We are a boating family. I get a call last night from my dad. Tells me 'all the guys on the dock are having problems' It seems that many of the boats, new and old are having there engines lose power or just quit. The reason is that the gas filters and In-Engine screens are loading up with Varnish from the gas tanks. This new gas mixture is causing the varnish in the gas system to gel and flow into the filters and screens and gumming them up. It seems the Injected Yammy's are very suseptable to this. The in engine screen is like a two hour nightmare to disassemble and clean. Warranty doesn't cover it.<br />So just be aware if you have this symptom. Dad says that 30% of the folks at the dock have issues. That's a big number.
