milky cylinder

Re: milky cylinder

Somewhere in the neighbor hood of 150lbs. That's just a rough estimate. I can lift the assembled power head myself, but trying to maneuver it is a different story. I've never used a lifting eye. I usually take a rope or nylon strap and wrap it around a couple of points on the block and a hydraulic motor hoist. You could probably rig up a hoist with 2X4's or something similar and a come along.

Re: milky cylinder

i thought about that, i was just worried about breaking something, carbs, elctrical, etc.

Re: milky cylinder

got the motor out, couldnt find a liftinf eye so just muscled it out myself, dodnt see any cracks, and really didnt see any breaks in the exhaust gasket, did have some burnt carbon on it so I'm hoping its there

Re: milky cylinder

It shouldn't have any burnt carbon on the sealing surface of the gasket. That's a sign of a leak. Sounds like you're on the right track. Did you notice any water inside the exhaust cavity?

Re: milky cylinder

yes it was full at the bottom

Re: milky cylinder

does anyone know the tork of the 4 cylinder head cover bolts? the manual just says "tighten securley"

Re: milky cylinder

I believe they're 1/4 20 bolts. Standard torque for this size bolt is 70 INCH pounds, or just under 6 FOOT pounds.

Re: milky cylinder

ha! I guessed right!!

Re: milky cylinder

ok, got it back together and torked, I dont suppose there's any way to check for leaks BEFORE it goes back in the boat?

Re: milky cylinder

I guess you could built a stand out of 2X4's to secure the motor. Next problem would be getting water to the block. Isn't the water pump from the lower unit connected with a hose to the power head on the L-Drive? If so, can you rig up an adapter so your garden hose can be hooked up? If you can solve the mounting and water supply problems, you should be good to go. Be careful not to rev the motor too much as it doesn't have a load on it. Very easy to over rev it.

Re: milky cylinder

i got the motor in and running but its spraying, not leaking, water between the head and block, i took the head back off and there was a lump of permatex around the bolt hole from when i used it on the cylinder head cover, could that cause it?

Re: milky cylinder

It's hard to say, but I kind of doubt it. Did you use a new head gasket and torque the head bolts in the proper sequence? The head is not that thick and easy to bend, so proper torque pattern is important. 225 inch pounds or about 19 ft LBS.

Re: milky cylinder

yes i did, the way it wa spraying was really odd, i guess I'll try and clean everything and give it another shot? i was really careful when i put it on

Re: milky cylinder

Take a really close look at the head gasket to make sure it looks OK. Maybe you had a defective one?? Make sure the head gasket doesn't slip out of place when you install it. Access to the block on the L-Drive is not as good as a regular outboard so it's a little harder to see sometimes. Take the head, place a couple of head bolts and stick them through the head at each end. Then place the head gasket on the head. The bolts will help hold the gasket in place. When tightening the head bolts down, do it in two or three steps. First step tighten all the bolts to 100 inch pounds in the proper sequence. Do the same sequence again, only tighten to 175 inch pounds. Do this in steps until you reach the proper torque.

Re: milky cylinder

i did all that, i put several bolts in so i know it was lined up. they only thing out of the ordinary i did was put the cylinder cover on first, with permatex, and lightly bolt it to the block to dry, then put the head gasket on the next day, there was a pretty good "lump" of sealant around one of the bolts right about where it was leaking when i pulled the head off today

 

[pnwboat]

Re: milky cylinder

Then I would say that the lump of dried permatex was probably the culprit. Doesn't take much to prevent a good seal. By the way, did you have much trouble dropping the power head back on?

 

[bayliner12]

Re: milky cylinder

i did it by myself so it was a little challenging, once i turned the fly wheel it dropped right on

 

[bayliner12]

Re: milky cylinder

cleaned it up and put the head back on, not spraying but still leaking, now what??

 

[bayliner12]

Re: milky cylinder

just checked compressio, 135 all cylinders and no water in the cyliders so we know the steel part of the gasket is holding...I'm stumped

Re: milky cylinder

post a few pics of the leak maybe a vid.... was the head checked for flatness with a machinst straight edge?
