ACT, ECT, TP and ISC-BPA - automotive or marine?

[Chexi]

Does anyone know which of the following are marine-specific parts versus which can be purchased at a NAPA or similar store?

Air Change Temperature Sensor (ACT)
Engine Coolant Temperature Sensor (ECT)
Throttle Position sensor (TP)
Idle Speed Control (ISC-BPA)

Thanks.

For GT-40. Sorry, forgot to post that info.

I would think the temperature sensors are not marine specific. I believe there is a table for the ohms VS temperature curve on both sensors in the GT-40 service manual. They are just temperature sensitive resistors.

The TPS may be marine specific, as well as the idle air controller. But it would not surprise me if they are not.
