I have two 4hp Nissans, long shafts, one on my Seaward Fox and the other one on my M17. One is a year old and the other is about 15 years old They work great, seem quite efficient and use 3.5 gallons external tanks,. Was just down in Key Largo and the Catalina 22 I used had a 4 hp Tohatsu with an internal tank. I think I put about 5 miles on it before I had to refuel.

Anyone have experience with Tohatsu / Nissan / Mercury? _______________________________________________ http://mailman.xmission.com/cgi-bin/mailman/listinfo/montgomery_boats When posting, remember that there is no privacy on the Internet!
