Did not want to deal with the crowd so waited till 5pm to go out for a few hours on my ski.
Cleared the inlet and sucked up seaweed into the jet. Had to limp back to beach and clear it.
Ran east and used my phone go kind of figure out where I was. Dropped vertical jig and got a small BFT on first drop.
The current was ripping and the 2nd drop, the jig did not come up correctly. 3rd drop got some kind of jack. I tried to go back to my original spot but the phone app was acting up, showing that I was not moving. By this point I was discombobulated so just went south east into deeper water. First drop in new spot and another BFT but way bigger. By the time I got it into the ski I already moved a lot and it seemed like I was in 60ft of water based on my jig hitting the bottom very fast. Took me 2 drops to figure that out and then I hooked up to the bottom and lost my jig.
Wish the ski had a depth sounder :USA
As for those bobber type depth finder things, I had one back about 15 years ago. It worked OK if you kept it in flat water. When the waves knocked it around, it just didn't know where it was anymore.

I recommend the next thing you do after reading this post is purchase the Navionics app for your phone.
I must say thought to clean the ski it took me 10 -15 mins. To clean the boat it takes hours. So I will probably be taking out the ski more often.
A 7 amp-hour gel cell battery was enough to power a 3" unit for an average day of fishing on my kayak. I tried a smaller battery before that & was limited to only a few hours of use. I don't remember the size of the smaller battery that I tried first.
I don't know how much DC power the average jet ski puts out or how big of a battery they normally carry. I'd actually be interested to know that if you happen to have that info handy. I would be surprised if they didn't have an extra 2 amps available for accessories, but that is just an unfounded expectation on my part.
I was looking at the 4" garmin echo map, that states 5 watts. not sure how to compute that though.
Watts = volts x amps
watts/volts = amps
5 watts / 12 volts = 0.42 amps
Expect a 0.42 amp draw if the 5 watt number is accurate. A 0.42 amp draw should be no problem.
The battery you listed is an AGM type. Those have a very high acceptance rate & are known to beat the snot out of charging systems that were designed for normal flooded type lead/acid batteries. If the AGM was standard from the factory, then your ski probably has a pretty beefy charging system.
Those are on sale today & tomorrow at West for like 1/3 off regular price.
