Hobie Revo Rigging

Sounds like a good shake down run.

I like the twist and stow but i don't any different, it's all i've ever had. I forgot to unbungee the rudder just the other day and i'm sure i'll do it again...

Your transducer wand can be shortened a bunch, i have a TDA(transducer deployment arm) as well on my portable setup and the trans. just needs to be barely below the bottom of the yak, if that. my transducer is about 5-6 inches under water.

A cup of water seems normal, especially when opening the hatches. The crotch hatch lets alot of water drip in. Try going out for a good pedal without opening any hatches just to make sure it's not a hull leak. The hose douche test is ok but a drive well leak may not be apparent unless under the stress off pedaling(been there,twice ).

Good tip on the mirage drive well leak test.  I was taking a lot of water on board and I was completely wet and dripping.  I know a bit of water got in the crotch hatch.  I can check over the weekend on the hopefully calm waters of a Potholes Reservoir.

The transducer wand is long by design.  I wanted to be able to secure it in the up position using the paddle bungee loop.  This morning I cut the foam for the internal transducer mount and later today I will glue it down just forward of the crotch hatch, between the hatch and the drive well.  The shakedown cruise was too vigorous to give a good measure of the transducer performance on the wand.  Over the weekend I'll run one day on the wand, and the next internally. 

Ok, gotcha on the length.

I need to do a detailed write-up on Ralphs custom swiveling pvc joint someday.

Maybe Ralph will do it, fire up his windows '95 and type her up.....

On Potholes Reservoir yesterday I ran the two configurations of the transducer, on the long wand, and inside the hull.  Both performed well.  The wand did oscillate at moderate speed.  There appeared to be no discernible difference in performance except the water temperature read considerably higher inside the hull.

The transducer is staying inside. 

Spot, thanks for the foam!  It worked great.

I'll save you some frustration, mount the transducer in front of the Mirage drive, they create surface clutter when under way if you install the transducer behind them.

Do you have a drive well seal? It is a little piece of plastic that zip-ties to the back of the Mirage drive to keep water from splashing in the drive well when under power. Hobie catalog part # 81037001. It works.

These do work good, well worth the small price..

How'd you do?

I did notice a lot of surface clutter and the transducer is mounted just behind the drive.  The top 5-7 feet was completely obscured.  Is the clutter due to the flippers passing through the transducer cone?  If so, then when not peddling and with the flippers up the surface clutter should clear.   I can't say I noticed it clearing.  I'll check it out next time out.  Internal mounting is easy, so no frustration here.  I'm thinking just forward of the stern hatch rather than use more space in the front hatch.  Front hatch is good for cart wheels and dry bags, and I'd hate to be stuffing stuff on top of the transducer.

Has anyone used unscented petroleum jelly in the foam puck holder rather than water?  Seems a nice way to avoid having to fill the reservoir each trip and yet avoid gluing the transducer.

A anybody else experience noise on their FF/Gps when shoot thru hull mounting the transducer with foam puck behind the Mirage Drive in front of the crotch 8" hatch? Is mounting in front preferred?
 

If thermoclines can create clutter, then I'm betting the fins from the pedal drive will definitely create clutter and odd readings.  It sounds like troutnut has some hands on experience with the issue.

I'll know after the SJ trip w/Nanook, as that is where my transponder is mounted on the Revo.    holt

I posted the "petroleum jelly" question on the AquaHunters forum and got a link to a good site.  Yes, Humminbird sells a mounting system with includes marine grease, so petroleum jelly should work fine.  I'll bet marine grease works better as it is not as susceptible to viscosity changes with temperatures in the yak.

Also, the guy is using another Hobie hatch gear bucket in the stern hatch to hold his battery.

I am definitely going to use grease, and I may decide to move my battery into a hatch gear bucket.  I'll let y'all know if the grease melts the closed foam.

That's a great idea using a gear bucket in the back hatch for a battery holder. If and when i move my 'ducer inside looks like the way i'll go with the battery box.

If you coat the inside of the foam with silicone, wouldn't that prevent any melting reaction between the grease and foam?

grease seems like it could become a messy nightmare over time or on a really hot day.
