Goodyear SeaBee

[F_R]

Re: Goodyear SeaBee

Been going thru the SeaBee last week or so everythings looking good; powerhead is clean and in good shape, ignition parts are pretty new, went thru the lower end last night( in good shape with no issues) pretty simple lower end.
The only question on the leg is for the waterpump housing, it dose not appear to have a seal in the upper housing to driveshaft? Still need to clean carb body and reassemble with the gasket I made, and clean fuel tank then reassemble motor. One more question, on the carb body where the reed plates mount to body do I have to seal the threaded holes on the outside?
In many of the pics I have seen of other carbs for this motor you can clearly see a sealer of some type ( also mine was sealed too).Landscaping wiz & Ohm116 you guys still around? Did you guys get them motors runnin'? I would like to hear how you both have done. Thanks to all who have given advice so far.
Talk to ya later. Larry

No seal in the pump housing.

The reeds screws are supposed to be sealed. But the tiny bit of leakage won't amount to any performance loss. What does matter is if one of the screws comes out. You can then kiss the whole thing goodby.

Another caution: The hex bolts that hold the gas tank bracket--if they are too long or you leave out any washers, the bolt goes in too deep and hits the reed plate flange, bending it. Then it leaks badly.

Re: Goodyear SeaBee

Thanks F_R for responding.
You seam to know these motors pretty well. What do you recommend for the reed plate screws? I have red loctite, would that work? In reference to the gas tank bracket on this motor there were no washers on any of the carb bolts, I used the same bolt in the same location and didn't notice any bent plates during rebuild. Now when you say it will leak badly, do you mean an internal fuel leak? I did end running the motor today with a few issues I will address further down. Anyway when it ran today it seemed to have some raw fuel coming out of the small drain tube (bottom of power head port side) at least I assume that is a drain. Should I pull the carb and check?

So like I said I ran this motor today, started right up with just a touch of starting fluid, performed cylinder drop test, its firing both cylinders. Seemed to run real good except for the issues below:

Fuel shut off leaking (tried tightening the packing nut? and the lock nut? to no avail) carb has been apart before, card gasket was gunked up and the fuel shut off nut was chewed up. Any advice, maybe a retrofit?

Seemed to run hot, I didn't run it long, couple minutes at a time. Starboard engine cover (exhaust?) was pretty hot, hotter towards the top, could do a 3-4 count at most. Port side cover not so hot, nor the head. Dropped the lower yesterday impeller was like brand new.
Could not see any tell tale or spray. There appeared to be some water around the top pivot joint, I don't know if that is supposed to be there or not.
The 3 or 4 angled cuts above the lower pivot, is that supposed to be exhaust, water, or just a drain for the leg?

Neutral clutch wasn't working, when I had the leg apart there wasn't positive engagement between the lever and the clutch spring. It worked before I pulled the leg so I left it alone. It may need to be tweaked a little bit or I don't have the cable tight enough. Any advice?
Looks like the leg may have to come off, I will recheck the impeller. Is there a way to check from the water tube (with leg off) through the powerhead to look for blockages, maybe compressed air?

By the way, the white plastic carb float worked like a charm even being 1/4 inch taller than the original, I drilled center to fit the needle, it had a molded hole with a nub in the center. With an interference fit I just slide it up and down to adjust, time will tell if it stays tight.

Sorry such a long post, aside from a few issues I am pleased how it ran, seeing how it hasn't ran since Jimmy Carter started his term. LOL

Thank for any advice anyone can give. Larry

Re: Goodyear SeaBee

I knew I would for get something, it seems to me that the markings on the side of the carb for the idle screw are reversed, as you turn in(clockwise) the idle screw it opens the throttle valve richening the fuel, and turning out the screws allows the valve to close leaning the fuel.

It is marked RICH counterclockwise

LEAN clockwise??? Am I missing something? Bye for now.

Re: Goodyear SeaBee

If you open the throttle valve it well let in more air and cause it to lean out and vice verse.

About the neutral, on mine the original lever in the LU was broken and I was able to get a replacement. Also if you do not have a paper gasket between the LU and the impeller plate it well cause it to lock up.

There should be water coming out of those 4 slits in the leg, this is where it discharges the water, it doesn't sound like your getting water flow, you might have a blocked line or a broken line, which might explain the water around the pivot.

Your shut off valve problem is probably the rubber packing in the carb but it might also be due to a previous owner not removing where the packing nut was staked and ****ed up the treads, like mine is.

Anyway hopefully that helps.

Re: Goodyear SeaBee

WOW!! I can't believe I'm just finding this thread!!

Awesome, another 5hp Gale!! It seems to be in pretty good shape too. You're in good hands with ohm116, steelespike, and F_R. My motor would be a lost cause without them!

