Engine adjustments for 2024 Puma STS with lithium batteries?

[Corky]

I have a soon (hopefully) to be delivered 2024 Puma STS with a Mercury 300 Pro XS and a Bob’s hydraulic 8 inch jackplate.  I am using one Proguide 36 volt  50 amp lithium trolling motor battery, a Proguide 100 amp starting battery for my electronics, and the standard Proguide AGM battery as a starting battery.  I may just use the lithium starting battery for cranking and electronics after the AGM battery dies.  The boat is also equipped with an 8 inch Bob’s hydraulic jackplate.  I keep reading that to get maximum performance I will need to lower my engine if using lithium batteries.  Will the Bob’s hydraulic jackplate lower the motor sufficiently for maximum performance, or should I request that BassCat install the Mercury lower to compensate for the lithium batteries?  The prop will be a 24 Fury three blade prop.  Thank you for any assistance you may provide.

Corky,

For the average angler, that randomly uses their boats, we do not suggest lithiums. They can be fickle, require battery leads to be disconnected, or batteries jumped, after long term parasitic voltage draws them down. The upper tier chargers are very technical for some non-techno people. Those alone can causes frustrations and technical misunderstandings.  The single 36 volt does make that easier.

As for the Bob’s plate, it will let you go deep enough for performance, as both the transom height and mounting have been adjusted on the STS series.

Thank you Bass Cat.  You guys are great.  I am more than ready for you guys to deliver my boat.  I simply can not wait.  Well, I guess I can wait because I have to, but I am excited to get her.
