9.9 Outboard
Hi Bob,I understand the Grampian 26 (1970)I own came with a 2 stroke Sears 7 H.P. motor. The former owner replaced the OB with a Farymann Diesel. I have a 23' Hunter (1986) down in Florida that originally came with a 2 stroke Nissan 5 HP. I replaced it with a 4 stroke Yamaha 9.9 HP. However, It required a new outboard bracket and beefing up of the transom to support the additional weight of the 4 stroke. The 4 stroke is a joy to operate. Great gas milage and very quiet. The Yamaha 9.9 is quite heavy. My question would be, will the transom of a Grampian be able to support the additional weight. I would be interested in hearing how you make out and what your final decision is.
