Otherwise making my own is fine but I kinda just want to bolt it up and run, to many other projects going on!

IMO, bolt on means engineer to fit..... :-D

There is a pump with the support bolted on the opposite end.

So when u go to the crank style pump do u have to get custom hoses and plumbing to get the raw water where it has to go or will regular hoses work in most cases? It seems to me that even though changing impellers becomes easier to do because of access, the time and extra cost to re-plumb is it really worth it. Present impeller change only takes about an hour per pump now?

Yes I will have to get new hoses they just need to be a bit longer (I figured 10ft @$60)I found the f6 pump online for $120 each vs $130 for a major rebuild for the Sherwood. To me the entirely new pump is the way to go. I am also not for sure on the condition of my Sherwood pump housing on the port side being the bearing has play and the shaft looks a little rough as well.

Just ordered the pumps today decided to order from Marine parts source a little priceier but there shipping is free and the stuff always arrives the next day. $159 for each pump and $36 for 6 feet of hose. Decided to figure out my own mount as we just got 18” of snow I have some time to fab something up!

Can’t wait for the peace of mind having new pumps!

Good stuff.....honestly I think the only challenge with the install will be to get the pumps to rotate on center correctly....the closer the better.....looking forward to hear how your install goes....... :beergood:

Got the pumps today...should I take the impellers out and spin them in the correct orientation for my reverse rotation motor? I’m assuming they will be fine once I fire up motor and correct itself. Thanks for your input.

If it were mine I would take them both out ,inspect them , soap em up and put in the correct orientation.......never can tell how long they were on the shelf waiting to be sold......

In general they will flip to the correct direction themselves when you fire up the engine but you can do that by hand before installing it. It's always best to eliminate that stress on the few blades that are already curled the wrong way on the cam but if they are properly lubricated, this isn't that big a deal, I just wouldn't rely on them already being lubricated properly enough to eliminate the stress of flipping them in place. The most important thing is what bud mentioned; you don't know how long those few blades resting on the cam have been in the bent position. It's unlikely that they've been cycled periodically since they left the factory so it's best to be sure but you might be able to see through the ports if they've taken a set as you turn the pump by hand. If you take it apart and pull the impeller, just make sure you don't open up a can of worms by wrecking a gasket or nicking the two mating surfaces while trying to get the impeller out. Better yet, remove the cover, and turn the pump without removing the impeller and check that the blades on the cam straighten out when you turn the pump. Then just put the cove back on. Hopefully the gasket will remain intact.

BTW, the blades resting on the cam for extended periods is one of the reasons why I give my engines and genny a quick crank a few times over the winter. I don't like the impellers and other major engine components like springs, etc. resting in the same position for that long. Maybe overkill but it makes ME feel better.

To add, sometimes with brand new, you may find sharp edges overhanging ports that need to be dealt with etc....just optimizing flow really....nothing overkill about rolling machinery over, good practice IMO........ :beergood:
