Hello all,<br /><br />I own a 2000 Glastron SX-170 with a 2000 Johnny 115. I currently have a OMC 14 X 19 alum prop. Its pretty dinged up. Is there any advantage to upgrading to SS??? If so, what model. I usually just use the boat for watersports, tubing, kneeboarding and wakeboarding and general lake crusing. The current alum prop seems to be just fine for hole shot and top speed. I can get up to around 46 -47 mph trimmed out. Just wondering if its worth the $400 buck a roo's. I live here in Minnesota and boy I sure miss by little guy.
