"WAYPOINT" 1999 C400-2, 1999 has a Vetus throttle /shifter. We have been having problems with the red button getting stuck in the depressed position. I replaced it and it worked for only a short time. 
I just received a new unit from West Marine that looks like the original. 

Recently there were posts about a Seastar unit. Is this the correct brand?
