This switch is for a 1997 Chris Craft Ultra Concept 21. It is an exact replacement. Installation was simple.

Can you buy lanyard only?
Yes it is this: http://www.iboats.com/Coiled-Lanyard-Cut-Off-Switch-Replacement-for-Sea-Dog-420489-1-420488-1-Cole-Hersee-M-598-Sierra/dm/view_id.187621
I have a 85 25hp mariner, will this fit and replace the push button cutoff?
This is a universal switch. It will provide a normally open or normally closed circuit. It just depends on your application.
