204c hull bottom contruction

[bottomline]

I have a 1987 204c.

I'm considering installing an "in hull-shoot thru" transducer for my fishfinder.

However these transducers require that the hull material be solid fiberglass and NOT be cored.

Can anyone tell me if this model/year has a cored or solid fiberglass hull ?

Thanks

No coring... straight fiberglass. You'll be fine with a shoot thru.

I know a lot of people don't like transom mount ducers, (cosmetically, drilling holes in transom, vulnerable to bottoming out and growth, etc) and I understand that, but.. as long as the transom mount is positioned correctly, it's the least expensive method with the best results. Good signal return, (no loss of power) and no seperate water temp sensor.

If your not too concerned with "having the best possible signal" the shoot thru is fine. On the plus side, there's much less of a chance of losing signal due to turbulence.

No need to epoxy it either. Clean up the area with acitone, mineral spirits, etc... lightly sand and use either Lifeseal, 3m 5200 or 4200... any decent silicone sealent. It's strong enough to hold for many years and if your not happy with the location, you can still remove it. clean it up and reposition it.

Just drilled a hole in mine for a thru-hull. Fiberglass is 1/2" thick.
