Is the Sherwood on the engine mounted with bolts through a flange, or with bolts through clamps?
If a flange, you can get a -16 and grind the flange to fit. Go to a Kabota dealer and buy the gasket and use it as a pattern to cut the flange and drill the bolt holes. It is brass and shouldn't be too difficult to grind away. I just don't have a grinder.
If it is held on with clamps the -908 is a drop in. You can use the -908 on the flange mount version, but will need to buy the pricey mounting kit which includes the clamps and bolts.

I'll have to go look closer, and take pics. The good news is that this is not something I need to do right now, so I've got time to get educated on this. The Sherwood in the boat right now has a new impeller, only has about 20 hours on it.
easy fix.... i got a 16 last year and cut to fit with a hack saw..... made gasket for drill instructions..... real easy fix and very happy to be rid of the sherwood.... on my xpb
Makes me laugh. What don't manufactures get !!!!! The N202M-908 is a great new pump but they are going for the CASH GRAB.:naughty: If they brought it more in line with the price of the N202M-16 they would have a HELL OF A LOT more sales than there getting. As soon as I fined a supplier here in Ontario I definitely going for the modified N202M-16.

Sluggo, from what I've read here, the XPB has the pump on the starboard side of the engine (per Tom's picture and many others), the XPA (and the M25 and M25XP) have the pump on the PORT side. If yours is on the port side, then, yes, it will. That's what this and many other C310 Forum posts have been discussing, thanks to Jesse's article.
So you just take the -16 and grind off all the mounting flange EXCEPT for the clamping ring to make it into a 908.
Should be a resale market opportunity in that!!

Or maybe take a 16 to local machine shop?
Would using the 16 bolt holes make for a more secure installation than the 908 clamps?
Also less work.
Ok, finally took a couple of pics of the Sherwood pump on my -25XPA. I'm hoping the -16 pump will bolt right up without cutting/hacking/grinding.
Am I correct?

What I meant to ask is; buying the -16 over the 908 gives two mounting options. One can either grind away a little and use the holes in the flange to bolt the unit to the engine or grind away a little more to make it into a 908 flange and use the exsisting clamps to secure the pump. Both appear to work.
Somehow the former seems more robust?
However the holes in the -16 flange don't exactly line up on the M-25 XPB. I cannot attest to the other models. You will need to elongate them for the XPB. There is a post somewhere that says a Kabota gasket makes the perfect template.
Good news! That looks great. You should have no trouble with installing an Oberdorfer. Even if you have to grind an edge or match a bolt hole pattern. All the info you need you already have (or it's here on this 'site).
