Teather, how is it wired to twins per regulations

I could'nt find any fed regulations per say, but maybe you can find it, I just did'nt have the time to look at a million pages of text right now..

You can start here, and explore further, too much info, but I'm sure it's there somewhere..

Seems the biggest safety requirement/concern is grounding,Bonding, (just like the NEC rules for home/commercial wiring)

So I'd just wire it to the ignition circuit (coils) and since you have 2 engines, make sure the ground is wired directly to the negative bat terminal and if you have 2 bats, bond the negs together... I would think that would satisfy any regulation if there is one..

Twins = 2 swiches.

Are they in series with two switches? If not, then what if one engine kills but not the other

I believe that mine is set up one per. I connect them in the same place so if one goes so does the other.

I was thinking, what if one lanyard broke and it didn't shut down the switch? If one engine was still on and one dead the situation could get worse.
Can one switch be used for both engines?

ditto

It's a good question....

Per Rules & Regulations, I don't know..

As to if it's possible, You bet it can..

I can't think of one reason in this world why you couldn't, or why anyone wouldn't..

Yeah, I see newer boats that have twins have two teathers. I man, two teathers tied together makes no sense to me. My Bertram only came with 1, so for now I will install the two engines in parallel with one switch. Thus both engines grounded out at the coil when teather is pulled. At least I Understand how it works.
Solo out. irate:

This subject made me think about a twin engine boat. I have only owned single engine boats but I am certain that a twin is in my future.

I looked at Formula's web site and the 382 with twins has two switches in the pictures.

My thought is if I have a twin setup with two switches my preference would be for either switch to shut down both engines.

Aquaforce, you are correct I belive. it makes the most sense, and safety.
Thanks
