bilge pumps for Tiara Express 3500

[neto]

So I bought a boat recently (3500 tiara express) and it need some love.. I found out that all of the bilge pumps need replacements because some either work and throw the breaker every now and then or dont work at all. I live in Puerto Rico so rain and storms are very common here, this boat survived Hurracaine Maria without problems (according to the previous owner).

I am planning on doing 1500 gph bilge for each area (FWD, MID and AFT), is this good enough? or should I get a bigger gph pump or maybe do two on a specific area? What is the most important bilge pump?

I would think three 1500 would be alright. If you wanted some peace of mind, maybe jack the aft one up a bit. Would make sense for that one to be the biggest on boats our style since when underway, water runs aft.
