Re: Small Outboard Care
Other than using Ethanol Free and a double dose of BLUE Stabil in the gas, most maintenance is done at the end of the season, which for us in around October 1.
I defer to my mechanic as to when he wants to do things by keeping careful records of use. BTW, I have 6 hp 4 stroke Tohatsu that I am still breaking in after its predecessor, a 5HP Honda blew a head gasket.
Since you have an older model, you carb jets are much wider in diameter especially since there is oil in your gas, and you will probably have less problems with ethanol than we do. However, remember than ethanol is a very powerful solvent(like the blood in the Alien Movie creature) and it will dissolve all plastics like seals and gas tanks, and that it will collect water and add it to your gas right out of the air. We used to have additives using it to absorb water in the gas line of cars.
