bravo 3 new prop shaft seals leaking
 
Took my talari on the water yesterday for the first time since having my prop shaft seals replaced. I noticed this morning that there is a puddle of drive unit oil under the skeg. it's leaking behind the rear prop and has about a one foot diameter puddle on the floor. I really don't think new seals should leak, especially this bad. Any ideas? This thing is turning out to be a nightmare

There is a possibility you may have got fishing string tangled in there. My dads out drive drained last season because of that...

It's a possibility. I need to pull the props off and look

Did the fishing line ruin the seals?

Yeah. I don't know how it gets into the places it did but the string was on the oil side of the seal wadded up. Basically tore seal up.

Oh no. I just had new seals put on this thing too. I've been doing a lot of searching for info on this and found a lot of instances where new seals will leak some until they are run in and seated. If I don't find any fishing line, I guess I can hope that this is the case

Paul ,
There is no reason for the seal to leak unless one of the following happens:
The fishing line around shaft , as has already been stated
A groove in the prop shaft itself
A bent prop shaft
A bad seal
Or a bad install of the seal
What does the marine tech that did your reseal say?
Ask him to pressure/vacuum test the drive , if it doesn't hold pressure/vacuum , then it is going to get water in the drive
Water in drive = bad things happen quickly

Larry, haven't talked to the shop that replaced my seal yet, but I do remember him saying he had a heck if a time getting it on there. Kinda raised my eyebrows when I heard that. I'm gonna pull the props off later this morning. If there's no fishing line, then it could be a bad install or one of the other things you mentioned

I'll post my findings. This thing is really turning into a money pit. Found several other things wrong, too, that need attention on top of the seal leak
