You might check with the local U.S. Power & Sail Squadron in your area, as they have a class called Engine Maintenance.Hey guys, I"ve been lurking around this board for a few weeks now and have found it extremely informative! I will be a first time boat owner this winter. I'm looking to buy a 30'-35' boat. I was wondering if you guys knew of any good seminars or workshops on diesel engine maintenance and repair. I live in NYC so would prefer any place located in the tri-state area. Thanks a lot!
