So I get back from the Texas Jam, boat went straight to the stall. I pull it out today after work, we all load up, back the boat in the water, I put it in reverse... NOTHING. Going Nowhere!

I'm freaking out. Prop is good. Check levels. Really low tranny fluid. Run to the gas station close by and buy the only thing they have, plain ole Pennzoil ATF fluid. Fill up. Doesn't work. Upon further inspection, find three bolts and three nuts in the hull and realized the shaft had separated after the bolts fell out... Put those three bolts back in, tightened em down, and on our way we went. Mainly tied up today but tomorrow we will be doing more driving/surfing...

So two questions..
Do I need to drain that plain tranny oil out and get the dextron III stuff, immediately??? (Id like to spend tomorrow on the water if I can and replace the fluid on Sunday...)

Also, are those three bolts all I need or am I missing more?

Thanks,
Taylor
