New v20 owner

[Ambush]

Hello all,

I just bought a 1985 v20 with a i/o 3.7 Merc cruiser.

Nice boat and reading how you guys like these boats I knew I'd be ok with a great board like this..

I also have a 1965 IH Baby Scout and I am on another board just like this.

Q: After a new bat and one cable and a starter selonid it will only start if i jump the one post on the starter. There is a wire (from the selonid) leading to what looks like a preoiler? Is that waht that thing is? Oh its a water cooled voltage regulator?
Thanks in advance...

Don
