Just an FYI. I burnt my glow plugs and had to replace all three - the toggle switch I have for the glow plug circuit was left on last time, and the plugs burnt out. Couldn't start the Universal M25 motor without them (in a Catalina 36).Pulled them, and they are marked NGK Y103K. The boat yard had them in stock - Universal P/N 299685. Plugs were in Universal parts bags (sealed). Plugs are marked NGK Y103K. $30.00 each.Checked Marine Diesel Direct today. Price: $63.69 each.Checked sparkplugs.com today: Price: $8.60 each.http://www.marinedieseldirect.com/universal/shopping/allresults.php?mfc=Universal&kw=299685&searchtype=partnumber&functiontype=allresults.phphttp://www.sparkplugs.com/results_cross.asp?pid=y103k&x=0&y=0I'm going to do two things:1. Replace the toggle with a momentary contact switch.2. Order a spare set of glow plugs. Guess where I am ordering them from.jv
