Anyway back to the main question: Will this outboard be OK running on TCW3 oil or must it be TCW2? Any advice would be appreciated. Thanks!
Nah, needs TCW2. TCW3 can't take the temps of an aircooled motor.
You'll find that Crescent closer to a 4hp than 5hp. I used to have one-they are an old Gardner lawnmower powerhead bolted to a shaft.Noisy as hell but mine was very reliable though.
Incidentally, don't run it out of water. It DOES have a water pump on it-used to cool the leg. The leg will get quite hot if the pump is dead.
Need spares,consoles,consumables,hire,training or even a new boat?
