First time posting. I recently had the sterndrive bellows replaced by the V-P dealer here in Homer, AK. This is a 2001 5.0i engine and the out-drive is dup-prop. Don't believe the man ever went into the boat, just removed the drive and 'intermediate houising." Now the temp gauge and the oil pressure gauge start out at normal and slowly climb to dangerous levels. Then, after 1-2 minutes, they both drop back to normal and the whole scarry thing starts over. Also, the "audible alarm" constantly makes a very low volume beep at 1 sec intervals. It's hard to hear unless the hatch is open. I have stopped the boat/engine, etc. and it appears that all is well except for the above. I asked the dealer when it first started happening and they all said it was a grounding problem. Anybody have any ideas? I checked the grounds for the meters and they are fine. Seems to me that there is something in the drive area which might be causing this as that is the only thing he worked on.
