  • Thru Hull Transducers

    Thinking about switching my transom mount transducer to a thru hull. Looking at the Airmar ss164 for furuno 1735. Anyone have any experience with these transducers?

    For a glass or aluminum boat?

        I only run in the rivers but my transducer is inside the hull and shooting through(no hole) the aluminum hull. It works just fine for for the depth finder, [I have not tried it over about 35ft] I don't know about the fish finder side of it. It is a nice feeling to not have to worry about wiping a $80 puck off. It would be real simple to test if it would work in your boat. If interested PM me for more info.
        One place to get some info is http://vexilar.com or do a search for 'sounder epoxy'.

          Use a through-hull with a high speed fairing. You can't use a shoot through with aluminum and if you use the flush mount you will lose about 20% definition. I have the Airmar 526TID-HDD. It is great. The 520T-HPT is OK.

            And just why do you think 'shoot through Aluminum' won't work? It sure as hell works in my boat!!

                dtol,

                Can you see the bottom while you are on step? How fast can you go before you lose bottom definition? In how deep of water?

                  I have been 49mph on the GPS without loosing the bottom.

                    Can I install an in-hull transducer in an aluminum boat?

                    Airmar does not recommend it. The transducer's sensitivity will be reduced transmitting through the metal hull, so you will not be able to see as deeply into the water. However installation in an aluminum hull is acceptable if the thickness is 3.8 mm (0.15",3/16") or less. The transducer must be epoxied directly to the aluminum hull. Use Airmar models P72, P79, or M260.

                    From Airmar. Go for it if you have a thin hulled boat and intend to stay in shallow water. Don't if you want maximum performance from the money you spend.

                      A Glacisercraft boat does not have a flat bottom, if the transducer is not pointing straight down you will not see what is under the boat. You will also need make sure the location is bubble free.

                        The fairing takes care of the angle of the hull.

                            Music Man,
                            Have you ever run it in deep (150+ ft) water? If so how does it do?


                            dtol,
                            Where do you lose bottom at with regards to depth and speed?

                            Thanks for all the input!

                              Ebbtide: I have never been in the salt. It is very accurate shooting through my .250 bottom. I think it would work to ocean depth too. It wouldn't take much to test it out on your boat. It could be a temporary setup with a pice of pvc pipe siliconed to the bottom and filled with water with a weight of some thing to hold the sender down. In fact this is the prefered method to test a location before it is made permanent with epoxy.
