New (to me) 174 SF Exhaust Manifold Drain?-gctid820027

[CanuckJack]

Hi all, my first post here, been reading around finding lots of useful info.

I picked up a 2010 174 SF, 3.0L I/O, on Friday and have been trying to educate myself before the first family outing later today. It's my first bow rider, first I/O, been using a tinnie with a 30HP outboard for years now.

This may be a dumb question but what the heck is the exhaust manifold drain for? The boat came with all the manuals but I can't find mention of that anywhere.

Thanks!

Draining it for winterization so nothing cracks when frozen is my guess

Yup, you are right. Finally found it on page 68 they just didn't call it by that name so searching was falling.

Thanks for the reply
