"I have owned inboard SBC boat
"I have owned inboard SBC boats all my life and done my own maintenance. I recently purchased a 93 Horizon with a yahm 200 on the back (i think it is the same year) I will post the serial tongiht. But, I have a couple of questions 1. where can I get a manual for this engine is there a place online that I can download one from? 2. what is typical compression? 3. What is the fuel to oil mixture (the Automix system has been disconnected ) ? 4. I have a tach but it is busted, the wiring is good but, what kind of tach can I use to replace this? I have a tach with a selecter switch on the back 4,6,8 cylinders will this work? After I can determing RPM's what is WOT supposed to be for this engine? What is the gear ratio in the lower?
Thanks in advance"
