Same one you can buy Bob, The blue printing is on the INSIDE of the pump! LOL.... I have not used the ''NEW"" ones as of yet. But Lots of us on here Do, I have not heard of any problems. for 150.00 they are worth it.JMOTell me PS&B, does the Clay Smith maonage to somehow over come the fact that the NEW Mellings is a diiferent casting that before 1995 GEN motors, and that the iron SEEMS to be lacking for the OLD days. Does he have a special casting all his own, or is he blueprinting the same casting I can buy? Just curious!
The proof is in the inspections..... I have inspected about a dozen 10777, (discontinued screw in pick up type), and the 10778, 10778C pumps... They have ALL been right on the numbers. You'd think ANY quality pump would check out well, but most do not..... The "C"s are a little loose for a pleasure boat due to lower idle pressure, but they sure work well in high RPM applications... Having axle support in the covers adds a great deal to their ability to remain straight under heavy loads. You'd be amazed at how far those shafts flex with no lower support.... I also like the idea of a pipe plug in the end of the bypass chamber. No more little roll pins to mess with. Both of those pumps come with two bypass springs to choose from.. Oh, and the covers are precision located with hollow dowel pins in two cover bolt stations....New select series Melling is a nice pump for an iron OEM style pump. Comparing that with a billet pump is appls 'n ar'nges.
They all pump oil Wags.Am I a retard? What do the 10778 and 10778C do that a 77HV won't ?
I agree with Wags 110%! Why change what works. I have never used anything other and never had a problem. By the way Wags he has an aluminum rod build. MarkOh, boy... here we go. It is going to get good... I'll start.
Oh, you would be better off spending your time and thoughts making sure you have the right bearings, and bearing clearances.
Oh, steel rods I assume?
Never used the sportsman pumps but have run the pro pump. They are not a "bolt on" deal. They tend to want a BIG pan (mine was 16 qts) and a LOT of attention to oil drain back (no screens in the valley, additional drains on the back of the motor, etc). Also, if your boat is flywheel forward, the pickups are a bit of a bitch since there's 2 suction inlets into the pump. Nice pumps but you need to pay attention to the details.Any opinions on the TITAN pumps? They are offering a "sportsman" series since I used one last...
With the old style pump I would say it wasn't necessary. Today if I was running an iron pump, that brace would be on it. Also, if you look at the mill cut for the hold down bolt. It wouldn't be a bad idea to put a radius in the bottom of the cut up against the pump body. It would be nice if they used a cutter with some radius on it. Its just begging to break right in the ditch. Notice the flat milled bolt pad. This is a Milodon pump that broke in the first race after we installed it.Been wondering if one of these might be cheap insurance?

Depends on the build but these day's I'm pretty keen on the 10778/10778C pumps but also had good luck with the standard M77HVs for mild performance deals.
