While turning over engine noticed the tach was going backwards (counterclockwise) then when the engine started, went back to normal. Dont think this has been going on. Have had the engines in and out a couple of times lately. Did I miss something?

mine do this also, never been a "problem", just a wierd thing, old race car used to do this too...

Did you also have you boat worked on by Profile?

Can't say that I have, just seems like some gremlins may be lurking....

It's a voltage thing.....................low voltage typicaly under 10.5 volts makes the gauges act funny. Check all connections but should be ok...........

I will check this. As a matter of fact the battery was low at the time and had the charger on "start" when I noticed this. Now battery is charged and will try again. thanx

LMAO ....
