I wouldn’t use anything less than the rule 3700 on our boats. Right I only have 4 of them but will be adding a 5th one. That will bring total capacity to 18850 GPH... yes I know the 3700 rating is zero head full voltage but even 3000 each will be pretty efficient. Plus every second count and the electric pumps will kick in right away.
Crash pump are great but storage is an issue and then deploying them takes time.
The boat i run has a number of 3700 plus a 240v electric pump with manifolds to three areas. That’s great as long as one of the gensets is still on line, you have time to go down to the ER and prime the thing...
