I replaced the cooler and flushed it three times as recommended by Fantasic Finishes and others. I took it out yesterday and it ran great and no water in the fluid.
Thanks for the good advice Tom |

PSA: I have used diesel fuel with good results for flushing the gear. Its cheap, easy to work with and does a good job of cleaning out the nooks and crannies. It has enough lubrication to not harm bearings while running unloaded. I use the gears own pump and a bucket. Coolers are cheap, just change it and quit wondering.

My Trans fluid looked just like that on my first trip last year. I was already to buy a new cooler, but someone suggested doing a few fluid changes before placing the order. Wouldn't you guess it cleared up. Now I'm not saying you'll be as lucky, but some condensation can cause a milk shake and it takes more then 1 change to get all the water out.
Good luck |

Transmission guys will tell you that you must take the transmission apart. Water gets trapped in the reverse piston and for forward piston. Im not convinced that it cant be flushed by changing it multi times though. I will tell you however that if the surfaces have any rust it will wear out the piston seal and also make movement difficult.
You may want to pull it off and install seal kit and clean it out properly. |

My first thought as well. The trans cooler being thin walled copper, it doesn't take much to freeze it. I suggest pulling it and do a pressure test on it. |

Any chance it didn't get drained during winterization?

Dang - I just replaced the cooler 2 years ago. And the bilge had very little water in it.

Water doesn't run through the transmission. It can only come in through the dipstick, breather or cooler. Unless your bilge had a lot of water in it, I'm betting on the latter.

I took my boat out today for the first run of the year. After unloading and riding around a little bit (lessthan 10 minutes) ) I kept stopping to check the fuel,line connections I just replaced. I decided to check the transmission fluid as there was an unusual sound coming from that area. The fluid had water in it. I road around for about 1 hour (and I did not hear the sound again) and the transmission fluid level did not change, there was no transmission fluid in the bilge and the boat worked fine. When I got home I removed the fluid .
 . The transmission was rebuilt about 18 months ago by Eric's old shop in Ohio. I am guessing one of my seals is leaking - your thoughts, suggestions or tests would be appreciated. Thanks Tom |
