Looks like I've finally lost my port tach, I've been messing with the 4 - 6 - 8 position switch on the back for a while but now it's just dead and the starboard one is jumping around at idle. All my other gauges work fine, so I think I'll just replace the tach's. Has anyone found a good replacement for the original Det-Mar's ? Rick Ticket 85 SF Merc 454 MPI's Falmouth, MA

I put in Faria tach's when we got our boat 11 years ago as they matched the other gauges. Occasionally the 4/6/8 switch needs to be cycled on one of them to fix erratic readings. It's not the first brand I've had that problem with.

Thanks Bill.....thought those looked pretty close Rick Ticket 85 SF Merc 454 MPI's Falmouth, MA

Rick, I just did a complete overhaul of all of my gauges and hour meters about a month or so ago. I went with the Faria Chesapeake-Black gauges and they look great day/night. Previously, I used the same gauges, only in White for my old 28 and they just didnt look as good in the 33 dash. So far, so good! All the best, Jim

I used the Aetna engineering digital tachs. Great product and service. Digital was great to easily sync to within a few rpm.

Thanks guys - I'll look at them both ! Good to see I'm not the only one that needs to do them ! Rick Ticket 85 SF Merc 454 MPI's Falmouth, MA

Rick, Hang on for a little while. I think I may still have the Detmars when I replaced everything up top. I just have to search for them. If I have them, you're welcome to them. Al

Thanks Al, I have plenty of time. Pulled from the water on Wednesday, not going anywhere for a while ! Rick Ticket 85 SF Merc 454 MPI's Falmouth, MA

I hear u Rick, Ticket is prominently displayed by the road for everyone to see. Bertram Proud! I came out Friday afternoon. Must be much better to not have to take the trip back to Danversport& have it close at hand to work on. I put in flowscan twin tachs in one gauge & twin flowscans in the other. But I think flowscan has gone out ir is going out of business.
