I thought if i had pee stream the engine would be getting cooled just fine :whack: if i find the thermostat...what am i looking for? Do i have take off the part where the spark plugs go? the plugs didn't look like they had anything foreign, but one was black looking...the part i have arrowed is what was HOT including the plugs...what is that called? Am i supposed to remove those bolts to get to the thermostat?

bump for my boy jtexas...come back potna... thanks!!!! I was hesitent to remove those bolts and check otuthe thermostat because then I would need a new gasket right? i wanted to make sure i get the gasket first, thanks bud

well, you've already gone farther than I would have without a manual.

yup, the thermostat is at the top under the cylinder head cover, which is held on by those 14 bolts right there. It's unclear but appears that maybe the cylinder head is retained by the same bolts. For sure you'll need a head cover gasket, maybe (probably) a head gasket as well. And the torque values.

I guess we're pretty convinced that it's overheating in spite of good water pump function? There are ways to check the temp - infrared temp gun, or you could get some thermomelt sticks at www.ishopmarine.com - course you don't really know the proper operating temp. I'd go with 163º, if it melts, it's too hot.

post pics when ya get the head off, this should be interesting.

i don't have a manual jtexas...but i do use those schematics from brownspoint...that's where i am finding out where the parts are...its shows it in good detail...thanks for your help..i am 99% sure it's overheating despite the water pump working...because smoking and THAT hot is not right...do i really need to test the temp to find out? I mean...it was HOTT i've already established it's "over" heating...thanks for your time man

nah, no need to test, just wanted to be sure you were convinced.

Hopefully it'll be obvious, some kind of blockage or something. Put the stat in a pan of water on the stove with a cooking thermometer.

hey they got schematics, that's something

you can prolly already tell im a beginner at all this...so i won't apologize LOL, but what is the point of putting the t-stat into the boiling water...what am i looking for? I think I am going to just remove the cover and tstat, to check if that's the problem before i order the gasket..that way if the tstat is bad i can order it all at the same time..what ya think? Im gonna go remove the cylinder cover now...I hope i don't need the cylinder head gasket..because it's $45 just for the gasket :\

OMG jtexas..im so pissed right now i could probably kill someone...i tried to unbolt the cylinder cover...ALL the bolts are stripped...I could only manage to loosen 1 out of the 14...I have a feeling im into a BIG problem now..what in the world do i do now? i was thinking of spraying some wd40 on the bolts/washer area to hopefully loosen them up a little..whatcha think man? *sighs*

Didn't your momma ever make thermostat soup?

watch the stat and check the temp when it starts to open. The correct temp should be stamped on the stat somewhere or if it's not, 123º should be about right. This is how you'll know if the stat caused the overheat.

There is probably somewhere in a hardware store, a pair of vise-grips that will do the job on those head bolts.

Or, got a dremel? if you don't you gotta get one - I don't know who invented the dremel tool, but his birthday ought to be a national holiday. Anyway, what ya might do is, put a coarse sanding barrel on there and go to town on those head bolts, square 'em off in some fashion that lets you get a tool on 'em. Wouldn't recommend trying to make 'em back into hex heads - requires too much precision.

I just made that up - but I'd sure give it shot, before trying to drill 'em out.

Tell the truth....you weren't using an adjustable crescent wrench now were ya? Or an SAE socket on a metric bolt head? Personally I favor box-end wrenches - I have a hard time with sockets sometimes too.

Look for something called "PB Blaster" in a spray can, see if you can get it to penetrate those head bolts.

Anybody reading this who ever worked on old boat motors is laughing with ya, not at ya.

i got em off!!! i think i was using the wrong socket like what u said metric standard hooplah...here is some pics of the massacre...

see pics above...but i did put the t-stat in water and just like you said it started opening up at about 125*...that is actually kind of bad news i was hoping it was broken so i knew what was wrong...NOWWWW what does one do? *sighs*

that stat looks pretty nasty, I guess it opened on up all the way? Corrosion or anything partially blocking the opening?

It's a shame suzuki don't let you pull the head cover without pulling the head - you could test run it without the thermostat. That'd cost ya an extra head gasket.

