This same write up idea would be good for all the boating Magazines that are still left out there as well.

Your new pump housing goes past just the High performance crowd, You will have the sea rays, Bayliners, cobalt style boats wanting in on the action as well. I hope it goes well for you, Good luck with it.

This would be an awesome episode of ship shape TV. Instead of the latest and greatest mold cleaner how about the latest and greatest water pump that will stop mercury from mugging us every time we need to service a water pump

I couldn't agree more possibly in the off season we can tackle this project. Thanks for the input.

Best Regards

Also it appears your new pump will fit in place of the newer brass style housing all this while using the old style Rubber impeller, Mercruiser part number 47-59362T1.
Also just so that it's clear, the rubber impeller that fits inside the newer brass style Mercruiser housing, Mercruiser part number 47-862232A2 will not fit inside your new pump housing. Correct?

I just wanted to say, If so Good Job, even if it will not fit all three, still you guys did a good job with the new housing. congratulations :coolcowboy:



As I'm sure all those other repair kits with the stainless steel ware plates are going to work good. I'm going to venture to say i wonder how long they are going to last. I say that because if everyone would think back to the two piece impeller body housing Mercruiser first started using, (See service bulletin Above) We have already went through the real world experience with using stainless steel ware plates.The plates didn't last all that long themselves.

Just about everytime a new impeller was needed it was time to change the stainless steel ware plates due to deep grooves/gouges from either sand or the impeller itself. obviously Mercruise knew of it back then, They sold an impeller kit that came with the stainless steel ware plates that needed to be changed out as well about every 100 hours or so of use.

I am a little curious though, would you be able to elaborate yet on how much testing you have done and how your new pump appears to be holding up thus far? If not, I'll understand.:) Thanks.

I'm going to do my best to answer all of the questions here. First yes we build a one piece housing to fit on all of mercury's Gen4,5, and 6 applications. Then we build a new GEN 7 pump body assembly that we have designed to use the original better quality impeller that's still used in all of their HP engines. We opted for the larger shaft size. Also for those that have had their factory 496 style pumps literally come apart and push right out the front of the housing with the bearing, pulley and all still attached, well our pumps use a safety clip to eliminate that danger.

As for the repair kit your correct that's the whole idea is for the wear plate to wear out with the impeller and not the housing. That way you can service our new pumps down the road for only $69 for new plates, impeller, and gaskets as apposed to a $350-$500 pump assembly.

As for duration of time in the field the GEN 7 pump has only been in the field for less than a year as it is a new product for us. Keep in mind we have been building pumps for over 30 years this is not a new project to us. When Mercury made the new pump we didn't expect it to be so poorly reliable. But now we have witnessed a concerted effort by Mercury to build products that will need replaced. Their not interested in products that last a life time. We knew we could build a superior part.

Thanks for the many accolades we are in development of so many new products the future is VERY exciting....Best Regards

I am tired of the fluctuating cooling temps and leaks from the 496 factory pumps. Got a special deal for someone needing three pumps? I am ready to purchase!

+1, i replaced mine with the hardin marine stainless pump and they are nice! i was not even going to mess with the original, haven't tested it on the water yet but it does not leak like the old one and it has excellent flow from the muffs, i'm pretty sure my temp spikes coming off plane are also gone, though i'm only speculating

Kr1276 , We and many of our 496 customers have now used the Hardin stainless replacement pump with great results and sucess. Its a wonderful replacment part, far better than the original merc pump.
By the way, they do have a great deal on three pumps, they have them in stock and thats the great deal cause if you wait they will be out of stock and on back order as more 496 owners start using them! Be smart order now!

Best Regards,
Ray @ Raylar

Assembled my new Hardin pump yesterday. It looks like top quality unit and assembly was straightforward. Will try it in the water this weekend.

The only difficulty for me was the pulley. The original pulley center lip snapped off last week when trying to use a puller to remove it. Had to order a new one. $75 and 3 days. It took a lot of work and cuss words to install the new one even with an installation tool. I wsh there was a better system for that part.

A Powerbuilt powr steering/Alt puller kit works easily to pull and install. Kit 20 part #648605. I bought the Hardin pump to carry on the boat and had a extra pulley so I can change it on water if needed. Nothing worse then havoing to get towed in because of a raw water pump failure. Haven't needed it yet and it is a great alternative to having to by the Merc Housing every time at their inflated price.
(if changing out on the water just be sure to have a D sized battery or something capable of pluging the inlet hose)

Hardin pump worked great. 2.7 PSI at idle (up from 2.1) right from the start. No leaks and it looks good as well. Nice product.
