Grumman Canoe parts

[martentrapper]

I have a grumman 19 ft. square stern that spent too much time on it's side under a snow load. The cross pieces/spreader bars, whatever you call them have bent under the load. The fore and aft bars I can probably live with. Middle bar should be replaced. It could be repaired by welding but would prefer a replacement.
Are parts available?
Thanks

If nothing esle, I'm pretty sure any of these aircraft mechanic/A&P?sheet metal guys at any of the general aviation airports (Merril, Lake Hood, Wasilla, etc) can fab a repair part (won't look factory but will work, using some scrap aluminum and a brake shear/press.

Are you talking about the thwarts or the ribs? Marathon makes the parts, the rivet pattern on the ribs has changed, which is unfortunate.

[martentrapper]

Thanks guys. I'll check with Marathon for new parts, and see if I can rig something to repair the center cross piece for this year.............it's not a rib so I guess it's a thwart.

making the repair your self an just reenforce what you have now will not look great but it will support the canoe as that is a soft part I bent the one on mine a few times when I carry it very far SID

Ended up fixing it myself. I am an aircraft mechanic, so have access to sheet metal and rivets, as well as tools. Turned out pretty good. May buy a cross piece still. That will wait for next year.
Thanks for the help!!

Darn, I was afraid you'd ask that................haha.

Here is a pic of the whole canoe and motor:


Most of the repairs were on the seat and in the seat area:


The seat and center cross piece were both removed.I repaired one side of the seat with a large patch. Repaired the support under the seat and reattached it to the center seam of the canoe, with sealant in the holes the screws went in. I also had to repair the top of the seat support piece.
The center cross piece was removed and straightened in a press. The one end was reenforced with 50 thou aluminum on top and bottom and screws/nuts.
The fore and aft cross pieces were straightened in place with bar clamps and 2x4s.
The whole canoe got a good pressure washing and scrubbing inside and out to removed dirt and sooty deposits. Don't know where the soot came from.
Hopefully the pics show most of what I described.
I'm sure the cross pieces are still weakened, but if I can baby them enough for this season, they should last.

looks good to me, you can run a 15 HP 2 cycle on it with out any problems, except the prop sticks down a lot an you will need 1 1/2 tp 2 FT of water
to travel where you work with metal you should make a lift it is a must if you run shallow streams there are a few in Fairbanks [ I IHINK ]
look at it an make one [ out of production have to copy what they have ] if you were in Anchorage I would let you look at mine an go from there
SID PS you can raise the transom up 4 1/2 inches an it will help a lot, I did it an run for 5 years that way ,
the one thing you do need to do is get & ENG that don't have a sheer pin in the prop [ it will break at the time you need it the most ] see back wright up's on it on this forum see you on the river

[martentrapper]

Had a 15 on it for years. It died after over 20 years. Have seen lifts on others. Good idea to make one. I'll look in to that.

I am running 30 + years on my 15 but still going strong got a new 10 HP 4 CYCLE have not tried it yet but this fall I thinking

How's the weight on the 10 4-stroke. A quiet motor with better mileage would be sweet. A guy could almost motor right up to the game..........haha!

[Sid]

81.5 lbs for 9.8 HP 4 cycle TOHATSU OR NISSAW ARE ABOUT THE CHEEPEST & LIGHTEST MARINER on this FORUN can supply the all that information on HP an weight , one of the new box stores that sell's Boat stuff in Anchorage has a propain outboard that looks good
