Prop for 8 HP Tohatsu and 26' sailboat
I'm thinking of getting a high-thrust prop for my boat's outboard. The motor is a recent 4-stroke 8 HP Tohatsu and the boat is a San Juan 7.7, 26' LOA, 20' LWL and 3200 lbs design displacement. It has the standard 3 blade 8.5" x 7.5" pitch prop. Tohatsu has two high-thrust props available for the engine, 4 blade 8.7" in 5" and 7" pitch. Would either of these props be a better fit for my boat? And if so, which one?