I know I'm late to the game, but if you still need that carb gasket send me a PM. My "parts" carb came with an extra one and if you can use it, great.

Looks like you're way ahead of me with yours, mine is still disassembled and I'm waiting on some "new" parts. Keep us posted!

Re: Goodyear SeaBee

Welcome aboard guys! Maybe when all is said and we will all have running

50 some year old motors, lol. Hopefully F_R will chime in soon. I'll keep y'all posted.

OHM116, is yours runnin'? good luck guys. Larry

 

[ohm116]

Re: Goodyear SeaBee

Oh yeah mine has been running for months now, just has a few issues still, I well look into getting it buttoned up next week though as I am really busy this week. I have a better tank on the way for it and I need to redope the float and it should be running good.

Re: Goodyear SeaBee

Good job ohm116, Hey do you remember how hot yours ran?

I solved the shift issue, still have to seal the carb & check the reed plates.

But the cooling has me baffled, come on guys I need some ideas.

Like, can I use compressed air up the copper tube? Or do I need to seperate

the power head from the extension to see whats going on?

Thanks. OH btw Go Red Wings!!!

Re: Goodyear SeaBee

I get just a luke warm spray out the slits in the leg, never gets really hot. I still think you are not getting water to the powerhead.

 

[tmcalavy]

Re: Goodyear SeaBee

Like ohm said, you'll only get a fine mist/spray out of the slits on the back of the leg. If it's running too hot to touch, you need to investigate for cooling system blockage...got any spray at all when it's running?

 

[Thunderhawk]

Re: Goodyear SeaBee

When I ran it I don't think any water was coming out of the slits, the only water I saw was from the upper pivot joint, (I think?). Anyway, fixin to go pull the lower now. I keep ya posted. Thanks

Re: Goodyear SeaBee

I pulled the lower end off last night, powerhead must be full of sand because there was a lot sitting on the pump housing and inside the exhaust tube. So I guess I'm gonna try to push water up the tube to rinse it out. We'll see how it gose. Thanks. Larry

 

[tmcalavy]

Re: Goodyear SeaBee

Plumb the inlet tube going into the powerhead to the garden hose and flush it out for awhile.

 

[ohm116]

Re: Goodyear SeaBee

Just to hijack the thread, my "New" tank arrived today and it looks good, it is actually a SeaBee tank so it well need paint and decals to match the rest my motor. I am going to try and pull the old one and the float to redope it and hopefully early next week after the dope dries I well put it back together and make a video of it running

 

[Thunderhawk]

Re: Goodyear SeaBee

Thats great, hope your tank is a nice one. Can't wait to see completed pics. I tried to flush out mine last night with the lowerend off. I didn't get much out of it, so I reassembled it. I'll run it after work and see what happens.

Was up Landscapewiz hows yours coming?

Wish me luck. later Larry

I'm waiting on a recoil starter spring to be delivered from Kansas. Once I get that it should be ready to bolt everything back together and fire her up. Oops, I forgot I still need to clean the carb too. I've been putting that off for a while now - not my favorite job. Maybe I'll take care of that this weekend.

I've been meaning to ask you, what did the original impeller look like? I figured sucking up all those pebbles and sand would have put a hurting on it.

Re: Goodyear SeaBee

Hey Bob, don't sweat the carb, not much to it. As far as the impeller goes it looked nearly new. So I ran it again today after attempting to flush the powerhead, trying to figure out the lack of cooling, no go still getting hot on the starboard side(exhaust?). So I pulled the powerhead figuring it or the manifold tube would be packed with sand, nothing. It looked pretty clear, now what? So I started poking around, here a my most current questions;please see pics.

In the pics it shows the water ports on the manifold, which obviously line up with the ports on the bottom of the powerhead. Q; is one a inlet and one an outlet? The reason I ask is it appears that in the powerhead the water jacket is connected to the exhaust port???? I blew some compressed air (lightly) and smoke into the waterjacket and it comes out the exhaust port. Sooo I'm a little miffed.
Also by poor design the powerhead mounting bolts extend into the waterjacket, causing the ends to corrode. So you know how it goes when you pull a rusted steel bolt through aluminum, not pretty....

So that is where I'm at in the Seabee saga, any ideas or discussion would greatly appreciated. Bye for now, Larry

Re: Goodyear SeaBee

The cooling water exhausts through the engine exhaust, just not sure if it does that through the block or lower down in the leg, you might make another quick separate post on this to see if someone that isn't watching this thread might know.

Re: Goodyear SeaBee

Please disregard eariler post about "waterjacket connected to exhaust port";
I think I may have fallen and bumped my head LOL....serioulsy though still scratchin my head about the lack of cooloing. So far everything is clear.??

I know kind of a stretch. later Larry

Anyone ever have problems with overheating runnin' in to small of a barrel?
