Replacing old 4" electronics

[CBSanford]

I have a new-to-me O'Day 272, which I will sail in the California Delta and offshore along he coast.

I need to replace both my log meter and my depth sounder. Both use 4" cut-outs. I acknowledge that I can trim over or plug the holes in he bulkhead to use smaller units, but I would like to use units that replace in size as much as possible. The existing units are Standard Horizon/Standard Communications units. They are fully exposed to the elements. Obviously, I would like to avoid installing a new water speed sensor (transducer?). The only thing wrong with the existing units (probably) is that the receivers are fully sun-burned and the existing LCD screens are consequently inoperative... Both units use the same LCD screen...

1) Lets budget at around $300. What is possible?
2) I found some manufacturers with split-screen receivers with transducers and transponders for less than $300 (now, I can not find them). Got any advice, names, etc?
3) Any way to repair the existing receivers? (Models DS-1 and SL-1)
4) Because I will need to get a GPS, what are the best bets for multi-function units? I probably can do without a water speed indicator; so, a GPS can function to replace that (sort of). Also, I will not have to cut a new hole in the bottom of my boat or modify the existing... Should I get a bulkhead-mount GPS and a separate, bulkhead-mount depth sounder?

Not sure $300 is possible. If it were me, I would find the same raymarin tri pack if in the budget as I had. Now would be st70's? has a depth, speed and wind setup. IIRC about $1500. There might be some 40 or 50 series from Raymarine that are a bit less, that can talk to the GPS/chartplotter etc from raymarine. Not sure you can get Gaarmin to talk to raymarine or vise versa.

Best to web browse WM, Fisheries Supply here in Seattle, Defender, mauri Pro, Pyacht etc to see what you can find, not to mention the sailnet store.....

I assume your cut outs are round. This can be a problem as many new instruments are square, but some have round bodies, like furuno. I have the same issue and the only true round ones I can find are from Moore electronics and signet marine.

Moor would be the lowest cost and they are round 4 inch displays. Speed and Depth systems are under $500 for both from Defender.com.

Thanks!

When I replaced the original Kenyon Instruments on my previous cs I had planned on using Moor instruments from Defender. They would have fit perfectly. I changed my mind and went wireless w/ tacktrick just because I didn't want to go thru the process of pulling all new wires. I had to glass in the old openings.
