Just brought the boat out of winterization. Don S., can't say thanks enough. I used your directions and the outdrive manual as guide/bible and it was extremely helpful. Had to do it at night, so I'm still working on the pics. The accessories are run by v-belt, which is puzzling. When I got it fired up, i noticed no tach reading. I only had it out twice last year after I bought it and it was working okay then. From the manual it looks like a grey? wire coming off the distributor that goes to the guage? Just looking to get pointed in the right direction. Boat is 2002 Four Winns Horizon with re-powered 5.7L with mixed-breed accessories (should have named it "Franken-Four Winns"). Again, Don S. thanks a bunch for all your help.
