Help! Heavily corroded pump removal

This is driving me nuts! I can't get the pump to budge! I've tried splitting the stator from the wear ring, tried separating the wear ring from the intact duct....nothing. I've been using a very slender prybar and hammering it between the castings and I can't get anything loose. The bolts that hold the wear ring to the hull are removed and I'm able to get the pry bar between those mounting tabs and the hull, so I know that's free. When I pry those tabs I can see the whole pump/intake duct assembly slightly moving but I can't get anything apart!

I was thinking about getting some ready-rod and making a puller to pull the pump directly rearward, but I'm open to any suggestions at this stage!

See the pics of what I'm working with:

The pump/intake duct assembly is from a Yamaha Waverunner 3, but a factory install in my Boston Whaler Rage.

You need to heat the aluminum some and it will help. The pump cone can be removed and back of driveshaft is threaded, you can get large metric nut for it and weld attachment nut to slide hammer and pull it. That pump is going to be trash so you can beat on it.

I've had to pull the motor and use a air hammer to push the driveshaft out of the midshaft from the front side.

I've also had to cut a driveshaft in front of the pump and then replace the midshaft and drive shaft. I was able yo salvage the midshaft housing. If time is costly for you this could be a time effective way to get her done because even if you do get it to budge you may still be replacing the driveshaft and midshaft.

Thanks for the suggestions so far. I'd rather not do anything too destructive just yet, so I won't be cutting the prop shaft.

I made a crude puller last night and gave it a try but it didn't come apart yet. I sprayed penetrating fluid on it last night and I'll try again tonight with some heat added to the process.

Get a blow torch and heat the poop out of the mating areas - tap a pry bar into the pry lugs and it should go. Lots and lots of heat is the ticket. Be careful of the surrounding areas and have a bucket of water to hand just in case.

Sounds good. I'll give it a shot tonight!

Heat was the trick! Between the replies posted here and my own observations I realized that the pump I have is 100% junk, so I wasn't shy with the torch. I had my puller under tension and it took some good whacks with a mallet and the prybar but it came apart finally. The good news is that the shaft splines had plenty of grease on them so at least that wasn't holding me back.

Once I got the pump out I discovered that the top side of the stator is actually perforated due to corrosion, along with the vanes of the stator are totally mangled with corrosion and maybe damage from debris as well. Also, the wear ring was corroded and the stainless liner was no longer round...there were a few points where the impeller was making contact. You can see the edge of the impeller blade has a burr on it from rubbing the wear ring.

YES! this!

This boat could benefit a lot from a mag pump and a 701 topend!

And that's exactly what I've got in the garage, waiting to be installed! Stoke factor is high!

Used 701 61x
Brand new Solas stainless wear ring, mag pump, and exit nozzles with TRIM! (I hope this helps get the boat up on plane better)
Brand new Impros Hooker 9/15

And a whole bunch of new maintenance bits from JetManiac:cool:

I have been researching these boats for the past couple days after seeing yours and that seems to be the biggest complaint. Even with the 115HP OMC. I'm assuming yours is the 650 version if you have a fresh 701 going in it. I bet it would be a great conversion with a 1200 PV triple in it.

FYI, There's a 95 for sale in Charleston, SC for $3900 right now. His has the 115HP OMC drivetrain.

OCD, yes, my boat is the 650 Yamaha. I personally wouldn't own one of the OMC versions. Yes, the power would be nice to have, but even when new those engines were prone to overheating, and the cooling system doesn't completely drain so lots of engines were wrecked by freezing water over winter. Beyond that, the weight balance is all wonky with the big, heavy powerhead sitting right at the stern with the pump. The Yamaha versions have much better balance because the engine is basically right in the middle of the boat. Fuel is under the bench seat.

I would love to have lots more power in my boat but that's unlikely to happen without some major fiberglass work, for two reasons:
1. the engine compartment in the floor is quite tight around the existing twin, so a triple would definitely need some massaging
2. the stock engine mounts only really connect to the inner skin of the hull which isn't very robust. There's cracking around my mounts as it is....just from the fury of the stock 650! I'll post another thread to show the new pump, motor swap, and general details
