I am new here, My Name is David, and I was given a maxum boat. It's a 1700 series with an 85hp force. Do not know anything about the boat and specifications. What fuel ratio is and how much fuel it takes and really need a manual on the boat. Don't know where to start. If anyone out there can help me I certainly would appreciate it..
I emailed someone when I first got my 1989 Maxum 1700. Same motor too. Finally got it on the water after a year of working/modding parts. Half of anything isn't available any more. 50:1 ratio is right, but my fuel tank states 21 gallon on the plate thats on the fuel tank. 12 sounds more like it as I tried to full it up from empty and it only took 9.5 gallons. Threw my ratio off a bit too. Ended up being about 38-40:1. I'll see if I still have the manual when I get home tonight.
Did you verify the tank contents by the gauge or by some other means, like dipping the tank or running it empty? It might be a 21 gallon tank half empty with a gauge that reads empty due to a gauge or fuel sender issue.
No. Haven't gotten that far yet. Had to mod a plate for the lower unit to seal the shift rod. Now I have a carb spitting fuel. Probably needs a good cleaning and the float needle checked.
