Then without a doubt the engines I would reccomend are either the OS .55AX or the OS .65AX. That .65 is an amazing workhorse and I am using one a cross country floatplane that carries 72 ounces of fuel and it handles that load with authority. It also has demonstrated to me unprecidented reliabilty. There is a very real reason they are more expensive. Also consider there is a reason why tower no longer sells the Tower rebranded chinese engines. You only need to use your imagination. My suspition is the actual manufacturer was the same company that produces the SC brand sold in the UK and the asian market as well as a number of other rebranded engines.
