1984 Bayliner Trophy Bass Boat and 85 HP Force Motor

Featured Replies

Hey guys hope someone can help me with a few questions! I bought a 1984 Trophy last year that has a 1984 force 85 hp motor on it. It is my first boat and I want to make sure that I am taking all the precautions to ensure its performance. The lower unit was drained last fall but other than that I don't know what the guy did to winterize the motor. What are my steps to get it fishing ready this spring? Whats the best oils to use and fuel? I have been trying to do as much research as I can and I keep getting different answers. Some guys are telling me that it I have to mix the fuel 50.1, others 100.1, and i have had a couple guys tell me that its oil injected and as long as the oil reservoir is full it will be fine. NOT WHAT IVE BEEN LOOKING FOR! I went in on the boat with my father-in-law and was not there when it was transferred, the previous owner said that they motor was gone through the year before my a master mechanic and it ran good. They did hook it up to a garden hose and the father-in-law said it ran good. The inside of the motor is very clean and looks to be well maintained but i just want to make sure that I am doing everything right before I get it in the water. Thanks in advance for your help!!!

I think you've already named the source for the information you need.  Do you have the receipt, or at least the name of this mechanic?
