Building twin outboards for my Convincor

[dream4ta]

They make pullers that you might be able to rent out your way with being in a big boating area. But looking at that shaft i would vote for some blaster for a few days before you try to hard. if you cant find a prop puller you might be able to hook it with a 3 jaw puller and pull it off without any damage! That shaft looks pretty rusty tho...

That and get a MAP gas torch. It's like the little blue propane cans but yellow.

Thanks guys. Concerning the map gas: Would I heat the shaft or the prop? Seems to me like I'd heat the prop a little bit trying to get it to expand and then pull it off. Or would you heat the shaft trying to get a little bit of movement between that and the prop?

 

[atc250r]

The prop but now that I think about it its probably got a rubber hub pressed in so I don't know how much good that will do.

Question for the Checkmate Team

If I'm going to try and run this on a hose or a tub of water, is there a gadget one can buy to plug into the motor to act as the key and throttle? Or should I just pickup a used control box off Craigslist?

 

[atc250r]

Throttle you can just push and pull by hand. I'd set up a rocker switch to turn the ignition on and off and a push button switch to crank it.

I can send you a lock cylinder and key if you want to mount it to a piece of plywood. I still have the dash assembly from the Maxum I cut up.

 

[DropTop5.0]

I guess I'm not the most useful tool in the shed. How do I go from this plug to getting something to turn over.

 

[demag67]

That is the fuel line disconnect. You can buy that connector at a west marine or boat parts store.

I would prop the gear case upright with the prop shaft facing up and soak the propshaft/prop with PB Blaster/WD-40/Rust Buster/CRC/etc. for a day. Then smack it with a mallot. You can hit harder than you think without damaging anything. Use a piece of 2X4 between the mallot and the prop when smacking the prop...

Worst case scenerio is that you may have to take a torch and heat up the prop hub while trying to hammer the prop off...

If I was trying to get that prop off, I would face the prop and shaft vertically, wrap a ratchet strap (non stretching strap) around the prop a few times, and attach it to the ceiling or a rafter. Then I would make sure all the weight is on the strap. With the prop nut threaded almost all the way so the end of the shaft is not protruding, I would give it a few raps with a 2.5# sledge. Just like popping a balljoint.

Good luck

How about using a gear puller?

 

[RNGRDVE]

^^^that sounds like a solid plan.

Edit SCT responded at the same time I was commenting to Il's idea. But both sound like good ideas.

Droptop, I'm just curious... how come you didn't buy the motors from jerry when you bought the boat?

 

[DropTop5.0]

Available cash at the time. I still had my Pulsare and I hate to part with too many Benjamin's at one time.

I thought that we discussed heating it earlier in the thread.

Haha, i know what you mean, I had been kicking around buying that boat for nearly ten years. I offered him 12500 cash this summer with the motors and he shut me down. That was all the cash i had on hand and was getting married in september, the 20th. I figured I'd buy it this fall when i saved a little more. I think you bought it the day of or right around my funeral,,, i mean wedding.

 

[demag67]

If you cant get the prop off. Make a 50/50 mix of dextron mercon transmission fluid and acetone and soake it with that. Worked wonders on my motor from the salt water corrosion.

You still working on this?
Summer right around the corner. Better hustle! See ya soon.
