Water in V Drive?

[Eastern shore wake]

Hi, I have a 2010 RZ4 with the 409 PCM. Has about 350 hours on it. Took it in a couple of weeks ago to local inboard dealer (no Tige dealers near me). They are doing winterization and asked them to do some other maintenance including changing oil on V drive. Got a call this morning from them saying oil in v drive is milky white and there is water getting into it somehow. They said only way to diagnose is to pull v drive and "break it down". I asked how much that would be. They said they needed to figure out an estimate as there was alot of work involved (scary). Wanted to see if anyone here had any ideas as to how water may be getting in and if there were any possibilities which could be checked quickly and without pulling the V drive. Thanks!!

Not true at all. There is a cross over tube inside the V drive where the cooling water passes thru. Where the caps install on each end there are 2 O-rings on each side. One to seal the inside and one for the outside. If one of those O-rings cuts it lets water into the Vdrive. I'd give you an 80%+ chance that is where your problem lies. Very serviceable by just removing the water hoses and the caps without even considering removal of the Vdrive. Any decent inboard dealer should be familiar with that Vdrive(very common set up) and should have checked the O-rings before saying anything about removing the Vdrive. You could literally have both caps off and the O-rings checked in less than 5 minutes.

Considering their diagnosis i'd strongly consider a conversation that goes something like " thank you for notifying me of the problem. Plese don't do anything further with my boat, I will be on my way to pick it up."

I have a 2011 rz2 with pcm 343 and pcm v drive. Fluid is milky but not really overfull. Are there orings on the elbows for the water hoses that are threaded into the v drive?

Internally leaking oil cooler for the v-drive could be culprit as well.
