I can't thank you enough for taking the time to reply! So here is where I am at. For some reason I have the RV-20 which has been discontinued for some time. I drove it over to ft lauderdale to trasmission marine after speaking with a mechanic who was knowledgable about Walter v-drives. He mentioned it is quite large for this model Pearson and said he would give it a look and tell me what he can do. Then i received the great phone call from him asking if it came from a sunken boat. So he is saying it would need entirely rebuilt in which he would basically only keep the housing, costing about five hundred less then a new one. A new one he estimated at 3500. He said when he opened it it was just a ball of rust. I am planning on verifying this of course before continuing to attempt to fix the problem. Though my gut reaction is that he is honest and this is what I'm stuck with. I guess the questions now are: if I buy new do I need to buy a unit that matches the size of the Rv 20? Are there simialar units out there that have internals parts that would make this still achievable at a lower cost. Should I attempt to find a used Rv-10? Again I can't thank you enough for sharing some knowledge with me. First boat i have owned with a v drive. It scared me a little prepurchase and has developed into a self fulfilled prophecy.
