Cruncher....have you checked the TNT fluid level in the reservoir lately? If it's good, chances are ya' got a plugged in one of the trim lines. May need a flushing. I got the same TNT unit on my 84' 50hp Johnny.<br /><br />Don't know about the rattle....they can be a killer to find. What ya' might do is get a short stick to use as a sounding rod. A metal rod works better. While the engine is running, put one end of the sounding rod to various places on the block and see if you can pinpoint the source o the rattle.

Thanks for the reply OBJ, I've already taken off the left ram. and when I worked it in & out a few times,it all of a sudden would go all the way down???...but when I reinstalled it,I have the same problem???....I left it unhooked to see what it would do,when I ran the trim up & down....nothing????...but soon it would not go all the way down again???

Cruncher,<br />I had a rattle that was driving me crazy. I thought a rod was going bad or something like that.<br />It turned out to be a latch on the engine cover was rattleing. A piece of folded paper between the latch and engine housing stopped the noise.<br />Yes, I did tighten the latch but it still rattled under power, sounding like internal engine trouble.

Cruncher.....There is a way to fill and vent the system that you need to follow.<br /><br />Raise the engine all the way UP. Check the reservoir level and top off if needed. Cycle the engine up and down 4 to 5 times and leave it up and recheck the level. Do this until the level stays the same. Correct level is at the bottom of the reservoir fill plug hole.<br /><br />Cycling the engine up and down purges the system of air that is released when the plug hole is opened.
