SEAFLO thru hull fitting for marine bilge port outlet vs Tsunami Mk2 500 Aerator (Attwood) 12V 1200 GPH

Overall winner: SEAFLO thru hull fitting for marine bilge port outlet

Key Differences

SEAFLO (A) is a thru-hull fitting noted for strong build quality, corrosion resistance and a lower listed price tier, making it a straightforward choice for plumbing and hull penetration needs. Attwood Tsunami Mk2 (B) is a compact 12V aerator pump geared to aeration tasks and offers easy installation for livewell use, but reports of mixed flow performance mean it’s better for buyers specifically needing an aerator rather than a general thru-hull fitting
