Re: did I suck something up to stall out ????

If the motor still seems to be locked up I would tilt it up as far as it will go and put a couple of tablespoons of Marvel Mystery oil in each cylinder so that it penetrates to the rings. That stuff works wonders (available at most auto parts stores). Let that sit for a couple of days then take a socket wrench with a socket to the top of the crankshaft and put some muscle to it. <br /><br />The black grease that you described on the inside of the head is normal and is carbon with some oil from the fuel mix.

Re: did I suck something up to stall out ????

Again to all of the experts, i have made some progress. The Flywheel will turn nicely now thanks to all of you with all of your help. I Sprayed the WD40 in the cylinders and put some muscle into the flywheel nut and to them to turn. Now i can spin the flywheel by using my hands and very little effort. I am going to put the Lower unit back in right now. I greeced the Drive shaft. Is there anything else i need to do the the lower unit before putting it back in? I also had a question do i need to do anything (besides replace the head gaskets) to the power head before i try and start her up again. Thanks for all of the quick responces.

Make sure there torqued per specs and tightened in the right order. Manual should show which bolt to start with and end with. <br /><br />Glad to hear things are goin good. Another thing... If the head is still off I would rotate it a few times and look at the movement of the pistons. Make sure there movin freely and not getting hung up anywhere

I don't remember if you replaced the water pump but if not now is the time to do it.

Re: did I suck something up to stall out ????

I checked out the Water pump and took it apart. everything looked great i threw a rebuild kit on it and now all i need is to get the motor fired up. i checked out the Clymers manual and got the specs for the cylinder head torques. tomorrow i will purchase another Torque wrench seeing as mine is back home and hopefully i will be able to fire the boat up. I put the WD40 in the cylinders to loosen them up/is this going to effect the engine in any way? i also was wondering if rebuilding the carbs is a project to big for a new bee to preform. I would have looked into it if there was so good info in this clymers but everything seems to be so vague and not very specific. Any imput from you guys is helpful to me.

Re: did I suck something up to stall out ????

Another quick question,I am going to buy some new head gaskets for my Motor and i was wondering what the difference was between regular head gaskets and low compression head gaskets and which would be better for my Engine, <br /><br />(1982 Rude Cross flow V4 115hp)

 

[djzyla1980]

Re: did I suck something up to stall out ????

Not to sure on the head gasket difference but I believe it implies exactly what they say. Low compresion head gaskets. You can expect a lower reading with those. I would stick with the regulars. But thats just me <br /><br />Rebuilding the carbs is easy to do... even for a newbe. Pay close attention to the pics in manual when assembling and make sure you soak, clean and blow them out real good. It's an easy thing to do and worth it if you don't know the last time it was done.<br /><br />WD40 shouldn't hurt anything..... might smoke a bit more when it fires till it burns it out.

Re: did I suck something up to stall out ????

Experts, got my tourque Wrench today, and started on my on going project. i looked up the torq specs and it was in the clymers manual. Then only gave the specs in (in lbs) and my tourque wrench is (ft lbs) need some help finding the right setting so i can do this on right. <br /><br />Also does anyone order parts from iboats if so about how long does shipping cost and is this the best way to buy head gaskets. Thanks again

Re: did I suck something up to stall out ????

Ok i got the right torque specs on the internet, and now all i am waiting on is getting the Gaskets in from the dealership. Is is a good idea to put gasket sealant on them. Thanks almost done with this one. Also i just aquired the boat and motor from a friend who says he ran it in his back yard about 2 times a month for the past 3 years and has never taken it on the water on that time accept to test drive it with me. Is there anything i shold be looking for maintence wise before i take it on the water. Thanks again for all of the quick responces.

Re: did I suck something up to stall out ????

I believe if like any kind of composite gasket you do not use gasket sealer on them. <br /><br />Impellor, and LU lube is the first I'd do to it.

Re: did I suck something up to stall out ????

Thanks Dave, i used it on the impeller and the LU. now just waiting on the good old US Postal service

Re: did I suck something up to stall out ????

