The iboats forum moderators are excited to announce that at this time it appears the iboats forums posting pictures function is working once again. Though we cannot promise for how long, we're hoping for indefinitely.
Could use a serial number to make sure, but the Magnum doesn't have trim senders. The later version called the HP assembly used a single 3 wire trim and switch. It was used with digital gauges.
Mine is the HP and I have the single sender and also installed the Digital to Analog Merc converter, but it still doesn't work.
well poking around seems there are knurled press inserts- unfortunately just not for the 5/8 in marine stainless.. that would have been a real easy conversion! Hole is a few fractions less than 7/8..
