[QUOTE=keith;232693]About the silicone. I wasn't too excited to hear it but it is sandwiched between the outdrive and the transom so I thought it could be ok. I could take it off and re-seal it. Do you think it is necessary right away?
Just a few notes on this-
If you are saying he added silicone to the outside sealing surface I guess he did it as an additional safety measure. When you install that transom assembly you use a gasket from merc and that does the sealing work and gives you the right tolerances for torquing down the bolts. If the transom sealing surface was getting less than perfect he may have just added the silicone and, like others above, I would have used something else, but don't consider it a big liability if the job was done right.
You are looking at pulling the motor to redo that job so unless it is really stressing you out Or you are seeing water coming in may want to hold off. There are several failure points on that IO so every so often I would pull the boat, completely dry the bilge and then relaunch and run at the ramp and just keep a really close eye on everything for a few minutes. I always found the best way to inspect that motor/bilge was at night with a flashlight. The few times I was chasing down a leak it was much easier to find this way.
I just sold mine but loved the power package. I had a 5.7 and the same drive you have. They require a bit more vigilance but will treat you well if you do the same.
Feel free to pm me. I think I have a pdf for the shop manual for the Alpha 1. Very good thing to have around.
