The garmin has a relatively small 6" transducer (tm52hw) and the simrad equivalent is over 10". I'm a little worried about that between twin engines. Any comments on the tranducers?

Transom mount are the cheapest and easiest to install but also the most affected by turbulence in the water. If you can swing it, a thru hull would be the way to go in my opinion. On my last boat we had a transom mount on a deep 25 foot center console and it lost bottom at around 25 mph no matter what we did. Went thru hull a couple of years after we got it and never looked back/had a problem. Far more expensive though. With that said, my current boat is only a 20 footer with a single engine and the transom mount works great.

Here's some insights:

Thanks! So, for fishing maybe B175HW for winni? I'm not that familiar with these but it seems with < 200' depth Wide would be almost necessary. If I want to map the bottom for fishing or diving then B285HW? Pricey though. Is that kind of external mount crazy in a sport boat? For the $500 difference I could probably buy sonar maps for winni :-).

With the kind of money you are talking about spending I would definitely huddle with a good marine electronics shop and make sure they understand your planned use and boat set up. You might also want to look at a boating forum like the www.thehulltruth.com for insights into transducers (and equipment for that matter). There is a ton of good information over there and almost certainly people that have the equipment you are thinking about.

We have the Lakevu HD map on our Garmin; the detail and accuracy are excellent. My only gripe, previously mentioned, is that flashing lights are all marked as white rather than the color of the companion marker. All red or black markers without a companion FL are correctly marked red or black.

As I only use the sonar for depth, I have the basic transom mount transducer. That works with the 22' single outboard Eastern.

I was planning on swapping in the new MFD myself and I just want to be sure I can get the right ducer with what I pick. I'll probably put in the simrad with navionics maps and then get Irwin's to install a totalscan transducer if they think it will work or spring for an in-hull if not.

thanks for the help!

Have you looked into in hull vs through hull transducers? I have an older in hull trsnducer in my boat, and it works well with no issues or worries of a through hull.

I'd consider it again if I was looking for a new unit.

I think my searay has the kind of hull that has air gaps in it and in-hull doesn't work. Maybe I should call searay and ask to be sure. Can chirp work in-hull?

Yes, CHIRP units will work with in hull (shoot thru) transducers. I think what may be referring to with your hull is that it is cored (meaning there is some type of composite material sandwiched between two fiberglass layers). If that is the case and you go with an in hull you have to cut out the top level of the fiberglass and the coring material so that the transducer sits on the bottom layer of the fiberglass. Hopefully you don't have any air pockets/gaps.

I'd be surprised if a Sea Ray was like this, but it could be. There may be some areas in the lower part of the hull near the keel to allow for this, where other parts of the hull may be of a cored construction.

But there are some Garmin chirp in-hull, just check to be sure it is compatible with your head unit:

There are others also, I just happened to click on that one first.

Whatever you decide to buy, check out Gander Mountain's website. I got a few bucks off for joining their mailing list, then waiting until they sent me a few more bucks off ($20 off, free shipping seems to be about every other day) and they were offering a $50 Lowrance rebate and I found an additional $50 rebate on Lowrance's site. All of this on top of the clearance price. So I got a last-year's-model Elite 5 for $170. Sold the old non-GPS fishfinder that came on my boat for $120 on ebay and I'm into a new color DSI 5" GPS fishfinder for fifty bucks. This was in January. Deals may have changed but Gander Mountain is going out of business and they seem to want rid of their electronics inventory in a bad way.
