Just closing on a 36. Surveys went well but as expected for a 2005 there are a few irritating things to fix. Air horns on the hard top don't work. I could hear the air pump but nothing came out. Starbord wiper doesn't even touch the glass HAHAHA. Fresh water pump #2 isn't working and stuff like that. Otherwise she is good to go. Hoping to find good information on this site. Thanks Rick
Congratualtions on your purchase. You will be more than satisifed with your Tiara. I own a 2003 38 Open and had a 1997 31 Open prior to the 38.. WRT to the Air horns.... It's not a big issure repairing them based on the problem you described.... Assuming they are the same s mine, Fultone twin air horns you can purchase a repair kit that provides new diaphragms, covers, and screws.(Fultone Repair Kit Part No. 2132311). Need to clean and make sure the seats where the diaphragms are smooth/clean. Should resolve the issue with the air horns.
That's an incredibly short list for an 18 year old boat! Congrats!
