1959 gale seaking, prop seal???

[zuke]

i have a 59 35hp gale seaking... i am getting ready to go to the lake. i have posted before about lower unit taking on water... now it only leaks behind the prop... can any one tell me how to replace what ever seal is down there? and how hard it might be, and do i have to take the lower unit completely apart?<br /><br />thanks for any help in advance...

You can remove the end cap to replace it, but I really strongly advise a complete reseal. They're all worn. Put a good one in and another one will be the leaker. Rebuild the water pump as long as you're there anyhow. It used the same gearcase that the 33Hp Johnson used, any year. Go to johnson.com and you'll be able to look up the kit.

Re: 1959 gale seaking, prop seal???

i started to take apart the lower unit by the prop to see if i could see where exactly the thing was leaking from. behind the prop there is a plate with 2 holes in it, and it appears the lower hole was leaking oil, and this appears to be the only place its leaking... is there a special tool that i need to take this plate off or is there something special i have to do to take that portion of the lower unit apart to replace the gaskets?

Re: 1959 gale seaking, prop seal???

There is supposed to be a shaft seal in that plate for the propshaft. The factory seal had a copper jacket and a stainless backing plate. Is the seal missing?<br />The two little holes are used to push the seal out. You insert a little dowel through them and tap it out with a hammer. I find they're often stuck and the dowel just punches through. When that happens, I massacre the propshaft seal from the inside and remove it with needle-nosed pliers.<br /><br />Is it possible someone once tried to replace the propshaft seal, punched through it like I said, and gave up? Perhaps they tried to plug it with something?

Re: 1959 gale seaking, prop seal???

i think the seal is missing, but im not sure how to tell, do you know where there is an online picture of how to take this portion of the lower unit apart? as my book is only a mechanics part book, and it only shows the exploded views and gives no insight as to how to dismantle... <br />and if i take apart the whole lower unit, is there anything that i might mis-align or mess up by taking this apart? i belive its just the main screws and the shifter coupler that need to be taken apart... but is there something that keeps the drive shaft connected to the gear deal down there or does it just slip into place? i think im gonna take this all apart and just replace all the seals/gaskets i can see. and i have allready purchased an impact screw driver as i believe one of you recomended on one of my other posts, can i use this tool, or should i be wary due to the aluminum housing???<br />thanks for any help you can give...

Sorry, off messing with boats. <br /><br />Use the impact screwdriver wherever you find a screw that's the least bit difficult. It will not harm the aluminium, but occasionally it'll tear off a siezed screw's head. But you'll have to do some serious banging before that'll happen.<br /><br />Simple instructions are, drain lower unit, remove from outboard, and remove the water pump & wear plate. After that you'll be able to pull the driveshaft right out of the lower unit. Turn the lower unit on the flat you have now, and proceed to remove the phillips screw from the side of the skeg, and the nine screws that hold the cap on.<br /><br />After that, pop off the cap. Then note the position of everything inside. There's no alignment in this l/u - everything is machined to fit exactly. Some of them have a shim in between the pinion and the pinion bearing, but you would have to press out the pinion to find it. And that's only on some cases anyway.<br /><br />Sorry for the crappy pics, but this is what you should see:<br />

<br />

<br /><br />First pull the shift shaft all the way through, and lift up the propshaft with all the gears & bearings. <br />Underneath all that is the pinion gear. Just pull it out. Now you've got all the important stuff out. There are a few seals you want to replace whenever you take it apart. The driveshaft seal, the propshaft seal, the shift shaft seal, the o-ring around the propshaft seal carrier, the little o-ring on the shift yoke pivot screw (phillips screw on the skeg), and the spagetti that runs around the cap. None of these are re-usable.

Re: 1959 gale seaking, prop seal???

when you take that lower unit part off, is there something other than the shifter coupler i have to take apart? does the drive shaft just slip off?<br />and is it pretty easy to put back together?<br />should i take all the seals out and take those down to the shop so he knows what i want? and what kind of sealant should i use when i put the spaghetti back on?<br /><br />p.s. thank you so much for the pictures... i think they will help a lot.

Re: 1959 gale seaking, prop seal???

The driveshaft slips right out of the crankshaft. Unless it's corroded together, in which case you end up driving them apart with hammer driven wedges. That's why it's important to grease the splines at the end of the driveshaft and replace the o-ring there if it's worn. Here in the Atlantic, we frequently service the water pump. Part of the reason is to grease those splines.<br /><br />For putting it back together, the tricky bit is to get everything to line up. The driveshaft is not much trouble since it's guided into place. You sometimes have to turn the flywheel or propshaft a bit to get the splines lined up. The trouble is, you're trying to line up the water pump tube and shift rod at the same time. <br />If you can get some help at that stage, it's really valuable. Otherwise, use a long screw to hold the lower unit to the rest of the outboard, and wind it in as you get things lined up.<br /><br />Depending on the shop, you should just get the kit. Usually my propshaft seal doesn't come out in one peice, and the shift shaft seal will be deformed. I've got a parts list for a '57, which should be the same. Email me at Paul.Moir@gmail.com for it if you need it. But if the shop deals with aftermarket parts, Sierra 18-2686 fits all the Big Twin manual shifts back to '55 and has everything you need.<br /><br />The proper sealant is Marpox/Boat Armor 1000 sealer but it's sometimes hard to find. The shop owner may have a good recomendation. I used to use and recommend Permatex 3H aviation sealant, but someone here recently had a lot of trouble with it. He used Permatex Motoseal Grey in the end. I've had good luck with that product as well for lower units.<br /><br />Good luck!
