It was a drama filled weekend with people telling me do this do that, get this get that, fix this fix that blah blah...anyways. One thing that really concerns me b/c of how big a deal he was making it was a friend of mine (thinks he knows everything about everything with boats) was telling me was that my transducer for my GPS/depth finder shouldn't be where it is- on the back of the boat and in the water- but it should be inside the hull. The reason this came up was that sometimes when we were running the depth display would blink indicating it wasn't getting an accurate reading rather than staying still and adjusting every few seconds. Experienced boaters, what do you guys have to say about this?

It is working fine and can be mounted either way. You are losing bottom when running because the boat is traveling faster than the transducer can receive thensignal. Once you stop it should go back to working.

Congrats on getting a PRE-OWNED boat...the only way to go.

Hull or transom. Transom is easiest and most common. Usually works just fine. However, some hull designs simply give problems (unique curvature lines), but some sort of tweaking will usually fix it. However, occasionally it won't. I had one of those problem children about 20 years ago. Finally just had to mount inside the hull...problem solved

Military small boats have hull mounted transducers.

I would try tweaking it like the previous OBers suggested. Only if that fails would I hull mount it.

Sounds like the transducer is experiencing cavitation from the prop wash (being mounted to close to engine) or is at the wrong depth/angle for the hull. It should be mounted parallel to the hull running surface and at least 15" outboard of the engine cavitation plate.
