One picture is worth a thousand words.

Nah mine doesn't look like that mine looks like something someone would freak out and say u can't run this its missing bolts. You wouldn't know it was ok until u looked inside the suction housing.  Pics later uploaded

It's a Berkeley pump. And that's what I was wondering my self. But at the same time I see people set their pumps back and the hand hole ends up in the transom so how does that work or is it like a race thing only ?

Apparently you never wanted to ski so bad that you let your wife drive the boat.   

Ah crap, did I say that out loud?

I didn't hear nuttin'.

Put her behind the wheel of a big block powered I/O and she becomes a monster. She won't drive a jet. Probably a good thing.

Hey Mr.jimpen, no difference at all? Well the impeller does produce some "turbulence " itself.lol.Manalive you start see'n what causes turbulence within a jet system that we deal with and it's a miracle they "suck" as good as they do.😂😂.....damn I slay myself😖🔫

. None sir

So I have another question then being a newbie here. If that's done would it be reasonable to think the veins have been ported? Everything inside the pump is painted a puke green

I believe it makes zero difference.  All of the quickest and fastest jet boats in the world use a pop off valve.  The pistons that fill the hand hole opening don't fit super nice, not to mention that most are hideously notched for inducer clearance where the inducer has been moved forward.

That being said, I had a hole in my life that I had to fill with this $10,000 billet hand hole cover.

Blending the hand hole cover void with Bondo or Sea Goin' Poxy Putty will eventually crack and fall out.  That chunk then goes through the pump.  Sometimes you get lucky and it doesn't cause any damage.

People tend to do what is easiest and hope for some gains.  The only way you can know if the bowl is detailed AND if it is done correctly is to look inside.  Even if done correctly, that doesn't mean that it didn't suck up some rocks at some point.

If you want to do that, I would build up weld on the hand hole cover, machine it to a 4.250" diameter, and blend the weld to the inside surface of the suction housing.

Roy Miersch, PPP, makes a nice fitting hand hole cover for Berkeley and Dominator pumps.

I don't recommend welding the suction housing, the heat will warp the thrust bearing and wear ring size and alignment.

Have fun,

Joe
