Hi everybody!<br />I have an 89 Force (90HP) and this winter took it to "service" the thing is, that the mechanich left it running fine, but without load, as soon as I tried to tow an skier the motor had trouble to rev up, it´ll get stuck at 2500 rpms... (that didnt happende before)<br /><br />So, I took off the top howsing and try to "adjust" the nozzle on all 3 carbs (i Think it worked).... then tried to adjust the timing advance slider (I not sure of the name, the one close to the stator and a adjusting screw). I turned the screw 1/2 turn to the right! and the boat semmed to get better at low rpm, allowing me to toe the skier better...<br /><br />The question is.. what did I do?? advanced the spark?? or delay it??? Is it dangerous regarding overhating?? Maybe I shouldn´t be trying to adjust this, but sadly here in mexico we don´t have good mechanics (at least in my city)... Any advice?? or how can I improve the power on my boat??<br /><br />Thanks for your time!!<br /><br />Best regards from mexico!<br /><br />Amador

Re: Timing Adjustment

Incorrect adjustment of the ignition timing can indeed destroy an engine so do not adjust it unless you fully understand the process. Timing and carburetors must also be synchronized with each other for proper performance. Unless you have a timing light (strobe) you can't properly set timing. Without a service manual you also can't properly perform what's called "link and sync" which is the timing and carburetion adjustment process I mentioned.
