If you are going to start pre-mixing, get a pre-mix bottle from a marine dealer or Walmart...it makes pre-mixing goof-proof and EASY!...tells you exactly how much oil to add to the amount of gas you just put in the tank...

Another hint... Through trial and error I've learned a spot on my gas gage where, when the needle is at that point I know that I have room in my tank for 35 gallons of gas. I put a small piece of electrical tape cut like an arrow head on my gas gage pointing to that location. When the needle gets to that pointer I know that I've got the room in my tank for 35 gallons. That way I'm always mixing oil for 35 gallons and my ratio is never rich or lean... Anything over that amount that I want to put into the tank I mix outside the main tank it a 5 gal gas tank, then I pour it into the main tank.

all good info!! you will need also to make sure you are propped right!
Depending on what you want. I used a 15 x15 1/4 and gave me great out of the hole with heavy loads, others use a 17 pitch fir more top end, its up tp you, but the Tac will get you a general area and you can twek as you want. most shops will lend you a test prop to try before you buy. and a good shop wil be almost on the money if you supply all info, like weight, horse power, top no top ect...ect...
