    tube falling apart

    Hi all, I have a 10ft west marine rib. The tubes outer skin is separating from the tube. It looks like a hernia as the tube is popping out of the slit. I can slip my hand in between the two layers. It is still holding air (somewhat) but I am afraid that it will pop when filled. Any Ideas on how...

    bent shaft?

    Can anyone tell me if this shifter shaft is bent? It is off my 1975 25hp Evinrude. It is popping out of gear. I did take the lower unit apart. The forward gear does show signs of some wear where the clutch dog engages. I attached some pics of the rod and forward gear. Any info is greatly...

    Just a thought.

    I posted a thread dealing with my 1975 Evinrude 25hp. My forward gear keeps popping out. I was wondering if it would be feasable to get a reverse spinning prop? Would reverse hold the torque? At this point it might be cheaper than paying/ finding a forward gear.

    25 hp lower unit

    Hi all, I have a 1975 25hp evinrude. I want to know if I can exchange the lower unit with that of another hp. I also have a question in reference to the shift rod. The rod is bent towards the bottom. It looks as done at the factory. How can I tell if the forward gear pops due to a linkage...

    grinding forward gear

    Has anyone had luck using a dremel tool or the like to fix their forward gear. My 1975 25hp evinrude was jumping out of gear. I had no real adjustment to make, so I took apart the lower unit and found that the forward gear is worn where the dog clutch mates with it. I have read in other posts of...

    1975 25hp shifter

    Hi all. I am having a problem changing gears on my 25 hp 1975 evinrude. I start the engine in neutral then put it in gear. When I try to take it back to neutral, I have to turn the armature back so that the shifter can go back in neutral. I also have a part that looks like it would lock out the...

    I purchased a 25 hp 1975 evinrude 25502b. The crankshafts threads are stripped pretty good. mI guess someone put an airgun to the nut and crossed it down to about 3/4ths from the bottom. Does anyone know the thread size? I want to try using a dye to rethread. Will this work and what size do I...

    Leaky valves and latex

    Hi all, Just started reading the forum. I recently purchased a rib for $100. Of course it leaks. It leaks all over. I had to find the owner on the title because the title was signed but never registered by the second owner. Did that but that did not stop the leaks. I patched a couple of wear...
