Hello I am trying to figure out what size/pitch prop I have on my 115 yamaha v4. It's a stainless prop the only marking that are on is 4336. What does that mean. I think I need to try a new prop the max rpm are 4700-4800. What I read is that should be around 6000. It also uses a ton of fuel way more that it should. Thank you for your time.
