I’ve been out of the outboard game for a while now but I finally found a motor I’ve been trying to get for a long time- a torpedo tank Waterwitch. It’s in excellent shape overall and seems like it will run with very little work- great compression and spark. Only problem is it sounds like it has a bad rod knock, and all the rubber bits are pretty much turned to goo. I was wondering if anyone knew where I might be able to get parts for it, or if there was anyone I should talk to about repairing the rod if I can’t get a replacement. I haven’t torn into it yet but it seems to have very similar symptoms to the Power Products motor I just rebuilt that had a similarly bad rod knock.

Rare to find those in that condition.
They sold a ton of them so finding parts
shouldn’t be a problem. You need to get
in side to see what it needs. Maybe as
simple as having a machine shop refit
the rod to the crankshaft.

Thanks, I was really excited to find one in that kind of shape, just a couple dents in the tanks smaller than a dime and the gas cap is pushed in a little. Thanks for the link. There were also a couple other rubber parts that are pretty degraded, specifically a piece that connects the upper and lower pieces of the water inlet up to the powerhead, and another piece that seems to be between the water outlet from the jug and the exhaust manifold. Do you know if those are reproduced too or if there’s a fix that other people have done? Also, do you know if parts from a similar model will fit? I have the finned jug but I see the ones with the smooth jug (I assume later models?) on ebay like the 571.40, would any of those parts be interchangeable? I’ll have to dig into this thing soon but first I have a mini bike with a Clinton Panther to fix.

The other rubber parts are just pieces of
red hose. Its available but I don’t know the
source. As I can’t answer what parts cross
over I would suggest you search out parts
from another 10 model. Here is a link to our
classified’s where you can make a request for

Ok, I’ll probably be posting an ad as soon as I tear into it and check what exactly I need. If I can’t find a new rod I’m sure there’s someone in my general area that would be able to get it back in order. I’m just hoping the cylinder isn’t scored because I would assume a rod knock like that would only develop if it was run low on oilJuly 4, 2020 at 3:50 pm #207666
I’m in the process of restoring two of these motors. We had to pull parts from a number of different motors just to assemble two. I would take a close look at everything as you disassemble the motor. The water pumps are commonly worn out. When you put it back together be careful not to over fill the grease in the lower unit as it can squeeze up into the water pump and render it effective.

Would you happen to have any spare parts from the other engines in case I need something else? And if my water pump is worn out is there a fix for it?July 4, 2020 at 7:59 pm #207714
Ok, that’s giving me more confidence. I don’t think the gears are ruined because there’s very little slop when I turn the motor over. I wonder why since the motor is so nice that it has such a bad rod knock? I’ve had much worse motors that were completely fine. I think I’m going to tear into it this week. Just figured out the carb issue on my mini bike so this is my next projectJuly 5, 2020 at 8:26 am #207761
None of the gear sets we encountered were worn. In fact, every set was like new. I would not take anything for granted on your motor. If there was enough run time to wear the rods the water pump could definitely be worn.
That is one beautiful twin, Tubs.

I hear ya, Tubs. Neither my friend nor I have enjoyed working on these motors. It’s hard to stay motivated. I wouldn’t do another one. 1936 is a rare bird. I might be swayed by one of them. The powerhead arrangement is pretty interesting.
