The Great Escape II

Mike As long as it's listed as UL2034 it is ok for Marine use. This is what I replaced mine with and it is UL listed as stated. https://www.homedepot.com/p/Kidde-Worry-Free-10-Year-Lithium-Battery-Carbon-Monoxide-Detector-with-Digital-Display-2-pack-21027473/207088780

Give them a call they are very helpful

Here's my post on this very topic. http://forum.chaparralboats.com/index.php?/topic/39759-yacht-device-install-on-a-2005-volvo-gxi-e/&tab=comments#comment-431771

Go get a membership to Planet Fitness for $10 a month and call it a day. Let them deal with the crap that breaks.

Which prop is stuck?

Todd, Just to let you know if you DO decide to replace that top cap you have to re-shim the gear housing. It is in the service manual if it has to be replaced and I'm letting you know from experience. Google it to see how.

Not necessarily on screwed in snaps, it's called crevice corrosion and happens a lot in the marine industry with stainless steel. https://en.wikipedia.org/wiki/Crevice_corrosion

Are they screw in snaps?

See attached install manual for the Totalscan Transducer I mentioned. This is on page 7 on mounting it direct step or jack plate mounting. It will not track bottom when it's out of the water like you mentioned but they do list it as a installation option like I stated. ftp://software.lowrance.com/Documents/TotalScan-Transducer_IM_EN_988-11051-003_w.pdf

Dimmer for the dash/helm lighting.

It also depends on what type of transducer. Some are skimming, some are in water and some are above water. What transducer do you have? We run Simrad with the Total Scan Transducer and our set up is skimming. Ours is adjusted so when you are on plane the transducer is SLIGHTLY below the water.

Our Signature does not have it

Also make sure you use a pressure regulator or you will blow your hoses. Most add on marine water connections have a built in regulator. Also make sure you turn it off from the spigot when not at the boat. We have salvaged many do to a fixture or plumbing failure when the water was left on. https://www.westmarine.com/buy/shurflo--flush-mount-water-regulator-inlet--183725

If you run Volvo they HIGHLY recommend a starting battery for their motors. Use a starting for the motor and deep cycle for the accessories.
