Default Hooking up Garmin 4212

I got a Garmin 4212 for Christmas and have a few questions.

It will be installed on a 1989 35' Egg Harbor with 454 mercs.

I don't have a hard top and wonder what the best place for the GPS antenna will be. Will a canvas soft top over it be fine?

What transducer do you recommend? I'm on the Mississippi River so fishing isn't important and I'd like to have a shoot through for ease of installation. I was thinking Airmar P79.

Will this unit hook up to my engines and fuel gauges? I assume I'll have to get the fuel flow gauges for this to work. I'm not sure about the engine monitoring.

Thanks in advance.

GPS Antenna will work fine with a soft top over it. It'll even work fine with a hard top over it.

The P79 is an easy 30 minute install and if you don't like it you're only out $80 and you can always leave it installed as a backup. I have one and am happy with it.

Engine and fuel, you'd need to have NMEA compliant data sent from the engines... that'd probably set you back some $$ and you'd have to think about whether or not it is worth it. I can tie in with my outboard data and the gauge display etc is interesting but not really practical. Fuel flow on the other hand is nice to have so that you can get a quick view of your economy.

Install 2 lowrance EP60r fuel transduces inline on your fuel lines and you will be able to display fuel used/rate/mpg.
Garmin also makes one but at twice the price. Being N2k either one will work

I wouldn't put a p79 on an Egg of that vintage for fear that many places you have access to will be pushing the 1 inch thickness max of the p79. Go with one of the low profile thruhull transducers, either the B114 if you have less than 10 degree deadrise, or the b60-12 for 8-15 degrees of deadrise. I don't see you having more than 15 degrees of deadrise, but if you did you could go with the b60-20. Your GPS will be fine under a soft top.

Thanks for the responses. Can't wait to try and snake the wires from engine room to the bridge.

I have time to think about it. -22 on my way to work today.

Its that cold and your boat's still in the water? If its out, a thru hull is a no-brainer.
