need help
 

need help I don't have water in oil but motor is hard to turn over. headers are 99s I have not tested yet. looking at a place to start. the motor is a stock 500efi with 300hrs .One tail pipe looks like it is blowing out mud and has for a while can someone help thanks

mud??????????????

no cooling problem water is deep at my pier should not be sucking up any stuff

check your timing

Need more information.Hard to turn over?What does that mean?Does it crank but just wont fire or does it just go "clunk" when turning the ignition.

its seems like it might be getting water in one side of the motor its very wierd and only on one motor

did you pull the plugs? That would tell you if you are getting water in the cylinders.

yes looks like its burning rich

no water

sounds like your timing is off some how. check to see if the distributor is loose

how many hours should you go with springs . Also what would be a good head as an up grade to boost power with a cam

First of all you need to determine what's going on with your engine before you think about upgrades or performance mods.300 hundred hours on springs is really not that much depending on how the motor was treated,maintence and the environment is has been used.If this boat only saw 6k rpm's in the life of the motor springs and pistion rings would be something to look at. Did you do a compression and leak down test? What does blowing out "mud" mean.Would like to help you out dude but ya might want to be more specific.

What color is this mud and has your oil level changed? If the mud looks like a nice fluffy chocolate milkshake then you are pumping oil out the exhaust somehow.. I had a leak develop in the oil cooler which promptly made 5 quarts of oil "disappear"

Hopefully this isn't your problem..

working on the problem tonight I was thinking hydro lock motor makes a half a turn and thats it starting at the headers tonight and working my way down any ideas thanks for any ideas
