I will check out my motors more this weekend. I haven't done much personally to them since I bought the boat. I enjoyed the luxury of the marina doing my maintenance for me. I have more time and less moola now and intend to resume taking care of my boat myself. I may even have manuels for the motors and genset on the boat. Thanks for your help and interest. I am on the great lakes, not far from ya'all. I dock at Gem Beach on Catawba. Is ther public access to Venetian I would love to meet you and the "professor" and look at your boats. I'll bring the beer. if your ever around West Harbor, My slip is just a few paces down the street from the Chart House Bar at our marina. Best regards, Chris
