Timeing mod issue
i have a question/ problem i did the timeing mod again on my new 08 motor with 07ecu (6 degrees)put it all back together and fired it up. when i hit the throttle it will just keep escalating higher and higher like its runnig away. I have removed the wheel and check it several times and every thing was correct. i dialed it back to the stock setting and it is fine. throttle works like it should. my question is what could be causeing this? detonaion or something else I have not tried it with the boat in the water only on land . Thanks

dumb question.... did you put an 07 or 08 timing wheel in it..... if you didnt put an 07 timing wheel in it... you are running roughly 10 degrees advanced timing

I dont understand how the wheels make a difference. I am interested in knowing how or why though.

interesting i thought the wheels were all the same im positive the advancement was only made in the ecu but i could be wrong.
by the way fire you have nothing to worry about that symptom is a side effect of what you have done it can be rectified slightly as has been suggested elswhere you posted its not so noticeable on the water.

Does it totally keep reving up or just a high idle out of the water?
Mine would sorta do the same thing on the hose out of the water. Blip the throttle and it would rev up and only settle down to about 3500 rpm's.
Start by backing off the throttle stop screw about 1/2 turn. I think it took a good full turn on my ski to settle it down. Even now, if I blip the throttle and blip it again before it settles down it seems to want to hang. This only happens out of the water. In the water there's no issue at all.
