Re: Silicone BT seals

Hi Mike,

I’m very methodical in my checks before sailing away ... retired airline pilot.. and it involves all systems internally, in the engine room and on deck. Covers all bases. 

Takes 10 minutes

JP, I think this is good advice. Especially because it's the foam seals that really keep the water out, not the vertical shaft seal. Do you have a foolproof method to remember to put the pin in place while at sea/underway? That's the only risk I my opinion.

FWIW... my seals are good for years. 

My trick is to release the pin whenever we are in a harbour/ anchorage. The pin is in only during offshore passages. Saves the crush on the seals

To all,


We had constant issues with our bow thruster and a small amount of water coming in. I followed the directions for the service to the letter and for a few months it would be dry. Then, slowly the drips began and over time would slowly get worse. I found myself having to change the seals every 6-months to a year.


I changed Jose’s seals in Galapagos before crossing tp French Polynesia. So far, the area is bone dry! 6 months now.



With best regards,

Hello All, 
I am ordering 10 pr (min order size) of the silicone BT seals pioneered by Jose Venegas a while back. Although I have not used them myself they are apparently quite effective and I am anxious to install them on Liesse (if I ever manage to see her again).   I will have an extra 4 pr at USD 81.00/pr. plus shipping for anyone that would like a pair or two.  If you have specific questions about them I would refer you to the archives.  Private message me if you are interested.  Thanks. 
Best regards, 
David Bruce
