If I read your model number correctly it is a 1991 model. The kits sold here at IBOATS are 18-3395 without housing. And 18-3396 with housing. Yamaha numbers are 61A-W0078-01-00 without housing. And 61A-W0078-A2-00 or 61A-W0078-03-00 with housing. It appears they used the same pump for many years. So you should be ok.
