Default Best option for Bravo One Sea Water pump ?

What are the cool kids using for sea water pumps nowadays? I've been looking all over and I see tons of people having problems with what seems like every version of Hardin's pumps. I love the idea of stainless but am I better off just running the stock plastic pump and rebuilding it every season. I'll be in saltwater, probably never rev over 4500 rpm, 383 SB with heat exchangers. I ran across a post regarding crank mounted Johnson pumps, people seemed to like them but I haven't heard enough feedback to go that route. I had one on my old Wellcraft when I was a kid and it leaked like a *****.

Is there an option that has a plastic housing and two wear plates, I have seen one wear plate, seemed to me it should have on on each side....?

i had cam driven water pumps,,switched to normal cir pump, then added a johnson crank driven water pump. i have not had any issues, but only on second season.
the cam driven was nice, as you didnt need a sea pump, but i had replaced on pump and impeller in 4 seasons.
i also questioned the mounting on the johnson pump to lower pulley,,,so i had my machine recess a pocket in lower pulley for pump to give a very secure mounting set up.

i also made bracket to hold pump.

With all pumps there are wear plates. If the pump is reused the wear plates will need to be replaced. If there is enough room to mount on crankshaft I would place there because its so easy to replace/repair. I have a Hardin pump and used it 2 seasons, but going back to plastic

What's everyone's issue with the stainless hardin's? I have one and it pumps water like a mofo! Are there hidden issues that I'm not seeing?

That being said...I love the hardin...fittings are stupid expensive to screw in but besides that I haven't seen any issues with it and it looks sweet lol

For me there are 2 issues.

First, weight I have to hang upside down to install, and the thing is heavy in that position.

Second, there is a machined surface inside which was not done properly and causes added wear on impeller (factory defect). The impeller pumped fine for 2 seasons but the second season I was seeing pressures a bit lower. This will be the second season on the plastic housing and will compare

I gotcha...being a single engine in mine with room the weight thing I don't have to be concerned but def see what you're saying..they aren't light lol. I did notice some pretty sharp edges on the inside but pulled it apart after 8-10 hours run time and didn't see any wear on the rubber from it. I purchased mine fairly recently..I would say within the last year and a half or so...wonder if they fixed the design flaws?

Replace the impeller and plastic housing each season. Its about $40 more than just a good impeller.

I run stock and just replace them when needed. Order the kit with housing. Don’t cheap out. But the good quicksilver stuff and you’ll have no problems.
