Yup, 7 & 8, I think you'll find Drew is right on. Doug

No, it hurts because I have so much to do!!

I would like to knows where all these excess hours are... I seem to have lost them.

Probably your fastest, easiest way to get back on the water right now is to put the new Dart heads on. They are about half the cost of merc heads. Then later in winter they can be ported and do the rest of the package. If your heads are really bad (flange corrosion, guides badly worn etc.) It's more cost effective to use the new dart head. Before they came out w that head you had no choice but to fix them because the merc head is very expensive.

I'm not sure if it applies to your 525s, but there is a Merc service bulletin, deals with removing the lower bypass hose. Doug
