How much battery are you looking to recharge?
How much time will you have to recharge?
Typically marine chargers cost a premium for the splash proof certification.
I gave up trying to find an Automatic charger which could fit all my battery needs. I went with a 500 watt adjustable voltage switching power supply.
It can provide 600 watts, or 41 amps at any voltage between 19.23v and 13.12v.
But it is a manual charger. I either set it at float voltage for when I have a lot of time to charge, or crank it up to 14.9v to minimize charge times. Leaving it at 14.9v for too long will overcharge the battery.
16v equalization sessions are easily accomplished as well.

I do not trust any automatic charger to do the job which it claims to do. Most flash the full charge indicator very prematurely, and drop to float voltage.
Float will eventually, in many cases, fully charge a battery, but it might take a week or longer.
Recently, I took 65 AH from my flooded battery, set my MeanWell and Solar to 13.6v, and 5 days later the specific gravity was only 1.270. Maximum SG on this battery is 1.285. 2 hours at 15.3v at that point got it to 1.280. Usually 16v is required to get this battery to 1.285 or higher.
Since no automatic charger is actually taking specific gravity readings, they are basically guessing as to when the battery has spent enough time at absorption voltages.
