I recently bought a 19' Chapparal with a 5.0L Volvo Penta. I am new to I/O's having owned an outboard for many years. What is a typical temperature reading when running full throttle? Mine seems to run between 180-200 F, which sounds high to me. I may have sucked sand thru the water intake and would like to know if I have some troubleshooting to do. Thanks for the input.
