Tohatsu manufactures it's own outboards and also many of the outboards for Nissan and Mercury. I think below 30hp, the Mercury and Tohatsu outboards are basically the same engines and are manufactured by Tohatsu. So I don't think one needs to be concerned about the reliability of the Tohatsu engines. They have a good reputation for reliability. I'd make a decision based mostly on the local availability of service first and price second.jack keifer":3ri4wkfq said:Don't know about the Tohutsu but we have 310 hours on an 09 Honda 50 EFI and performance has been flawless. If you are running a single engine, I would suggest that reliability is priority #1, performance #2, and a few pounds weight differential no more than #3. Others out there have experience with other brands which likely are equally good. No matter the brand, I think everyone would agree that timely maintenance is the key to long life and reliability.
