    New to Yamaha. Newbie question.

    Ok bear with me here. I picked up a triton a couple weeks ago and it has a v4 155 Yamaha on it. I have serviced pretty much everything but the lower unit. What weight gear oil does it take?The serial number is: 6e5x731892 if its needed. Thanks for any help.

    I'd use Amsoil Universal Synthetic gear lube.
