[FONT="]My VE90MLETS cranks and idles normally. However, when I take off and get on plane the engine loses power and seems to be "missing" after approximately 15 seconds. I back off of the throttle and come to an idle for 15 or so seconds then take off again. The engine seems to have full power but loses it after 15 or so seconds. I am again able to bring her to idle, take off, and then lose power. This process seems to be able to be repeated in the same manner as much as needed to get back to the boat dock. The oil tank has plenty of oil in it. I think the amount of "blue smoke" coming from the exhaust at idle is normal to indicate the engine is getting oil. Important to note: The tachometer indication has been intermittent for 10 years now. It might work fine for 10 minutes, stop working for five minutes, bounce around a minute or two, etc. A mechanic told me years ago some electrical part (don't remember what part) might be going bad and may eventually have to be replaced. Any ideas?[/FONT]
