No VSS=Idle trouble, mostly. Wouldn't think VSS would limit RPM, but I
would try switching the neutral/park pin briefly to see if that had an
effect. If you set it to "Drive" and there's no VSS it'll set a code
eventually, but it'd be a worthwhile test on the 4200 RPM question.

Disabling IAC completely isn't such a bad option probably, for a
boat...tho a RNDL switch helping to control idle would make a nice touch.