So, pump is pumping, telltale is peeing, that just leaves three possibilities; either something's keeping water out of the top of the head cover, or something is blocking it from exiting through the lower unit, or else combustion chamber temps are higher than normal and boiling the water.

If that motor's like others, cooling water collects in the midsection (keeps the exhaust housing from burning up) before flowing out down through the L/U - like maybe a row of holes above the antiventilation plate.

Curious, where is the tap for the telltale hose? Is it low on the water jacket, or up near the top? Or somewhere else altogether?

Some causes of abnormally high combustion temps...inadequate oiling, preignition, lean mixture (more air less fuel than normal). Probably some other causes I didn't think of.

Can you see any scoring on the cylinder walls?

ok jtexas...would scoring on the walls be groves? I can't see any and they feel pretty smooth...maybe not perfectly smooth but smooth...I am ordering all the parts, both gaskets, and the t-stat and installing them as soon as i get them..should be monday/tuesday...what is "thetap" for the pee stream? the water actually comes out right below the actual engine part...not sure what your asking though...let me know if you want me to take a detailed picture of my engine and you can show me the part your talking about...thanks for your time again bud, eventually you and i both can rest assured that this stupid thing will run!!!!!!

yeah, grooves.

the pee stream tap, where it originates, if it's tapped into the cylinder head, or just branches off the water tube. It was just a hunch, not worth worrying about.

at this point...ANYTHING is worth worrying about...i have got to find a fix sooon...i guess ill just report back after i get the parts next week...

well, ok then, I didn't want to overcomplicate it, but there was this service bulletin I remembered.......

thanks alot for confusing the [censored] outta me...preciate it LOL

i got my parts in...after more inspection i guess i am screwed...the inside of the walls where the piston is..on one of them it is scarred up on half of the circle... depending on how much that costs to repair might just have to cut my loses and just be out $1,500 instead of MORE...were trying to clean the cyliner headareas where the gaskets go so they are smooth and remove old gasket material...ill let you know if it even starts after this...will it with scratched walls?

ok...my man jtexas...got everything installed and cleaned up...motor started up...NO PEE STREAM? it looked like it was going to start peeing, spurted out a few drops, then stopped...what do you suggest now? Thinking of dropping the lower unit again and checkin it out? thanks bud

scored cylinders usually means some compression loss.

I'm thinking bout your difficulty with the pee stream - don't they have a pill for that now?

sorry, couldn't resist...........

so no ideas?

let's recap.

No pee stream -- new impeller fixed that, but the engine heated up -- new head gasket, and the pee is gone.

could be, you just need to get a mo betta mind than mine in on it. Have you tried the suzuki forum over on http://forums.iboats.com ?

have to give it some thought. I'll be camped on Fairfield till Saturday......good luck.

basically, yes thats it...had all those problems thought it was carb, fixed that...then no pee stream...fixed impeller and then had pee stream bu tsmoking cylinder head...fixed gasket n tstat and now...no pee-stream!!!

is there anything on this pic i should check? is there a way to remove or check flow of that rubbe tube part#1-2? any suggestions what to look for now...i remember hearing someone talking about the "flush" bolt thing on the side of the engine can i do something with that to help troubleshoot? thanks

ok jtexas...yesterday i took down the lower unit and got my garden hose sprayer and sprayed up the tube and it was shooting awesome out the peehole..so for sure that tube isn't clogged...today...i took out impeller...put it back in clockwise like shown in this pic of it, and i then had a WEAK stream spraying in spurts, and i did the finger cylinder test and felt it getting hot so i shut her down...but none the less...a stream...wutcha think? i think i *might* know what's wrong if you don't have any ideas...I want you to look at the drawing on the right side..see the parts labeled #5 "repair kit" the 2 ring looking things above the actual impeller...those aren't in my housing if u look at my actual pic, and I couldn't find that "repair kit" so i got the impeller and gasket seperate...Do you think that's the problem..IT HAS TO BE...next question...how i get them there parts?!?!?!???

switched the impeller, just didn'tlook right clockwise theway that little area is to shoot itup...now have a strong pee-stream...I am haveing to order another clutch coupler though mines been giving me problems..i can still start it without that right? I did today and the prop was spinning?
