craft is a 1962 Vietnam era PT boat. We are trying to remove the circular "brass" seal that holds the rubber cutlass bearing???, in place that the propshaft actually rides on. Does anyone know if it is screwed on (our 1st thought) No luck. Pressed on??? Heat,a chain wrench ect no go. Any ideas would be appreciated. Nick

One of the best solutions i've heard is to remove the prop shaft, spray the bearing area with Pb blaster, wait a little while and then call the yard mechanic to do the job !
If you want to tackle it yourself ?

Who manufactured the Cutlass bearing? They should have a drawing that will show how the retaining ring is attached...
I would think it should be hex head bolts into blind threaded holes, then the heads of the bolts would be wired together to prevent them backing out.

I bet there's a navy/dod manual on it...

I have a 1948-50 2 1/2 horse Johnson Seahorse. It runs great for about 45 min. and then stalls out. It can be restarted, with priming, but will only run for about a minute. Any ideas what the problem is?

need help on Palmer 9(?) HP motor, i can not turn it over by hand, turns a few degerees, then clunks. The propellor will not turn it either, it may be in gear but do not know how to disengage, there is a bronze d-grip that slides up and down, previous owner said it was to shift tranny. has not run in 15 years or so. should i pull it out of the boat to work on it or is there a way to determine the nature of "stuckness" easier, ie, pull the cylinder up? i would love to get this running, its in an old sailboat and would be great rather than a nasty new outboard-THanks- clayton

Clayton, Don't pull the cylinder. Yet. typically there is a flange coupling between the engine/reverse gear and the propellor drive shaft. I suggest you remove the bolts that hold the two flanges together. Mark the flanges befor you separate with a sharpie them so you can bolt them back together with the same relative position they have had for many years. Then you should be able to rotate the prop and the engine separately and quickly determine which has the problem. Can you send a picture of the engine so I can help you determine what model Palmer you have. If no picture can you describe the engine??
