Heres one to wrap your minds around. I have a 94 38 Fountain Fever Bravos 502/465hp. During a routine gear oil change, (I have done it a million times) I pump the gear oil from the bottom of the drive into the bottle in the boat. So i did and i go to start the boat and BOOM BANG CLANG...So long story short we pull the drive and the oil went into the shift cable housing instead of the upper case. I smoked the two bearings on the uppercase luckily no gear or case damage. Am I the only retard that can blow a drive on a trailer or has this happended to any of you guys. My mechanic who has been working on boats before there was water never heard of such a thing??

Well just A long shot here, But I was told you should not pump the drive oil in on cold days or pump it up with real cold oil in you new bottle, And if you do pump while cold you should pump real slow while pumping, Do not aply any pressure with the pump or you will over pressureize the drive and blow out seals. Just so you know your drive only builds around 7 psi oil pressure while in use. And the part of blowing it on the trailer well any thing can happen, But the good news is I bet it was a lot easyr to deal with a broken drive on the trailer then out on the water with no one around to help. Good luck with it.

If the cap was on the reservoir bottle, I could see this happening. Air pocket and too much pressure and it pushed out the back cover gasket and leaked into the shift linkage/bellow.

You got any suggestions as to why my dipstick keeps popping up on big passes? I have a 540 dart motor setup and it is blown, and have a puke tank setup on top. Seems kinda odd that the oil in the pan with no pressure behind it can raise the stick out??

Its not a huge deal, but the boat does require a little wipe down in the bilge after I'm done?

The only reason the stick comes out is because there IS pressure in the pan . I would check the lines going to the puke tank and make sure they are clean.

I would do a cylinder leakage test sounds like you may have another issue.

sounds like to much crank case preasure. if you don't have a whole in your piston than you need to ventalate your case better.
