take to figure the problem out ...i got even more mad !! a good mechanic should be able to diagnose in an hour then how ever many minutes to hrs to fix ...i bought the manual and started doin everything myself! come on forums to ask questions from knowledgable people like yourselves what it could be then work from there ...!! saved prob about 5000.00 or better on repair labor so far !!

Exactly, it's all about saving when you can. Was quoted over a grand for this part replacement:eek: One quite helpful thing I found is to get the seloc online manual for your specific engine it's like $30 for three years and always at your fingertips when you save as reading material- that way if you're for instance at work and want to read up... No need to bust out the book, computer,tablet,smart phone- all work. Best of luck guys, not trying to hijack anything just another one of those things within the realm. Splashtime is coming up fast!!

update:.......so after replacing the thermos and the poppet , started it on sat ....put the muffs on and it was a very light stream ....so i cupped the muffs and got a very good result , it was peeing like a race horse , which didnt happen before i replaced the parts and cuppping the muffs ....the year before last i replaced the impellar and no need to cup the muffs so im gonna go ahead and replace the impellar again just to be on the safe side ....i have to pull down the unit anyway to replace the speedo connector i had purchased ....so it seems as if the poppet and thermos were the prob !!
