I have an 8hp Bukh saildrive in my boat. There were original equipment in Laser 28's and a few other 80's boats. The model# is DV8SME. I suspect yours is the same. These are good, simple engines but parts availability is tough. You don't say where you are, but there are to my knowledge two North American distributors for Bukh parts. North Jersey Marine in New Jersey and Crinmar in Ontario. Crinmar is DefaultHomePage
. North Jersey Marine doesn't have a website (actually there is another North Jersey Marine that sells bass boats, don't be fooled). I've posted contact info below from an email the owner sent out to customers last year. In the past I have been able to get good advice from him regarding engine problems. However, I've been waiting for a parts order from him since late January and found it impossible to get him by email or phone. It's a little hit or miss.
Your third option is to order parts from Denmark (where Bukh is still in business). See: LSM Diesel A/S - Denmark - Marine Motor Sale, Spares and Repair
. This is a Danish Bukh distributor with an online parts catalogue with pricing for some parts. I suspect shipping will be expensive, I haven't tried this route yet, but may soon.
Coincidentally, the part I'm replacing is the saildrive bearing and seal. You may be able to replace the seal without pulling the bearing, not sure. In my case the bearing was shot (corroded). I had to split the case to remove the bearing. Bukh parts are outrageously expensive. Think of the most you figure the part could cost and multiply by four. Good luck!