I'm glad you got the powerhead unstuck. I'm concerned though that you really haven't found what caused the problem. The WD40 & wrench-on-the-flywheel-nut trick is generally reserved for a motor that has sat a long time and the rings are stuck in the cylinders. "Seized with age". Your motor was not sitting, it was running. And it sure sounds like a piston was stuck. That's why the flywheel would only move a little bit back and forth - there's a little play in the crank/rods/pistons (supposed to be) that'll let the flywheel "jiggle" even though the pistons don't budge in their cyinders. Something caused a piston to stick WHILE THE MOTOR WAS RUNNING. Often that's extreme heat in one or more cylinders. Or water in a cylinder (hydrolock). Both are potentially very expensive. <br />Before you go zooming around any distance from the dock you should do a couple things. Get a compression tester and check compression on all cylinders. They should be above 100lbs (more compression is better) and be within 10 lbs of each other (less variation is better). Any suspicious cylinders? Next, idle the motor on the "Mickey Mouse" ears and pull plug wires one at a time, putting them back each time. Use a rubber-handled pliers so you don't get shocked. Does pulling each wire affect the idle the same way? You are killing cylinders one at a time, so if one is already not firing it will have no affect. All OK? Spend your first half hour on the water within paddling distance of the dock, and really listen to the motor run - see if it sounds any different after it gets warmed up (10-15 minutes). If all is well and you cruise around and have fun, take the time to pull the spark plugs when you get home and look them over. They should all look exactly the same.<br />I really would rebuild the carbs if I were you. Good luck!

Re: did I suck something up to stall out ????

I was thinking the same thing itstippy Just wonderin about the head gasket. It sounded to me like there was water getting in the cylinder. <br /><br /> "i didnt find any scoring infact the cylinders looked very smoot and clean, except or the lower one on the starter motor side. there was a little bit of water at the bottom but it didnt look like a lot. I bought a clymers manual before I even took to boat out, and read threw it today to see what the water might indicated it didnt say anything about it not even in the cleaning and inspection section."

Re: did I suck something up to stall out ????

First off, I want to thank itstippy for the very informative memo. I bought a compression check and feel pretty good about doing the check on my own from reading all the other imputs from this page. I am still awaiting the gaskets via mail so i cannot preform the check just yet. I also agree even though i do not know alot about motors i am still stunned that the engine would lock up just like that. i did find some water in the lower cylinder on the starter side and feel like that is the cause to all my problems, however i looked at the head gasket and it seemed to be intact and in prettg good condition, like i said earlier i dont know how else water could have gotten into the cylinder, and maybe i am over looking something in the head gasket. Second i would like to thank dave for all the replies and helping me keep my project on the right track. I dont know what else to tell you accept that the lower cylinder had water in it, and it was not an awful lot but enough to say fill a small soda cap. well thanks for all the comments and i will probably be needing some more help on this one. Also is it a good idea on holding off on the carb rebuild until i find out this problem?

 

[Solittle]

Re: did I suck something up to stall out ????

You may want to hold off on the carbs until after the compression check if there is a possibility that you would not fix the engine if the compression check shows a major problem. If you are committed go ahead. They are not a big deal as others have said.<br /><br />I assume you that the shop and parts manual.

Re: did I suck something up to stall out ????

Well back again. Just got off of a 24 hour watch for the navy and dead tired, however we are getting ready to go back out to sea and today is one of those get everything done days. the head Gaskets came in yesterday and i could be happier to put them on. I just put both gaskets on and turned the fly wheel by hand and by starter and it is still turning nicely. (thanks for the help on that one experts) now that i put the right torque settings on this beast i hooked up all of the spart plugs wires ext.. and pumped the gas blub and tried to give old girl a start. The problem now is the starter has enough juice to turn the wheel but now she will turn over and then all i hear is a grouling noise from under teh fly wheel. When i the flywheel stops moving the growling starts. and clues on what my next step is on this problem child.

Re: did I suck something up to stall out ????

To add to this topic my wife just woke up and came to give me a hand. I let her start the motor and then went to the back of the boat to listen and inspect my self. I looked at the engine as she started it up and noticed that the noice quite possibly could be comming from the starter is there any way to check this. I know its early but i appreciate any advice anyone can give me. thanks

 

[Aquasport19.6]

Re: did I suck something up to stall out ????

yet another post. i took the time to take the starter apart and see what was up just incase that noise was the starter itself. looked inside once i took it apart i smelled like burnt electric but no visible sign of anything burnd is there a way to test and see if teh stater is good from the home.

 

[djzyla1980]

Re: did I suck something up to stall out ????

What kind of noise are you hearin...<br /><br />I basically test the starter this way.... Turn the key... if it turns the motor over with out slip at the end.. (meaning it will turn the engine enough to start) then the next thing is when the starter gets warm. Most starters (auto ext...) Loose there effiecency when warm... or when they heat up. If it's startin your motor or you can crank it awhile and it turns the flywheel... cold or warm I wouldn't worry to much about it. If it does however start to turn the flywheel like your battery is low... but it isn't, Then more then likely the starters goin.<br /><br />Depends on the noise your hearin....Did you ever get it to run??? <br /><br />It is quite possible that while tryin to start the motor when it was locked up/locking up caused to much strain on the starter. There meant to turn a flywheel that moves... and not getting caught up.
