Hey all,
I have a '61 10hp Seahorse that is performing rather strangely.
Engine starts great, 2nd or 3rd pull in cold weather (i duck hunt). Under heavy load (14ft rivet deep-v, decoys, 2 guys) it runs fine at lower throttle. When I try to give it some gas, the engine starts racing but goes nowhere.
First time it happened I thought it was the shear pin, but no dice. I noticed that the existing shear pin was stainless steel! :/ Then I thought that the teeth on the gears in the gearbox were worn, but they looked fine. Also the spider gear connects to the drive shaft perfectly.
When I opened up the gearbox I did notice that the previous owner didn't have a real gasket on neither the gearbox cover OR where the lower unit disconnects.
I'll of course order gaskets, but does anyone else have any ideas?
