TYPICAL APPLICATIONS Marine Review: Original RULE switch (fairly new) would occasionally not "start" unless given some wave action, and needed a larger swing area under engine block. Heavy rain and calm marina was a recipe for disaster. After checking on boat and finding it didn't engage (starter almost under water on new 5L merc.) I installed this this one. 3 days of rain and every day I check it, it has done it's job more efficiently than RULE brand. Cheeper than a $25K engine replacement. Review: Works like a champ. Prior to this one, I've had two other different brands of bilge switches quickly fail after only a month. This one has been going for over four months with no issues. That is very appreciated given I have a deep bilge and it is a PITA to pull the pump/switch assembly out for repair/replacement. ## Features - 4 Year Warranty - Turns pump on when water level reaches 1.77" (45mm) and turns pump off when water level reaches 0.79" (20mm) - Constructed with high quality ABS material and newly designed sealing for maximum durability and longevity - Mercury free electric reed switch system for consistent activation performance. - Brand new design can handle 12V, 24V, and 32V systems up to and industry leading 30 Amps ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07VG9K2V4 | | ASIN | B07VG9K2V4 | | Best Sellers Rank | #104,801 in Sporting Goods ( See Top 100 in Sporting Goods ) #168 in Boat Plumbing | | Brand Name | SEAFLO | | Color | White and Orange | | Customer Reviews | 4.3 4.3 out of 5 stars (169) | | Customer reviews | 4.3 4.3 out of 5 stars (169) | | Date First Available | 25 February 2015 | | Global Trade Identification Number | 00700621157878 | | Is Discontinued By Manufacturer | No | | Item Dimensions L x W x H | 7.6L x 3.3W x 13.2H centimeters | | Item Weight | 0.44 Pounds | | Item model number | SFBS-25-03A | | Manufacturer | SEAFLO | | Manufacturer | SEAFLO | | Material Type | Plastic | | Model Number | SFBS-25-03A | | Power Source | Battery Powered | | Product Dimensions | 13.21 x 7.59 x 3.28 cm; 199.58 g | | Product Style | Bilge | | UPC | 700621157878 793945653676 647336950045 796793285747 | | Unit Count | 1.0 Count | | Voltage | 12 Volts | ## Product Details - **Brand:** SEAFLO - **Colour:** White and Orange - **Material:** Plastic - **Product dimensions:** 7.6L x 3.3W x 13.2H centimeters - **Style:** Bilge ## Images ![SEAFLO 03-Series Heavy Duty Bilge Pump Float Switch for 12V, 24V, 32V - Image 1](https://m.media-amazon.com/images/I/5142M0+9E7L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐ Review *by K***C on 27 October 2022* Original RULE switch (fairly new) would occasionally not "start" unless given some wave action, and needed a larger swing area under engine block.

Prior to this one, I've had two other different brands of bilge switches quickly fail after only a month. This one has been going for over four months with no issues. That is very appreciated given I have a deep bilge and it is a PITA to pull the pump/switch assembly out for repair/replacement. ### ⭐⭐⭐⭐⭐ Review *by E***S on 5 April 2021* Incredable float switch right here. I used this float submerged in 175 degree water for over 3 weeks. It worked perfectly the entire time. Did not expect it to last due to the water temp. I was wrong. Pretty impressive float switch.
