I have two NIB Lasdrop bellows style dripless prop shaft seals that fit a 4.5" shaft and 7.5" stern tube. One has been removed from the packaging for photos, otherwise they are as delivered from the manufacturer. These are very high quality, low vibration seals made in the USA and retail online for about $3000 each. I will sell as a pair or separately, please make reasonable offers via YF message. I'm getting out of the business and will be liquidating many parts and tools to start a new venture in July. Since the buyer will get these items for far less than retail, this is a great deal for a contractor who wants to deliver a low bid job to get established with a client.
