the bow thruster batteries are 2 x 50 Ah Optima. model 34R, (Hem | OPTIMABATTERIES
) "Made in USA". Previous owner told me he never changed them and believed they are the original installation
from 12 years ago. Still work fine.the bow thruster is also original and the label says "Super Power series 100 - 12V, Max Power-F06210 Cannes Mandelieu "
Sorry, i guess that means that Jeanneau
was not using Vetus in 2004.
