The Buckshot Racing #77 Delco-Style Marine-Grade Solenoids with Silver Contacts are rated for a continuous 300 amps (vs intermittent 105 amps).
Silver is the most conductive element for electricity. It has a high number of free electrons, a unique crystal structure, and a single valence electron.
 
These can be used as replacements for new or existing trim, tilt, and start applications in your high-performance race or river boat. 
 
Our Silver Contact 300 amp Solenoids have several advantages; including stronger conductivity, better sensitivity, and a higher melting point (less chance of welding, and/or material transfer) running 12v, 24, 36v systems in high-stressed, fast-trim, and dock-start race applications.
