PENTAIR SHURFLO 4238-121-E07 Blaster II Washdown Pump - 12V 3.5 GPM 45 PSI High-Pressure Marine RV Deck Self-Priming Durable Corrosion-Resistant Co-Molded Diaphragm Quiet Thermally Protected Pump

Same exact pumps in my robalo looked different online and was a lot cheaper here but when I got them they are exactly the same ones great oem replacement

Very satisfied

I put a flow meter on it and sure enough 3.3 GPM , not bad considering all the losses in the piping elbows, etc.

My original Shurflo is used for the sink, the shower and as a wash down. It started leaking, so I did looked a replacements. Almost all replacement pumps have poor ratings and are replaced often. I paid the extra money for a new Shurflo, because I do not want to replace it again for many years.The new pump is almost noise free and was easy to install.

Dont let model number suffixes fool you. this is the same pump found in SeaHunt and many other production boats. the oem ones have a wiring plug wired on them instead of bare wires. the models are basically the same pump

Read the reviews on longevity. If you like having to replace a raw water pump, which is located in hard to reach places (bilge), then this definitely the pump you should buy. I’ve put two on in the past two years. Each lasted just over one year. The last one I purchased and installed on 3/18/23. Fished this week, and pump is locked up. I didn’t, but if you insist on buying this pump, I suggest you also buy Amazon’s 3 year extended warranty for $40. Not happy. There are much better and more reliable alternatives, but the Shurflo pump is a direct replacement for the original OEM pump. Oh the joy.

The pic shows a 5.0GPM pump. The verbiage shows 3.5GPM.Not a big deal unless you only look at the pic. I'll admit that I only look at the pic. Started in my youth with a "Mens Magazine" published by some guy named Hugh. They say that the writing was top-notch, but I sure as hell can't vouch for that! The chemicals we men are forced to carry around inside our heads are potent and not to be trifled with. They can affect/effect your personality in all kinds of untoward ways. Those were some good pics!Oh, the pump. Sure looks nice in the box. Have yet to install the mofo.OK...Installed the mofo and it's AOK, super-duper, Top-Notch and all that. Has a PSI switch so that when it's made pressure it shuts the pump off till you open the spigot. NICE. Hope it lasts. They tend to put the WORST corrosion coatings on these things. They last a year or so (in saltwater environment) and they crap out. Sort of like pre-planned obsolescence but more like, "just keep buying them and keep us afloat".Salty water goes in one side and comes out the other. What's not to like?

The Surflo pump works well have have had good luck with them in the past so got it again, an inlet screen/filter will help the pump last and you can get rebuild kits for it.
