Hi everyone!!! I am new to boating, Just got my boat up and going yay!!!! now time to fine tune this thing. I have a 1980 16ft checkmate ski boat. the prop I am using right now is a 19 pitch. the boat tops out at 38mph and only goes 5000 RPM WOT. and it is not doing good with a tube. What prop...
OK, need some help on this one.... what am I missing here. lol! I have a 80-82 not sure of exact year of motor 140hp bubble back. I have put a new impeller on it and a new thermostats.. The motor starts and runs, but runs hot after about 2 mins or about 100 yards at the lake. It is shooting hard...
I have a 1979 Johnson 115hp. I changed the impeller. Put new plugs in. I took it out for the first time yesterday. It would not idle very well. so I turned up the idle about 2 turns. after that I ran on the lake for about a hour. worked perfect. stopped to fish that is when every thing went...
